Key Change in Genetics of SARS-CoV-2 Evolved to Counter Weakness Caused by the Virus’ Initial Mutation that Enabled Its Spread
Johns Hopkins Medicine

Researchers at Johns Hopkins Medicine say their new studies suggest that the first pandemic-accelerating mutation in the SARS-CoV-2 virus, which causes COVID-19, evolved as a way to correct vulnerabilities caused by the mutation that started the SARS-CoV-2 pandemic.

COVID-19 vaccine’s effectiveness diminishes with age, research shows
UT Southwestern Medical Center

The Pfizer-BioNTech COVID-19 vaccine limits transmission, hospitalization, and death from COVID-19 even among patients infected by variants of the virus, but the effectiveness of antibodies it generates diminishes as patients get older, according to a study by UT Southwestern researchers.

Investigating COVID-19 deaths for children and young people
PLOS

A new study conducted in England shows that the risk of death due to COVID-19 remains very low for children and young people, and most deaths occur in those with underlying health conditions. Marta Bertran of the UK Health Security Agency, London, and colleagues present these findings on November 8th in the open access journal PLOS Medicine.

How a SARS-CoV-2 Virus Protein Damages the Heart
University of Maryland School of Medicine

Researchers at the University of Maryland School of Medicine’s (UMSOM) Center for Precision Disease Modeling identified how a specific protein in SARS-CoV-2, the virus responsible for COVID-19, damages heart tissue. They then used a drug to reverse the toxic effects of that protein on the heart.

Other SARS-CoV-2 Proteins are Important for Disease Severity, Aside from the Spike
University of Maryland School of Medicine

University of Maryland School of Medicine researchers have identified how multiple genes of SARS-CoV-2 affect disease severity, which could lead to new ways in how we develop future vaccines or develop newer treatments. The genes control the immune system of the host, contributing to how fiercely the body responds to a COVID-19 infection.

New Data Shows COVID-19 Vaccine Does Not Raise Stroke Risk
Cedars-Sinai

Newly compiled data evaluated by researchers in the Department of Neurology and the Smidt Heart Institute at Cedars-Sinai shows that COVID-19 vaccines do not raise stroke risk--but that severe COVID-19 infection does. Physician-scientists hope this growing body of evidence, highlighted today in an editorial in the peer-reviewed journal Neurology, will ease the minds of individuals still hesitant to be vaccinated.

Patients with prior COVID may be twice as likely to have unhealthy endothelial cells that line the inside of the heart and blood vessels, according to newly published research from Houston Methodist. This finding offers a new clue in understanding COVID-19’s impact on cardiovascular health.

In a pair of related studies, UC San Diego researchers show that the origin of the COVID-19 pandemic was at a Chinese market and resulted from at least two instances of the SARS-CoV-2 virus jumping from live animal hosts to humans working or shopping there.

University of Utah Health

An international team of 18 researchers have determined that the earliest cases of COVID-19 in humans arose at a wholesale fish market in Wuhan China in December, 2019. They linked these cases to bats, foxes and other live mammals infected with the virus sold in the market either for consumption as meat or for their fur.

Pfizer-BioNTech and AstraZeneca vaccines offer high protection against severe COVID-19, 6 months after second doses, finds study of over 7 million adults
University of Bristol

Protection against severe COVID-19 by two doses of Pfizer-BioNTech and AstraZeneca COVID-19 vaccines remained high up to six months after second doses, finds new research which analysed NHS health record data on over seven million adults. Reassuringly, the University of Bristol-led study published in The BMJ today [July 20], found protection in older adults aged over 65 years, and in clinically vulnerable adults.

COVID-19 Vaccination in Pregnancy Helps Protect Infants from Needing Hospital Care for COVID-19
Ann and Robert H. Lurie Children's Hospital of Chicago

In a new study sponsored by the Centers for Disease Control and Prevention and published in the New England Journal of Medicine, researchers provide additional evidence that COVID-19 vaccination during pregnancy helps protect babies younger than 6 months from being hospitalized due to COVID-19. The risk of COVID-19 hospitalization among babies was reduced by about 80 percent during the Delta wave (July 1–December 18, 2021) and 40 percent during the Omicron wave (December 19–March 8, 2022).

Scientists at La Jolla Institute for Immunology (LJI) have found that four COVID-19 vaccines (Pfizer-BioNTech, Moderna, J&J/Janssen, and Novavax) prompt the body to make effective, long-lasting T cells against SARS-CoV-2. These T cells can recognize SARS-CoV-2 Variants of Concern, including Delta and Omicron.
