Can someone please explain to me the extraordinary negative attitude some people seem to have to the Covid-19 vaccine? Some people seem to think it's some kind of conspiracy to implant microchips into us, others seem to think it has no chance of working. There's a really cynical attitude some people have. Surely the way we beat other diseases like Polio, Smallpox, Chickenpox, Diptheria etc was with vaccines? Why should this be any different?
