You and your great-grandfather or grandmother, do you remember them? It doesn't matter, what matters is how many infectious diseases were dangerous in their time and they may have been infected but you did not? That is the impact of vaccination.
I'm a dental student, and from my position, I realize how important vaccinations are.
Our professors constantly tell us about dentists getting infected by their patients or vice versa as a result of not having the necessary vaccinations. Please help us and help yourself before to get community immunity.
I know that there are a large number of vaccines you can get, but each person can start by getting the recommended vaccines for the most common diseases in your surroundings.
