Updated results on coronavirus vaccination effectiveness

Several weeks following the publication of the large real-world COVID-19 vaccine effectiveness study by the Clalit Research Institute in Collaboration with Harvard University in the New England Journal of Medicine (NEJM), additional results focusing on vaccine effectiveness in specific sub-populations have now been published.

New COVID-19 vaccine may offer broad protection from coronaviruses

A COVID-19 vaccine that could provide protection against existing and future strains of the COVID-19 coronavirus, and other coronaviruses, and cost about $1 a dose has shown promising results in early animal testing.

Vaccines created by UVA Health's Steven L. Zeichner, MD, PhD, and Virginia Tech's Xiang-Jin Meng, MD, PhD, prevented pigs from being becoming ill with a pig model coronavirus, porcine epidemic diarrhea virus (PEDV).

SARS-CoV-2: New findings on the persistence of neutralizing antibodies

It is an open question to what extent protection against reinfection persists after overcoming a SARS-CoV-2 infection. The "Rhineland Study", a population-based study conducted by DZNE in the Bonn area, is now providing new findings in this regard. Blood samples taken last year indicate that an important component of immunity - the levels of specific neutralizing antibodies against the coronavirus - had dropped in

B.1.1.7. variant more transmissible, does not increase severity, Lancet studies suggest

Two new studies, published in The Lancet Infectious Diseases and The Lancet Public Health, found no evidence that people with the B.1.1.7. variant experience worse symptoms or a heightened risk of developing long COVID compared with those infected with a different COVID-19 strain. However, viral load and R number were higher for B.1.1.7., adding to growing evidence that it is more transmissible than the first strain detected in Wuhan, China, in December 2019.

COVID-19 causes 'unexpected' cellular response in the lungs

New insights into the immune response to SARS-CoV-2 infections could bring better treatments for COVID-19 cases.

An international team of researchers unexpectedly found that a biochemical pathway, known as the immune complement system, is triggered in lung cells by the virus, which might explain why the disease is so difficult to treat.

Prioritizing who gets vaccinated for COVID-19 saves lives

Waiting for your turn can be frustrating, especially when it comes to COVID-19 vaccinations. But prioritizing who receives the limited supply of vaccines available saves lives and reduces spread of infection, according to a study published in the journal PNAS from the University of California, Davis.

Anti-inflammatory drug protects against lethal inflammation from COVID-19 in animal models

Mount Sinai researchers have found that a widely available and inexpensive drug targeting inflammatory genes has reduced morbidity and mortality in mice infected with SARS-CoV-2, the virus that causes COVID-19. In a study published today in the journal Cell, the team reported that the drug, Topotecan (TPT), inhibited the expression of inflammatory genes in the lungs of mice as late as four days after infection, a finding with potential implications for treatment of humans.
