I hope you are feeling better now. I didn't get the vaccine, but I have been taking elderberry syrup which I make myself. Elderberries will be ready to pick soon too. I'm in UK and a hospital did a trial on using elderberry syrup and they said it worked. Best thing about it is that you can make litres of it practically for free, or you can buy over the counter.
My ex had two vaccines. After the first he rushed to hospital with kidney problems. This was a couple of weeks later. After the second he was unusually signed of work for a month. He is usually fit as a fiddle. I take hemp oil for seizures so I gave him a bottle as it helps relieve pain. He told me he was able to walk again several hours after taking the hemp/CBD oil. It might be worth looking into the 'Endocannabinoid system' to learn about how and why CBD helps with seizures, cancer, pain etc. You might decide to get some hemp oil.
