Japanese researchers have determined that the vast majority of post-Wuhan coronavirus (COVID-19) “vaccination” deaths occur within the first 10 days following injection.

A paper they put together that was published in the journal Cureus lays out how the researchers came to this determination.

The risk period in the study was defined as 10 days or less following injection with “vaccination day” representing Day 1. The control period was defined as day 11 through day 180.

Two groups were established based on age with Group 1 representing individuals aged 65 and older, and Group 2 representing individuals aged 64 or younger. Group 1 saw 1,311 deaths and Group 2 saw 247 deaths.

Based on these established parameters, the researchers found that the death toll within the 10-day risk period was 71 percent for Group 1 and 70 percent for Group 2.

Within the 10-day risk period, researchers noted that most deaths occurred on the second day, meaning one day after the person got injected. After that, the bulk of remaining deaths occurred on days three and four, meaning most people who die from COVID injections do so within the first four days after injection.

COVID jabs often mean instant death

There are all sorts of reasons outlined for these “unexplained deaths,” with the vast majority from Group 1 involving heart damage, i.e., ischemic heart disease and heart failure. Many of the remaining deaths occurred because of aspiration pneumonia and asphyxia.

Other noted causes of death in Group 2 besides the aforementioned include cardiac arrhythmias, subarachnoid hemorrhage, myocarditis, and pericarditis. Most of the myocarditis and pericarditis deaths occurred in men.

“Some myocarditis/pericarditis cases may be included within the unexplained deaths category,” the study states, noting once again that men are much more likely than women to succumb to this form of post-injection death.

“Myocarditis is a complication of vaccination, especially in young adults and adolescent males.”

Author Yasusi Suzumura calculated sex ratios for all-cause deaths, identifying notable differences between men and women that he says are eye-opening in terms of what they reveal.

“If there is no effect on the occurrence of death, there should be no difference in sex ratios by period,” the study explains. “Thus, this finding indicates that vaccination may influence the occurrence of death during the risk period and might be associated with death.”

All of the cases involve only the BNT162b2 mRNA (modRNA) injection from Pfizer and BioNTech. All data on death numbers was obtained from Japan’s Ministry of Health, Labor and Welfare (MHLW).

“The results indicate that the BNT162b2 mRNA vaccination may influence the occurrence of death during the risk period,” the study further reads, avoiding directly implicating the shots as the cause of the deaths.

Despite its limitations, the study offers a closer look into the ugly world of post-injection “unexplained death,” or what many also refer to as “sudden death.” The tens of thousands, if not millions, of excess deaths being reported all around the world appear to have a direct cause, and that cause is COVID-19 jabs.

Commenting on the data in a U.S. context, cardiologist Dr. Peter McCullough said that similar data exists domestically to strongly support causality “for the nearly 1,150 immediate deaths observed.”

Through Sept. 29, 2023, the government-run Vaccine Adverse Event Reporting System (VAERS) has reported 18,188 deaths from COVID-19 injection, with 1,150 deaths occurring on the very same day as injection.

“In addition, 2,040 miscarriages, 9,053 heart attacks, 17,433 permanent disabilities, 5,057 myocarditis/pericarditis cases, and 36,184 severe allergic reactions were also reported,” reported the Epoch Times.
