“Twelve-month all-cause mortality after initial COVID-19 vaccination with Pfizer-BioNTech or mRNA-1273 among adults living in Florida: Statewide cohort study”

Now appears as peer-reviewed study in Global Epidemiology!

In closely matched cohorts of nearly 2M Moderna & Pfizer vaccinees in Florida, the latter (Pfizer) showed substantial higher all-cause, cardiac, non-COVID and COVID mortality post 1st mRNA COVID vaccine dose.

These results were robust to adjustments on pre-vaccination cardiac hospitalizations as well as SARS-CoV-2 infections.

This study adds to a growing evidence that the mRNA COVID vaccines of Moderna and Pfizer may have different non-specific effects.

Recent study “In Vivo Blood Kinetics and Transcript Integrity of Three mRNA–Lipid Nanoparticle Vaccines in Humans” @acsnano showed significant differences in systemic persistence of nano-lipids and spike mRNA between Moderna and Pfizer mRNA COVID vaccines!

Unlike what @washingtonpost & @bylenasun attempt to promote Demetre Daskalakis is NOT a ‘warrior’ of public health & science but part of the cult that tarnished any trust in public health!

The truth is that he actively tried to sabotage the scientific work of ACIP & the COVID Immunization Workgroup!

He worked hard to block discussions on any safety & efficacy issue related to potential contaminants in the COVID vaccines, their prolonged immunological effects (IgG4 class switch), the impact of documented frame shifting (production of unintended antigens) and prolonged vaccine injuries.

We should all be thankful that is not anymore in position of power!

In Ontario Canada Hep B vaccine birth dose is offered to babies of infected mothers or with special risk factors. All other children are vaccinated at grade 7 (age 12).

When ACIP recommended similar policy @nytimes & @apoorva_nyc voice the scare narrative of disaster.

And guess what in Ontario they believe the science that indicates that Hep B is transmitted through blood exchange and not through casual contacts…

Whenever data don’t support the narrative, they use data-free scare models!

Yet another @nytimes hit piece citing @AnnalsofIM simulation study, arguing that postponing Hepatitis B birth dose for babies of mothers who are tested negative to Hep B will cause significant harm..

Looks more like a planned hit piece on the new (stayed) ACIP and @SecKennedy than serious science.

Very easy to uncover the grossly biased model’s assumptions:

1) Ignore the fact that the recommendation to postpone birth dose applied only to women who are tested negative (not ones not tested).

2) Assuming that the newly recommended policy by ACIP of shared decision making will lead to only 50 percent vaccination rate.

3) Assuming community infection prevalence and horizontal infection rates grossly unrealistic to the vast majority of US households/families.

What the study does not do is to validate the model against real data from the many developed countries that don’t have birth dose, including parts of Canada. Data-free models can give you any results you wish to have…

Equally importantly the model assumes no harm from giving a baby medical intervention on the first day of life…
