Fact Check

Do covid vaccines lowers immunity?

The available scientific evidence shows that covid vaccines lower immunity for a short time, but strengthen immunity against covid virus in the long run. Covid vaccines train the immune system to fight against the covid virus. 

Vaccines activate T cells to build a memory against the infection and provide the strongest immunity. However, it takes time for the immune system to create this memory. Hence, immunity lowers immediately for a few days after taking the covid vaccine. 

But once the memory is built, the immune system immediately recognizes the infection and stops people from getting seriously sick.

Did flu exist before covid vaccine?

Yes. Flu existed before the covid pandemic and its vaccine. The U.S. Centers for Disease Control and Prevention website informs that the 1918 influenza pandemic was one of the most severe pandemics. Influenza is caused by the H1N1 virus. The website also informed that the 1918 pandemic affected one-third of the world’s population.
