The corona vaccine, like the flu shots, is likely to be given every year
A White House official said Thursday that the United States was preparing to give people a third dose of the vaccine within nine to 12 months of receiving the coronavirus.
David Kessler, chief science officer of US President Joe Biden’s Corona Virus Response Task Force, testified before a congressional committee that scientists are currently examining how long after receiving the full dose of the vaccine. Immunity will remain to fight and when more doses of vaccine may be needed.
“At the moment, it is thought that people who have a weakened immune system against the coronavirus due to a physical illness will be given the dose first,” he said.
On the other hand, the broadcaster CNBC has reported that Pfizer’s chief executive officer Albert Borla has said that it is likely that people will be given a third dose of the vaccine within 12 months.
According to preliminary data, Pfizer and Moderna vaccines are resistant to the virus for at least six months. Research is ongoing into how long this immunity will last.
Experts say that even if the immune system is effective for more than six months, new types of the rapidly spreading coronavirus, and the types that are likely to emerge in the future, should be treated in the form of annual flu shots. A dose of the virus vaccine may also be given.
