A study published in the journal The Lancet Microbe The acquired immunity after natural infection with the Corona virus is short-lived, and failure to vaccinate those recovering from the virus can increase the risk of infection again with the Corona virus, according to a report on the website. time now news.
Re-infection can reasonably occur within three months or less, said lead author Jeffrey Townsend, professor of biostatistics at the Yale School of Public Health. Too little long-term protection against subsequent infection.”
The team analyzed known re-infection data and immunologic data from viral relatives of MERS-CoV, which cause the common cold, along with immunologic data from SARS-CoV-1 And MERS-CoV By taking advantage of evolutionary principles, the team was able to model the risks of re-infection with MERS-CoV and over time re-infection can occur, even shortly after recovery and will become increasingly common as immunity wanes and new variants of MERS emerge.
“Our study cautions that we should focus more on the risk of re-infection over time,” said Alex Dornberg, associate professor of bioinformatics and genomics at Northwestern University.
He added: “As new variants emerge, previous immune responses become less effective in combating the virus and it is increasingly likely that re-infection in the near future to those who were naturally infected early in the epidemic.”
The team’s data-driven model reveals striking similarities with the risk of re-infection over time between corona and endemic coronaviruses. “Just like the common cold, you may catch the virus again from year to year,” Townsend said.
“Given the ability of the coronavirus to evolve and re-infect, it is also likely to move from pandemic to endemic,” Dornberg added.
