Playing politics with community health is so wrong . Covid is an airborne disease so wearing masks should be common sense but then politicians talk about personal liberty so they can achieve some political gain and win a reelection in their conservative base .They dont care if 635000 people have already died from the disease . Vaccines helps your immune system get ready for the virus in case you get infected . It works only if all the people in a community work together and get herd immunity or the virus will find a weak host and keep mutating and the same people who cultivate the virus will say vaccines dont work . Yeah vaccine will be less efficient everytime it will get a chance to infect a weak immune system and replicate. Duh.
