The New York Times: U.S. Health Officials Clear Second Booster for Those 50 and Older


The FDA has approved a second booster COVID-19 vaccine dose for people 50 and older and some people with underlying conditions. This decision comes as a result of months of scientific debate on the necessity and efficacy of a 4th booster shot. Evidence suggests that the third booster surge saved thousands of lives during the Omicron variant winter surge. So a fourth booster shot is expected to provide similar protection in case of another surge in cases. A study from Israel found that 328,597 people aged 60 to 100 years old who received a second booster had 92 die of COVID-19 while 234,868 people of the same age range who only had one booster had 232 people die of COVID-19. Despite evidence such as this that shows the efficacy of a second booster, the FDA’s decision was complicated because it is not clear yet how long a second booster’s protection will last. Also, some experts argue it is better to focus on the development of a modified vaccine that is more effective against new variants rather than approving additional doses of the same vaccine that offer marginally new protection.
