He just wanted to know what is going on and why was he experiencing these side-effects.

He added that Pfizer should have access to the information about the Moderna covid vaccine. Patient stated that "I can understand why people don't wanna get their shot but the people who are not getting their shots are paying the consequences for it. Now, the people who are getting their shots, they are not getting the accurate proper response of what the shot is about. That's completely wrong." Patient asked what was the difference between the Moderna covid vaccine and the Pfizer covid vaccine.  No follow-up attempts are possible; information about lot/batch number cannot be obtained.
