A 22-year-old male patient received second dose of BNT162B2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE, Solution for injection, Batch/Lot number was not reported), intramuscular, administered in Arm Left on 06Mar2021 08:30 (at the age of 22-year-old) as single dose for COVID-19 immunization. Patient had no medical history (including any illness at time of vaccination). There were no concomitant medications. The patient did not receive any prior vaccinations (within 4 weeks). No additional vaccines administered on same date of the Pfizer suspect. The patient never had AE(s) following prior vaccinations. The patient previously received first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE, Solution for injection, Batch/Lot number was not reported), via unspecified route of administration in Feb2021 (at the age of 22-year-old) (caller states it was exactly 3 weeks prior to his second dose which was on 06Mar2021) as single dose for COVID-19 immunization. It was reported that on 06Mar2021, within 12 hours of the vaccine the patient started experiencing pain in his left testicle and a little bit in his right testicle. The pain worsened over a couple of weeks to the rib cage and his back. He then started getting shooting pain that he experienced in both legs, but primary his left leg, his thighs, biceps, and abdomen. His whole middle section just like in the middle of him. A month after the second vaccine (Apr2021) he started with muscular twitches. They were not painful but do exist. They have had an MRI of the pelvis/abdomen with and without contrast. Couldn't find anything. Blood work 4 different times and nothing there. They were now seeing a rheumatologist. Within 12 hours of receiving the second vaccine, her son had a fever and chills which they kind of expected. The fever and chills went away. What never went away was the pain in his left testicle. Her son told her he felt like someone kicked him there. His right testicle had some pain, but not nearly on the level of pain as his left testicle. The pain seemed to travel to his abdomen, and ribcage primarily on the left side, and his lower back and upper back, and his chest. Immediately this pain started. They think the chest pain was more so a panic attack. Her son was freaked out about all of this happening so they are thinking the chest pain was from a panic attack- the pain in chest wasn't the same as the rest, that chest pain went away. Probably about a week after receiving the second dose, the pain her son was getting worsened to like a sharp pain, kind of muscular related. The pain was like a step up from the pain he was experiencing previously. This pain was really uncomfortable- it was a sharp, shooting pain, totally different from the pain he was experiencing before. Her son was having very sharp pain again in the same places including his testicular region. The pain went through his penis and down mostly his left leg. Sometimes he would have sharp pain in his right leg, but the pain was mostly in his left side. He was also having pain in his abdomen, on his left side, sometimes his right, but not so much in the back as far as the shooting pain. The caller confirms the pain was still ongoing. About 2 weeks ago, on his left side, he was having intense pain near his ribcage/ left abdominal area that does travel. She would say this was her son's hot spot for today. The pain still exists in other areas, but the caller believes the combination of Advil and Tylenol was holding the other areas at bay. The intense pain in his left abdominal area/ rib cage was his hotspot- it was not painful to touch, it's not on the surface, it's underneath. A month after the second injection, he was experiencing muscle twitches, but he didn't want to say anything because we all kind of twitch every once in a while, but this twitching was not the same. The twitch was not painful. The twitching could happen in his thighs, biceps, chest, abdomen, and right eye. Sometimes its one twitch or sometimes the twitch could last 3-4 minutes. The muscle twitching was ongoing and persisting at this time. She confirms these events happened after the second dose. On an unspecified date, the patient had 2 ultrasounds done, a MRI, EKG and blood work done. Nothing showed up at all on any of these tests. The only thing that showed up was that he had a low level of Vitamin D, which they were giving him 50,000 IU's for 8 weeks to get his Vitamin D up, but they don't think its related to the events he was experiencing. He was having adverse reactions to the vaccine. He's gone to multiple doctor's, specialists, so forth. She was told by the doctor to tell Pfizer they already completed a VAERS (Vaccine Adverse Event Reporting System) report. Caller was calling today to see if there is anything else her son can do or anybody they can talk to. Does Pfizer have any suggestions. The doctor's have done their due diligence. They were basically waiting to see if some of these medicines work, there's been nothing so far that's happened. They enquired if this was being reported by others and they were informed that do not see these types of side effects reported in the clinical trial studies for the PI section 6.1. They were informed that no medical/treatment recommendations can be provided and referred them to HCP. The AE(s) require a visit to ER twice and seen his PCP who referred him to a rheumatologist. Outcome of the events fever, chills, chest pain was recovered in 2021; panic attack was unknown; other events was not recovered.  No follow-up attempts are needed; information about lot/batch number cannot be obtained.
