does not believe it was effective/I don't think the first one was even working; supposed to be in the deltoid and if it is not in the muscle and is in the subcutaneous fat; his arm was a little sore where the needle went in; it was administered into the muscle and it was administered into the fatty portion of my arm and the shot was administered too quickly; This is a spontaneous report from a contactable consumer reported for himself. A 72-year-old male patient received first dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection, Lot number: unknown, Expiry date: unknown) via an unspecified route of administration, administered at an unspecified anatomical location on 28Jan2021 (at the age of 72-year-old) at a single dose for covid-19 immunisation. Medical history and concomitant medication were not reported. The patient received second dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection, Lot number: unknown, Expiry date: unknown) via an unspecified route of administration, administered at an unspecified anatomical location on 18Feb2021 (age at vaccination was unknown) at a single dose for covid-19 immunisation. He received both Pfizer vaccines. The first one on 28Jan2021 and second one on 18Feb2021. The reporter stated that he believed the first shot was not administered correctly because of the way it was done. He watched them inject the solution and stated that it was supposed to be in the deltoid and if it was not in the muscle and was in the subcutaneous fat it will not be effective, and he did not believe it was effective. He stated that he thinks the first shot may have not been administered correctly and he didn't think that he had got the effect of the vaccine like it should be. He didn't have any side effects. He didn't think the first one was even working because he didn't think it was administered correctly, he didn't think it was administered into the muscle and it was administered into the fatty portion of his arm and the shot was administered too quickly. It was way too fast and did not believe they could have put anything in. He received this in (State) and it was administered in a high school where there were no people in there other than the national guard and the people bringing it in and making sure it was mixed and at the right temperature. The person who administered it may not have been well-trained so they may have put it in too fast. He stated the second dose was done nicely. He stated he had no other side effects other than his arm was a little sore where the needle went in. He asked whether he could get a third shot to make up for the first one that did not work. Now he watched people getting the vaccine on TV in other places and they seem to take little bit of time to inject it. This was just like in and out so fast. The second one was great. He asked so, if he get a third shot, is it dangerous or will that be okay. The reporter wanted to know if it is safe if he receives a third dose of the vaccine because he thinks the first one does not count, so it would be like getting 2 doses. He stated he already checked with a medical provider and they don't have any knowledge of how to use it. He also contacted the CDC. He tried to contact the Chief Medical Officer of Pfizer, but he is no longer the chief medical officer. After a verbal response was provided, he stated he is just going to get the third dose and will tell them if he dies, they should just call us but then said he was kidding. He said he can sign up for the vaccine, it is very easy, he just has to say he is getting his first shot. The reporter stated it is really frustrating to not be able to get studies done on this [a need for a third dose if a first dose is invalid]. He stated, since he couldn't get any info ourselves, he guess he will have to be the guinea pig. He stated you can always pass this on to the higher ups. He wanted to know if a third dose would be safe to get or if it would potentially kill him. The reporter stated that J&J stopped giving their vaccine because they are having so many people coming down with adverse side effects. They were trying to keep up with Pfizer and Moderna and came out with it too quickly. Limited information was available over the call.  Information on the lot/batch number has been requested.
