Takeaway fron "worst version"
quote:
More breakthrough infections, especially among people who previously had BA.1. Compared to BA.2, BA.2.12.1 is only modestly (1.8-fold) more resistant to antibodies from vaccinated and boosted individuals. But BA.4 and BA.5 are substantially (4.2-fold) more resistant.
More symptoms. BA.4 and BA.5 are also better at replicating in lung cells than BA.2 — a shift that could mean, according to one experimental model, that they’re more “pathogenic” as well (i.e., more likely to make you sick).
More resistance to treatments. At the same time, BA.4 and BA.5 appear to be 20-fold more resistant than BA.2 to Evusheld — an important monoclonal antibody treatment that has been providing preemptive protection for immunocompromised people.
