Unvaccinated Californians were between 15 and 20 times more likely to die from COVID-19 than those vaccinated when deaths from the disease peaked in early September, according to state data.
The California Department of Public Health is releasing data on the vaccine status of people who test positive for the coronavirus as well as people hospitalized with COVID-19 and who die from it. Their data shows that the death rate among unvaccinated Californians aged 16 and older skyrocketed in early September, peaking at 13 average daily deaths per million on September 6.
In contrast, the average daily death rate from COVID-19 for fully vaccinated Californians peaked at just under one in a million in late August. By September 6, it had fallen to 0.75. COVID-19 death rates for vaccinated and unvaccinated Californians have fallen since September and now average 0.26 and 5.8 deaths per million per day, respectively.
Death gap between vaccinated and unvaccinated people exists in the United States A study released in early September by the Centers for Disease Control and Prevention, which tracked more than 600,000 cases of COVID-19 in 13 states from April to mid-July, found that unvaccinated people were more than 10 times more likely to be hospitalized for the disease and 11 times more likely to die from it.
In the CDC study, unvaccinated people were 5 times more likely than vaccinated people to test positive for the coronavirus. In California at the end of September, unvaccinated people were about 7 times more likely to test positive than those vaccinated.
These data show that the vaccine is not as effective in preventing overall infection with the delta variant as it was against previous strains; Another study released by the CDC in August found that once delta became the dominant coronavirus strain, vaccines went from 91% effectiveness in preventing infection to 66% effectiveness.
However, it also shows that vaccinated Americans remained highly protected against serious illness and death during the last wave. Until at least the end of August, vaccines remained about 90% effective in preventing hospitalizations from COVID-19, according to the CDC.
CDC data also shows that as of October 7, states with higher immunization rates have, on average, lower death rates than states with less immunization.
It is also likely that these statistics do not fully reflect the effectiveness of the vaccine, as vaccinated people are on average older than unvaccinated people and are therefore more likely to become seriously ill and die from COVID-19.
Even for unvaccinated Californians, death rates from COVID-19 have dropped significantly since early September. The state’s average death rate is currently the lowest of any state in the United States, at just 0.3 deaths per day per 100,000 people according to the CDC. Its weekly case rate is also the lowest of any state, at 66 new cases per 100,000.
California’s current low death rate is likely due to a combination of rising immunity from high past case rates, strict public health rules, and above-average vaccination levels across the board. of State. As of October 6, 61% of all Californians were fully immunized, compared to 56% of all Americans.
