Most of your reply isn’t really correct.

> A vaccine is also an attenuated version of the virus so if becoming immune from the virus doesn't last long it won't last long from a vaccine.

A vaccine can be an attenuated virus, or a piece of mRNA or DNA, or a distinctive viral protein. Which type of vaccine you use+the adjuvants that go with it can result in very different immune responses and efficacy over time.

> This is false, immunity is strong and long-lasting.

Immunity to COVID-19 varies a lot person to person and is poorly understood. It does however appear that many people can be reinfected (especially people who had mild symptoms the first time.)

Most of your reply to my reply is incorrect.

>mRNA is part of a pathway that creates a protein that is on the virus which the immune system reacts to.

>Please post your source saying that people can be re-infected.

The only reason people are testing positive again after having Covid and healing from it is because the test is very poor at distinguishing between various coronaviruses, the vast majority of which are harmless and sometimes cause the common cold. There is a big false positive rate as a result.

Could you link to studies that support this point of view, if you have any? What are your sources?
