A Novel STING Agonist-Adjuvanted Pan-Sarbecovirus Vaccine Elicits Potent and Durable Neutralizing Antibody and T Cell Responses in Mice, Rabbits and NHPs

Researchers discovered a new STING agonist, CF501, and found that CF501-adjuvanted RBD-Fc vaccine elicited significantly stronger neutralizing antibody and T cell responses than Alum- and cGAMP-adjuvanted RBD-Fc in mice.

The Pandemic’s True Death Toll: Millions More than Official Counts

On 1 November, the global death toll from the COVID-19 pandemic passed 5 million, official data suggested. It has now reached 5.5 million. But that figure is a significant underestimate. Records of excess mortality — a metric that involves comparing all deaths recorded with those expected to occur — show many more people than this have died in the pandemic.

Single-Dose SARS-CoV-2 Vaccinations with Either BNT162b2 or AZD1222 Induce Disparate Th1 Responses and IgA Production

Investigators compared the early immune responses against AZD1222 and BNT162b2. SARS-CoV-2 seronegative participants received a single dose of either vaccine and were analyzed for immune cell, effector T cell, and antibody dynamics.

Hemagglutinin-Based DNA Vaccines Containing Trimeric Self-Assembling Nanoparticles Confer Protection against Influenza

Aiming to develop an effective vaccine with rapid production, robust immunogenicity, and high protective efficiency, a DNA vaccine was designed by fusing influenza virus hemagglutinin (HA) with self-assembled ferritin nanoparticles, denoted as HA-F.

SARS-CoV-2 Infections in Children: Understanding Diverse Outcomes

The author discusses our current understanding of SARS-CoV-2 infections in children and hypothesize that a life history and energy allocation perspective might offer an additional explanation to mild infections, viral dynamics and the higher incidence of rare multisystem inflammatory syndromes in children and young people.
