BA.5 much more infectious than BA.2; Kislaya et al.: "SARS-CoV-2 BA.5 vaccine breakthrough risk & severity compared to BA.2: a case-case and cohort study using Electronic Health Records in Portugal"
SOURCE:
“The odds of complete primary vaccination (aOR=1.07, 95% CI 0.93-1.23) or booster dose (aOR=0.96, 95% CI 0.84–1.09) among the BA.5 cases were similar to the BA.2 cases, suggesting no significant differences in vaccine effectiveness against infection for the BA.5 lineage compared to BA.2(Table2).
Higher odds of reinfection were observed in BA.5 cases compared with BA.2 (aOR=1.43, 95% CI 0.92-1.26). Combining vaccination and previous infection status, the aOR of BA.5 infection was 1.70 (95% CI 1.40- 2.05) times higher than for a BA.2 infection, within those with complete primary vaccination and with previous infection. Among those with booster dose vaccination and previous infection, the aOR was not statistically significant (aOR=1.18, 95% CI 0.95-1.47).”
But what does this mean for the never-jabbed who have acquired natural immunity? Same risk of reinfection? Impossible to tell because so few Portuguese are not jabbed yet so many jabbed have gotten sick, and more than once. I think the jabs have wiped out Portuguese population's ability to cope with all future strains and the tiny percent that is never-jabbed are so poisoned with the exosomes from the jabbed that they too are probably toast. Because hardly-jabbed South Africa certainly doesn't seem to have this problem of same vulnerability to BA.5. They seem pretty immune to it. And the summary should have said, "no significant differences in vaccine INeffectiveness against BA.5 or BA.2."
