Who knows, hopefully never. But in that same 9 week time period i never received a “covid vaccine” and I feel great and don’t have to worry about later bad effects.
My wife works at a nursing home and COVID has been through it twice and several of her co-workers had it. A year and a half later and she/we haven't gotten it. We also haven't gotten the flu or a cold in 4-5 years. She used to bring every bug home and we'd get the flu or a cold 2-3 times a year and then it just stopped. Personally, I feel that we're probably immune to coronaviruses and the flu at this point and don't need the jab. We had a flu shot once 15+ years ago and it made us sicker and for longer than the flu so we never got another one.
