Caller was age 34 and said she got the 2nd dose of the Pfizer COVID Vaccine about three days ago and started having headaches, taking Advil and the headaches are coming and going and were nothing serious and were off and on. Stated if the headaches were bad she took the medication Advil but they were not happening very often regarding the headaches; stated today she recently took a nap and was feeling rather hot and opened a window trying to get air movement and she felt kind of off in her chest area felt like she had to get fresh air and almost was overheating for a bit. Transferring agent stated the caller's question was that she wanted to know now that she has had the 2nd dose of the vaccine what did she need to do about staying home for 2 weeks and agent states she is sending the caller a link to the CDC guidance about post vaccine recommendations. Caller verified the information provided by the transferring agent and stated she had been having the headaches not very often and they are not too intense and she was eating and drinking water still and the headaches were coming and going; states today when she woke up from her nap she noticed she was feeling very hot inside her room and opened up a window and felt like she needed fresh air and wasn't sure but after that felt like she was doing ok.

Stated that headache began recently and states she drank water after she got the 2nd dose of the vaccine and was trying to get it and the headaches are recent like a day or two or two days ago when they began and would say it was a normal headache and not that intense and not bad and right now she can feel a little bit of a headache. Stated she was feeling hot and her chest area was feeling off and that began today and would say honestly she just had woken up from a nap and thought maybe she just got a little too hot and tried to get fresh air in there and once she did that she started feeling better. Caller stated she did not have the dosage of Advil and only took it once or twice and has not really taken it that often and does not know when or how much she took and has no lot number handy for the Advil at this time.
