On September 27, Joe Biden, US President, received a Covid-19 vaccine booster. The US President got a third Pfizer dose at the White House. This comes in line with the recently approved health guidelines. It allows boosters for those 65 or older. Biden said, the problem, is that a significant chunk of Americans continue to refuse even one shot of the vaccine. On September 24, Centers for Disease Control and Prevention (CDC) said that data on Moderna and J&J boosters would be evaluated \"in the coming weeks.” Watch the video to know more about the booster dose.
