Producing more mRNA COVID vaccines could save 1.5M lives in low/middle-income countries

In a recent study posted to the medRxiv* preprint server, a team of researchers from the United States estimated the benefits of scaling up coronavirus disease 2019 (COVID-19) vaccination in the low- and lower-middle-income countries (LIC/LMICs) amid the global spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant using economic and epidemiological models linearized with public data of COVID-19 vaccinations and deaths.

SpaceX employee study estimates odds ratio for SARS-CoV-2 reinfection

Researchers evaluate the risk of SARS-CoV-2 infection and reinfection over time between April 2020 and February 2021.

14 Feb 2022

Development of multivalent next-generation vaccine strategy against ancestral SARS-CoV-2 and emerging variants

A recent study demonstrated that intranasal (i.n.) delivery of COVID-19 vaccine in murine models elicits greater immune responses against the wildtype SARS-CoV-2 and its variants.

Study demonstrates associations between COVID-19 symptom presentation and antibody assay reactivity

Researchers tested convalescent sera from individuals who had recovered from SARS-CoV-2 infection to demonstrate an association between antibody response and reported COVID-19 symptoms.

14 Feb 2022

Study shows expression of viral proteases may be used to quantitate SARS-CoV-2 infected cells

A new study describes a new method to quantify SARS-CoV-2 infection, which is much simpler and faster compared to existing methods.

Real world evidence on acquired immunity from vaccines and SARS-CoV-2 infection

Researchers assess the incidence of SARS-CoV-2 breakthrough cases and reinfections among unvaccinated and vaccinated individuals.

13 Feb 2022

Study provides evidence for spike protein-independent attenuation of SARS-CoV-2 Omicron variant

A new study provided the structural basis for a robust interaction between the receptor-binding domain of the SARS-CoV-2 Omicron spike protein and mouse ACE2.

CDC study first to show waning immunity after third dose of mRNA COVID-19 vaccine

A nationwide study from the U.S. Centers for Disease Control and Prevention is the first to show that immunity against severe COVID-19 disease begins to wane 4 months after receipt of the third dose of an mRNA vaccine (Pfizer or Moderna).

90 minutes of exercise after vaccination may provide an extra immune boost

Researchers at Iowa State University found 90 minutes of mild- to moderate-intensity exercise directly after a flu or COVID-19 vaccine may provide an extra immune boost.

12 Feb 2022

Pharmacological manipulation could restore microglia function after exposure to industrial toxin in utero

New research shows that exposure to the industrial byproduct TCDD in utero could cause the brain's immune system to go array later in life, damaging important brain circuits, and potentially giving rise to neurodevelopmental disorders, such as autism and ADHD.
