She then contacted her rheumatologist. Her rheumatologist told her that withheld has not put any recommendations in writing to tell doctors what to do related to booster shots. She saw withheld on television yesterday saying there was going to be a special meeting to discuss immunocompromised patients and the Delta variant of the Covid 19 virus that is taking over the country. She has not heard more about that yet, other than they are recommending everyone to wear masks, outside and inside. She stated that her rheumatologist was not against her getting the Pfizer vaccine series after getting the Moderna vaccine series. He just told the patient that he could not tell her to go and do it.

History and Investigations: Covid 19: Caller states that she had Covid 19 for 29 days.

States a man had wrote in about his wife who has Rheumatoid Arthritis and Lupus. The wife of this man had the same antibody test as the caller after the Covid Vaccine and the results were negative. The man had wrote into the article asking what does that mean. She stated I have nothing against Pfizer I know this was a new disease and they did their best to come out with a treatment. Yesterday I spent the day reading journals/studies and the efficacy is still listed at 95.3% that is not true anymore, the variants have become strong, the vaccine cannot fight them off as well, but it was still a good product. The delta variant is out of control and it will get worse, we donot want people to get overconfident, so maybe the data should be updated (on the efficacy). I do thank Pfizer and they probably saved millions of lives including mine.
