Flu Vaccination - Women in Iowa

Iowa

The flu vaccine helps protect people against seasonal influenza viruses (known as the flu) that may lead to severe complications. Estimates suggest that during the 2022-2023 flu season, vaccines prevented 6 million flu-related illnesses and 65,000 hospitalizations associated with influenza in the United States. 

While all women are at risk of developing complications from influenza (such as pneumonia and sinus and ear infections), pregnant women are at greater risk of severe illness and hospitalization. Influenza-related complications among pregnant women can lead to 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 U.S. in 2015 was approximately $11.2 billion. Flu vaccination is highly cost-effective among pregnant women.

According to America’s Health Rankings analysis, the prevalence of flu vaccination 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 who have an income less than $25,000; the prevalence is higher with each increase in income level.
• 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 both their own health and the health of their child. Use the Centers for Disease Control and Prevention’s Flu Vaccine Finder tool to find a flu clinic near you.

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