Following the approval of the Food and Drug Administration, the Centers for Disease Control and Prevention also recommended booster shots for those who are immunocompromised. The news came after Dr. Fauci, the chief medical advisor of the White House declared that Covid booster shots are likely to become necessary in the future.
Dr. Anne Rimoin, an epidemiology professor at the UCLA School of Public Health, agrees with Dr. Fauci: “What’s going to warrant a booster shot is, when we see real, waning effectiveness of this vaccine from keeping people from severe disease and from hospitalization or death. We’re not there yet, but when we are, that’s when we’re going to need a booster.”
The booster shots can be administered for Pfizer and Moderna vaccines and they represent a third dose of the vaccine. Dr. Rimoin explained that the first two doses did not create an immune response that was strong enough to protect those with weakened immune systems.
The booster shots are recommended especially for those who suffer from cancer or HIV, as well as persons who have received a transplant or take drugs that suppress the immune system. It is estimated that around 7 million Americans might need the third dose, which represents 2.7% of all American adults. Compared to healthy persons, for those who are immunocompromised the efficiency of the vaccines dropped from 90% to 72%, going as low as 59% in some cases. Moreover, immunocompromised people are more likely to get severe forms of Covid that lead to hospitalization.
“We think that at least there was a solution here for the very large majority of immunocompromised individuals and we believe that we’ll probably have a solution for the remainder in the not too distant future,” declared the vaccine chief of FDA, Dr. Peter Marks, vaccine chief for the FDA.
