New CDC rule

[Pcardad]

Yellow fever has been around a long time. Covid, being so very new, is far more dangerous because no one has any immunity yet (or very few do). I believe all the cruise lines will require the vaccine no matter what...those who cannot take it will probably, IMO only, not be allowed on board.

I agree, vaccination is the way to go along with mask wearing.  Some cruise lines have already said no vaccination, no cruise.

That is not the same. ..yellow fever is not covid. It’s not contagious.

I can’t take the yellow fever vaccine. It’s a “live” vaccine.  The Covid vaccine is NOT.

The difference is that Yellow Fever typically doesn’t have human to human transfer ( unless there is blood to open wound contact), so even if someone unvaccinated was infected via a mosquito bite, it is highly unlikely they would or could infect someone else on board.  This is very different than with an air borne pathogen such as SARS-CO2.  

The major challenge, even with a large percentage of the population being “vaccinated” is the lack of long term antibody formation as shown by confirmed reinfections. The “ vaccine” only reduces the severity of COVID, it does keep one from having and spreading COVID, which a true vaccine does.  Twenty years after having a measles vaccine, the antibodies can still be found in your blood, current studies indicate that COVID antibodies begin to drop off beginning around 90 days...they are unsure of the level needed to allow for a reduction in severity of disease.

We don't know this yet.  You would expect the acute antibody titer to go down after the acute infection or initial reaction to the vaccine, so the fact that has been observed is not really that concerning.  If the antibody titer remained high, it might actually be worse, suggesting a chronic unresolved infection.  The immune cells should remember how to respond to the antigen and rapidly create new antibodies if they encounter it again.

 

Not enough time has gone by to assume the immunity does not last longer.  Maybe it doesn't, but IMO it very likely lasts significantly longer than 90 days.  With time we will get the answer this question.

I would think the cost of those testing positive, finding a place and cost would be the cruisers expense not Regents.

There has to be something set up in the various countries. They’re probably going to have special hotels set up for positive tourists to isolate. The US State Dept is recommending  all Americans traveling out of country to obtain travel insurance which covers this.
