The caller is calling about the covid vaccination with the 2 shots and the first booster. The caller is strictly a Pfizer person. The caller has not reported this to VAERS, he has talked with them and asked them a bunch of questions. The VAERS agent said anything the caller tells Pfizer would be reported to the CDC for his side effects. If the caller reports it to VAERS they wouldn't communicate it with Pfizer. The symptoms the caller had after his first dose all occurred over 7 days. The caller's symptoms started with left arm, where he got the shot, general aches in the joints muscles which decreased over 2-4 days. This event's onset started 2 days after he got the first dose with was on 01Apr2021. This symptom was still there but it decreased, this was the first wave. Chills and fever. This started 3-5 days after the first dose and it decreased. The caller's fever was 98.5 degrees which is a lot because he is normally in the lower below 97 degree range or around there. The caller tries to keep up with everything and the WHO said we are half way through the pandemic which means another 2 years.

The evening of the 6th day after the first dose the caller got up at night to go to the bathroom and didn't think anything of it. The caller urinated the following morning there is rose coloured orange in his urine. the caller is not prone to that. This has never happened to the caller before. It hasn't happened since that shocking incident which freaked the caller out. All during the first week of symptoms the caller's appetite was good but he lost about 5 pounds and was eating all the time. This is even a little extreme for the caller because he has this thing going with water. The caller usually fluctuates 2 to 3 pounds daily. After the second dose the caller had the following symptoms that all ran together over 2 days. The caller didn't have any really big side effects after the third shot, the booster. After the third dose both armpits itched and the caller knows that could be because there are lymph nodes and some of the shot goes to there. The caller's calves itched, he doesn't know if this was a coincidence or not. The caller didn't know if his deodorant was doing this so he stopped using it and it didn't really help. It was another 2-3 days of intense itching lessening over a month. When the caller was 5 or 6, in 1961 or 1962. The caller was involved in the original Polio vaccine in (withheld) county there was a polio outbreak and he remembers standing with his neighbours getting a booster for Polio.
