This The reporter reported for a 20-year-old male patient (Reporter's son) via medical information team.  A 20-years-old male patient received bnt162b2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE, Formulation: Solution for injection, Lot Number: Unknown), via an unspecified route of administration on 14May2021 (20-year-old at the time of vaccination) as 1st dose, single dose for COVID-19 immunisation. Medical history included illness from an unknown date and unknown if ongoing. He has been to the doctor for sick visits 20 times in 20 years. The reporter also stated that there are no mental health issues noted in their family history. The reporter also stated that the patient was overall healthy with no significant medical history in the past. The patient's concomitant medications were not reported. The reporter reported that patient received the first dose of the Pfizer COVID 19 vaccine on Saturday and by Monday was having flu like symptoms, fevers, chills, diarrhoea, chest pain, shakiness, as well as other neurological symptoms such as anxiety and depression. He has been to the doctor for sick visits 20 times in 20 years. After receiving the COVID 19 vaccines, the patient has been seen by the doctor 3 times in one week. The patient's side effects have lasted 3-4 weeks. The reporter would like to know commonly reported side effects of the vaccine and their duration. The reporter would like to know the efficacy of only one dose of the Pfizer COVID 19 vaccine as the patient was hesitant to get the 2nd dose due to the side effects noted from the 1st vaccine. The reporter was advised per "attached" dose for efficacy after one dose. The reporter was not satisfied with this data and wanted to know more about what she had been read about online. The reporter was advised caller agent as could do some more research and contact her back with possible additional data which caller agreed to doing. Upon call back on 14Jun2021, advised caller per (website "PRIVACY") from 10Dec2020. The cumulative incidence of COVID-19 cases over time among placebo and vaccine recipients began to diverge by 12 days after the first dose, and 52.4% vaccine efficacy (95% confidence interval: 29.5, 68.4) was observed between dose 1 and dose 2, indicating the early onset of a partially protective effect of immunization. Two doses of vaccine provide the maximum protection observed. Ten cases of severe COVID-19 were observed with onset after the first dose. Nine cases occurred among placebo recipients and one among BNT162b2 recipients. The reporter would like to know dosing interval between shot one and two. Patient had their 1st dose on 14May2021 and has not received the 2nd dose yet due to side effects from what they felt was caused by the 1st dose of Pfizer COVID 19 vaccine. The reporter received response as "you should not get the Pfizer-BioNTech COVID-19 vaccine if you had a severe allergic reaction after a previous dose of the vaccine or if you had a severe allergic reaction to any ingredient of the vaccine. The decision to receive the second dose for any other reason cannot be made by Pfizer. We refer you to speak to your healthcare provider about the risks of the vaccine compared to the risks of potentially not being fully protected against COVID-19 infection. Your healthcare provider knows your health situation and has access to information that can better help inform this decision". The reporter wanted to know should the patient get the 2nd dose of the Pfizer COVID 19 vaccine after the reported side effects of flu like symptoms, fevers, chills, diarrhoea, chest pain, shakiness, as well as other neurological symptoms such as anxiety and depression. The reporter received response as do not administer Pfizer-BioNTech COVID-19 vaccine to individuals with known history of a severe allergic reaction (e.g., anaphylaxis) to any component of the Pfizer-BioNTech COVID-19 vaccine. The outcome of the events was resolved in 2021  Follow-up attempts are needed. Information about lot/batch number has been requested
