Covid vaccines 95% effective against infection and 91% against hospitalization among US veterans

COVID-19 vaccines are effective in preventing infections and hospitalizations among U.S. veterans, a new study shows.

Researchers from the Department of Veterans Affairs and the Food and Drug Administration looked at data from the first three months of the shots’ availability.

They found that the Pfizer-BioNTech and Moderna vaccines had 95 percent efficacy against infection and were 91 percent effective in preventing hospitalization.

There were also no deaths among fully vaccinated veterans.

The team says the findings show how protective the vaccines were early in the rollout and why it was so important to get veterans — who are a population at increased risk of severe Covid — vaccinated quickly.

Only 22.8 out of 100,000 fully or partially vaccinated veterans tested positive for COVID-19, compared to 280 out of 100,000 unvaccinated veterans

Nearly one in five veterans whose data was collected were vaccinated against Covid, with older vets more likely to be vaccinated than their younger counterparts.  Pictured: A soldier receives a Covid vaccine injection in Fort Knox, Kentucky, on September 9, 2021

Researchers collected data from 6.6 million veterans between December 2020 and March 2021.

They found that 1.3 million — nearly one in five — received at least one shot of a COVID-19 vaccine during that period.

Older veterans at this time were more likely to receive the injections than their younger counterparts, although researchers found little difference in vaccination rates across racial lines.

At the time, the Covid vaccines were not available to all Americans, but only to certain groups, depending on what state a person lives in.

Seniors were prioritized in almost every state — which is why older veterans had better vaccination coverage — but veterans with certain comorbidities or who were frontline workers were also eligible in some states.

More than 472,000 study participants had tested for COVID-19 at some point during the study period, with 15,000 positive cases detected.

Of the positive cases, 41 were breakthrough cases detected in fully vaccinated people, 270 in partially vaccinated veterans, and 14,799 in unvaccinated.

Researchers, who published their findings Wednesday in JAMA Network Open, found that only 22.8 of the 100,000 participants who were at least partially vaccinated in the study had contracted Covid.

The infection rate has increased more than tenfold for the unvaccinated, with 280 in every 100,000 people contracting the virus.

When adjusting for other factors, such as age, race and geography, researchers found that the vaccine is 95 percent effective at preventing infection and 91 percent effective at preventing hospitalization.

There were also no COVID-19 deaths among fully vaccinated study participants.

Partial vaccination — meaning you get just one shot from a series of two doses — still also provides 64 percent vaccine effectiveness protection against infection.

One injection was also 48 percent effective at preventing hospitalization and 63 percent effective at preventing deaths, the researchers found.

While the results of the study reflect the initial effectiveness of the Moderna and Pfizer-BioNTech vaccines, the situation in America has changed since the data was collected.

The Delta variant, a highly contagious strain of the virus that caused a huge wave of cases in the US over the summer, had not reached the country as of March.

More recent data also shows that the vaccine’s effectiveness at preventing infection declines over time, meaning the first users of the injections – who would be among those vaccinated seven months ago – will not be as protected now. as then.

To counteract its waning effectiveness, booster shots have been made available to people over the age of 65 or with co-morbidities that put them at serious risk for the virus.

Currently, in the US, 65 percent of people have received at least one dose of a COVID-19 vaccine and 56 percent of residents are fully vaccinated.

According to official data, just over six million booster doses have also been administered.
