The Pfizer vaccine is slightly less effective but appears to still protect against the more transmissible Indian strain of the virus that causes Covid-19, according to a study by France's Pasteur Institute. Sixteen of them had received two doses of the Pfizer vaccine, while 12 had received one dose of the AstraZeneca vaccine. People who had received two doses of Pfizer saw a three-fold reduction in their antibodies against the Indian variant, B.1.617, according to the study, but were still protected. "The situation was different with the AstraZeneca vaccine, which induced particularly low levels of antibodies neutralising" the Indian variant, the study said. The study shows that "this variant.. has acquired partial resistance to antibodies," Schwartz said.
