As flu season approaches, so do the many misconceptions about flu vaccines. Unfortunately, these myths often keep people from getting the protection they need. Every year, millions of people get sick with the flu, and many of these cases could be prevented with a simple flu shot. Let’s debunk some of the most common myths about flu vaccines, so you can make an informed decision and stay healthy.

Myth: The Flu Shot Can Give You the Flu

Fact: You cannot get the flu from the flu shot. The vaccine contains inactivated (killed) viruses or, in the case of the nasal spray, weakened viruses that cannot cause illness. While some people may experience mild side effects like soreness at the injection site or a low-grade fever, these are not the flu—they’re signs that your body is building protection against the virus.

Myth: Healthy People Don’t Need the Flu Vaccine

Fact: Even if you're in perfect health, getting the flu shot is important. The flu can cause serious complications even in healthy individuals, and by getting vaccinated, you’re also protecting those around you—especially the elderly, young children, and people with weakened immune systems. Flu vaccines help reduce the spread of illness, and when more people are vaccinated, it protects the entire community.

Myth: The Flu Vaccine Isn’t Effective

Fact: While flu vaccines are not 100% effective, they significantly reduce the severity and duration of flu symptoms if you do catch the virus. Each year, the vaccine is designed to protect against the most common strains. Even when there’s a mismatch between the vaccine and the circulating strain, vaccinated individuals tend to have less severe illness than those who are not vaccinated. According to the CDC, flu vaccines prevent millions of flu cases each year.

Myth: I Got the Flu Shot Last Year, So I Don’t Need It This Year

Fact: Flu viruses change from year to year, and the vaccine is updated annually to protect against the strains most likely to circulate. Additionally, immunity from the flu shot fades over time, so getting vaccinated every year is essential for maintaining the best protection.

Myth: It’s Too Late to Get Vaccinated After Flu Season Starts

Fact: While getting vaccinated early in the season (around October) is ideal, it’s never too late. Flu season can last into the spring, and even if you get vaccinated later in the season, you can still benefit from protection.

Myth: Flu Vaccines Contain Harmful Ingredients

Fact: Flu vaccines are rigorously tested for safety. Some vaccines contain trace amounts of preservatives like thimerosal to prevent contamination, but studies have shown that these ingredients are safe in the small amounts used. If you’re concerned, preservative-free flu vaccine options are available.
