Is the Pfizer vaccine effective against the Gamma variant of coronavirus? As the variant contains the potential immune escape mutation, it has shown to be relatively resistant to the Moderna and Pfizer vaccine.However, the magnitude of the resistance is said to be modest. Madhi et al. While research suggests that COVID-19 vaccines are slightly less effective against the variants, the vaccines still appear to provide protection against severe COVID-19. .

Roll-out Timeline of Select Frontrunners. Of the 10,262 COVID-19 vaccine breakthrough . In a new study using variant virus recovered from one of the original travelers, researchers in the U.S. and Japan have found that vaccination with an mRNA vaccine induces antibody responses that would protect humans from infection with the gamma/P.1 variant. Pfizer and BioNTech said that in the event of a variant which could escape the effects of the vaccines, the firm expects "to be able to develop and produce a tailor-made vaccine against that .
