The unvaccinated have made a choice, but It effects others who for medical reasons are unable to be vaccinated. The people who refuse the vaccine are the selfish ones, not those under 12. Take the vaccine and make life better for others or be selfish but admit you don't care about anyone but yourself. DO THE RIGHT THING. GET VACCINATED, WASH YOUR HANDS AND STAY HOME IF YOU ARE SICK.There's a whole segment of the population THAT DOESN'T HAVE THE CHOICE YET.
The unvaccinated are giving the virus time to adapt to target that demographic.
ETA: You know...the one that really loves WDW and can't get vaccinated yet.
