All those who have been vaccinated against Covid are less likely to die from any disease or metabolic cause, even not related to the virus. This was announced by the American CDC (Centers for disease control and prevention), in a report on disease control and prevention, publishing the study carried out on 6.4 million people who received the double dose of Pfizer and Moderna vaccine or the single-dose by Johnson & Johnson.
Pfizer vaccine for children 5-11 years, “90.7% effective and safe”

And the results speak for themselves: compared to the non-immunized, the vaccinated showed a lower mortality rate for each study category, age, sex and ethnicity. Without vaccine, the probability of death with or without a virus is 11 times higher. The cohort study, the first conducted on a large socio-demographically diverse population, took into account vaccinations and health-related deaths that occurred between December 14, 2020 and July 31, 2021, revealing that people who underwent two doses of Pfizer vaccines showed a relative risk of death of 34%, which is reduced to 31% for those who received Moderna and rises to 54% for those who opted for the single-dose Janssen.
Of the 3.5 million who received the Pfizer vaccine, 9 percent were between the ages of 12 and 17. In all, 2.6 million people received Moderna and 342,169 Johnson & Johnson. The percentages were standardized and compared with the death rates of 4.6 million people who received at least one seasonal flu vaccine in the past 2 years. For all age groups, the comparison was improved except among the youngest, so “there were no significant differences between adolescents between 12 and 17 years compared to non-vaccinated. Men and women showed comparable relative risks. by type and dose of vaccine, as well as all ethnic groups, always with lower mortality than their unvaccinated counterparts “.
And if mortality rates among recipients of the Janssen vaccine were not as low as those of the mRna vaccine, “it could be due to differences in risk factors, such as previous health status” or differences in medical history that led to the vaccinator to opt for the one instead of the other two. Astrazeneca, a viral vector like Johnson & Johnson, was not considered in this research because it was not administered in the United States.
Covid: let’s go beyond the third dose and think about new vaccines

As the researchers write, “people vaccinated for Covid had lower mortality rates than those who were not vaccinated, even when coronavirus-related deaths were ruled out. This adds to mounting evidence from other studies showing that vaccines are effective against infection, serious illness and death “, reinforcing the safety profile of vaccines and reassuring all those who are still hesitant about it. Previous research on mortality with or without mRna vaccine conducted on residents in some nursing homes had already yielded similar results, but data on the general population had never been evaluated so far.

“The Covid vaccines authorized by the CDC have been shown several times to be safe. This study confirms this once again, also in terms of absolute mortality”, he comments Stanley Xu, a researcher at Kaiser Permanente Southern California in Pasadena who led the study team. “Part of this is likely due to the fact that people who get vaccinated tend to be healthier than those who don’t. The lower mortality risk suggests substantial effects on healthy vaccinates, which will be explored in future analyzes,” he added. In any case, this discovery strengthens the safety profile of Covid vaccines “.
