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