I strongly feel like it's the other way round. There are already diseases where we have multiple doses, like Tetanus[1]. If they said "hey, turns out we need a third and a fourth dose like with Tetanus, and then maybe a booster every 10 years" then that would be fine, and I think most people would accept that. But the word booster suggests to me they want to become (I hadn't heard the expression before, but I love it) "the Netflix of vaccine". Especially now that the EU has declared that vaccination certificates will expire 9 months after the last vaccination. 1. https://en.wikipedia.org/wiki/Tetanus_vaccine https://en.wikipedia.org/wiki/Tetanus_vaccine
