Effect of wild-type #vaccine doses on #BA5 hybrid #immunity, disease #severity, and #XBB #reinfection risk
Source: Journal of Virology, ABSTRACTVaccination against the wild-type (WT) severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus did not produce detectable levels of neutralizing antibodies (NAbs) against the BA.5 strain before it emerged. However, coronavirus disease-2019 (COVID-19) severity varied highly between unvaccinated, partially vaccinated,…

Here's an alteration I made of a FANTASTIC flowchart by "Your Local Epidemiologist" on Substack:

I amended it with TRG's COVID clan nicknames and added an arm (or whatever it's called) for BA.5.

Omicron strains of SARS-CoV-2 have displayed high transmissibility and immunological escape to antibody responses derived from natural infection and vaccination. Here the authors compare the antibody response to vaccination and natural infection, assessing neutralisation after vaccine doses and analyse the repertoire of such responses.
Protection against XBB reinfection conferred by a previous omicron infection with vaccination was lower and waned faster than protection against BA.4 or BA.5 reinfection, which is indicative of the greater immune evasiveness of the XBB sublineage. Although severe COVID-19 is uncommon, populations remain vulnerable to future reinfection waves from emerging SARS-CoV-2 variants despite high rates of vaccination and infection, as reflected by substantially higher reinfection rates during Singapore's XBB wave than during the previous BA.5-driven wave.
