The Czech Ministry of Health along with specialists in the field declared that solely the presence of antibodies in one’s circulatory system cannot be considered as a reliable indicator of protection from covid-19 just yet. Thus, any level of antibodies will not be accepted as a replacement of vaccination. There are two main reasons for the verdict. Firstly, the exact amount of antibodies that can prevent a human organism from getting infected by covid-19 is still unknown. Secondly, various covid variants have appeared and it is uncertain, whether a person with Alpha variant antibodies will be immune to the Delta variant. Consequently, the government urges us to wait for further observations and get vaccinated in the meantime.
