Immunity to Covid-19 could disappear only a few weeks after taking the virus.


According to the study, patients who tested positive for the virus saw a decrease in the amount of Covid antibodies in the weeks and months following infection.

New research suggests that immunity to Covid-19 may disappear within weeks of infection.

The antibodies in coronavirus patients decreased significantly in positive patients, experts say

During this period, the percentage of individuals testing positive for Covid-19 antibodies decreased by 26.5%, indicating that antibodies decrease in the weeks or months following infection.

More than 365,000 randomly selected adults tested themselves at home with a finger prick test between June 20 and September 28 to see if they had antibodies to Covid-19.

Research from Imperial College London and Ipsos MORI suggests that our immunity to the virus – which currently affects countries around the world – is decreasing over time.

Even people over the age of 75 lose their antibodies faster than people aged 18-24.

It has also been found that people who did not have symptoms while infected with the virus are more likely to lose Covid antibodies.

This means that if you were asymptomatic, you would be more likely to be infected with the virus a second time.

said Health Secretary Lord Bethell: “This study, led by Imperial and Ipsos MORI, is an important research project that will help us understand the nature of Covid 19 antibodies over time and improve our understanding of the virus itself.

“We rely on this type of important research to inform us about our further response to the disease so that we can continue to take the right actions at the right time.

“It is also important that everyone knows what this means for them – this study will help us in our fight against the virus, but a positive test for antibodies does not mean you are immune to Covid-19.

“Regardless of the result of an antibody test, everyone must continue to follow government guidelines, including social distancing, self-isolation and conducting a test when you have symptoms and always remember hands, face, space”.

Professor Paul Elliott, Director of the REACT program at Imperial from the School of Public Health, said: “Our study shows that over time, the proportion of people testing positive for antibodies to the virus causing Covid-19 decreases.

“It remains unclear what level of immunity antibodies provide or how long this immunity lasts.

“If someone tests positive for antibodies, they still have to follow national guidelines, including social distancing measures, performing a swab test when they have symptoms, and wearing face protection when necessary”.
