About 6 months ago, this very issue was raised before the CITA. A CITA watersports meeting was held for discussion of the topic. As was expected, some members were dead set against it, other members were in favor of it, and others had no opinion. (Remember that the CITA watersports segment includes many more snorkeling operators than diving operators.)
The issue was tabled so the proposal could be more clearly re-written, and it was slated to be voted on again. However since then, CITA held their annual elections and a new BOD was voted in. I am pleased to say that I am one of the CITA Board members, representing the Watersports sector. The current priorities of the CITA Board of Directors is working with Government to formulate a safe reopening plan for the islands.
A safe plan can confidently be established. The VP of the CITA Board of Directors is Dr. Michael Tibbets (owner of Clearly Cayman,) who along with Kel Thompson have started their own initiative called Reopen Cayman.

Dr. Tibbets has collected vast amounts of data from other islands that are currently open, examining what works, and what doesn't, and can demonstrate that with a multi-faceted plan, the risk of contracting and dying from COVID19 is very slight. I'd encourage everyone to visit his site and take a look at it.
Many things are being considered for a safe reopening plan. The border reopening will consist of many things, not just a vaccine. Social distancing, masks, pre-arrival resting (Cayman does not do this currently,) regular rapid testing (data has suggested that frequent rapid testing is a more effective to less frequent PCR tests,) hygiene standards.
Vaccines are being considered of course, but this is not the magic bullet. As some of you may have seen, there is some reluctance on the part of some residents here to actually take the vaccine. A recent Cayman Compass poll has shown that only 60% of the respondents were willing to take one. Other local polls show even lower numbers. 70-80% of the population must be inoculated in order for herd immunity to take effect. There is also the availability of these new vaccines. Vaccines in and of themselves will not stop the problem, which is why a multi-pronged solution is required.
