I'm saying if you want the vaccine, which presumably you're in the office to get that for that reason, right immediately after it's been released for the public, you're unlikely to have your pick of vaccines by means of choosing this vaccine over that. If the U.S. for instance only get access to one vaccine you can wait if you're able to but you may be waiting for an undetermined amount of time before another vaccine is able to be cleared for distribution. That's what I was meaning, down the road you may be able to do what you mentioned. I'm all for it if the U.S. for instance has the ability to have multiple vaccines for people to choose from, I'm realistic in saying I wouldn't bet on it. The poster who brought it up was saying they'll wait and pick one with a better efficacy rate and they want the best one. At least in the U.S. it's whatever has been deemed cleared for usage for the public and that vaccine may not have the most efficacy rate over a vaccine another country is using. That's why I brought up Gardasil and Cervarix.
