The patient received her 2 doses of the Pfizer covid 19 vaccine and the booster. After her 2nd dose she had some reactions "saliva building up in mouth, tingling of lips and tongue and throat started to close off. After the caller received her booster dose yesterday (15Dec2021) she had those same reactions like after the 2nd dose but additionally had abdominal issues like she is used to experiencing when ingest nuts. As per caller, her stomach felt like her gut was being squeezed or pulled and usually when that happens she has to immediately take Alavert or Benadryl to make it stop. Yesterday while she was at the center the doctor told me to go ahead and take the Alavert and if that didn't work they would give me something else. She stayed a little longer to make sure she was ok, the Alavert did help and she started to feel better. When she got home she was instructed to take Benadryl which she took and fell asleep. Today she still have a little tightness in the gut and throat, but she know it will pass by tonight like it did last time. Caller is allergic to peanuts and all nuts. Caller added in her medical records it says she should take Septra (it cut off breathing) or another product for the bladder (for overactive bladder). She has never had a reaction to vaccines. But anything with coconuts, peanuts that's even found in shampoo she get hives and rash. After the booster, she couldn't taste her dinner. She had left over food that had bacon in it and she couldn't taste the bacon. She had vanilla and chocolate ice cream and couldn't taste the chocolate. Her taste buds were off. She had a flu shot a couple of weeks ago and had no problems. This is the first time she has had a reaction to any kind of shot. She had all her shots has a child. Caller reporting adverse event with second dose and booster dose of COVID19 Vaccine. By the time she gets the shot and walks to where she has to sit, she gets saliva to build up. It is a lot of saliva in her mouth. Inside her lip starts to get tingling and her tongue. Then after 15 minutes she could feel a weird taste in her mouth. Her throat starts to close off. With the second dose she took Alavert. It is an antihistamine tablet that melts on her tongue right away and then had to take Benadryl when she got home because it was difficult to swallow. After the booster, at the 15 minute mark, her abdomen started to get really tight. She has allergies to peanuts, coconut, and all nuts. That sensation in her gut was like if someone didn't tell her there was coconut in something she ingested. She took Alavert and it seemed to help and within a minute or two the pain in her abdomen stopped the squeezing. She needed Benadryl when she got home. What ingredient in this vaccine could be doing this to her? Medically she needs to know so she doesn't get a Pfizer medication with that ingredient. Her throat is still a little bit swollen. The abdomen area feels a little tight. The last time it lasted 24 hours.
