Neither are masks or social distancing. Ultimately if you go to a show you are saying I know I am at risk and possibly putting others at risk. Attend at your own discretion and to each his own. At this point I doubt many people attending any events or shows are uneducated about the risk involved. I've been going to toy shows all over the country for over a year now and finally caught the virus right here in my little town of 3000 people. I practiced all the protocols religiously since I have a compromised immune system but still caught it. You can't run from it and because the vaccine isn't 100% effective eventually everyone will have had or will have it unless you haven't left your house for two years. Not everyone is getting the vaccine either. I know one person that hasn't left the house but six times the entire last year.
