Pfizer Vaccine Less Effective- New Delhi: A study by the French Pasteur Institute found that the Pfizer vaccine was less effective but offered protection against the highly contagious Coronavirus that was first discovered in India. “Without a slight reduction in efficacy, the Pfizer vaccine is likely to protect” the species found in India, according to laboratory test results, “AFP news agency quoted Olivier Schwartz, director of the institute and author of a study published on the BioRxiv website before a review. .
Pfizer Vaccine Less Effective- The study was conducted on 28 health workers in Orleans. Sixteen of them were given two doses of the Pfizer vaccine while the other 12 received a single dose of AstraZeneca COVID-19 vaccine. The study found that “people who received two doses of Pfizer saw a threefold decrease in their antibodies compared to variant-B.1.617”, reports AFP
“The situation was no different with the AstraZeneca vaccine, which created very low levels of antibodies making the difference being B.1.617,” the study said.
In addition, patients who had received Covid-19 last year and were vaccinated against the virus in two doses of Pfizer had sufficient antibodies to stay safe from the high-risk B.1.617 variant in India. However, antibodies were three to six times lower than in the UK range, Schwartz told a news agency.
Pfizer Vaccine Less Effective- The World Health Organization (WHO) states that variants of the B.1.617 COVID-19, first discovered in India, are now commonplace in 53 countries. The WHO had declared B.1.617 a different concern, noting that the transmission and severity of the disease had increased.
