Researchers from the Commonwealth Fund and Yale School of Public Health tracked age-stratified demographics, risk factors and the dynamics of infection and vaccination to understand the effectiveness of the COVID-19 vaccines nearly two years after they were approved.
COVID-19 booster shots
The Moderna booster dose will be available to vaccinated adults. The Pfizer-BioNTech booster is intended for those 12 years and older.
The U.S. Food and Drug Administration has given a green light to Americans who want to receive a booster dose of a COVID-19 vaccine manufactured by a different company than the one that produced the initial shot they received.
Top U.S. health officials announced a plan Wednesday to begin offering COVID-19 booster shots to Americans starting Sept. 20, with the scheduling of the additional shot to be based on when a person was fully vaccinated. The new round of jabs will be extended to those who received the two-dose vaccine from either Pfizer or Moderna, and can be taken eight months after an individual’s second dose.
