COVID-19 vaccines were linked to an increase in all-cause mortality in a new peer-reviewed study that analyzed data from the Italian National Healthcare System.

Based on their analysis, a team of Italian researchers verified what they called “the real impact of the vaccination campaign” by comparing the risk of all-cause death among vaccinated and unvaccinated residents of the Italian province of Pescara.

In their univariate analysis, the researchers found the risk of all-cause death to be over 20% higher for those vaccinated with two or more doses of the COVID-19 vaccine compared to the unvaccinated.

In contrast, prior research done in the same region suggested those with three or four doses had a lower risk of all-cause death.

“We also found a slight but statistically significant loss of life expectancy for those vaccinated with 2 or 3/4 doses,” they said in the report, which they published June 30 in Microorganisms.

Dr. Peter McCullough told The Defender, “These findings call for an immediate halt of COVID-19 vaccination across the globe and a thorough investigation of what went wrong during the COVID-19 vaccine campaign.”

McCullough wrote on Substack that the paper’s main point is that “COVID-19 vaccination did not ‘save lives’ as so many in Washington have proclaimed without evidence.”

Alberto Donzelli, one of the Italian study’s authors, told The Defender the study is “an important advance” because it looks at all-cause mortality broken down by vaccination status, and accounts for confounding variables that may have affected earlier reports on COVID-19 vaccination and all-cause mortality.

Very few studies in the world have successfully done that, he said.

McCullough also told The Defender the study’s findings are “cohesive” with those of a recent German study — currently available as a preprint —  which found COVID-19 vaccination was linked to increased all-cause death in 16 German states.
