According to a recent study published in the Journal Nature on Monday by researchers from the United States and Switzerland, “The observation that memory B-cell responses do not decline after 6.2 months, but continue to evolve, strongly suggests that people infected with SARS-CoV-2 could generate a rapid and effective response to the virus after re-exposure. “
The study looked at dozens of recovered COVID patients and noted that while their antibodies may decline over time, they maintained levels of specific memory B cells, which play an important role in defending the virus. 87 people participated in the research and it was found that while the antibodies decreased over a period of one month to 6 months, they remained the same.
Another study published in the journal Science this month suggested that most parts of the immune system, including specific memory B cells with protein spikes, could identify and continue to respond to the virus for at least eight months.
