Above is a typical CDC Covid-19 vaccination blank. For many, the card may be the only record they may have of being vaccinated against the virus, and many people guard this card with their lives - and for good reason. In places like New York City, one must show proof of vaccination in order to enter public spaces such as museums, stadiums, restaurants and more. It is an effective "Get out of Jail free card" for people like me, as it allows most of us to go about our lives almost as if nothing has happened.
Early in the history of Covid-19 Vaccines, some state governments recognized the need for a vaccine passport that a person could use his/her cellphone to display, allowing the person to safely leave the CDC card at home. New York was one of those states with its Excelsior Plus App. Sadly, due to politics, our Federal government stated that there would be no need for a National vaccine passport. As a result, Americans may be forced to bring the CDC card with them when traveling overseas, instead of showing the results of an internationally recognized app on their phones.
For someone who was at "Ground Zero" for the pandemic in the USA, I find it appalling that the governors in some states have fought to ban businesses from requiring people be vaccinated to enter their property or use their services. This year, NCL has had to sue the governor of Florida to nullify its requirement that everyone on their ships be vaccinated. NCL sees the requirement as a net positive, as it realizes that people will want to know they are at minimal risk of being infected on the cruise - it can't afford another 500 day shutdown due to another Covid-19 outbreak. The governor of Florida, on the other hand, wants the votes of the anti-vaxxers, and it willing to do whatever it takes to get what may be the deciding votes in his next election.
Since I will soon be going on a cruise, I will carry my CDC vaccination card with my passport - and keep it safe at all times. NCL's 100% vaccination requirement is an asset for them, as it allows their ships to sail into the Bahamas - a nation which requires that ALL visitors show proof of vaccination before entering the nation. If NCL did not require every passenger to be vaccinated, it would not be able to bring passengers to their private island, nor would it be able to provide a cruise experience equivalent to what they offered on roughly the same route before the pandemic.
By this time next year, I am hoping to take another cruise. At that time, I hope that the worst of the pandemic will be gone. The remaining anti-vaxxers may have gotten a free ride because the vaccinated rest of the population will have allowed us to achieve herd immunity. If we had had their cooperation, we'd have achieved this status much earlier. At least, we're in sight of achieving this goal....
