A couple of additional 'beyond the headline' thoughts: First, it is worth noting that though the data is available online, the study has yet to be peer reviewed, which is a key part of the process. Not that it is guaranteed to change anything, just worth noting. Also worth noting that the true nature of the findings here is 'notably more adept at breaking through', which I don't think is hugely surprising. Doesn't mean Pfizer is completely ineffective against it, just less effective. Finally, this is a bigger story in a place like Israel where nearly all of their vaccines administered were Pfizer. Obviously, studies are to come regarding Moderna and J&J, but here we've administered all three vs. just one. Worth noting that key difference, IMO.
