I don’t think the vaccine itself will worsen a cycle. I do believe other states of inflammation will mitigate how bad a cycle can be. The injections do incite an immune response which is variable between individuals. The second shot seems to bring on more symptoms in people who have reactions. It’s even worse in folks who had the virus and chose to get the vaccine.
I do think its worth considering the vaccine because COVID itself releases such an aggressive immune/inflammatory response it’s bound to exacerbate a cycle or make a chronic more miserable.
