Alaska’s state epidemiologist says vaccines have proved better than 90% effective against hospitalization and “in the mid-to-high 90 percentage range” against death.

Vaccinated parents are catching COVID as schoolkids bring the virus home
Nationwide between Aug. 5 and Aug. 12, about 121,000 children tested positive for the virus. That’s a 23% increase over the prior week.
Alaska’s breakthrough COVID cases on par with expectations, state epidemiologist says
Health officials point out that means vaccines offer quite a bit of protection — especially because vaccinated individuals are much less likely to have serious symptoms or die from the disease.
A CDC document gives new details on just how dangerous the delta variant really is
One CDC chart shows that it could be as contagious as chickenpox, which is one of the more transmissible viruses out there. It spreads more easily than the common cold, the 1918 flu and smallpox.
Alaska’s rare COVID breakthrough cases are far less worrisome than stalled vaccination rate, experts say
Scientists say the vaccines appear to be only slightly less effective against the delta strain and still provide strong protection from severe disease and death. And research suggests the shots may also make it less likely for vaccinated people to spread the virus even if they test positive.
