I'm kinda skeptical about this new nasal vaccine thingy. Like, yeah it's a good idea to boost mucosal immunity and all, but we gotta be careful not to rush into something that might not work for everyone, you know? 
I mean, we're talking about Covid-19 here, a super contagious virus that affects people of all ages, and these vaccines are still in the experimental stages. I get that scientists wanna try new approaches, but shouldn't we be a bit more cautious before we start handing out shots left and right?
And what's with all this fuss about pan-coronavirus vaccines? Is it really necessary to develop one that covers all variants of the virus? Can't we just focus on finding a vaccine that works for now?
I'm not saying these nasal vaccines are bad or anything, but let's take a step back and think this through before we start celebrating. We can't afford to get ahead of ourselves here.
