SARS-CoV-2 antibodies only last six weeks, so you will have to get vaccinated every six weeks.

You do not have to get the COVID-19 vaccination every six weeks.

Your body develops antibodies one to three weeks after a COVID-19 infection. The more antibodies you have, the lower your chance of reinfection is. A recent Oxford study has shown that SARS-CoV-2 antibodies stay in your body for at least six months, even if you experience mild or asymptomatic COVID-19. The New York Times has also reported on a separate study that suggests immunity to COVID-19 might last much longer than that, possibly even years. However, another study from Imperial College London says immunity from a natural infection will only last a couple of months. Basically, there is conflicting evidence on how long immunity after natural infection lasts, but no one says that SARS-CoV-2 antibodies last for only six weeks.

Vaccinations work by triggering an immune response and teaching your body how to make the relevant antibodies. In the case of COVID-19, much like with natural immunity, it is not clear how long immunity will last. The World Health Organization (WHO) says that it’s too early to know if COVID-19 vaccines will provide long-term protection because additional research is needed. However, they go on to say that, “it’s encouraging that available data suggest that most people who recover from COVID-19 develop an immune response that provides at least some period of protection against reinfection.” No reputable source has said that you need to be vaccinated every six weeks.

The COVID-19 pandemic has given rise to a lot of potentially dangerous misinformation. For reliable advice on COVID-19, including symptoms, prevention, and available treatment, please refer to the World Health Organization or your national healthcare authority.
