Got 1st dose of Moderna a few weeks back,2nd is due this coming week. Arm was sore for about 2 days, felt a little tired but not much else. Still went to work and gym after vaccine and no issues thankfully. From the research i've read on Moderna one has a 52% efficacy within 1-2 weeks,92% after those two weeks, and 94.1 after the 2nd and final shot. Due to my line of work i was fortunate enough to get the vaccine already and would of taken whatever was offered.
Being a novel virus we really dont know how we'll react, sure you can read the studies of mild effects and people saying it was like the flu. Then you see others whom the virus attacks heart, lungs, kidneys, liver,,it can be quite a nasty little bastard. The smart money is on the vaccine, whether you've had Covid or not. I for one dont wanna be lying in the hospital or on my deathbed haunted by the fact i had the opportunity to protect myself against this and didn't act on it. It's peace of mind for this hobby and going out in public in general IMHO.
