As I understand it Covid 19 is not just going away. I am not a medical professional so I cannot speak to how it works. I do know that it is very contagious and that we must take preventative measures to protect ourselves. Taking the vaccines and boosters is one good way to protect ourselves. It may not keep us from catching it but supposedly the vaccine and boosters will greatly minimize how severe the symptoms will be. Wearing a mask when around large groups of people might be another way to minimize risk.
