Unvaccinated adults were 6 times more likely to contract COVID-19 over the course of the month, and in the last week of August, they were 19 times more likely to be hospitalized with illness than fully vaccinated adults.
Some states and local jurisdictions have recently started posting data on the number of COVID-19 cases and death and hospitalization rates by vaccination status on their dashboards.
The CDC works with health departments to link case surveillance data to vaccination information systems for their own analysis.
While the CDC’s analysis isn’t entirely comprehensive, the data released late Thursday is a federal first look at COVID-19 risks based on publicly available vaccination status, with plans for regular updates.
Case-by-vaccination data is available from 14 states across the United States, as well as New York City and King County in Seattle, which represents about 30% of the total US population.
Death data is available from all but one of those jurisdictions, while hospitalized COVID-19 data is available from a different set of 13 states.
CDC data shows that the risk of death from COVID-19 for unvaccinated adults has decreased in recent weeks as the frequency of new cases has decreased across the country.
By the last week of August, COVID-19 death rates among unvaccinated adults were about 30% lower than in the first week of the month, dropping from an incidence rate of 13 deaths per 100,000 people to about 9 deaths per 100,000 people. 100 thousand people.
But since last April, the risk to fully vaccinated adults has been no higher than 1.2 deaths per 100,000 people.
Last week, the Director of the Centers for Disease Control, Dr. Rochelle Walinsky, noted that there are still unvaccinated people in the United States who are not protected from the virus.
With the risk of infection and death declining, CDC data also showed that the hospitalization rate among unvaccinated adults continued to rise, rising more than 80% from the first week in August to last week.
The risk ratios vary according to the age group. For example, the rate of hospitalizations due to COVID-19 among adults under 50 years of age is about 15 times higher for unvaccinated people than for fully vaccinated people.
For those aged 50 to 64, the hospitalization rate is 31 times higher for unvaccinated people, and for those 65 or older, the hospitalization rate is 16 times higher for unvaccinated people.
According to the Centers for Disease Control, “Vaccinating against COVID-19 reduces your risk of getting sick and helps protect you from a pandemic even if you do get sick.”
The agency is leading studies to continue monitoring vaccine efficacy and breaches over time.
An analysis by the Kaiser Family Foundation estimates that as of Wednesday, there have been more than 90,000 preventable COVID-19 deaths among unvaccinated adults over the past three months, with more than half occurring during the month of September alone. .
After dropping to seventh place on the list of leading causes of death last July, COVID-19 returned to second place as the leading cause of death last September, according to the Kaiser Family Foundation.
Heart disease was the number one leading cause of death in the United States last September, while the Corona virus was the leading cause of death among adults aged 35-54 years during the last two months.
According to the Kaiser Family Foundation, “With the rapid uptake of vaccines during the months when vaccines first became widely available, deaths from COVID-19 have decreased dramatically.”
“However, with the emergence of a delta mutated from the most contagious coronavirus, inadequate vaccination rates, and local and state governments easing social distancing restrictions, COVID-19 cases, hospitalizations, and deaths have increased again,” she added.
