Warm transfer from (Name withheld) from US Covax Support (CEP name documented as provided by, and confirmed with, transfer agent), CEP 159558, with a caller who got the first vaccine and after it, experienced a rash, bumps all over arm, and so he was concerned, went to doctor, and his doctor advised to not get second vaccine, but doctor also said to check with Pfizer to see if it's something he would need to do or not. Product confirmed as Pfizer COVID vaccine by transfer agent. Caller confirmed details, clarifies the rash was bumps, after the initial vaccine, only on arms and legs, not anything more, he heard of other people who had it all over his body, but his was only on his arms and legs, and he works for the (withheld) office, they are having outbreaks again, and the (withheld) doesn't want to mandate to get the vaccine, but caller talked to his doctor and pharmacist and they say they wouldn't get the second dose because he had a rash on the first one, he has no other symptoms, he doesn't feel bad, no one in his house has COVID. He may have put this off for too long, the (withheld) is putting out emails wanting people vaccinated, but is not wanting to force it, and caller wants to do the right thing, caller wants some assurance, he trusts his doctor, has had no issues, when he got the shot, because he is a first responder, he got it as soon as came out, he got it. Rash: started the day after he received the shot, he thought it was ant bites on arms and legs, he is in (withheld) and they have red ants, if you mow in the grass, you can get tore up, but he didn't have a rash on face, or chest, and he talked to other deputies who have spouses, relatives, who broke out everywhere, he didn't but his was noticeable. Rash outcome: after probably about 3 days or 4 days, its gone, he has recovered completely, he feels 100%, feels good, but if he is questioned at work, he wants to make sure he has covered all his boxes and can say he did this and this, and spoke to his doctor, called Pfizer, what more do they want him to do?. he watched it and got with his doctor and his doctor said he wouldn't get the second shot, basically, and to contact Pfizer, and because the numbers are going up, according to whatever news channel watched, the sheriff put something out that people not vaccinated seem to be spreading to others in the agency, so caller was going to go to a grocery store to get the vaccine and a pharmacist asked, he explained everything to her, but all they did was Moderna and Johnson and Johnson, and she said he would have to get Pfizer if he decided to get it. Wife got the vaccine, both Pfizer shots and was fine. Declined report for other people he mentioned (that he talked to other deputies who have spouses, relatives, who broke out everywhere).
