Hello friend, the truth is that this virus has taken us all by surprise and today there is talk about its mutations, it is a difficult situation because as you say it worsens the whole picture and the vaccine that is already established would be useless. I think it is a very difficult situation for the health profession and also people do not do their part, they do not take care of themselves or others, so it is much more difficult to fight any disease. Greetings!
I am very concerned that the development of the vaccine is taken as something commercial.
Many will benefit financially from these vaccines, which will never be fully effective, especially with the new mutations that are occurring in the original strain.
