Passed out; pounding headache/headache symptoms are getting worst; body ache; tiredness; This is a spontaneous report from a contactable consumer. A 22-years-old male patient (Son) received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection), dose 1 via an unspecified route of administration on 08Apr2021 (Batch/Lot number UNKNOWN) as single dose for covid-19 immunisation. The patient's medical history and concomitant medications were not reported. My son is having a tough time with the vaccine. Everyday he has a couple of side effects. He started with body ache and tiredness on unspecified date Apr2021. He had a pounding headache. His headache was moderate today. However, the headache symptoms are getting worst. Generally, the symptoms last a day his have been getting worst for 7 days. He has been taking Tylenol and Advil. But the Advil doesn't even seem to hep anymore." headache is a common side effect reported with the vaccine. If the symptoms persists or get worst please consult your HCP. Please note blood clot has not been associated with the vaccine. Patient is been experiencing what I considered to be pretty severe, I guess reaction in term of aches and headache. This morning he woke up with the pounding headache, he kid described it as pounding and I just I guess I want to ask because everywhere I read, it says mild headaches are common and aches and I understand that but I guess understanding why this, this is considered somewhat as severe reaction or is there anything he can do to alleviate the symptom and should he, I guess my question is actually I guess my question also is should he not possibly get the second dose if he is experiencing such bad headaches with the first dose. When paraphrased the concern, reporter stated, Yes, basically we are thinking if can do to alleviate it and then he could not get the second dose, if you have any advice, I guess and just let you know he went to his health center in the college he went to get a COVID test and a flu test just to make sure he doesn't have actual Covid or flu and those report I got yesterday and so they told him that it's most likely still vaccine reaction. When probed for event start date, reporter stated, I would say a day after, I would say 09Apr2021, I guess it's phantom (not clarified) with symptom, the first day he was just tired, as far as the headache that started on the 09Apr2021. He (son) also passed out after the vaccine, which I also did that I didn't have Pfizer I (reporter) had Moderna and I had that same reaction, so I think that sometimes happens to some people but that's it happens also. When probed for vaccination anatomical site, reporter stated, Outside of the body I guess, I don't know that for sure. Patient still having the problem (event), and out event outcome, reporter stated, Yes, I think persisting, I think it varies. Patient has been taking Advil (Ibuprofen) and Tylenol (treatment). The patient underwent lab tests and procedures which included influenza virus test: negative on 12Apr2021, sars-cov-2 test: negative on 12Apr2021.
