Subject: RE: low risk groups

Faunsdale, AL
How many people who share a cabin aren’t related and had common contacts and exposures BEFORE they boarded the ship?

I don’t know what protocols the cruise line put in place other than requiring evidence of vaccination before boarding, but I doubt anything they did is intended to stop an airborne virus spreading within one cabin on a ship.

In summary, looks like the vaccine was a success in that nobody else got the virus from those two and they apparently didn’t get sick enough to have to cut their cruise short.

From the cruise line’s perspective, what’s not to like about this situation?

Again, contrast this cruise to the ones before they shut down last year.

You seem to want a vaccine that’s around 90% “effective” depending on what endpoint is selected to be 100% effective in preventing infection.

It’s the old trap of the desire for perfect being the enemy of effective.

The way that a vaccine that’s less than perfect becomes effective is when everyone in a group takes it. Seldom have we had vaccines that are as effective as the ones we have against COVID-19. But we have relied on the majority of people getting vaccinated and by and large it has worked. Only time is doesn’t work is when a group of people that are in contact do not get vaccinated.

As long as its an occasional unvaccinated person here and there, the system works. Get a community that doesn’t vaccinate and they can easily have an outbreak if there’s ever any exposure to the disease.
