Well, Moderna and Pfizer’s are both mRNA-based, but presumably different in some ways because they were made by different teams (and I thought I saw Bret or Dr. Malone say he would have preferred Pfizer over Moderna, though it’s not in my summary). But AstraZeneca and J&J are “adenovirus vector vaccines”, using chimpanzee adenovirus ChAdOx1 and serotype 26 (HAdV-D26) respectively; the latter was “under investigation as [a] protective platform against HIV, Zika, RSV infections and are in Phase-III clinical trials for Ebola” in early 2019. Now, adenovirus vector technology is pretty new. Even so, it would be an impressive coincidence if the risks were both substantial and the same for a ChAdOx1-based vaccine, a HAdV-D26-based vaccine and both RNA vaccines. Sure, they all use the spike protein in some way — probably it’s necessary for the immune system to recognize the spike protein — but (i) eventually our bodies will encounter the spikes, either via SARS-Cov-2 or via vaccine, and I’ve seen no one make a case that a live, replicating virus is safer, and (ii) the evidence/argument for the protein itself being dangerous hasn’t been made clear in any of the stuff I’ve seen.
But my main point is the seeming lack of interest from Lawrie, Dowswell, Kirsch et al. in the question of relative safety, because this is a known failure mode of anti-vaxxers all the way back to the Wakefield study. That infamous paper apparently linked the MMR vaccine to autism, yet many anti-vaxxers acted like there was some fully general link between all vaccines and autism.
