and means the T cell branch of the immune system stops responding to a virus and no longer kills infected cells,” says Peluso, assistant professor in the UCSF Department of Medicine and co-first author. “This finding fits with some hypotheses that long COVID, or at least some cases of...
Everyone's immune system is slightly unique, and SARS-CoV-2 continues to mutate, so knowing exactly how long COVID immunity lasts is complicated. Evidence suggests immunity followinginfectionshould generally last six months inhealthy adults, and can be prolonged with vaccination. But there are excep...
Other factors also increase your vulnerability to reinfection, starting with how long it has been since you had Covid. Immune defenses tend to wane after an infection. A study published in October 2021 estimated that reinfection could occur as soon as 3 months after contracting Covid-19. While...

How long does COVID last if I'm vaccinated? It's unclear if the vaccine lowers the duration of COVID symptoms because everyone's immune system reacts differently to infection. But the vaccine can lower your risk of serious infection, hospitalization, or death from COVID. ...
The researchers will continue to follow the participants for three years to document how the immune system continues to respond long term. The 'COVID-19 SA' study results have been published on a preprint server ahead of peer review—"Long-term perturbation of the peripheral immune system months...
Can you become immune to COVID-19? Patients who recover from COVID-19 make antibodies to the virus that may impart immunity for at least 6 months; however, breakthrough infections do occur and may be more likely with newly circulating variants of the virus. Immunizing with the latest ...
Genetics also plays a role in how severely people get sick. Some people have mutations in the innate immune system, which is like the first responder part of your immune system and is pretty generic. More specific re...
T cells can identify and target SARS-CoV-2, but how long does the immune reaction last, and might some people’s responses go into overdrive?Credit: selvanegra/ Getty Images Disclaimer: This is a fast moving field. Information is up to date at time of publishing ...
immune status of the infected populations at a given time point. The key point has been that, even with vaccination and milder presentations of acute infection across recent variant waves, the cumulative burden of long COVID has continued to rise (Fig.1). Progressing from long COVID cases of...
