@Marco_Piani @paimadhu Protection from vaccines (non-boosted) and previous infection seems close to zero (20% or less) in many estimates, also in terms of lived experience. Many instances of all-vaccinated groups (some even boosted) where everyone ends up sick.
@Marco_Piani@paimadhu对疫苗（非增强型）和先前感染的保护在许多估计中似乎接近于零（20%或更少），也在生活经验方面。很多情况下，所有接种疫苗的群体（有些甚至提高了接种率）最终都会生病。
