My dad and a couple brothers have had the first round of the vaccine, with no side effects. My sister has had both, with no side effects -- she's a nurse, so was prioritized. My mother in the UK has had the first shot, but there, from what I understand, they are taking a different aproach: getting everyone the first shot before giving people the second, as opposed to getting groups both shots before moving on to less prioritized groups. There are pros and cons to both approaches, I suppose. I have friends in AZ that have received both with no side effects. I'm eligible in AZ because I continue to teach at a university there, but I'm not taking the chance to travel to get it.
Here in Mexico there is not much information. Front line workers are supposed to be prioritized, but our Dr. hasn't received it yet. Both the president and (former richest man in the world) Carlos Slim have it. We've had friends get sick and lost a few. My former secretary lost her mother and step-father one day, her father the next day (not covid), and a brother the following day. She is also currently sick with C19. We just became the third worst country affected, after the USA and Brazil.
Stay safe, folks.
