A 59-year-old male patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE), second dose via an unspecified route of administration, administered in the right arm on 12Apr2021 at 10:45 (batch/lot number: EW0162) as a single dose for COVID-19 immunization. The patient has no medical history and no concomitant medications. Historical vaccine included BNT162B2 first dose on 15Mar2021 at 11 am (lot number: EM6208) for COVID-19 immunisation and experienced excess mucous (started at the end of Mar2021 or beginning of Apr2021), has fits where he was trying to cough up mucous and allergies. The patient reported that he just got his second Pfizer shot Monday 12Apr2021, and he got his first one 15Mar2021. He wanted to report what he thinks was a side effect. He doesn't know if it was related or not, but at the end of Mar2021 or beginning of Apr2021, he started having excess mucous. He has fits where he was trying to cough up mucous for 45 minutes. Ever since it started there has been a lot of mucous. He has been taking Benadryl and stuff like that. He headed to urgent care Sunday 11Apr2021, but decided to go to the ER instead because he was having a mucous coughing spell. They checked for pneumonia, but it was negative. They were contributing it to allergies, but he has never had them this way before. He wanted to report because he was thinking maybe it was something from having the vaccine. He thinks the mucous first started the end of Mar2021 or the first day of Apr2021. He went to ER on 11Apr2021. He also went back and forth with the doctor. They gave him allergy medicine. The ER gave him codeine cough syrup and Allegra D. Her GP has him on Sudafed now, Flonase, Allegra, and Benadryl. They were saying it was allergies, but he has never had a reaction like this with mucous. He has been wearing his mask too. He knows the allergy season was supposed to be bad, but they said on the news the masks were actually helping with the allergies. That people were having less symptoms. On an unspecified date, excess mucous was reported as worsened. He has fits at night nothing seems to change. He was not sleeping because he was constantly chocking and coughing every second. Last night, he finally fell asleep at 3 am and woke up at 9 am. They don't want to give him prednisone yet. He would have to wait 2 weeks after his last shot for it.
