A new study from England suggests that immunity to COVID-19 disappears over time, meaning you can always get infected again.
Even if you get a COVID-19 vaccine, you still have to protect yourself. A new study suggests that COVID-19 immunity wears off over time. However, the study looked at just one measure.
CNN reports that the study involved hundreds of thousands of people in England. For the research, the team sent out home finger-prick tests to 365,000 people in England. The researchers chose subjects randomly. After gathering the test results, the team found a decline of over 26% in COVID-19 antibodies after three months.
The team said that these results reaffirm previous evidence. Earlier studies have shown that COVID-19 antibodies decrease over time. The body makes antibodies to fight infections.
Initially, the study reported that 6% of the people who took the home tests had COVID-19 antibodies. However, by September, the number dropped to 4%. The rates were the same for healthcare workers.
Young people who recovered from COVID-19 experienced a slower antibody loss. People over 75 years old lost antibodies faster.
However, experts still don’t know if antibodies grant total immunity against COVID-19. They also don’t know how long you stay immune after getting sick again.
What the Study Means
Despite the results, the study is still encouraging. The results show that COVID-19 acts like other colds. Antibodies to colds disappear over time, too. So, if you get a cold once, you can always get it again.
The results show that experts can predict COVID-19. People can also take better care of themselves after knowing these results. After all, just because you survived COVID-19 once doesn’t mean you can’t get it again.
