The severity and lethality of the COVID-19 pandemic, which we still cannot bring to an end, has been brought under control thanks to the vaccines released so far. However, previous vaccines need to be developed in order to find a vaccine that provides all or at least long-term protection when taken. So until that happens, we have to be concerned with how strong and how long-lasting protection current vaccines provide.
In the past weeks, the BioNTech vaccine had received a third dose approval from the FDA and EMA, as it lost its protection after 6 months. We learned months ago that Sinovac loses its effect after the third month. There is not enough data yet on which vaccine would be better for those who have 2 doses of Sinovac vaccine, but if we are satisfied with the data we have, BioNTech is the answer.
Protection goes up to almost 100% with BioNTech
Allergy Immunology and Chest Diseases Specialist Prof. Dr. Ali Kutlu shared on Twitter which vaccine would make more sense to have 2 doses of Sinovac. Stating that there is not much data on this subject, Kutlu presented a table prepared according to the data obtained in Chile to people who have question marks on this subject. According to the data, getting the Sinovac vaccine again after 2 doses of Sinovac increases the antibody rate from 54% to 74%, while the 3rd dose of BioNTech vaccine increases this rate to 95%.
Whether it will be the 3rd and maybe even the 4th dose, or even more than this, is one of the most curious topics in the pandemic field at the moment. As we mentioned at the beginning, the long-term protection of a vaccine also depends on the updates it will receive after its release. One of the founding partners of BioNTech, Prof. Dr. Uğur Şahin had previously announced that the formula of the vaccine would change. It is a mystery when there will be a time when this dose of talk will no longer be needed.
