Studies appear to be showing that a vaccines effectiveness is long lasting enough to not need a booster shot.
Originally researchers believed the vaccines would only last around 8 months, but new studies show it may be years.
Studies happening at Rochester Regional Health and The University of Rochester Medical Center are looking into the need for a booster shot.
The reasons for studying the potential need for booster shots is because immunity wanes after time, and because of the new variants found.
A recent study shows immunity may last for years, and those who received the Moderna or Pfizer shots may not need a booster shot.
Studies also show that a person with the vaccine who may become re-infected are likely to have less severe symptoms than those not vaccinated at all.
