Yea you're tight but it's true I mean if they don't get vaccines they'll infect themselves first and other unvaccinated people. Which is sad but maybe then they'll want to Gräben some of those needles..... Not the ones you think of right now, the legal, doctor and scientific certified ones but other than that they can't infect vaccinated people.
We'll leave earth in 10-20 years after all so maybe we should watch out who we carry with us to Mars.
SpaceX and NASA are currently working on it.
Competition is good for the consumer.
Actually, vaccinated people can infect others, as vaccines are not 100% and in fact, vaccines can mask the symptoms. Example, pertussis (whooping cough) vaccine can cause asymptomatic carriers (remember "Typhoid Mary"?). Personally, I'd rather that somebody who has pertussis, stay home because they know they are sick because they have symptoms, than have them think they are healthy and spread pertussis because "I had the vaccine so I'm healthy".

They can also lead to autoimmune disorders.
Followed. I can't wait to read your posts.
