My wife has had the Moderna (along with all her co-workers and all the seniors in their retirement facility (independent living/retirement community).....maybe 250 people between employees and seniors (and I believe all the other homes in their national network has received the vaccine with no issues - they're one of the large national companies in the retirement plus LTC homes business so thousands of employees and seniors), my friend's senior parent's and brother have had the Pfizer shots, and some doctors/healthcare workers in our family, with no issues. I would personally be fine with either Moderna or Pfizer. I'd be hesitant about Astra Zeneca given the related news but that said, I'm not in any high risk/co-morbidity groups so push come to shove I'd probably be fine with it although preference is with the first two.
