Additional information: Reporter was calling about a side effect with her 9 year old daughter's vaccine that she got yesterday. She was hoping to get more information on what to do. Caller confirmed it was for the Pfizer BioNTech COVID19 vaccine. When asked if it was the pediatric dose, she said she has a sticker that says "PED". They both got tested for COVID yesterday because she (the mother) ended up being sick, so her boss had asked her to go get tested. To be on the safe side she also had her daughter tested before they went to go get her vaccinated. They found out that the mother was positive and the daughter was negative. Reporter(mother) was hoping that the vaccine didn't trigger something completely crazy. Caller advised she was not sure if they were understanding her question. So she added: did her being positive and being around her going to affect her in any way. Reporter was coughing during the call. Reporter stated, "So her daughter got the first dose of the COVID Vaccine yesterday and she woke up and has started coughing today. She had only coughed like twice or 3 times so far but besides the arm pain and her being dizzy, reporter's concern was that the patient started to cough and turns out that she actually got, her test results for COVID were actually positive. So she don't know if it is rubbing off from reporter to patient or if it is a side effect from the vaccine yesterday. When asked if the reporter only wanted to report or wants any other information, Reporter stated, No, I want information. Reporter stated her daughter was about 60 pounds and thinks she was about 4 feet. The patient was scheduled for second shot on 01Feb2022. The patient did not received any prior vaccination (within 4 weeks) and also stated patient did not had other medical conditions, not that reporter had been able to identify." The patient was not well, reporter(Mother) did give her Tylenol, children's Tylenol for her pain and her sore throat. Reporter stated, "It was a bottle, it says 10mg for her weight size and that's her max weight and that would be all.  No follow-up attempts are possible. No further information is expected.
