Islam News – Pfizer and its partner BioNTech released early results from studies of people who received a booster dose of their mRNA vaccine, and said that “a third dose may be needed within 6 to 12 months after full vaccination.”

 

However, many scientists were critical of the announcement, pointing to evidence that the current two-dose regimen is powerfully effective against the coronavirus. “We are prepared for booster doses if and when the science demonstrates that they are needed,” the F.D.A. and the C.D.C. said in a joint statement, according to The New York Times.

 

Some experts also questioned the need for boosters for Americans while much the world has yet to receive even a single dose. Every unvaccinated person offers the virus additional opportunities to mutate.

 

“If we’re worried about variants,” said Dr. Céline Gounder, an infectious disease specialist at Bellevue Hospital Center in New York, “our best protection is to get the rest of the world vaccinated, not to hoard more doses to give third doses of mRNA vaccines to people here in the U.S.”

 

Pfizer also announced a plan to begin clinical trials of a new version of its vaccine to specifically target the Delta variant, as a sort of backup effort in case the boosters of the original vaccine should falter.
