Viral Loads Similar Between Vaccinated and Unvaccinated People
A new study from the University of California, Davis, Genome Center, UC San Francisco and the Chan Zuckerberg Biohub shows no significant difference in viral load between vaccinated and unvaccinated people who tested positive for the delta variant of SARS-CoV-2. It also found no significant difference between infected people with or without symptoms.

Federal law prohibits employers and others from requiring vaccination with a Covid-19 vaccine distributed under an EUA
As decision-makers at organizations decide on their Covid-19 vaccination policy, they should be careful to not let this passion lead the organization to run afoul of the law.
Exclusive: The federal government paid hundreds of media companies to advertise the COVID-19 vaccines while those same outlets provided positive coverage of the vaccines
In response to a FOIA request filed by TheBlaze, HHS revealed that it purchased advertising from major news networks including ABC, CBS, and NBC, as well as cable TV news stations Fox News, CNN, and MSNBC, legacy media publications including the New York Post, the Los Angeles Times, and the Washingt...
Myocarditis and Pericarditis After Vaccination for COVID-19
This study investigates the incidence of myocarditis and pericarditis emergency department or inpatient hospital encounters before COVID-19 vaccine availability (January 2019–January 2021) and during a COVID-19 vaccination period (February-May 2021) in a large US health care system.
The mRNA-LNP platform's lipid nanoparticle component used in preclinical vaccine studies is highly inflammatory
The synthetic ionizable lipid in the Pfizer SARS-CoV-2 vaccine has been speculated to have approximately 20–30 days of half-life in humans (Comirnaty, 2021). Whether the long-term presence of ionizable lipid could lead to low levels of chronic inflammation and immune exhaustion (Wherry and Kurachi, 2015) remain to be determined.
Annual Summary of Vital Statistics: Trends in the Health of Americans During the 20th Century
The overall improvement in the health of Americans over the 20th century is best exemplified by dramatic changes in 2 trends: 1) the age-adjusted death rate declined by about 74%, while 2) life expectancy increased 56%. Leading causes of death shifted from infectious to chronic diseases. In 1900, infectious respiratory...

Single vs Repeated SARS-CoV-2 Rapid Antigen Testing Among Asymptomatic People in the Workplace
This comparative effectiveness research study assesses the accuracy of single vs repeated antigen testing for diagnosis of COVID-19 among asymptomatic individuals in a workplace setting.
Due to the fast global spreading of the Severe Acute Respiratory Syndrome Coronavirus – 2 (SARS-CoV-2), prevention and treatment options are direly needed in order to control infection-related morbidity, mortality, and economic losses. Although drug and inactivated and attenuated virus vaccine development can require significant amounts of time and resources, DNA and RNA vaccines offer a quick, simple, and cheap treatment alternative, even when produced on a large scale. The spike protein, which has been shown as the most antigenic SARS-CoV-2 protein, has been widely selected as the target of choice for DNA/RNA vaccines. Vaccination campaigns have reported high vaccination rates and protection, but numerous unintended effects, ranging from muscle pain to death, have led to concerns about the safety of RNA/DNA vaccines. In parallel to these studies, several open reading frames (ORFs) have been found to be overlapping SARS-CoV-2 accessory genes, two of which, ORF2b and ORF-Sh, overlap the spike protein sequence. Thus, the presence of these, and potentially other ORFs on SARS-CoV-2 DNA/RNA vaccines, could lead to the translation of undesired proteins during vaccination. Herein, we discuss the translation of overlapping genes in connection with DNA/RNA vaccines. Two mRNA vaccine spike protein sequences, which have been made publicly-available, were compared to the wild-type sequence in order to uncover possible differences in putative overlapping ORFs. Notably, the Moderna mRN...
