On September 5, Carnival Cruises will amend its requirement that all passengers be vaccinated before they can sail. Before then, unvaccinated Carnival passengers had to file a request for a vaccine exemption before they could sail. And Carnival will no longer require vaccinated guests staying on board for under 16 nights to be tested for the Chinese coronavirus.

Vaccinated passengers will still have to provide evidence of their vaccination and unvaccinated passengers must show a negative coronavirus test from within three days of sailing.

Cruises of more than 16 nights may have different restrictions.

Part of this is due to Joe Biden’s inflation and the need to recover financially from the impact of the pandemic.

And part of this is due to common sense.

These vaccines don’t stop infection with the virus. The vaccines don’t prevent the spread of the virus to other people. Biden has been vaccinated twice with four boosters and even though he is one of the most protected people in the world, he had got the virus twice.

In fact, the more the Chinese coronavirus vaccines are studied, they are shown to be dangerous than the disease itself. Almost all cruise lines require vaccination and that severely limits their customer base.

Cruise lines are meticulous for cleanliness and they fear an outbreak of any disease. They don’t want anyone to get sick.

Requiring unsafe vaccines for a virus that is fading and not much worse than a common cold is unscientific and also unnecessarily bad for business. The cruise industry employs hundreds of thousands of employs from 100 countries who need the work.

Let’s hope that the other cruise lines follow Carnival’s lead.
