Pregnant Women & Influenza (Flu)

A Flu Vaccine is the Best Protection Against Flu

Getting an influenza flu vaccine is the first and most important step in protecting against flu. Pregnant women should get a flu shot and not the nasal spray flu vaccine. Flu shots given during pregnancy help protect both the mother and her baby from flu. Vaccination has been shown to reduce the risk of flu-associated acute respiratory infection in pregnant women by about one-half. A 2018 studyexternal icon showed that getting a flu shot reduced a pregnant woman’s risk of being hospitalized with flu by an average of 40 percent. Pregnant women who get a flu vaccine are also helping to protect their babies from flu illness for the first several months after their birth, when they are too young to get vaccinated. A list of recent studies on the benefits of flu vaccination for pregnant women is available.

A Long Record of Safety for Flu Shots in Pregnant Women

Seasonal Flu Vaccine Safety and Pregnant Women

Flu shots have been given to millions of pregnant women over many years with a good safety record. There is a lot of evidence that flu vaccines can be given safely during pregnancy. CDC and ACIP recommend that pregnant women get vaccinated during any trimester of their pregnancy. It is very important for pregnant women to get the flu shot.

Other Preventive Actions

In addition to getting a flu shot, pregnant women should take the same everyday preventive actions CDC recommends of everyone, including covering coughs, washing hands often, and avoiding people who are sick. Breastfeeding also has many benefits, including helping to protect infants from infections like flu.

Symptoms and Treatment

If you get sick with flu symptoms call your doctor right away. There are antiviral drugs that can treat flu illness and prevent serious flu complications. CDC recommends prompt treatment for people who have influenza infection or suspected influenza infection and who are at high risk of serious flu complications, such as pregnant women and people with asthma, diabetes (including gestational diabetes), or heart disease. Early treatment of flu in hospitalized pregnant women has been shown to reduce the length of the hospital stay.

Symptoms

Flu symptoms include fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills and fatigue. Some people may also have vomiting and diarrhea, though this is most common in young children. People may be infected with the flu and have respiratory symptoms without a fever.

Early Treatment is Important for Pregnant Women

• Treatment should begin as soon as possible because antiviral drugs work best when started early (within 48 hours after symptoms start).
• Antiviral drugs can make your flu illness milder and make you feel better faster. They may also prevent serious health problems that can result from flu illness.
• Oral oseltamivir is the preferred treatment for pregnant women because it has the most studies available to suggest that it is safe and beneficial.
• Antiviral drugs require a prescription from your doctor.
• Having a fever caused by flu infection or other infections early in pregnancy may be linked to birth defects in a baby. In addition to taking antiviral drugs, pregnant women who get a fever should treat their fever with Tylenol® (or store brand equivalent) and contact their doctor immediately.

When to Seek Emergency Medical Care

If you are pregnant and have any of these signs, call 911 right away:

• Difficulty breathing or shortness of breath
• Persistent pain or pressure in the chest or abdomen
• Persistent dizziness, confusion, inability to arouse
• Seizures
• Not urinating
• Severe muscle pain
• Severe weakness or unsteadiness
• Fever or cough that improve but then return or worsen
• High fever that is not responding to Tylenol® (or store brand equivalent)
• Decreased or no movement of your baby
