You can be immune to COVID for so long, the study suggests


Since the onset of the epidemic, researchers have been trying to determine how long COVID-19 Immunity persists. While it has become clear that re-infection is possible, they are also hoping to understand the possible severity of the second or third infection. Two new studies published this week hope to answer all questions surrounding COVID-19 immunity. Read on to find out how long immunity lasts after COVID — and to ensure your health and the health of others, don’t miss it Sure sign you had COVID and it’s still messing with you.

Immunity can last a full year — maybe even a lifetime

According to a study published on Monday in the journal Nature, Immunity lasts for at least a year – perhaps even a lifetime – and continues to improve over time. Later immunity also becomes stronger. Vaccination.

Therefore, and keep in mind that this is not yet conclusive, if you had COVID-19 – even a mild case – and then fully vaccinated, you may not need a booster. Alternatively, if you have never had COVID, but have been fully vaccinated, you may need a booster.

Senior author Ali Allebedy, PhD, a colleague, “Last fall, there were reports that antibodies decrease quickly after infection with the virus that causes COVID-19, and mainstream media interpreted that That immunity did not survive long. ” Professor of Pathology and Immunology, of Medicine and of Molecular Microbiology, explained in a Press release.

“But this is a misinterpretation of the data. It is normal for antibodies levels to go down after acute infection, but they do not go below zero; they plateau. Here, we have 11 months after the first symptoms in people with antibody- Productive cells were found. These cells will live for the lives of the remaining people and produce antibodies. This is strong evidence for long-lasting immunity. “

He also explained that people with mild cases clear it off their bodies two to three weeks after the infection, “so there will be no virus that drives an active immune response seven or 11 months after the infection,” he reported. “These cells are not dividing. They are silent, just sitting in the bone marrow and secreting antibodies. They have been doing this ever since the infection has resolved, and they do so indefinitely. will continue.”

According to their research, even those who were infected but remained asymptomatic can be left with long-lasting immunity. “But it remains to be investigated whether those tolerating more serious infections will be protected from future disease.”
