Avram, your timeline sounds similar to what I recall from Bourla’s book. Delta started like June, maybe by July Israelis reported to Pfizer their findings that vaccine effectiveness against Delta falls after several months which was not the case with Wuhan covid. Then, Pfizer announced a booster idea (probably, several weeks before official request). So, Bourla says they immediately got angry responses (I do not recall now – public or private) as this seemingly did not match official line that Biden defeated the virus. But after Pfizer shared the data, gov accepted the logic. A classical case of emotional partisan reaction later over-ridden by seichel.
while on the topic, there is a feeling of total breakdown of communications under Biden. First year is full of discussions with Warp Speed, Trump calling, Kushner resolving problem with some officials. During Biden times, Bourla is stuck dealing with specific gov people with no calls to Biden or Kamala or Hunter. And it is clear who Bourla likes. Biden told him that he knows other people who lost family in the Shoah and Dr. Jill smiled at him in England …
In addition to the above, US trade rep called him at home before going public with giving away Pfizer’s IP to the “world”. Bourla argued against. Bourla’s teenage son listened to the conversation and commented afterwards: “do you realize that she called you just to check the box she talked to you, she did not care about the points you were raising”. Bourla pickup up the phone and called
Biden and resolved the question. Oops, did not happen.
