SARS-CoV-19 antibodies only last six weeks, so you will have to get vaccinated every six weeks.

No reputable source has said that you 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-19 antibodies stay in your body for at least six months, even if you just 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 is saying that SARS-CoV-19 antibodies last for only six weeks.

Vaccinations work by triggering an immune response in the body, and teaching your body how to make the relevant antibodies. In the case of COVID-19, much like with natural immunity, it not clear how long the 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.” As with natural immunity, no reputable source says that you will have to get 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 Organisation or your national healthcare authority.
