Why Do COVID-19 Vaccines Keep Changing?

COVID-19 vaccines are updated regularly for a few important reasons:

1. New Variants – The virus changes over time. Updated vaccines target the most recent strains to stay effective.

2. Waning Immunity – Protection from earlier shots fades, so boosters help maintain strong immunity.

3. Better Technology – New versions may offer improved protection, fewer side effects, or easier storage.

   
   
   
   

Just like the flu shot, staying up to date helps protect you and your community.
