The COVID-19 vaccine isn’t guaranteeing that people won’t get infected by the virus. The first generation (my term) of the vaccine is only claimed to help keep people out of ICUs should they get infected by the virus.
In fact, neither is the vaccine claimed to stop victims from being contagious. That’s why experts are saying to continue wearing politically correct (imo) masks and social distancing even after you get vaccine.

So conceptually, everybody getting off a ship can be contagious with COVID-19 regardless of vaccine, and infect people who haven't had vaccine or aren't taking vitamin D3.
In the meanwhile, I'll continue to take vitamin D3 dietary supplement and eat foods containing zinc.

Corrections, insights welcome.
Not really a correction; just a clarification. Vaccines have never prevented a pathogen from entering a person’s body. If you have the polio vaccine, poliovirus isn’t magically prevented from entering your body. What the vaccine has done is prepare your body to immediately overwhelm the infection before it can do enough damage to cause any real harm. That’s why we don’t have kids getting paralyzed by polio these days.
The open question with the current COVID-19 vaccines is whether a vaccinated person could still transmit the virus to others. The real answer is “probably not”, but the caution being urged during the vaccine rollout is because we haven’t had time to sort out that answer so it’s theoretically possible.
Not directed at anyone in particular, just putting the information out there so there’s clarity on the subject of what the vaccines do and don’t do. We know they do a lot of good, but we don’t yet have the data to define the full extent of how much good.
