Prioritization of COVID-19 vaccines saves lives, reduces spread of infection

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 today in the journal PNAS from the University of California, Davis.

Higher B.1.1.7 transmission in households than other SARS-CoV-2 variants

Contact tracing data from a new preprint study on the medRxiv* preprint server provides further evidence that the B.1.1.7 variant — first reported in the United Kingdom — has a high transmission rate. The research, led by Birgitte Freiseleben de Blasio from the Norwegian Institute of Public Health and the University of Oslo in Norway, estimates B.1.1.7 has a 60% greater transmission within households than other severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants of concern.

Study finds CD8+ T cell responses detect all major SARS-CoV-2 variants

There have been concerns that several SARS-CoV-2 variants have mutations that allow them to evade the immune system. A new study published in the Open Forum Infectious Diseases suggests otherwise. Led by Aaron AR Tobian of Johns Hopkins University School of Medicine, results showed that except for one from the B.1.351 variant, CD8+ T cells showed a broad response to all SARS-CoV-2 variants.

Beating the pavement to vaccinate the underrepresented — and protect everyone

Leonor Garcia held her clipboard close to her chest and rapped on the car window with her knuckles. The driver was in one of dozens of cars lined up on a quiet stretch of road in Adelanto, California, a small city near the southwestern edge of the Mojave Desert.

Can asymptomatic COVID-19 confer long-term immunity?

Researchers examined the antibody responses in symptomatic and asymptomatic individuals recovered from COVID-19 to see if there was a discernable difference in their humoral immune responses and long-term protection from reinfection with SARS-CoV-2.

Researchers develop a recombinant SARS-CoV-2 receptor-binding domain trimer vaccine candidate

New research deals with the development of RBD trimer as a potent target for SARS-CoV-2 subunit vaccines. This study revealed the development of a trimeric RBD subunit vaccine candidate that could induce strong humoral and cellular immune responses in nonhuman primates (NHPs), namely, rhesus macaques.

Oxford-AstraZeneca vaccine effective against B.1.1.7 SARS-CoV-2 variant

Published in The Lancet, the study explores if the Oxford-AstraZeneca vaccine works well in protecting against the B.1.1.7 variant, otherwise known as the U.K. variant.

Antibody tests, even rapid finger pricks, are effective COVID-19 screening tools

New findings from a Michigan Medicine study reveal that antibody testing is predictive of prior COVID-19 infection, and rapid screening methods - even from finger pricks - are effective testing tools.

Risk of SARS-CoV-2 from reinfected individuals with previous infection or vaccination

A technical report recently published by the European Center for Disease Prevention and Control (ECDC) has summarized all available literature regarding the risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission from asymptomatic reinfected individuals with a history of SARS-CoV-2 infection or vaccination.

Male fetuses impair the maternal and placental immune response to SARS-CoV-2 infection in pregnancy, finds study

The ongoing COVID-19 pandemic, caused by SARS-CoV-2, is now established to be more likely to lead to symptomatic and serious illness in males relative to females. This may extend as far back as pregnancy, suggests a recent study.

Infliximab may hinder the effectiveness of some COVID-19 vaccines

A new study reports reduced vaccine efficacy following the use of a single COVID-19 vaccine dose in people who are on the immunosuppressive monoclonal antibody Infliximab.

Asymmetrical vaccine distribution could promote vaccine evading mutations in SARS-CoV-2

Researchers have investigated the ultimate influence of unequal vaccine distribution by mathematical modeling, revealing the critical role of fair distribution in future COVID-19 containment strategy.

NIAID researchers identify key player in the immune response to SARS-CoV-2

When variants of SARS-CoV-2 (the virus that causes COVID-19) emerged in late 2020, concern arose that they might elude protective immune responses generated by prior infection or vaccination, potentially making re-infection more likely or vaccination less effective.

Study of twins reveals differences in adaptive immunity towards SARS-CoV-2

Twins may look alike on the outside, but not so much on the inside. That's one takeaway from a new preprint study posted to the medRxiv server where Brazilian researchers observed different T-cell responses in two pairs of identical twins exposed to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). One twin who was reinfected with SARS-CoV-2 four months after had low recognition of CD4+ and CD8+ T-cell epitopes.

Single dose of Pfizer and Oxford vaccines shows 60% efficacy in elderly care home residents

A new study deals with the effect of two widely used vaccines in eliciting humoral immunity against the virus in this group. These are the Oxford/AstraZeneca viral-vectored vaccine (ChAdOx1 nCoV-19), and the Pfizer/BioNTech’s messenger RNA-based vaccine (BNT162b2). Both express the viral spike antigen, and both are currently being employed in the UK’s vaccination program.
