Study shows single dose of mRNA vaccine may suffice for those with prior SARS-CoV-2 infection

A recent study by researchers from Philadelphia, currently available on the medRxiv preprint server, shows that individuals with prior infection caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) exhibit substantial immune memory and develop a robust response to the first dose of an mRNA vaccine.

Computational analysis reveals why new SARS-CoV-2 variants bind better to human cells

All viruses mutate as they make copies of themselves to spread and thrive. SARS-CoV-2, the virus the causes COVID-19, is proving to be no different. There are currently more than 4,000 variants of COVID-19, which has already killed more than 2.7 million people worldwide during the pandemic.

Pfizer coronavirus vaccine found to be moderately less effective against South African variant

Ben-Gurion University of the Negev (BGU) researchers have found that the Pfizer Coronavirus vaccine is moderately less effective against the South African variant, but still neutralizes the British variant and the original SARS-CoV-2 strain.

Is T-cell receptor sequencing a reliable alternative to SARS-CoV-2 antibody testing?

Researchers in the United States have now demonstrated that T-cell receptor (TCR) sequencing might provide a reliable alternative to assessing infection in convalescent blood plasma, and may be applicable in the future for applying protective immunity to individuals.

Correlation of antibody titers with COVID-19 vaccine efficacy

In a new study the relationship between virus-neutralizing antibody and spike protein-binding IgG antibody levels is explored following vaccination by one of seven currently deployed vaccines. The findings support the use of antibody titers as correlates of protection for COVID-19 vaccines.

COVID-19 vaccines reduce virus transmission in healthcare worker case study

In a new study, the ability of COVID-19 vaccines to lessen transmission was examined in a large study of healthcare workers and their families, with promising results that indicate a substantially reduced rate of transmission from the vaccinated to the non-vaccinated.

A new COVID-19 candidate vaccine induces robust humoral and cellular immune responses in mice

A Korea-based company EyeGene Inc. has recently developed a liposome-based mRNA candidate vaccine against COVID-19, which contains full-length spike protein of the European variant (D614G) of SARS-CoV-2 as a vaccine antigen.

‘An Arm and a Leg’: In vaccinating Philadelphia, a mix of the good, the bad and the ugly

In Philadelphia, the good, the bad and the ugly have all been on vivid display in the covid vaccine rollout.

‘Press 1 for English’: Vaccination sign-ups prove daunting for speakers of other languages

In late February, a week after Virginia launched a centralized website and call center for covid-19 vaccine preregistration, Zowee Aquino alerted the state to a glitch that could prove fatal for non-English speakers trying to secure a shot.

Democrats eye Medicare negotiations to lower drug prices

Democrats, newly in control of Congress and the White House, are united behind an idea that Republican lawmakers and major drugmakers fiercely oppose: empowering the Department of Health and Human Services to negotiate the prices of brand-name drugs covered by Medicare.

Widening ideological gap in the U.S. may contribute to challenges in medical research

The lightning speed with which scientists developed and tested the COVID-19 vaccine is a true scientific triumph -- one that would not have been possible without the more than 70,000 volunteers who participated in clinical trials of the vaccine.

Single BNT162b2 mRNA dose induces humoral and T cell responses against mutated variants with a history of COVID-19

In a paper recently uploaded to the preprint server bioRxiv by Tauzin et al. (March 18th, 2021) the ability of a single dose of mRNA vaccine to induce humoral and T cell responses against mutated variants are demonstrated and found to be reinforced in individuals with a history of COVID-19.

Simple SARS-CoV-2 mutations allow escape from the majority of polyclonal antibodies

The group identified a single class of antibodies that target a particular epitope on the RBD of SARS-CoV-2, suggesting that the human polyclonal response to SARS-CoV-2 infection is dominated by a worryingly narrow range of antibodies that target an epitope undergoing rapid mutation.

B.1.1.7 SARS-CoV-2 variant significantly more dangerous

Now, researchers at the University of Exeter, the NHS Foundation Trust, report a significant increase in mortality risk due to the B.1.1.7 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant.

Researchers find the right dosing of an old anti-tuberculosis drug

A considerably higher dose of the anti-tuberculosis drug rifampicin is safe and can also lead to a shorter treatment for tuberculosis and less resistance.

AstraZeneca's COVID-19 vaccine protects against symptomatic disease

Results from a large clinical trial in the United States and South America indicate that AstraZeneca's COVID-19 vaccine, AZD1222, is well-tolerated and protects against symptomatic COVID-19 disease, including severe disease or hospitalization.

Some dream — others scheme — to find a vaccine before spring break

Hawaii, Florida, Seattle and the South of France are on the minds of New York City college students. Those are some of the destinations that undergrads mentioned when asked where they'd go for spring break, if they weren't grounded by Covid-19.

In America, Covid vaccine eligibility is a ‘crazy quilt’ of state rules

In North Carolina, the nation's leading tobacco producer, any adult who has smoked more than 100 cigarettes in their lifetime can now be vaccinated against Covid.

Could nanoparticle vaccines offer broad protection against sarbecoviruses?

To understand the ability of SARS-CoV-2 vaccine-elicited antibodies to neutralize and protect against emerging variants (that are pathogenic) and other sarbecoviruses, a large team of researchers studied immunity by receptor-binding domain nanoparticle vaccines. They showed that a clinical-stage multivalent SARS-CoV-2 receptor-binding domain nanoparticle vaccine (SARS-CoV-2 RBD-NP) protected mice from the SARS-CoV-2-induced disease.
