There's hardly a "medical reason" on earth why anyone shouldn't have the vaccine. The percentage of people needed to be immune (via vaccine or catching the virus) needs to be in the high eighties or low nineties in order for us to get to herd immunity. Antivaxxers and namby-pamby vaccine-refusers (who love to proclaim their ignorance from the rooftops: we've had at least one on here who sarcastically thanked the rest of us for being his guinea-pigs before he decides whether, down the line, he should take the vaccine) will seriously hamper efforts to get the virus under control, and more people will suffer and die. The side effects are either slight and transient or non-existent and all the vaccines are safe and effective. Even the Queen was rolled out to tell us that (and good for her, say I). I'm having mine on Sunday and bloody wild horses wouldn't stop me.
