Got my second Moderna from Walgreens. First shot just gave me a mildly sore arm at the injection site. Second shot brought with it in addition some next-day flu-ish symptoms (nausea, overall achey-ness, feeling of slight fever) which lasted 4-5 hours (roughly 10 am to 3 pm), then gradually subsided. Day after that just a touch of nausea. Today feel fine.
