You got that right, but missed the important part where the lower rate excludes COVID-19. The title of the CDC table says:
"Number of deaths and standardized mortality rate (deaths per 100 person-years) not associated with COVID-19..."
If the data is correct, then it turns out that being vaccinated dramatically reduces the death rate for people in the age group of 18-44 from everything else but COVID-19, along with whatever effect the vaccines have on reducing COVID-19 deaths.
Normally that would make people suspicious of the study, since the taking the data at face value suggests a very strong protective effect from the vaccine against any kind of death. Nobody thinks that the vaccine is effective against breast cancer, heart disease, suicide, homicide, or being in a fatal work or auto accident, but the CDC study either has something else wrong with it, or the vaccine is effective against all of those causes of death.
The Freepers making fun of the study know that we are looking at another poorly done CDC study, not a miracle drug.
Or it means that people who chose to get vaccinated were healthier to begin with. That's called the "healthy vaccinee effect."
And why lookee here. Why, that's exactly what the CDC said it means right there, in the very same study:
The lower mortality risk after COVID-19 vaccination suggests substantial healthy vaccinee effects (i.e., vaccinated persons tend to be healthier than unvaccinated persons) (7,8), which will be explored in future analyses. Mortality rates among Janssen vaccine recipients were not as low as those among mRNA vaccine recipients. This finding might be because of differences in risk factors, such as underlying health status and risk behaviors among recipients of mRNA and Janssen vaccines that might also be associated with mortality risk.
Among persons aged 12–17 years, mortality risk did not differ between Pfizer-BioNTech vaccinees and unvaccinated persons; only 12 deaths occurred in this age group during the study period. The unvaccinated group might be more similar to the vaccinated group in risk factors than are vaccinated and unvaccinated adults.
