In individuals vaccinated with two doses of vaccine, Pfizer antibodies/ BioNTech present in the blood serum are effective against the British strain of the virus, but they are slightly less effective with the Indian type, according to research findings.
“Although efficiency has decreased slightly, according to laboratory tests, Pfizer vaccine is credible that it protects”, said Olivier Schwarz, coauthor of research and director of the Department for Virus and Immmunity at the Clean Institute in Paris.
Researchers also tested the effectiveness of AstraZeneca vaccine in those species, but only in people vaccinated with a dose of vaccine, since they currently have no access to samples with two doses.
Since the second dose of this vaccine is given in 12 weeks, and preparation began to be used in the EU in February alone, other doses began to be delivered only at the end of April in France, and in a smaller number of people, since it is limited to grant the population over 55 years old.
Based on one dose, the results show that AstraZeneca vaccine, which is effective for the English strain of the virus, has very little effect on India and South Africa.
A dose of the vaccine seems to have little or no effect on the Indian type, researchers said.
Indian variation (B.1.617) was discovered in India in October 2020 and has since spread to a number of other countries, including Great Britain.
