Not how vaccines work. You create antibodies as a part of your adaptive immune system by B cells in response to antigens. Vaccines are an identical copy to this method. They introduce an antigen and your body recognizes it and builds up immunity.
There is nothing in this processes that modifies the immune system.
I know how vaccines works, like the Russian vaccine was an extract from the Adenovirus, it was a successful test, but for now. But, humans will only deceive themselves, the real part they need to focus on, they did not. Prevention is always better than cure. Why the world is not focusing on the people in a way all will be employed to get the kind of life they want, so that they can leave a healthy life they want, healthy life style is a way to improving us. We are going more into bioengineering. No matter what humans do, it can not be like natural ones. Education, safety measures and healthy lifestyles can help against this virus. Not that I really against the vaccines, but the world need to wake up and see their ignorant parts.
