New research released Wednesday suggests Kovid-19 survivors should be concerned about losing their natural immunity to coronovirus soon. The findings suggest that in most people, a strong immune response to the virus lasts for at least eight months – and are Good indications that this may happen last year as well.
There have been concerns about deterioration in immunity since the onset of the epidemic. related Coronavirus that causes normal C.The old are often known to strengthen people, and scattered Kovid-19 news brought out In 2020. Some studies have also suggested that the level of antibodies to the virus may drop substantially. three months.
On the other hand, immunity is a Complicated mess. Antibodies are not the only source of immunity that we find against germs such as coronoviruses. And, So far at least, confirmation of confirmation accounts still appears rare. This new study, Published In science, this provides the most updated information about how our immune response to viruses changes over time and this decision is largely positive.
Scientists studied the blood of 180 volunteers who had confirmed Kovid-19, with samples taken after six months of infection. Antibody levels for the virus took a small dip after infection But remained stable after that Up to eight Months in most people. T cells specific for the virus also declined slightly after three months but remained stable again later. Meanwhile, memory B cells, which help wake the immune system in response to a familiar threat and produce more antibodies when needed, were actually more abundant in six-Mark of the month compared to a month. This is particularly encouraging, as these B cells are important for long-term immunity, the way it lasts for years.
The findings do not directly show that our immunity to Kovid-19 will last exactly eight Months and longer. Scientists are still trying to find out how these immune responses in the body are protected in the real world. But all told, 95% of the people in the study had some level of antibodies, immune levels in B cells, And T cells with five viruses Eight His symptoms started months later. This indicates, the authors wrote, that “durable immunity against secondary Kovid-19 disease is a possibility in most individuals.”
Antibodies are the most important part of immunity to prevent the effects of germs.. This and other research has shown that our antibody levels of coronovirus can vary greatly from person to person. In order to understand why some people have reinvested in such a short time in some cases To be presented After only three months. But as noted by expertsOther remaining aspects of our immunity should generally protect people from more serious illness if they are infected. second time.
All told, the current epidemic situation is still very bad, with daily affairs, hospitals, And deaths in america The recordHigh Levels. I amT will take more time to explore other important questions, Such as how long the vaccine provided immunity will last. But in a sea of bad news, at least something is expected to be overcome.
