Caller verified the information provided by the transferring agent and states for her mother, she has no idea if it was previously reported but she was two hours away from her mother and the patient called the caller at that time and was pretty sure the patient got the Pfizer shot and her stepdad also got the Pfizer covid vaccine and knows they both got both doses of the vaccine; states the patient ended up in the emergency room due to chest pain and numbness and tingling down her arm and shortness of breath which is what happened to her and with her mother's health allergy history she got some of the more severe side effects and symptoms but it was not necessarily a full on allergic reaction and they gave the patient Benadryl and watched her for four hours and did tests which came back fine and with the 2nd dose of the vaccine told the patient to contact her HCP and take Benadryl as soon as she was done with the 2nd dose as this could happen again with the 2nd dose. Caller states she has several questions and concerns about herself and talked to her own doctor and has not yet gotten vaccinated but with her health and autoimmune and allergies to 20 medications and that has caused serious allergic reactions and she was at a cross roads and was definitely afraid of catching covid because she does not have an immune system to fight it and asked if it was going to be safe for her to get the Pfizer covid vaccine.
