French Study Says Pfizer-Biontech Vaccine Less Effective against Indian Variant

A study by France's Pasteur Institute found people who had received two doses of Pfizer saw a three-fold reduction in their antibodies against the B. 1.617 variant.

The Pfizer vaccine is slightly less effective but appears to still protect against the more transmissible Covid-19 variant first identified in India, according to a study by France's Pasteur Institute.
