BOSTON (CBS) — Cruise ships may be back in business by mid-July – if a very high percentage on board have received the coronavirus vaccine. The Centers For Disease Control said in a letter to cruise ships obtained by CBS News they can only operate if 98% of the crew and 95% of passengers are fully vaccinated.

The CDC said it’s impossible to eliminate all health risks on ships, but the goal is to mitigate that risk. The high requirement for vaccinated passengers and crew comes with loosened testing and quarantine requirements, according to CBS News.
