Additional information: Relevant family history related to AE(s) was reported as none, stated that, they went online yesterday and spent 4 hours on trying to know what it could be and the only thing on everywhere they went through said it was a side effect of the vaccine and even thought they spoke to the doctor and no one knew anything, they only know that this thing was a side effect of the vaccine. History of all previous immunizations with the Pfizer vaccine considered as suspect (or patient age at first and subsequent immunizations if dates of birth or immunizations are not available): Patient has had first and second doses of the COVID vaccine. Additional administered vaccines (on same date as Pfizer vaccine considered as suspect) was reported as none. Prior vaccination (within 4 weeks prior) was reported as none. It was reported that, in the beginning of the call, the caller was very hard to understand due to loud noises in the background and poor call connection and he said that he was driving and currently in a bad patch but to let him pull over on the exit. Stated that, he was talking to the regular Pfizer customer service and they gave him phone number to report any adverse event with the COVID vaccine and for him to find out whether this reaction has been reported in the past. He said that, this was important to get out there. The reporter was a parent reported on behalf of his child. Declined mailing address. Patient Details: Declined date of birth. Primary Healthcare Professional Info: Declined to provide name, specialty, address, phone number and email address. Stated that, his son took the first and the second dose of the COVID vaccine and since yesterday, he thinks 16Apr2021, his son had woke up that morning with shooting pain in both arms and legs and he had a tingling sensation, a significant one from the inside. Stated that, his fingers, arms and legs had pain. Stated that, it was number one in his arms and his legs. Stated that, it was achy and tingling and his son said that it almost felt like someone had put 50 pounds of weight on his legs. Stated that, this was what his son noticed and the caller said okay, well maybe it would go away, maybe he had slept wrong but it didn't go away. Around at 02:30, they had read about emboli and suspected it was a blood clot potentially but they know Pfizer's COVID vaccine didn't have blood clots as an adverse event reaction but that didn't explain why his son was having tingling sensations in his arms and legs. Also, his palms had a slight reddish color to them. Stated that, he couldn't notice but his son said, that it was a bit more reddish than what he normal has on both of his palms. Stated that, his son has the tingling on his fingers when he presses and the tingling hasn't stopped so this was where they are at. Stated that, they were told to have it checked out but there was no need for rushing but that they should probably take him to the emergency room. Any AE(s) require a visit to emergency room or physician office: Patient had a teleconference with a doctor and would be going to the emergency room but as of the time of this report the patient had not been to the emergency room yet. Stated that, it was too much of a coincidence with it happening after the 2nd dose vaccine. Stated that, he couldn't tell whether it was a vaccine reaction but he thought Pfizer should know about this and if someone else has reported this before then he would like to know what was going on. Stated that, it was pretty significant and he would like to be able to speak to someone somewhere. Stated that, he thought this was a sure first stop to take this information. Stated that, the caller wanted to know from USMI whether the side effects his son has experienced has been reported previously. Also caller asked, so the agent has taken this information and what happens from here. Did the agent call people or not. Clarified with caller the date this began and informed him that yesterday was 15Apr2021, caller confirmed this start date and said that, his son was still experiencing this. He said that, it was slightly better at some times of the day. But his son was comparing this from negative 100 and saying it was negative 90 or negative 80 and his son gets numb to pain. But his son was still having significant tingling. Stated that, it was going up and down but it had never gone to 0. Stated that, he read online somewhere and the information was all over the place. Stated that, it didn't really explain why both arms and both legs are doing this. The doctor they spoke with said that, he didn't think it was a blood clot but it somehow impacted his son's nervous system and the doctor said to get an MRI or a brain scan. Stated that, with the leg pain and what his son was saying about the 50 pounds, the caller was not a medical doctor but it sounds almost like a blood clot to him. In the next few hours, they would be taking his son to the emergency room. Stated that, his son had a tele conference with a doctor yesterday evening and initially they didn't think this was anything serious but that maybe it was weird. For half of the day they thought maybe flu but the tingling didn't make sense and then at 02:00 AM in the morning his son did spoke with the teleconference with a MD doctor and that's when the doctor said not to go right now, but he will need to go to the emergency room in the next 12 to 15 hours to get checked with a neuro doctor with an MRI and whatever else they think that they need to do. Relevant test(s) were reported as none. The second dose NDC: 59267-1000-03. Probed for expiry date and this was not present on the COVID vaccine record card. He said that, they had some idea of where it was, it was in his arms they just didn't know whether it was the left or the right arm. The caller said that, all of them have had the vaccine. Stated that, probed for relevant medical conditions, test results or concomitant products and caller said that, there are none that he knows of. Stated that, it was important to give this information and flag it and have someone call him back from somewhere and he was sure that he was not the only person reporting this and he was hoping to be making some connections. Stated that, there was no way it was not the vaccine and the only reason he was saying that was because normally people will have a fever and other things but this was getting more serious in his opinion since the tingling hasn't subsided for his son and the caller was trying to figure out what the impact was of this. Enquired that, the second question he has was once they go to the emergency room and if they are to get more information from the emergency room was there a way to send that information to this department. The medical information request, caller wanted to know from USMI whether the side effects his son has experienced has been reported previously. Stated that, the reporter didn't know if the side effect was due to the vaccine or not. Stated that, they felt it was important to report it at least. Stated that, the reporter was wondering whether their data base had information of other reporting these symptoms. Stated that, the reporter knew with the J&J vaccine people reported side effects like this day 6 to 12 after receiving their vaccine. Stated that, they went to the ER yesterday. Stated that, they don't believe it's related to covid vaccine but they didn't know enough. It must be this or that, questioned was that covid related. Stated that, they had no data to say it's related or not. They stated they have no information from Pfizer which says there's any data or not. So, what the reporter wanted to know was: in their data base had people have reported this or not. Stated that, Pfizer must be classifying what people are reporting. If there are more cases that have been reported this or not and as their data base gets updated would they call or notify. Reporter stated the concern, so the reporter just wanted to make sure that, the reporter was reaching the right department. Stated that, the reporter was looking for Covid reaction for the second dose of 6-13 days ok, are there any kind of reaction. One of the family member, the reporter's son got a Covid vaccine second dose, on 6th day exactly, he started reporting really heavy tingling on both arm and both leg and real heavy weight on his leg, initially they thought it's a may be blood clot we spoke to a doctor on daily medicine, they are not even sure it's a blood clot they don't think so, because this happening on both arms and both leg and the palms are bit red and very very heavy just almost like his leg has got ache and he felt like somebody has put like 50 pounds weight on his leg. Stated that, he wanted to report this and wanted to know are there any incident. Stated that, the reporter wanted to find out whom the reporter could speak in their chain to really understand this reaction. Reporter was informed about the medical information department. Reporter asked, that's what the reporter was asking initially, what was this department job, what are they going to do. Reporter was informed again about the medical information department. Reporter asked, who could then take this report from his behalf, the reporter wanted actually log a system with this reaction because they are in a process of getting him in an emergency care but it will take him few hours to get the emergency care. (Further clarification unknown), the reporter wanted to get this log in their system. Reporter was informed about the role of Pfizer drug safety and medical information department. Reporter stated, question was ok, were they not going to report this incidence, how did they take a concern and an adverse reaction, what they did. Reporter confirmed it was the Pfizer covid-19 vaccine that the patient took. Reporter stated that, vaccine was taken on 19Mar2021. Expiration and LOT#: stated that, the reporter didn't had it hand.
