Pfizer working on booster shot to protect against COVID-19 variants

 Pfizer Inc and partner BioNTech Se are developing booster shots that can protect against COVID-19 variants, Bloomberg News reported on Tuesday, citing Chief Executive Officer Albert Bourla. 

Moderna Inc, whose vaccine has also been authorized for emergency use in the United States, had said on Monday it would test a new booster shot aimed at the South African variant of the coronavirus after concluding the antibody response could be diminished.

Pfizer did not immediately respond to a Reuters request for comment.
