To greatly reduce the risk of severe disease?
"Researchers analyzed data on more than 4,500 patients admitted to 21 U.S. hospitals with respiratory diseases between March and July and found that unvaccinated patients accounted for 84.2% of COVID-19 hospitalizations, 91% of COVID-19 deaths and nearly 94% of those who either needed a ventilator or who died"
The article you are referring to posts statistics that are 4-5 months old. In addition, the information in the UK article contradicts the information put out by U.S. News & World Report.

"The above chart shows the number of recorded Covid-19 deaths in England over a period of three months by vaccination status.
What’s interesting about this is that whilst cases and hospitalisations declined in both the fully vaccinated and unvaccinated between week 33-36 and week 37-40, there was only a decline in deaths during the same time frame in the unvaccinated population, whilst deaths among the fully vaccinated population actually increased.
Between week 33-36 and week 37-40 Covid-19 deaths fell from 726 to 557 in the unvaccinated population, but increased from 2,094 to 2,136 in the fully vaccinated population.
But for a third time, where things get both interesting and concerning is the difference between week 37-40 and week 41-44. That’s because the number of deaths among the unvaccinated increased by just 30 to a total of 587 between weeks 41-44, whilst the number of deaths among the fully vaccinated increased from 2,136 to 2,732 between week 41-44.
One problem with those charts is they aren't adjusted for the relative sizes of the vaccinated and unvaccinated populations.
There may be more total issues in the vaccinated population but a much higher rate of issues in the unvaccinated.
This is akin to those stupid articles that talked about certain vaccine lots causing problems without having any idea how large the various lots were.
The analysis is meaningless without that data yet the authors make bold claims based on it.
