A new study released by the Texas Department of State Health Services shows that during the month of September, Texans not vaccinated against COVID-19 were about 20 times more likely to suffer a COVID-19-associated death and 13 times more likely to test positive than people who were fully vaccinated.
According to the Texas Department of State Health Services, an analysis of data from the four-week period from Sept. 4 through Oct. 1 shows that vaccination had a strong protective effect across all ages.
While the impact varied across age groups, it was most pronounced in younger groups.
The Texas Department of State Health Services said the risk of COVID-19 death was 48 times higher in unvaccinated people in their 30s and 63 times higher for people in their 40s, compared with their vaccinated peers.

There were fewer than 10 COVID-19 deaths among fully vaccinated people ages 18 to 29 compared with 339 deaths among unvaccinated people in the same age group, the Texas Department of State Health Services said.
According to the Texas Department of State Health Services, the study, which matched electronic lab reports and death certificates with state immunization records, is the state's first statistical analysis of the real-world impact of vaccination against COVID-19 in the state.
Public health researchers focused specifically on the September period to measure the effect of COVID-19 vaccination as the more contagious Delta variant surged across Texas, the Texas Department of State Health Services said.
"This analysis quantifies what we've known for months," Chief State Epidemiologist Jennifer Shuford said. "The COVID-19 vaccines are doing an excellent job of protecting people from getting sick and from dying from COVID-19. Vaccination remains the best way to keep yourself and the people close to you safe from this deadly disease."
