US Allows Covid-19 Booster Shots For All Adults
The United State on November 19 announced that it has decided to give booster doses of Covid-19 vaccine to all adults for more protection from the infection. The booster shots will be administered to those adults who've received their second doses of the vaccine six months ago. ''Booster shots have demonstrated the ability to safely increase people's protection,'' said Rochelle Walensky, the Centres for Disease Control and Prevention's director.
