The researchers from Beth  Israel Deaconess Medical Center (BIDMC) found in a study that new  variants that emerge may be more transmissible and may more effectively  bypass the immune protection from prior infection or vaccination.

A new study by Beth Israel Deaconess Medical Center (BIDMC) in Israel, published in the New England Journal of Medicine,

found that the newer Omicron sub variants of coronavirus substantially  escape neutralising antibodies induced by both vaccination and previous  infection.

What The Study Found? The researchers from BIDMC evaluated antibody response to multiple  SARS-CoV-2 Omicron subvariants in 27 vaccinated and boosted individuals  and 27 individuals who had previously contracted COVID-19.

What The Study Found? It was found that three Omicron subvariants– BA.2.12.1, BA.4, and BA.5–  substantially escape neutralising antibodies induced by both vaccination  and previous infection.

What The Study Found? As per the study, the neutralising antibody responses to BA.4 and BA.5  were approximately 20-fold lower than to the original WA1/2020 strain  and were 3-fold lower than to the Omicron BA.1 and BA.2 variants.

What Did Researchers Conclude? According to the researches, the study provided the immunologic context  for current surges among populations with high rates of vaccinations and  previous infection.

“Our findings suggest that the Omicron variants have continued to  evolve,” said study senior author Dan H Barouch, director of the Center  for Vaccine and Virology Research at BIDMC.

“This has important public health implications and provides the  immunologic context for current surges among populations with high rates  of vaccinations and previous infection,” Barouch added.
