Flu Vaccine Recommendations

The Centers for Disease Control and Prevention (CDC) recommends that the single best way to prevent the seasonal flu is to get an annual influenza vaccination. The CDC and the state of New Jersey recommend vaccinations for the seasonal flu as soon as possible to allow ample time for the body to make antibodies that protect against the seasonal influenza virus infection.

Anyone who wants to reduce their chances of getting the flu should get vaccinated. Certain people should get vaccinated because they are at high risk of having serious flu-related complications or because they live with or care for high-risk persons. These people include:

  • Pregnant women
  • People 50 years of age and older
  • People of any age with certain chronic medical conditions such as bronchitis, asthma, diabetes or other conditions which compromise immune function
  • People who live with or care for household contacts of persons at high risk for complications from the flu (see above) and home caregivers of children less than six months of age (these children are too young to be vaccinated)

According the CDC, it is safe to receive both the COVID-19 vaccine/booster and flu vaccine during the same time frame.

Get Your Flu Vaccine 

The flu shot is an inactivated vaccine (containing killed virus) that is given with a needle in the arm. The flu shot is approved for use in people older than six months, including healthy people and people with chronic medical conditions. You can receive a flu shot even if you currently have symptoms of a cold, as long as you do not have a fever.

Flu shots at FluFest are free for students and employees (including Princeton retirees and affiliates).

The vaccine available at FluFest will be an injectable quadrivalent vaccine, approved for all adults, immunocompromised individuals, and pregnant women. For more information about influenza and vaccines, please visit the CDC at

The high dose flu vaccine marketed for older adults will not be available at FluFest. Given that there is significant benefit to individuals of all ages to the quadrivalent shot we are providing, we would strongly discourage delaying flu immunization to acquire the specialized flu shot.

Information for Dependents

Immunizations are available for dependents aged 12 years and older who have been vaccinated for COVID-19 and in compliance with the University’s visitor policy. We will not be able to provide flu vaccine for dependents under the age of 12.
