The patient's concomitant medications were not reported. Vaccination history included: Bnt162b2 (Consumer stated, "That is looks like, Okay that is a same LOT#, it is also showing an LOT EW0171 and that was given 20May2021.

Additional Information: Consumer stated that I had a very severe reaction to the second shot and I had the shot on 10Jun2021 and I have been trying to get to a specialist to determine whether it is safe for me to have a booster shot and nobody here including my medical provider seems to know what type of specialist I need to go to tell what happened to me, whether it is safe for me to take the booster and They say to go the allergist, you go to the allergist and they don't know anything about the Pfizer shot. So, they don't know how to test for an antibody. Do you know doctors that are specialized in testing to see what happened to me and whether I can take another shot. Consumer was informed about the Role of Pfizer Drug Safety. Report was an intern and also a professional 'Consultant'. No, I am not a healthcare professional." (Hence captured as consumer or other non healthcare professional). Consumer stated, "It was immediately you know the first couple of days afterwards and what happened is that I got blister under both of my arms, my lymphatic glands underneath each arm, blister but particularly the blistering was heavy on the left arm which I got after the shot. It happened immediately, it stayed blistered and swollen under each arm for almost 4 months, during the time that it was blistered and sensitive, I went through massive fatigue and I was slept almost 18 hours a day for almost 4-5 months, very little activity, I was only up may be 5 or 6 hours a day and I could do things like go to the store and get food or may be visit somebody but I could only stay up for may be 3 or 4 hours before I had to go to bed again. That went on for like 4-5 months then it started to go away, the blistering started to go away at the same time I started getting stronger. When paraphrased the above reaction, Consumer stated, Specifically on the lymphatic glands underneath the arm, It was the lymphatic gland. Consumer stated, I had like a 3 or 4 days reaction to the first dose. The Second dose was 10Jun2021 and I was given it from (Withheld) EW0171 (Captured as provided). Consumer stated, It doesn't have a expiration date. LOT# (First shot): Consumer stated, That is looks like, Okay that is a same LOT#, it is also showing an LOT EW0171 and that was given 20May2021.There is an expiration date on that first dose, It shows an expiration date of Aug2021. Consumer stated, yes and they didn't had anything to do to help me, none of the doctors knew what to do and I also (Incomplete Sentence) the problem is I kept asking if there's a specialist who know what to do. No one know where to send me that's the problem. None of the doctors know how to test see what I reacted to, they didn't know what to give me, they just told me to rest at home. For other Medical Condition: Consumer stated, I do have allergies with the chemical sensitivity, that is why I wondered If I have a chemical reaction to it. In my medical history  have had problems with allergies when I was younger, I have not have problems with allergies that I am aware of but I have to be careful with injections because I am allergically sensitive.  No follow-up attempts are possible. No further information is expected.
