Flu Vaccine How Long Does It Last?
The flu vaccine is an important part of preventing the flu, but how long does it last? The answer to this question depends on a number of factors, including your age, health, and the type of flu vaccine you receive.
1. How Long Does the Flu Vaccine Last for Adults?
For adults, the flu vaccine typically lasts for about 6 months. This means that you should get your flu shot every year, ideally in September or October.
2. How Long Does the Flu Vaccine Last for Children?
For children, the flu vaccine typically lasts for about 4 months. This means that children should get their flu shot twice a year, once in September or October and again in January or February.
3. How Long Does the Flu Vaccine Last for People Over 65?
For people over 65, the flu vaccine typically lasts for about 3 months. This means that people over 65 should get their flu shot three times a year, once in September or October, again in December or January, and again in March or April.
4. How Long Does the Flu Vaccine Last for People with Chronic Health Conditions?
For people with chronic health conditions, such as asthma, diabetes, or heart disease, the flu vaccine may not last as long as it does for healthy people. This is because people with chronic health conditions have weaker immune systems, which makes them more susceptible to the flu. People with chronic health conditions should get their flu shot every year, ideally in September or October.
Timelines for Different Types of Flu Vaccine
There are two main types of flu vaccine: the inactivated flu vaccine and the live attenuated flu vaccine. The inactivated flu vaccine is made from dead flu viruses, while the live attenuated flu vaccine is made from weakened live flu viruses.
The inactivated flu vaccine is typically recommended for most people, including adults, children, and people over 65. The live attenuated flu vaccine is typically recommended for healthy people between the ages of 2 and 49.
The inactivated flu vaccine typically lasts for about 6 months, while the live attenuated flu vaccine typically lasts for about 4 months.
Factors That Affect How Long the Flu Vaccine Lasts
A number of factors can affect how long the flu vaccine lasts, including:
- Your age: The flu vaccine typically lasts longer in younger people than in older people.
- Your health: The flu vaccine typically lasts longer in healthy people than in people with chronic health conditions.
- The type of flu vaccine you receive: The inactivated flu vaccine typically lasts longer than the live attenuated flu vaccine.

Common Mistakes to Avoid
There are a few common mistakes people make when it comes to the flu vaccine. These mistakes include:
- Not getting your flu shot every year: The flu vaccine is only effective for about 6 months, so it’s important to get your flu shot every year.
- Getting your flu shot too late: The flu vaccine takes about 2 weeks to become effective, so it’s important to get your flu shot in September or October.
- Not getting your child vaccinated: The flu vaccine is safe and effective for children, and it can help protect them from the flu and its complications.
- Thinking that the flu vaccine will give you the flu: The flu vaccine cannot give you the flu. The flu vaccine is made from either dead or weakened flu viruses, so it cannot cause the flu.
Strategies for Increasing Flu Vaccine Uptake
There are a number of strategies that can be used to increase flu vaccine uptake. These strategies include:
- Making the flu vaccine free or low-cost: When the flu vaccine is free or low-cost, more people are likely to get vaccinated.
- Offering the flu vaccine in a variety of settings: The flu vaccine should be offered in a variety of settings, such as doctor’s offices, pharmacies, and workplaces.
- Educating people about the benefits of the flu vaccine: People need to be educated about the benefits of the flu vaccine so that they can make informed decisions about getting vaccinated.
