That has been the case for quite a few people actually, a lot of the kids and grandkids on behalf of our elderly patients seen today rearranged appts today as adamant that want to get the Pfizer. Last week a few delays as adamant about wanting the AZ.
Currently being allocated at random from what I can tell, we just get shipments of one or the other and book patients in. It is a pretty complex issue I feel with numerous factors to consider - scientific, logistically, supply, efficacy. I got the pfizer but for me getting one as soon as possible was always the main thing, and would have got AZ if I could have earlier.
And news that Johnson and Johnson are about to drop their ENSEMBLE 1 and/or 2 trial data for the Janssen vaccine in a few weeks (multinational, high number of participants in covid-hit countries) for consideration of FDA approval I think it'll be an interesting dynamic to observe in the future about perception and preference with regards to the approved vaccines once we have infrastructure in place to give them out in the community en-masse.
