but also have other data as well.
The big slide deck on that is here (PDF) - https://www.cdc.gov/vaccines/acip/meetings/downloads/slides-2021-9-23/03-COVID-Oliver.pdf
I think there are several factors going on -
1.) Two of the vaccine types have never been used before (mRNA), let alone on such a huge scale, so I really think they are trying to hedge enough so that if something goes wrong in the future, they won't be pilloried for the rest of their lives.
2.) They are trying to function in a literal unprecedented global pandemic, the likes of which has pretty much surpassed the 1918 one (where obviously none of them were even born then). And back in 1918, the medical personnel didn't even know what was really causing the pandemic, yet here we are today with a complex knowledge of what the virus "looks like" down to the molecular and genetic level, and generally know how it gets into cells within the body to replicate. But the end result, even with a vaccine, has ended up being almost the same as that a century ago.
3.) Many of them are techies in their fields but that doesn't translate well to the general public. There are certain expectations for vaccines in general that have always been par for the course, but the message that had gone out initially in order to get as many people vaccinated as possible, was by sortof glossing over what they normally tell people when it comes to vaccines. The repetitive "get the vaccine and 'get back to normal'", ended up being the albatross around their neck because the public got the impression that a vaccine could be a "shield", and any medical doctor or immunologist knows that has never been the case. But to the public, anything less than what was promoted - "getting back to normal, including going maskless", became a "failure", and that seemed to set the stage for a lot of frustration.
We have a long way to go but hopefully what will come out of this is a new way to do annual vaccines, like the flu one.
