The caller stated his wife, and 2 daughters and one son. Caller stated they all had the Pfizer vaccination administered last month, they are past the 2 doses and past the 2 weeks. Caller stated his son and himself have both received "both Pfizer vaccine doses and have had NO side effects at all."  His wife and one daughter had both Pfizer vaccines, and one daughter has had only one dose of the vaccine. The four family members received their 2nd Pfizer vaccine dose 3 weeks ago and this is when his youngest daughter received her 1st Pfizer vaccine. The caller stated he is "very concerned about the side effects" his wife and 2 daughters are having daily. "They are having twitching and pulsating mainly in the legs and sometimes other parts of the body. This occurs frequent and infrequently depending on the time of day." The caller states his wife, son, one daughter and himself did not experience any side effects after their first dose. His youngest daughter is having the exact same symptoms the other 2 women are having after she has received only one dose. Caller stated his wife, and 2 daughters are still having issues with pulsating or twitching, mainly in the legs and sometimes all parts of their body. Caller stated they waited to see if it would subside or improve, but it is still persisting, and they are concerned. Caller stated he went to the website, and he can see what main side effects occur, but this doesn't come up. The caller stated they have read all information and have been seen by their PCP for these symptoms and the HCP said, "it will go away, don't worry." The caller is questioning why these side effects are not listed on the info sheet about side effects. There has been "no progress in the past 3 weeks, as far as decreasing symptoms and it has "taken a toll emotionally and physically on them, this has affected their lives." The caller stated their PCP is leaving his practice and enquired if they need a new primary, or should they see a specialist - Like a neurologist. The caller's biggest issue is there is nothing close, symptom wise to what they are experiencing. He enquired will it go away or never go away and where they supposed to go from here. Caller stated he is kind of worried, and enquired is this something that has also been heard of or anything that speaks to either the nervous system or the pulsating and twitching.  No follow-up attempts are possible; information about lot/batch number cannot be obtained. No further information is expected.; Sender's Comments: Linked Report(s) : US-PFIZER INC-2021748991 same reporter/drug/event, different patients.
