I keep reading the CCD website and the CCD website keeps changing as this covid thing is fluid. I'm glad I did not take the vaccine that the first person who posted here did. It did not work as originally intended. I am glad that so many did take this risk for me and are allowing me to see the side effects via their experience. Full Discloser I refuse the flu shot as well. I haven't been sick since I was 22, I'm am 43 now.
