Additional information: Caller was his mother. stated, She was calling for her 16-year-old male son who received dose of the vaccine Pfizer BioNTech Covid-19 Vaccine on Saturday. I believe it was the first dose and he was feeling very drained today and they were asking if it was safe for him to go ahead and do sports or if he should stay home for a couple of days and let him recover from feeling tired and I have told her to contact the physician to ask that questions but since she did say he was feeling very drained. He got his first dose of the COVID vaccine 28Aug2021, last Saturday. He was not feeling well. She doesn't feel like this was unusual based on the stuff she read. He did not have a prescribing doctor. He has a headache. He feels weak and drained. He was exhausted all of the time. He was sneezing. His cough showed up and stayed. His biggest complaint was fatigue. He was having allergy symptoms like foggy brain and feeling icky. He noticed them yesterday, 29Aug2021. His cough started yesterday evening. He has been sneezing all day. He has gone down hill since then. Today was definitely worse than yesterday. He has had asthma since he was like 7 years old. Her husband has all the cards from the vaccine appointment yesterday. Her husband did say that (Name withheld) couldn't take the same vaccine he got because of his age. So she isn't 100% sure if he got Pfizer. Caller stated her sons albuterol inhaler isn't as easy to read as other medications. Caller doesn't have lot or expiration on the albuterol.
