They have found out that men are showing higher than normal PSA levels a few weeks after the 2nd dose of Moderna or Pfizer.; This is a spontaneous report received from a contactable reporter(s) (Physician).  A male patient received bnt162b2 (BNT162B2) (Batch/Lot number: unknown) as dose 2, single for covid-19 immunisation. The patient's relevant medical history and concomitant medications were not reported. Vaccination history included: Covid-19 vaccine (DOSE: 1, MANUFACTURER UNKNOWN.), for COVID-19 immunization. The following information was reported: PROSTATIC SPECIFIC ANTIGEN INCREASED (non-serious), outcome "unknown", described as "They have found out that men are showing higher than normal PSA levels a few weeks after the 2nd dose of Moderna or Pfizer.". Relevant laboratory tests and procedures are available in the appropriate section.  Additional information:He says that he does have reports to make. There is a website and it is really disturbing. There is a doctor who has shown that PSA levels, prostate specific antigen levels, are now being elevated after a guy gets the vaccine. This old thing is an anti cancer marker. You need to check the PSA level on a man, or a women, and if the level is elevated way up then you can be subjected to getting a biopsy. They have found out that men are showing higher than normal PSA levels a few weeks after the 2nd dose of Moderna or Pfizer. He asks, has Pfizer done any research to show how the vaccines that hey are using affect the PSA level? This is important because now 85 million men have been vaccinated with shot 1 and 2 from Pfizer and Moderna. He is in contact with one who has gotten their PSA level back and he is very upset about it. This individual is now going to the (with held) medical clinic to have a complete nephrological workup because the PSA level is 3 times what it was the year before. He has never seen that in his entire medical history and it is substantiated. The doctor's don't know if that is a real number or if it is because the individual had the Pfizer vaccine but he is going to find out at (with held).The caller's other question is, does the vaccine affect the measurements of the PSA antigen for for the prostate.He wanted to inform that according to drug safety that when the vaccine is used in men it disturbs levels to find out if it is prostate cancer or not. It takes away the ability to not have a biopsy. The biopsy is painful and expensive if you don't have insurance.Is there a Product Complaint: Yes. Caller reporting concerns with the Pfizer booster dose and mentioned that the overall total immunity has not gone up and therefore Pfizer should apologize to (with held) for calling it a booster in the modern sense where they can actually tell how many antibodies are produced. Apparently the 2nd shot of Pfizer after having the 1st shot doesn't boost immunity, they never said that it would boost immunity. Instead of producing antibodies it reacts partially with the antibodies that are already produced and that's why you get an increase of what they call local antibodies, it is just antibodies from the 1st dose that came swimming out of the glands because they have detected a surface protein and attacked. It is like a little swam of antibodies. If you were to measure those then it will report an increase in antibodies but that increase is not a booster, it is an increase only for a few minutes or seconds while the antibodies attack the surface proteins from the 1st shot. It is not increased like advertised to 25 times. It may be increased for a short period of time but just because it goes up right away that doesn't mean that the total amount of immunity has gone up from the number of antibodies that are counted. It is the local antibodies that are coming out of the glands and attacking the surface proteins from the booster dose or the 3rd shot. But if you were to count the number of antibodies they haven't gone up, they have actually gone down. There may be a slight increase from antibodies out of the booster but it is only a fraction of a booster's ability.    No follow-up attempts are possible; information about lot/batch number cannot be obtained. No further information is expected.
