This report summarizes all recommendations from CDC’s Advisory Committee on Immunization Practices (ACIP) for the use of lyophilized CVD 103-HgR vaccine (CVD 103-HgR) (Vaxchora, Emergent BioSolutions, Gaithersburg, MD) in the United States. The live attenuated oral cholera vaccine is derived from: Vibrio cholerae O1 and is administered in a single dose. Cholera is a toxin-mediated bacterial gastrointestinal illness caused by toxigenic V. cholerae serogroup O1 or, uncommonly, O139. Up to 10% of infections manifest as severe cholera (i.e., cholera gravis), profuse watery diarrhea that can cause severe dehydration and death within hours. Fluid replacement therapy can reduce the fatality rate to <1%. Risk factors for cholera gravis include high dose exposure, blood group O, increased gastric pH (e.g., from antacid therapy), and partial gastrectomy. Cholera is rare in the United States, but cases occur among travelers to countries where cholera is endemic or epidemic and associated with unsafe water and inadequate sanitation. Travelers might be at increased risk for poor outcomes from cholera if they cannot readily access medical services or if they have a medical condition that would be worsened by dehydration, such as cardiovascular or kidney disease. This report describes previously published ACIP recommendations about use of CVD 103-HgR for adults aged 18–64 years and introduces a new recommendation for use in children and adolescents aged 2–17 years. ACIP recommends CVD 103-HgR, the only cholera vaccine licensed for use in the United States, for prevention of cholera among travelers aged 2–64 years to an area with active cholera transmission. Health care providers can use these guidelines to develop the pretravel consultation for persons traveling to areas with active cholera transmission.
Cholera is an acute, watery diarrheal illness, primarily caused by toxigenic V. cholerae serogroup O1 that can be severe and rapidly fatal without proper treatment. CVD 103-HgR, a single-dose, live attenuated oral cholera vaccine derived from V. cholerae O1, is the only cholera vaccine licensed for use in the United States. In June 2016, the Food and Drug Administration (FDA) approved CVD 103-HgR for the prevention of cholera caused by V. cholerae O1 in adults aged 18–64 years traveling to cholera-affected areas (1). In June 2016, ACIP voted to recommend use of CVD 103-HgR for prevention of cholera among adult travelers to areas with active cholera transmission (2). In December 2020, FDA extended the approved usage to include children and adolescents aged 2–17 years (3). In February 2022, ACIP voted to recommend the use of CVD 103-HgR for children and adolescents aged 2–17 years traveling to an area with active cholera transmission. ACIP recommends CVD 103-HgR for prevention of cholera among travelers aged 2–64 years to an area with active cholera transmission. Health care providers can use these guidelines to develop the pretravel consultation for persons traveling to areas with active cholera transmission.
Cholera is a toxin-mediated bacterial gastrointestinal illness caused by toxigenic V. cholerae serogroup O1 or, uncommonly, O139. V. cholerae O1 has an aquatic reservoir, and human infection occurs via ingestion of contaminated water or food (4,5). Direct fecal-oral transmission can occur, but secondary cases from person-to-person transmission are rare if sanitation is adequate (4). The incubation period usually ranges from hours to a few days (4,5).
Infection with toxigenic V. cholerae O1 can cause a range of symptoms. Up to 10% of infections manifest as cholera gravis, profuse watery diarrhea that can cause severe dehydration and death within hours without treatment (4). The case-fatality rate ranges from as high as 50% without treatment to <1% with appropriate fluid replacement therapy (6). Fluid replacement should be based on the degree of volume depletion and ongoing fluid losses. Oral rehydration solution can be used for milder cases, whereas intravenous fluids are needed for severe dehydration or hypovolemic shock. Antibiotics, which have been shown to shorten the duration of illness and fluid requirements, are an adjunct for severely ill patients (4).
A definitive diagnosis of cholera is based on culture of stool or rectal swab specimens. Special transport and culture media not routinely used for stool cultures are needed to isolate V. cholerae. Other stool-based diagnostic tests include antigen tests, darkfield microscopy, and molecular assays. Although certain multiplex gastrointestinal panels used in clinical settings have a target for V. cholerae, these tests are insufficient for diagnosis without serogroup information and confirmation of toxin production.
Recommended measures to prevent cholera infection in cholera-endemic areas include using safe water (i.e., for drinking, brushing teeth, washing and preparing food, and making ice) and eating safe food (i.e., those that are packaged or fully cooked and served hot). Other important prevention measures include washing hands often with soap and safe water and using sanitary methods to dispose of stool (https://www.cdc.gov/cholera/preventionsteps.html).
Cholera is endemic in approximately 50 countries and can cause large epidemics (7). Cholera epidemics are associated with unsafe water and inadequate sanitation. An estimated 1.3–4.0 million cases of cholera and 21,000–143,000 deaths occur worldwide each year (5). CDC’s Travelers’ Health Branch monitors areas with active cholera transmission and updates the list of affected countries monthly (https://wwwnc.cdc.gov/travel/news-announcements/cholera-vaccine-for-travelers).
Epidemiology in the United States and Exposure Risk Among Travelers
Cholera is rare in the United States, although likely underreported. Most U.S. cases occur among travelers to countries where cholera is endemic or epidemic (8). Domestically acquired cases are usually associated with consuming undercooked seafood from coastal waters where V. cholerae species are endemic in the environment, such as along the Gulf Coast (8). During 2012–2018, a total of 64 cases of cholera in the United States were reported to CDC’s Cholera and Other Vibrio Illness Surveillance system; 56 (88%) were travel associated. Five cases (8%) occurred in children and adolescents aged 2–17 years; all were travel associated (9).
Cholera infections among U.S. international travelers are rare because most do not travel to areas with active cholera transmission and are able to access safe water and food at their destination (10). Persons at higher risk for exposure to toxigenic V. cholerae O1 include persons living in or traveling to cholera-affected areas for extended periods, travelers visiting friends and relatives, health care personnel, and cholera outbreak response workers (8,11–13). Cholera can be prevented by exclusive use of safe water and food, frequent handwashing, and adequate sanitation.
Risk for Poor Outcomes from Cholera
Risk factors for cholera gravis include high-dose exposure, increased gastric pH (e.g., from antacids, proton-pump inhibitory therapy, or partial gastrectomy), and blood group O (14,15). Many travelers will not know their blood group at the time of consultation; however, an estimated 45% of persons in the United States have blood group O (16). Pregnancy is a risk factor for poor outcomes from cholera infection (17). Travelers also can be at increased risk for poor outcomes from cholera if they cannot readily access medical services or if they have a medical condition that would be worsened by dehydration (e.g., cardiovascular or kidney disease).
CVD 103-HgR is a single-dose, live attenuated oral cholera vaccine derived from V. cholerae O1. In June 2016, FDA approved CVD 103-HgR for the prevention of cholera caused by V. cholerae O1 in adults aged 18–64 years traveling to cholera-affected areas (1). In December 2020, FDA extended the approved usage to include children and adolescents aged 2–17 years (3). CVD 103-HgR is the only cholera vaccine licensed for use in the United States; all ACIP recommendations in this report pertain to this formulation.
A previous formulation of CVD 103-HgR with identical phenotypic and genomic properties was licensed in other high-income countries under the trade names Orochol and Mutachol (18). Production was discontinued in 2003 for business reasons (i.e., not for safety or efficacy concerns) (2). Four other oral cholera vaccines (Dukoral, Shanchol, Euvichol, and Euvichol-Plus) are prequalified by the World Health Organization but are not available in the United States (19).
Immunologic Response to Cholera and Cholera Vaccine
Protection against cholera is largely serogroup specific, and serogroup specificity is defined by the O-specific polysaccharide component of V. cholerae lipopolysaccharide (20). Infection with V. cholerae O1 protects against symptomatic reinfection, at least for a few years (21,22). A precise and easily measurable long-term correlate of protection against cholera remains elusive because protection is thought to be mediated by immune responses at the intestinal mucosal surface (20). The serum vibriocidal antibody response is commonly used as a correlate of protection, although it is most likely a surrogate marker (23). The vibriocidal response is primarily directed to the O-specific polysaccharide component of V. cholerae (20,24). O-specific polysaccharide-specific memory B-cells also are associated with long-term protection but are more challenging to measure than serum antibodies (25).
Two ACIP work groups related to cholera vaccination met regularly to review relevant data and prepare draft policy recommendations for ACIP consideration. The Adult Cholera Vaccine Work Group (active August 2015–June 2016) focused on use of CVD 103-HgR among adults aged 18–64 years. The Pediatric Cholera Vaccine Work Group (active October 2020–February 2022) focused on use of CVD 103-HgR among children and adolescents aged 2–17 years. The work groups included two ACIP voting members, ex officio and liaison organization representatives, and consultants. The work groups had members with expertise in cholera, travel medicine, immunology, infectious diseases, epidemiology, obstetrics and gynecology (adult work group only), pediatrics (pediatric work group only), public health, and vaccination safety. The work groups convened via regularly scheduled teleconferences to discuss the epidemiology and immunology of cholera, data on the safety and efficacy of CVD 103-HgR in the target population, feasibility of administration, and other considerations.
ACIP used the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach to evaluate the certainty of evidence for selected benefits and harms prespecified by each work group (Table 1) (26). For both age groups, ACIP considered evidence regarding safety and immunogenicity of the available formulation of CVD 103-HgR (27–31). For adults aged 18–64 years, ACIP also considered evidence regarding the efficacy of the current formulation of CVD 103-HgR (data were limited to adults aged 18–45 years) and evidence regarding efficacy and safety of the previously available formulation of CVD 103-HgR (2,32).
In February 2018, ACIP adopted the Evidence to Recommendations (EtR) framework (https://www.cdc.gov/vaccines/acip/recs/grade/etr.html) to facilitate all deliberations related to its recommendations and provide transparency regarding factors that influence policy decisions (33). ACIP deliberations regarding use of CVD 103-HgR in adults aged 18–64 years preceded adoption of the EtR framework; therefore, recommendations for this age group did not follow the EtR framework. ACIP deliberations regarding use of CVD 103-HgR in children and adolescents aged 2–17 years followed adoption of the EtR framework and considered the importance of cholera as a public health problem, benefits and harms of CVD 103-HgR, values of the respective population, acceptability, feasibility, resource use, and equity. Expert judgment was considered when evidence was not available; adult and pediatric Cholera Vaccine Work Group presentations to ACIP were examined (Table 2).
The efficacy of the current formulation of CVD 103-HgR against moderate or severe diarrhea (defined as cumulative fecal output >3 L after oral toxigenic V. cholerae O1 experimental challenge) in adults aged 18–45 years is estimated to be 90% at 10 days after vaccination and 80% at 3 months after vaccination (32). A randomized controlled trial of the previous formulation with identical phenotypic and genomic properties (manufacture production discontinued in 2003) demonstrated similar efficacy (34). No studies directly assessed vaccine efficacy among children and adolescents aged 2–17 years; only immunogenicity data were available. In both adults aged 18–64 years and children and adolescents aged 2–17 years, the current formulation of CVD 103-HgR induced serum vibriocidal antibody seroconversion (a fourfold or more rise in titer) in >93% of recipients on day 11 (27,29–31).
In clinical trials conducted using the current formulation, no vaccine-related serious adverse events were reported among participants aged 2–64 years (27,29–31). In clinical trials among adults aged 18–45 years, solicited adverse events were more commonly reported by CVD 103-HgR recipients than by placebo (i.e., buffer alone) recipients ≤7 days after vaccination and included tiredness (31.3% versus 27.4%; mostly mild or moderate), headache (28.9% versus 23.6%; mostly mild), nausea or vomiting (18.3% versus 15.2%; mostly mild), and diarrhea (3.9% versus 1.2%; mostly mild) (31,35). In the clinical trials among children and adolescents aged 2–17 years, any solicited adverse event ≤7 days after vaccination was reported by 55.1% of vaccine recipients and 50.7% of placebo recipients. Solicited adverse events more commonly reported by vaccine than placebo recipients aged 2–17 years included tiredness (35.7% versus 30.7%; mostly mild), headache (27.4% versus 25.3%; mostly mild), abdominal pain (27.8% versus 18.7%; mostly mild), and lack of appetite (21.4% versus 14.7%; mostly mild) (27,29,35).
GRADE Quality Assessment (Certainty) of the Evidence
Children and Adolescents Aged 2–17 years
For prevention of cholera diarrhea (moderate to severe; any severity), the available body of evidence consisted of randomized controlled trials of the current formulation of CVD 103-HgR; this evidence indirectly assessed vaccine effectiveness via immunobridging and was deemed GRADE evidence type 2 (i.e., moderate certainty). For safety outcomes, the data were more limited; the small sample size (468 vaccine recipients and 75 placebo recipients) resulted in imprecise pooled effect estimates, and the final evidence was type 3 (i.e., low certainty) (https://www.cdc.gov/vaccines/acip/recs/grade/cholera-CVD-103-HgR-child-2-17-years.html).
Adults Aged 18–64 Years
Through the systematic review and quality assessment, the adult work group in 2016 found high-certainty evidence that the vaccine is highly effective and low-certainty evidence that it is safe. The body of evidence, which included studies with the currently available CVD 103-HgR formulation and studies with oral toxigenic V. cholerae O1 challenge, indicated high vaccine efficacy and was judged to be GRADE evidence type 1 (i.e., high certainty). For safety outcomes, the data were more limited because relatively few persons had received the current vaccine formulation. Few studies evaluated coadministration with other vaccines or medications; all used the previous formulation of CVD 103-HgR (36). Because of these limitations, the GRADE evidence rating for safety outcomes was judged to be type 3 (i.e., low certainty) (https://www.cdc.gov/vaccines/acip/recs/grade/cholera-CVD-103-HgR.html).
Both ACIP work groups assessed the risk for cholera in U.S. travelers through review of the epidemiology of cholera and consideration of expert judgment. Cholera is rare among travelers returning to the United States from cholera-affected areas, and cholera is treatable if medical services are readily accessible (6,8). However, certain populations are at higher risk for severe toxigenic V. cholerae O1 infection and adverse outcomes (14,15,17). A traveler’s risk for acquiring cholera and developing severe illness might not be clear at the pretravel visit with their health care provider. Although cholera is rare, both work groups concluded that a safe and effective vaccine that can prevent a potentially severe cholera infection can benefit certain travelers. Additional information can be found in the EtR framework regarding children and adolescents aged 2–17 years (https://www.cdc.gov/vaccines/acip/recs/grade/cholera-CVD-103-HgR-child-2-17-years-etr.html) and in the previously published ACIP recommendations for adults aged 18–64 years (2).
Personal Protective Measures
All travelers to cholera-affected areas should consume safe food and water, wash their hands often with soap and safe water, and follow recommended sanitation practices (https://www.cdc.gov/cholera/preventionsteps.html). Travelers who develop severe diarrhea should seek prompt medical care, particularly fluid replacement.
Population Recommended for Vaccination with CVD 103-HgR
ACIP recommends CVD 103-HgR for travelers aged 2–64 years to an area of active cholera transmission. An area of active cholera transmission is defined as a province, state, or other administrative subdivision within a country with endemic or epidemic cholera caused by toxigenic V. cholerae O1 and includes areas with cholera activity within the past year that are prone to recurrence of cholera epidemics (2). An area of active cholera transmission does not include areas where only rare imported or sporadic cases have been reported. CDC’s Travelers’ Health Branch monitors areas with active cholera transmission and updates the list of affected countries monthly (https://wwwnc.cdc.gov/travel/news-announcements/cholera-vaccine-for-travelers).
CVD 103-HgR is not recommended for travelers who are not visiting areas with active cholera transmission. Most travelers from the United States do not visit areas with active cholera transmission (https://wwwnc.cdc.gov/travel/diseases/cholera#areas). No country requires vaccination against cholera as a condition for entry.
CVD 103-HgR Booster Doses
No data exist about the safety or efficacy of preventing cholera with booster doses of the currently licensed CVD 103-HgR. The duration of protection conferred by the primary dose beyond the 3-month period evaluated in adults aged 18–45 years is unknown. ACIP does not have a recommendation regarding use of booster doses.
In an open label study of the previous formulation, 31 Swiss adults aged 23–48 years were given a single booster dose 15 or 24 months after the initial dose (37). One patient reported an adverse reaction (i.e., moderate diarrhea). Efficacy was not directly assessed, and a minority (i.e., approximately 25%) of participants experienced serum vibriocidal antibody seroconversion (a fourfold or more rise in titer) after the booster dose. The relation between serum vibriocidal antibody levels and efficacy has not been established beyond 3 months after vaccination.
Administration of CVD 103-HgR
Health care providers should see the package insert for detailed administration instructions (35). CVD 103-HgR should be given ≥10 days before travel to an area with active cholera transmission. Recipients should avoid consuming food or drinks for 60 minutes before or after vaccine administration.
Administration instructions differ for recipients aged 2–5 years versus recipients aged 6–64 years. For all recipients, dose preparation begins with reconstituting the buffer sachet in 100 mL of cold or room temperature purified noncarbonated, nonflavored bottled or spring water. Tap water should not be used because it contains chlorine that can affect the viability of orally ingested live attenuated bacterial vaccines. For recipients aged 6–64 years, mix the active component (i.e., lyophilized V. cholerae CVD 103-HgR) with the full volume of reconstituted buffer solution (100 mL). For children aged 2–5 years, discard one half of the reconstituted buffer solution (50 mL) before adding the active component; this step reduces the vaccine volume (i.e., to aid consumption) while maintaining the specified potency (38).
To improve palatability, approximately all (93%) children and adolescents aged 2–17 years in the clinical trial added Pure Via brand stevia (1 g), a plant-derived sweetener, to the reconstituted CVD 103-HgR (39). During the January 12, 2022 ACIP meeting, the manufacturer presented unpublished data demonstrating that CVD 103-HgR should not be mixed with foods and drinks (e.g., rice cereal, applesauce, apple juice, or milk), because of excessive foaming, or with medicine flavorings that contain propylene glycol, which is bactericidal (38). The data support that the vaccine can be mixed with sucrose (table sugar, 1–4 g or ¼ to 1 teaspoon) or stevia sweetener (1 g or 1 packet; brands tested: Pure Via, Sweet Additions, Truvia, Splenda Naturals, and Sweetleaf) without the vaccine potency dropping below the minimum specification (38). Health care providers can consider administering CVD 103-HgR with sucrose or stevia sweetener to aid consumption of the full dose, although guidance regarding the use of sweeteners is not included in the package insert at the time of this publication.
Coadministration of Other Medications or Vaccines with CVD 103-HgR
Antibiotics. Because the immune response to CVD 103-HgR relies on the live attenuated vaccine organisms replicating within the small intestine, antibiotics administered before or after the vaccine might diminish the vaccine’s effectiveness. The outcome will depend on factors such as the timing, half-life, and spectrum of the antibiotic. The optimal interval between CVD 103-HgR and receipt of antibiotics is unknown.
The package insert specifies that CVD 103-HgR should not be given to patients who have received oral or parenteral antibiotics during the preceding 14 days (35). A duration of fewer than 14 days between stopping antibiotics and giving CVD 103-HgR might be acceptable under certain circumstances, such as if travel cannot be avoided before 14 days have elapsed after stopping antibiotics.
The package insert does not specify an optimal minimum duration between completion of CVD 103-HgR and starting antibiotics (35). In certain circumstances, antibiotics might be clinically necessary after the vaccine (i.e., to treat an unrelated infection). Approximately all (>93%) vaccine recipients aged 2–45 years had vibriocidal antibody seroconversion ≤10 days after vaccination (27,29,31).
Antimalarials. Chloroquine might diminish the immune response to CVD 103-HgR (35). The manufacturer recommends that CVD 103-HgR be administered ≥10 days before starting chloroquine. Doxycycline, a tetracycline antibiotic, is often used for malaria prophylaxis. The optimal duration between completion of CVD 103-HgR and starting doxycycline is unknown.
Other Vaccines. No data are available on concomitant administration of the currently licensed CVD 103-HgR with other vaccines, including the enteric-coated oral live-attenuated typhoid vaccine (Ty21a, marketed as Vivotif [Emergent BioSolutions, Gaithersburg, MD]). The expert opinion of the ACIP work group postulated that CVD 103-HgR buffer might interfere with the enteric-coated Ty21a formulation and concluded that taking the first Ty21a dose ≥8 hours after ingestion of CVD 103-HgR might decrease potential interference of the vaccine buffer with the Ty21a vaccine.
Contraindications, Precautions, and Other Considerations for Use of CVD 103-HgR
Allergy. CVD 103-HgR should not be administered to persons with a history of severe allergic reaction (e.g., anaphylaxis) to any component of this vaccine or to any cholera vaccine.
Age. No data exist about the safety and effectiveness of the currently available CVD 103-HgR vaccine in children aged <2 years or in adults aged ≥65 years.
Pregnancy and Breastfeeding. No data exist on use of the currently licensed CVD 103-HgR during pregnancy or while breastfeeding. Prospective travelers who are pregnant and their clinicians should consider the risks associated with traveling to areas with active cholera transmission. The V. cholerae O1 vaccine strain is not absorbed systemically; thus, maternal exposure to the vaccine is not expected to result in exposure to the fetus or breastfed infant to the vaccine. However, the vaccine strain might be shed in stool for ≥7 days after vaccination, and theoretically, the vaccine strain could be transmitted to an infant during vaginal delivery. A breastfed infant theoretically could receive benefit from maternally derived vaccine antibodies present in maternal milk.
Persons with Altered Immunocompetence. No data exist on use of the currently licensed CVD 103-HgR formulation in immunocompromised populations. Persons with altered immunocompetence and their clinicians should consider the risks associated with traveling to areas with active cholera transmission. Consultation with a specialist in immunology or infectious diseases should be considered if travel to an area with active cholera transmission is necessary. ACIP generally advises against administering live vaccines to persons with most forms of altered immunocompetence (https://www.cdc.gov/vaccines/hcp/acip-recs/general-recs/immunocompetence.html).
A study of the previous formulation of CVD 103-HgR among 38 HIV-positive adults without clinical AIDS in Mali found that vibriocidal seroconversion was slightly lower among HIV-positive than HIV-negative participants (58% versus 71%) (40). No significant differences in occurrence of any systemic adverse events were found between vaccinated and comparison populations.
Shedding and Transmission. CVD 103-HgR is a live, attenuated oral vaccine that can be shed in stool for ≥7 days after vaccination and potentially transmitted to close contacts. During phase I studies of the current vaccine, the vaccine strain was cultured from stool in 11% of vaccine recipients on any day through 7 days after vaccination (18). In the same study, the vaccine strain was not isolated from stool collected from 24 household contacts of vaccine recipients on day 7 after vaccination (18). However, later transmission could have been missed.
Although handwashing after using the toilet and before preparing or handling food are part of CDC’s routine handwashing guidance (41), the package insert specifies that vaccine recipients should wash their hands thoroughly in these circumstances for ≥14 days after vaccination (35). Care providers of vaccine recipients who are diapered or who require assistance with toileting (e.g., younger children) should also follow this recommendation.
Reporting of Vaccine Adverse Events and Additional Information
Adverse events that occur in a patient after vaccination with CVD 103-HgR should be reported to the Vaccine Adverse Event Reporting System (VAERS) regardless of whether the vaccine caused the event is certain. Instructions for reporting to VAERS can be found at https://vaers.hhs.gov/reportevent.html or by calling 1–800–822–7967. Additional information about cholera and CVD 103-HgR is available at https://www.cdc.gov/cholera/index.html.
As new information becomes available on cholera epidemiology and cholera vaccines, ACIP and CDC will review and revise these recommendations as indicated. New information might include, but might not be limited to, licensure of CVD 103-HgR in other age groups or U.S. licensure of other cholera vaccines.

CDC Adoption of ACIP Recommendations for MMWR Recommendations and Reports, MMWR Policy Notes, and Immunization Schedules (Child/Adolescent, Adult)
Recommendations for routine use of vaccines for children, adolescents, and adults are developed by the Advisory Committee on Immunization Practices (ACIP). ACIP is chartered as a federal advisory committee to provide expert external advice and guidance to the Director of CDC on use of vaccines and related agents for the control of vaccine-preventable diseases in the civilian population of the United States. Recommendations for routine use of vaccines for children and adolescents are harmonized to the greatest extent possible with recommendations made by the American Academy of Pediatrics (AAP), the American Academy of Family Physicians (AAFP), the American College of Obstetricians and Gynecologists (ACOG), and the American College of Nurse-Midwives (ACNM). Recommendations for routine use of vaccines for adults are harmonized with recommendations of the American College of Physicians (ACP), AAFP, ACOG, and ACNM. ACIP recommendations approved by the CDC Director become agency guidelines on the date published in the Morbidity and Mortality Weekly Report (MMWR).
