A 55-year-old male patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection), first dose on 19Jan2021 17:00 (Batch/Lot Number: EK4176, expiration date was not reported) and second dose on 09feb2021 (Batch/Lot Number: EM9809, expiration date was not reported), both administered in left arm, via unspecified route of administration as SINGLE DOSE for covid-19 immunization. Medical history included hypertension and had no known allergies. Concomitant medication included nebivolol (BYSTOLIC) at 5mg daily. The patient did not receive any other vaccines within 4 weeks prior to the COVID vaccine. Prior to vaccination the patient was not diagnosed with COVID-19. On 27-MAR-2021 08:00 the patient tested positive of the covid 19 over a month after fully vaccinated and had full out symptoms of covid 19. The patient reported that he tested negative for Covid in the beginning of Mar (14Mar2021) but then tested positive for Covid on 25Mar2021 and was symptomatic. Upon follow up it was reported that the patient is disappointed in the vaccine because he got the same symptoms of covid as you would expect with covid- loss of taste, loss of smell, fever, and chills.He is aware that you cannot get Covid from the Covid vaccine and he knows that there is a chance that he might not be protected because the vaccine doesn't work for everyone. He is calling to try and understand why this might have happened. The patient was concerned if something could have been wrong with the vaccine batch that was used and what he should do about that. He was very disappointed and depressed at the situation and also did not expect to be so sick as well. He thought maybe one of the batch was bad or not good.The patient knows that the vaccine has 95% efficacy so he knows that he may have fallen into the 5% and gotten covid after the vaccine. There was a medical information request. The patient wanted to know if Pfizer we checks on batches not being effective? Maybe they didn't do anything correctly or administered it incorrectly. The patient does not believe the vaccine caused an adverse reaction, he believes the symptoms were from the virus. The caller wants to figure out what happened and if the batch was bad. The patient feels that he added everything he needed in his report and does not want to add anything or file a new report with this agent today. The patient underwent lab tests and procedures which included sars-cov-2 antibody test: negative on 14Mar2021 Qualitative NAAT, sars-cov-2 antibody test: positive on 25Mar2021 Qualitative NAAT. There was a product complaint to report as the patient tested positive for covid on 25Mar2021 after receiving both doses of the vaccine. The second dose of the vaccine was received on 09Feb2021.The outcome of the events was unknown.  Follow up (02Apr2021): New information received from a contactable consume includes: expiration date was not reported, medical information details added.
