Pfizer Coronavirus Vaccine less effective but effective at new strains: Study


Paris
A study in France has revealed that Pfizer The corona vaccine is less effective but is able to protect against corona strains spread in India. The Pasteur Institute of France has done this study. Olivier Schwartz, director of the institute and co-author of the study, said, “Despite slightly lower efficacy, the Pfizer vaccine protects against variants found in India.”

For this study, 28 health workers from the city of Orleans were sampled. Of these, 16 received two doses of the Pfizer vaccine, while 12
received one dose of the AstraZeneca vaccine. According to the study, people who received two doses of Pfizer showed a threefold decrease in antibodies against the B1.617 variant of Corona, but were still safe.


The study stated, ‘The situation was different with the AstraZeneca vaccine, particularly as it induced low levels of antibodies to neutralize the B1.617 variant.’ Schwartz stated that patients who had Kovid-19 within the past year and who were vaccinated with two doses of Pfizer had sufficient antibodies against the B1.617 variant but three to six times the variant found in the UK Less antibodies were found.

Schwartz stated that the study shows that this variant has acquired partial resistance to antibodies. The SARS-CoV-2 virus has produced several variants of the corona since it first emerged in China in late 2019.
