Who are the people who need a fourth dose of the vaccine? The New York Times says that the only people allowed to take a fourth dose in America are those with weak immune systems  As the number of coronavirus cases continues to decline across the United States, people's immunity is likely to decline as well, especially after many studies have found that booster doses, although they were successful in reducing deaths and hospitalizations, their effectiveness against infection wanes.  And the American newspaper " The New York Times " says in a report that as of now, the only people allowed to take a fourth dose in America are those who suffer from weak immune systems, and these include adolescents and adults who have undergone organ or stem cell transplants. Those who are on chemotherapy for cancer, or those with advanced or untreated HIV/AIDS, or those taking immunosuppressive drugs.  It is difficult to predict when - or if - the US Food and Drug Administration will allow a second booster dose (the fourth dose) for all adults, as the agency will hold an advisory committee meeting next month to discuss the topic.
