The FDA will be allowing certain people to receive a second booster of an updated COVID-19 vaccine designed to tackle the omicron variant. 

The change in allowing a second booster is limited to those 65 and older who received their first shot of either the Moderna or Pfizer-BioNTech bivalent vaccine at least four months ago, or those with weakened immune systems who received their first shot at least two months ago. The FDA is expected to announce its decision within the next two weeks. 

Looking toward the future, the FDA has decided to focus on preparing for a yearly booster campaign with updated vaccines to combat the latest COVID-19 variant. However, those who received their initial shot with a bivalent booster last year may welcome the opportunity for an extra layer of protection with a booster shot. 

This change will bring the U.S. more in line with the approach taken by Britain and Canada, which is what some vaccine specialists have been urging — especially with the ample of supply of vaccines. Read the NPR article.
