The real-world data here in the US has supported continued efficacy against hospitalization and death. The CDC's current numbers[1] say that unvaccinated people are at 11.3x greater risk of dying than vaccinated people. The current guidance for boosters is specifically for those groups where efficacy has waned more over time (elderly, immunocompromised) and there's some evidence that Moderna's higher initial dosage has caused its efficacy to wane less (and the booster is only half the original dose). My point is that frequency of boosters and necessity of new boosters is not at all a clear picture. It has now been 6 months since I got my second shot and I'm not even eligible for a booster, let alone having someone mandate it.
