Covid fourth wave: A new study by the Beth Israel Decons Medical Center (BIDMC) in Israel, published in the New England Journal of Medicine, found that new omicron subtypes of coronavirus survive significantly in neutralizing antibodies induced by both vaccination and previous infections.

What did the study find?
- Researchers at BIDMC evaluated the antibody response to multiple SARS-CoV-2 omicron subvariants in 27 vaccinated and stimulated individuals and 27 individuals previously infected with Covid-19.
- It was found that three omicron submarines B BA.2.12.1, BA.4, and BA.5 નોંધપાત્ર survived significantly in neutralizing antibodies induced by both vaccination and previous infections.
- According to the study, the neutral antibody responses to BA.4 and BA.5 were about 20-times lower than the original WA1 / 2020 strain and 3-times lower than the Omicron BA.1 and BA.2 variants.
What did the researchers conclude?
According to the research, the study provided an immunologic context for the high rates of vaccination and the current increase in populations with previous infections. “Our findings suggest that omicron types are constantly evolving,” said Dan H. Broch, senior author of the study, director of the Vaccine and Virology Research Center at BIDMC.

“These have significant public health effects and provide an immunological context for vaccinations and the current increase in populations with high rates of previous infections,” Broch added.
Recap: Since the initial highly contagious SARS-CoV-2 omicron variant of SARS-CoV-2 – known as BA.1 – emerged last year, its new subvariants are constantly evolving. Researchers at BIDMC noted that the new strains that emerge may be more contagious and may more effectively bypass immune defenses than previous infections or vaccinations.
