Flu Vaccination - Women

Flu Vaccination - Women in United States

United States

The flu vaccine helps protect people against seasonal influenza (flu) viruses that may lead to severe complications. The Centers for Disease Control and Prevention (CDC) estimates that during the 2021-2022 flu season, vaccines prevented 1.8 million illnesses and 22,000 hospitalizations associated with influenza. 

While all women are at risk of complications from influenza (including pneumonia and sinus and ear infections), pregnant women are at greater risk of severe illness and hospitalization from the flu. Influenza-related complications among pregnant women can lead to an increased risk of preterm delivery, low birth weight infants and other complications. Among pregnant women, the flu shot reduced the risk of being hospitalized with the flu by an average of 40% during 2010-2016. Getting the flu vaccine while pregnant also helps protect babies from flu illness in the first several months after their birth, when they are too young to get vaccinated. 

The annual economic impact of influenza on the United States in 2015 was approximately $11.2 billion. A 2019 study found that among adults ages 18-64, flu vaccinations saved between $8,000 and $39,000 per quality-adjusted life-year (QALY). The same study found that vaccinating pregnant women saved between $85,000 and $260,000 per QALY, depending on the severity of the flu season. Flu vaccination is highly cost-effective among pregnant women.

According to America’s Health Rankings data, flu vaccine coverage is higher among:

• Women ages 35-44 compared with women ages 18-34. 
• Non-Hispanic Asian women compared with non-Hispanic Black women. 
• College graduates compared with women who have less than a high school education. 
• Women with an annual household income of $75,000 or more compared with those with an income less than $25,000. 
• Women living in metropolitan areas compared with those in non-metropolitan areas.

Strategies to increase flu vaccination among women include:

• Encouraging health care providers to discuss flu vaccination with patients. Negative views of the flu vaccine are a major reason for not getting vaccinated, particularly among pregnant women. Patients are more likely to get vaccinated when providers recommend, offer and discuss flu vaccination with them. 
• Providing client reminders for patients who have previously received vaccinations. 
• Providing free or reduced-cost vaccinations. Most insurance plans cover the flu vaccine. However, removing cost as a barrier for those without health insurance can increase vaccination rates.
• Increasing awareness through campaigns. The CDC provides seasonal flu vaccination campaign materials to assist partners in communicating the importance of vaccination. 

The American College of Obstetricians and Gynecologists strongly recommends that pregnant women, or those expecting to be pregnant during flu season, get vaccinated to protect their own and their child's health.

Healthy People 2030 has a goal to increase the proportion of people who get the annual flu vaccine.
