7 cases in HCWs who had been vaccinated 10 days before symptoms, which is considered the cut-off for protection. This is out of nearly 29,000 vaccinated HCWs. Of the 15 breakthru cases, 7 were HCWs. So the rate of vax failure was higher in that population than in the total.
Thanks Helen. Any idea how many cases in non-vaccinated HCWs? Or do they simply not exist? (I assume nearly all HCWs were vaccinated)
I don't think you can assume that. There are hordes of traditional healers & but there are no registries of those clinics. A lot of the nosocomial transmission has occurred there. They are offered vaccine if authorities know about them, but they often don't.
