Quit listening to charlatans, protect yourself, your family, and society, get vaccinated.
No antibodies<antibodies<antibodies+vaccine. Even the Pope has been vaccinated. Sorry, you are NOT special. You are NOT smarter and a 'free thinker.' You buy into fear and anger from charlatans, that's all.
If you want to cruise and not be vaccinated, tough luck. There is a reason 'outbreaks' on ships are so well contained, and case severity is so low. It's a single reason, vaccines.
