While mRNA vaccines by Moderna and Pfizer-BioNtech are most effective against Delta variant with effectiveness rates of 90% or better against hospitalization and death, AstraZeneca’s and J&J’s vaccines follow at 80% or better.

That, along with China’s unusual zero-tolerance policy, is a recipe for continued lockdowns and quarantines as continued Covid-19 outbreaks are guaranteed.
