So basically li-key mimics those who have had covid and provides stronger and longer immunity than the mRNA vaccines can provide. The message out there from our current administration is that "we must protect the vaccinated from the unvaccinated". This is the wrong message to send about vaccines in general. What they are saying is the vaccines do not work all that well if a vaccinated person needs to worry about someone NOT vaccinated. So If I have had both Moderna vaccines (which I have had) and I wear a mask all the time, I still have to worry about someone unvaccinated? That says to me that either vaccines or masks do not work, or both.
