It’s early yet, and we don’t have a lot of information. This is an interesting “anecdote” however. There are some data out there that suggest the mRNA vaccines lose efficacy over time much more rapidly than one thinks of when thinking about vaccination. E.g. maybe as little as 5-6 weeks. But not a lot of information about that and it could prove to be faulty data. Also, they have been trying to find a use for mRNA technology for many many years, never once finding it worked well for anything. These are approved under “Emergency Use”, e.g. not “approved by the FDA” but merely allowed because the perceived benefits outweigh the perceived risks. Only time will bear the truth out in that logic.
Do have a link for that info. I’d like to see that data - sounds interesting.
