According to a recent study published in the Journal of Nature on Monday by researchers in the United States and Switzerland, “B cell memory responses are not expected to decay after 6.2 months, but instead growing up, strongly suggesting that infected individuals. SARS-CoV-2 may provide a rapid and effective response to the virus upon re-exposure. “
The study looked at dozens of patients recovered with COVID and found that while their antibodies may decrease over time, they maintained levels of specific B memory cells, which have plays an important role in keeping out the virus. 87 people took part in the study and it was found that although the antibodies decreased over one month to 6 months, they remained the same.
Another study published in the journal Science this month suggested that most of the immune system, including protein spike B memory cells, can recognize and continue to respond to the virus for at least eight months.
