A 26-years-old male patient received first dose of BNT162B2 (PFIZER-BIONTEC COVID-19 mRNA VACCINE, Solution for injection, lot number: ER8732 and expiry date was not reported), via an unspecified route of administration, in Arm Left, on 15Apr2021 at 09:00 (age at vaccination: 26 years), as a single dose for COVID-19 immunization at Church. Vaccine was not administered at       Facility. The patient's medical history included autism spectrum disorder, orthopedic issues, and latex allergy. Concomitant medications were not reported. The patient did not receive any vaccine prior vaccinations (within 4 weeks). It was reported that the following morning after getting his first dose he experienced swelling entire body and lip area/swelling to entire body; swelling of his arm, face, lip, possible tongue swelling and lip area that looks like you could see his pores on 16Apr2021. The patient took benadryl. The reporter asked who they should contact as she wanted to schedule her children's second dose at a hospital or a vaccination site where there were doctors and ambulance. If ever they will experience worse side effect from the second dose, they could be rushed to the hospital or there would be an ambulance waiting. He experienced swelling to his entire body. In his lip area, he was so swollen you could see his pores. However, her son did not communicate verbally things well. She kept asking about the tenderness in her sons arm at the site, but he was saying nothing. Caller explains by her son saying nothing, it means that something bothers him, he just did not want to say what it was, he could not articulate it. She clarified she could see the swelling on his arm and face, but his eyes did not swell shut. There was significant swelling that she could see on his body. He was taking his tongue and rolling it over his teeth and mouth, so she assumes her son probably experienced tongue swelling as well. She explained her son's symptoms started into the night like it did with her daughter. Her son was up until midnight and she was asking him periodically throughout the day "were you feeling anything". She looked at him throughout the day of receiving the vaccine and he was not complaining of anything or any itching. He looked fine. He never did say anything, however, the caller could just see the swelling on her son. Her son had incontinent issues as well, but he had no diarrhea or any-thing. She clarified her had a bed wetting incident. He was drenched. Normally, if her son wets himself, the minute he feels it, he will wake up and let the re-porter know. However, with this incidence, he did not. By the time he woke wake up, he drenched his entire bed as well as his comforter, which was not like her son. Reporter discovered this incident between 07:00-08:00 the following day of receiving the vaccine. Reporter gave her son Benadryl for about 4 straight days. He did not seem to look as swollen, she did not see any rashes. However, she did saw see little bumps on his body. Her son was total care- they have to totally toilet, bathe and cleanse him. She did not see notice any rash on his body after about 4 days, so she stopped his Benadryl after day 4. Before her children got their injections, the reporter asked was anything that they were doing have latex because all of her children have latex allergies as well. The re-porter was informed there was no latex was used at the vaccination site. The adverse events did not require a visit to emergency room and physician office. Outcome of the events bumps on his body and incontinence; bed wetting incident was unknown and for all other events, it was recovered on 20Apr2021.  No follow-up attempts are needed. No further information is expected.
