How long does immunity last after you get vaccinated?
Protection from most vaccines lasts a long time.
While we are detecting waning immunity, or protection that wears off sooner than expected for some vaccines, most provide long-lasting, even lifetime protection.
Waning immunity is a problem for the mumps and acellular pertussis vaccines.
We have also always known that tetanus requires regular boosters for good protection and that you need to get a flu vaccine each and every year, even when flu strains in the vaccine don’t.
Immunity from most other vaccines lasts a long time and doesn’t wane or decrease over time.
