Everyone looks at this vaccine differently and undoubtedly it saved a lot of lives early on. I am closing in on 67, so not far behind you, but I have only had the original 2 shots and then one booster after. Booster was about 18 months ago now and frankly I am not considering any additional covid shots unless this virus rears it's ugly head again and regains strength. Right now Covid is still out there, I guess, but I don't hear much about it and frankly it's not anywhere close to being as potent as it initially was. So no more shots for me unless this changes. Just my viewpoint. I suspect it's your pharmacy (CVS/Walgreens etc) that is sending you those damn messages saying your due again. I ignore their crap messages, as all they care about is getting reimbursed for vaccines, they could care less about our health. I understand that business all too well! But to answer your question, yes, I have now developed osteoarthritis as well since I've had these shots. I will never know if the vaccines had anything to do with it was coming on anyway and timing was just coincidental? Best to you!
