Additional Information: Caller is a consumer asking if coughing is a possible AE with the Pfizer Biontech COVID19 vaccine. Caller noted that the lot number for her two children (8 and 11 years old) was the same even if they were administered four days apart. Caller added that the dose for her children was pre-drawn in the syringe so she asked for the bottle and took a picture of it. In addition to that, caller noticed that the lot number for her booster is different from her children but she figured it might be because her children has the vaccine with orange cap. Caller wants to know if group of vials can have the same lot number. DSU: E-transmitting duplicate AE Response: Spoken from my knowledge as a pharmacist that a batch of vials would have same lot number and that it does not mean a single vial would have different lot number from each other as distinct from the rest. Reporter Details: Caller states she is a scrub tech. The report 1 of 3 on callers 8 year old daughter.

States that the school nurse just called saying she is complaining of chest pain, that she got her Pfizer COVID shot and flu shot on 05Nov2021 and caller got a text at 11:15am today saying that she is complaining of upper left chest pain and does she get heart burn, her lungs are clear and her vitals are stable and that she would recommend notifying her doctor of the pain. States she also felt like she had trouble breathing and the nurse didn't observe any trouble breathing and her oxygen and vitals are good. Caller states that she herself can relate to the shortness of breath, it's like you pause to take a breath. Caller states they all got the vaccines done at the health department and when she went to school you show the patient the bottle of the vaccine and draw it up in front of you and when the younger one went on Friday she asked the nurse to watch her draw it up and make sure it was right. Caller states the nurse said it was already pre drawn up so that was pretty disturbing and then this. Caller wants to know if group of vials can have the same lot number.
