New charts from the Centers for Disease Control and Prevention show that the rate of hospitalizations for people who werevaccinated was much lower than for people who weren't.
The rate of hospitalizations for unvaccinated adults rose sharply as Omicron spread in the US, while the rate for fully vaccineed adults remained low.
One dose of the J&J vaccine or two doses of Pfizer or Moderna were included in the fully-vaccinated chart.
In December, the unvaccinated hospitalization rates were 16 times higher according to the CDC.
For people who were not the primary reason for admission, the statistics are for COVID-associated hospitalizations.
The rate of unvaccinated people was 78 per 100,000, compared to 4 per 100,000 for fully-vaccinated people, according to the CDC.
It is not clear which variant was associated with these hospitalizations. Delta is thought to cause more severe disease and more hospitalizations than Omicron, according to Our World in Data.
The data about boosters was only available to people over 50. Boosters reduced the risk of hospitalization.
The data is here.
The data should be taken with a grain of salt.
Mark Jit, professor of vaccine epidemiology at the London School of Hygiene and Tropical Medicine told Insider that they don't account for non-vaccine-related risks.
Jit said that people who get vaccinations may be more cautious about COVID in general, or that they may live in states with less COVID risk.
According to the UK Health Safety Agency, protection from a third dose of Pfizer or Moderna vaccine against hospitalization with Omicron was about 89%, waning slightly to 83% at 10 weeks.
The UKHSA said that the protection against Omicron hospitalization after the second dose was 70%.
