You're going to be running your mouths either way. You might as well tell them your true intent, which is to save your own asses because regardless the efficacy of the vaccine you have been given, you don't trust it enough to bet your life on it. You'd be more comfortable mentally if you could know those around you have taken it as well. And lets even be more honest... you want to make money. Everyone wants to make money. They can relate and even respect you for it over that fake ass "help me help you" bull .
