COVID-19 Update: Pandemic spread of the 2019 coronavirus disease (COVID-19) is a serious threat to communities and health care systems across the country. As of April 9, nearly 80 COVID-19 vaccine candidates pdf icon[32 pages]external icon were reported to be under development worldwide, primarily in the pre clinical stage. Multiple vaccine technologies are under evaluation, including subunit, nucleic acid, virus vector, and live attenuated virus vaccines. Many of these vaccines target the spike (S) protein of SARS-CoV-2, which is a major virulence factor as it mediates viral attachment and entry to the host cell.

One candidate vaccine is currently in Phase II clinical trials:

  • An adenovirus type 5 vector vaccine, China

Four candidate vaccines are currently undergoing Phase I clinical trials:

  • A messenger ribonucleic acid (mRNA) vaccine (mRNA-1273, Moderna TX, Inc.), U.S.
  • A deoxyribonucleic acid (DNA) vaccine (INO-4800, Inovio Pharmaceuticals, Inc.), U.S.
  • A lentiviral vector vaccine (pathogen-specific aAPC, Shenzhen Geno-Immune Medical Institute), China
  • A lentiviral vector vaccine with cytoxic T lymphocytes (LV-SMENP-DC, Shenzhen Geno-Immune Medical Institute), China

The mRNA and DNA technologies used for the first COVID-19 vaccine clinical trials in the U.S. are novel, with no licensed human vaccine products. These technologies have the advantages of rapid vaccine development and scale-up, and thus have been used to develop candidate vaccines for other pathogens that are emerging or have pandemic potential.

Results of these and additional clinical trials will be necessary to demonstrate safety and efficacy of these and other COVID-19 vaccines in the development pipeline. An Advisory Committee on Immunization Practices (ACIP) COVID-19 vaccine work group has recently been initiated to help inform ACIP’s recommendations on potential use of COVID-19 vaccines in the U.S.

Maintaining Clinical Preventive Services, Including Immunizations, During the COVID-19 Pandemic The COVID-19 pandemic is changing rapidly and continues to affect communities across the U.S. in different ways. Clinicians must maintain access to clinical services in environments that are safe for all. Some of the strategies pdf icon[1 page]external icon used to slow the spread of disease in communities include postponing or cancelling non-urgent elective procedures and using telemedicine instead of face-to-face encounters for routine medical services.

Clinics Working with Children: Health care providers in communities affected by COVID-19 are using strategies to separate well visits from sickexternal icon visits. Examples include:

  • Scheduling well visits in the morning and sick visits in the afternoon
  • Separating patients by placing patients with sick visits in different areas of the clinic or at a different location from patients with well visits
  • Collaborating with providers in the community to identify separate locations for holding well visits for children

Because of personal, practice, or community circumstances related to COVID-19, some providers may not be able to provide well-child visits or vaccinations for all patients in their practice. If a practice can provide only limited well-child visits, health care providers are encouraged to prioritize newborn care and vaccination of infants and young children (through 24 months of age) when possible.

Clinics Working with Adults: Delivery of some clinical preventive services for adults, such as immunizations, requires face-to-face encounters and in areas with community transmission of SARS-CoV-2, these should be postponed except when:

  • An in-person visit must be scheduled for some other purpose and the clinical preventive service can be delivered during that visit with no additional risk.
  • An individual patient and their clinician believe there is a compelling need to receive the service because the potential benefit outweighs the risk of exposure to the virus that causes COVID-19.

CDC is monitoring the situation and will continue to provide guidance for adult recommendations and for pediatric recommendations.

Vaccine Information Statements (VISs): Updated VISs for DTaP (diphtheria, tetanus, pertussis), Td (tetanus, diphtheria) , Tdap (tetanus, diphtheria, pertussis), yellow fever, and multiple vaccines (DTaP, Hib, hepatitis B, polio, and PCV13) have been posted. The multiple vaccines VIS may be used in place of the individual VISs for DTaP, Hib, hepatitis B, polio, and PCV13 when two or more of these vaccines are administered during the same visit. It may be used for infants through children receiving their routine vaccines at age 4–6 years. We encourage providers to begin using these VISs immediately, but stocks of the previous editions may be used until they run out. For more information please visit the VIS website.

MMWR

Progress Toward Measles Elimination in the Eastern Mediterranean Region, 2013–2019: In 1997, during the 41st session of the Regional Committee for the Eastern Mediterranean, the 21 countries in the World Health Organization (WHO) Eastern Mediterranean Region (EMR) passed a resolution to eliminate measles. In 2015, this goal was included as a priority in the Eastern Mediterranean Vaccine Action Plan 2016–2020 (EMVAP), endorsed at the 62nd session of the Regional Committee. To achieve this goal, the WHO Regional Office for the Eastern Mediterranean developed a four-pronged strategy: 1) achieve more than 95% vaccination coverage with the first dose of measles-containing vaccine (MCV1) among children in every district of each country through routine immunization services; 2) achieve more than 95% vaccination coverage with a second MCV dose (MCV2) in every district of each country either through implementation of a routine 2-dose vaccination schedule or through supplementary immunization activities (SIAs); 3) conduct high-quality, case-based surveillance in all countries; and 4) provide optimal measles clinical case management, including dietary supplementation with vitamin A. The April 17 MMWR describes progress toward measles elimination in EMR during 2013–19 and updates a previous report. Estimated MCV1 coverage increased from 79% in 2013 to 82% in 2018. MCV2 coverage increased from 59% in 2013 to 74% in 2018. In addition, during 2013–19, approximately 326.4 million children received MCV during SIAs. Reported confirmed measles incidence increased from 33.5 per 1 million persons in 2013 to 91.2 in 2018, with large outbreaks occurring in Pakistan, Somalia, and Yemen; incidence decreased to 23.3 in 2019. In 2019, the rate of discarded nonmeasles cases was 5.4 per 100,000 population. To achieve measles elimination in the EMR, increased visibility of efforts to achieve the measles elimination goal is critically needed, as are sustained and predictable investments to increase MCV1 and MCV2 coverage, conduct high-quality SIAs, and reach populations at risk for not accessing immunization services or living in areas with civil strife.
