New study shows fewer people die from COVID-19 in better vaccinated communities

A major U.S. study published BMJ today found that very few people die from COVID-19 in the best vaccinated communities.

The survey results, based on data across 2,558 counties in 48 U.S. states, show that counties are larger. prevention coverage has a reduction of more than 80% in it mortality rate compared to unvaccinated districts.

This major benefit complements the collection of evidence demonstrating the individual benefits of COVID-19 immunization. The related editor also suggested that encouraging people to continue using the vaccine saves lives.

As of April 11, 2022, more than 11 billion COVID-19 vaccines have been vaccinated worldwide and the goal of the World Health Organization is to vaccinate 70% of the world’s population by mid-2022.

However, while previous immunization studies have shown benefits at the individual level, the greatest effect on the level of COVID-19 immunosuppression remains unknown.

To address this, researchers at the US Centers for Disease Control and Prevention (CDC) set out to evaluate how increasing vaccination exposure affects mortality and COVID-19 cases.

Their findings are based on the more than 30 million people exposed to COVID-19 and the more than 400,000 deaths associated with COVID-19 in 2558, who were reported in the second year of the disease, between December 2020 and December. 2021.

They measured efficacy by comparing the reported effects of COVID-19 mortality rate in districts with low (0-9%), low (10-39%), moderate (40-69%), and high (70% or more) vaccination-defined as adult population ( 18 years and above) who received at least one dose of COVID-19 prevention.

After considering the potential factors, the researchers found that increased immunosuppression in the districts was associated with a reduction in COVID-19-related mortality rates.

For example, in the first half of 2021, when the alpha variant of the coronavirus dominated, COVID-19 mortality was reduced by 60%, 75%, and 81% in sub-regions with low, average , and general immunosuppression, respectively. , compared to districts with less weight.

Figures corresponding to the time reduction were 57%, 70%, and 80%.

A similar decline in mortality was also seen in the second half of 2021 when the delta region invaded the United States, although it had a small impact on legal measures.

This is a observation study, so it cannot establish a reason and the researchers say that too much limitation should be considered when interpreting these data. For example, additional symptoms of serious illness, such as hospitalization, have not been investigated, and they have no control over other factors such as the rules of wearing a mask and physical restraint at the time, which may have affected their outcome.

However, they did show that the results remained the same after further careful study, suggesting that they endured research. And they say: “Future research could benefit from assessing the economic impact of improvement public healthsuch as labor costs and great indoor product as a result of the reopening of the community. “

This study adds to the evidence that vaccines can prevent infections and illnesses on a large scale, says Professor Christopher Dye at Oxford University in a related editor.

“The findings of this study also make it clear that many lives can be saved, and they can be saved, by encouraging people to continue to use the vaccine in the face of reduced immunity and new strains of coronavirus. and achieve even greater population, ”he said.

“My life is an issue that others will be exploring. Currently, this new study is a boost to the COVID-19 injection,” he said.

The prevalence of COVID-19 is highest in both urban and rural areas
