The US authorizes the third dose of Covid vaccine for these categories of people
The FDA has authorized the urgent use of a booster dose of the Pfizer vaccine in people 65 and older, as the most vulnerable and high-risk category for serious illness.
"After taking into account all the available scientific evidence and the discussions of our advisory committee of independent external experts, we decided to allow a booster dose in certain populations such as healthcare, teachers and day care staff, food workers and those of shelters or prisons, "said acting FDA Commissioner Dr. Janet Woodcock in a statement.
Vaccine advisors at the agency unanimously recommended authorizing urgent use of a booster dose of the Pfizer vaccine for people 65 and older and those at risk of serious illness, six months after receiving the first two doses.
"The FDA considered the committee's contribution and made its full review of the data submitted to reach today's decision," an FDA official said in a statement.
Adding that "We will continue to analyze the data submitted to the FDA regarding the use of booster doses of COVID-19 vaccines and will make further case-by-case decisions based on the data."
Bio-pharmaceutical company Pfizer has sought FDA approval to give its vaccine to anyone aged 16 and over, six months after they are fully immunized with two injections.
Pfizer had argued that there was enough evidence to show that immunity begins to weaken after six months and that giving a booster restores immunity safely.
