Some people don’t want to be vaccinated for the time being but would instead rather wait for an inactivated vaccine to be approved. This is not expected to be the case until the first quarter of 2022 at the earliest. However, no one should be unprotected through the winter because the risk of being infected and suffering from severe symptoms is too high. Furthermore, the risk of intolerance cannot be ruled out even for inactivated vaccines.

So let’s discuss the two types vaccine that are currently approved: Vector and mRNA vaccines. As soon as the body comes into contact with coronavirus, both types of vaccine remember the protective response and are highly likely to prevent infection. 

Viral vector vaccines

Viral vectors function as antigens in these vaccines. Viral vectors are harmless to humans. They carry tiny, harmless pieces of the pathogen into the body. Your immune system then responds with a protective reaction.

Viral vector vaccines include the vaccines produced by AstraZeneca and Johnson & Johnson.

 

mRNA vaccines

The mRNA vaccine contains mRNA, on which a set of “building instructions” for antigens is stored. This enables the human cells to make their own antigens. These antigens are harmless. They ensure that the immune system works and that a protective reaction is triggered.

Examples of mRNA vaccines are the products of BioNTech/Pfizer and Moderna.
