Abstract: Purpose: The risk of myopericarditis following COVID-19 booster vaccination has not been extensively evaluated. We provide a timely case ascertainment of myocarditis following COVID-19 booster vaccine in individuals age 18-39 years from an integrated health system. Methods: We studied a cohort of 65,785 Kaiser Permanente (KP) Northwest Health Plan members aged 18-39 years who received a COVID-19 vaccine booster at least 5 months following completion of the primary series. We identified cases of myopericarditis by searching the electronic health record for the National Center for Health Statistics (NCHS) text label for myocarditis or pericarditis diagnosis codes in all inpatient and outpatient encounters through January 18th 2022. The cohort was followed for 21 days after their booster. We excluded anyone with a documented diagnosis of myocarditis or pericarditis before their first COVID-19 vaccination. Two physicians independently reviewed the identified patient records and applied the CDC myocarditis and pericarditis surveillance case definition to classify records as confirmed, probable or excluded based on the prior published definition. Results: Our method identified 6 patients who met the confirmed or probable CDC case definition for acute myocarditis or pericarditis within 21 days of COVID-19 booster dose among 65,785 eligible members. Four cases occurred in 27,253 men. Overall, we estimated 9.1 cases (exact 95% CI 3.4 to 19.9) of post-booster myopericarditis per 100,000 booster doses given. In men, we estimated 14.7 cases (exact 95% CI 4.0 to 37.6) per 100,000 booster doses given. Conclusion: We identified a rate of 9.1 cases of myopericarditis per 100,000 COVID-19 booster doses which is higher than prior estimates reported by the Vaccine Adverse Event Reporting System (VAERS). Myopericarditis occurs following COVID-19 booster vaccine and may be underreported by current surveillance methods. High sensitivity of these case estimates is essential when modeling risk and benefit for sequential COVID-19 vaccinations for the general population. ### Competing Interest Statement The authors have declared no competing interest. ### Funding Statement This study did not receive any funding ### Author Declarations I confirm all relevant ethical guidelines have been followed, and any necessary IRB and/or ethics committee approvals have been obtained.

Mass youth hospitalizations, COVID-induced diabetes, and other myths from the brave new world of science as political propaganda

This study uses serologic testing to characterize natural immunity and the long-term durability of SARS-CoV-2 antibodies among unvaccinated US adults by history of COVID-19 infection.

A link to the vaccines is not certain, and investigations are underway in some reported cases. (NYT article from before the media consortium agreement)

Risk of Myopericarditis following COVID-19 mRNA vaccination in a Large Integrated Health System: A Comparison of Completeness and Timeliness of Two Methods "The true incidence of myopericarditis is markedly higher than the incidence reported to US advisory committees."

Brain fog, headaches, blood pressure swings are being probed by NIH and other researchers

The importance of understanding SARS-CoV-2 evolution cannot be overlooked. Recent studies confirm that natural selection is the dominating mechanism of SARS-CoV-2 evolution, which favors mutations that strengthen viral infectivity. Here, we demonstrate that vaccine-breakthrough or antibody-resistant mutations provide a new mechanism of viral evolution. Specifically, vaccine-resistant mutation Y449S in the spike (S) protein receptor-binding domain, which occurred in co-mutations Y449S and N501Y, has reduced infectivity compared to that of the original SARS-CoV-2 but can disrupt existing antibodies that neutralize the virus. By tracking the evolutionary trajectories of vaccine-resistant mutations in more than 2.2 million SARS-CoV-2 genomes, we reveal that the occurrence and frequency of vaccine-resistant mutations correlate strongly with the vaccination rates in Europe and America. We anticipate that as a complementary transmission pathway, vaccine-breakthrough or antibody-resistant mutations, like those in Omicron, will become a dominating mechanism of SARS-CoV-2 evolution when most of the world’s population is either vaccinated or infected. Our study sheds light on SARS-CoV-2 evolution and transmission and enables the design of the next-generation mutation-proof vaccines and antibody drugs.

It is not normal for young athletes to suffer cardiac arrest or death while playing sport, but most of these come shortly after a COVID shot.

rGO was able to be detected and monitored in the brain over time provided by a novel application for MALDI-MSI and could be a useful tool for treating a variety of brain disorders that are normally unresponsive to conventional treatment because of BBB impermeability.

We report two cases of patients developing COVID-19 shortly after CoronaVac vaccination in which VADE is likely. We recommend that current vaccination strategies consider the measurement of neutralizing antibody titer as a guide in ensuring the safest strategy for mass immunization. Studies are need …

The specific and significant COVID-19 risk of ADE should have been and should be prominently and independently disclosed to research subjects currently in vaccine trials, as well as those being recruited for the trials and future patients after vaccine approval, in order to meet the medical ethics s …

We are a large and ever growing group of Americans who were previously healthy and have been seriously injured by the COVID vaccines.

Mayor Eric Adams admitted that vaccine mandates don’t work, yet is still going ahead with firing city workers who refuse to prove they got the shot.

The agency has withheld critical data on boosters, hospitalizations and, until recently, wastewater analyses.

The document captures the struggle of the nation’s top public health agency to persuade the public to embrace vaccination and prevention measures, including mask-wearing, as cases surge across the United States and new research suggests vaccinated people can spread the virus.

by Dr. John D. Flack I joined Beecham Research Laboratories in 1970 as a pharmacologist/endocrinologist charged with discovering new anti-fertility ‘drugs’. My team came close but ultimately failed in this endeavor but as is the norm in the discovery of pharmaceuticals we made the serendipitous discovery of an anti-inflammatory compound which became a very successful … Why Weren’t These Vaccines Put Through the Proper Safety Trials For Gene Technology, Asks a Former Pharmaceutical Research Scientist Read More »

Human antibody responses to SARS-CoV-2 differ between vaccination and infection, with mRNA vaccination inducing more productive lymph node GC responses and several vaccine types stimulating IgG antibodies capable of recognizing a broader range of viral variants.
