NewsResearchers advise strengthening immunity against COVID-19 in people with cancer
Researchers who led a study on the effectiveness of vaccines against COVID-19 among cancer patients in Catalonia, have recommended administering additional doses of the vaccine among this risk population.

NewsScientists uncover risk factors for long Covid
A study has found that people with a milder Covid-19 infection—including those who were vaccinated against SARS-CoV-2 and those who were infected with an Omicron variant—were more likely to recover quickly.

NewsMothers have lower risk of caesarean births after COVID vaccination
Pregnant women who have been vaccinated against Covid-19 are less likely to have a caesarean section or experience hypertension, according to a study.

NewsIntranasal COVID-19 vaccine headed to clinical trials
CyanVac will sponsor a randomized, double-blind Phase 2b study to compare the efficacy and safety of CVXGA, its intranasal vaccine candidate designed to protect against COVID-19, against an FDA-approved mRNA-based COVID-19 vaccine.

NewsNew study helps explain how elderly individuals react differently to COVID-19 than young people
A new study suggests that a suppressed immune landscape is a key driver of age-associated endothelial dysfunction during COVID-19.

NewsFeeling rough after your COVID shot? That means it’s working!
Side effects of the Covid vaccine may include tiredness, muscle and joint pain, chills, headache, fever or nausea, but a new study finds that the symptoms indicate a robust immune response that is likely to lessen the chances of infection.

NewsStudy finds no association between COVID-19 vaccines and stillbirths
In a new study funded by the U.S. Centers for Disease Control and Prevention, researchers found “no association between COVID-19 vaccination and stillbirth”.

NewsVirus that causes COVID-19 can remain in sperm for 110 days after infection
Researchers detected SARS-CoV-2 in male reproductive cells under the microscope even when PCR testing failed to detect the virus in semen. The discovery serves as a warning of possible implications for natural conception and assisted reproduction.

NewsVaccine approach offers promise to induce longer-lasting protective immunity against COVID-19
A scientific team has engineered a COVID-19 vaccine that induced – in pre-clinical models – very long-lasting, protective immunity against SARS-CoV-2 virus with a single-shot immunisation.

NewsOral nucleoside antiviral is progressing toward future pandemic preparedness
Oral obeldesivir has been shown to reduce disease severity in mice infected with one of several different coronaviruses, including SARS-CoV-2 (which causes COVID-19), SARS-CoV and MERS-CoV.

NewsPathway into cell influences the outcome of SARS-CoV-2 infection
The protein TMPRSS2 acts as a helper to bring the virus into the cell via the receptor ACE2. This TMPRSS2-mediated uptake significantly alters the immune response of the host cells and drives the evolution of the virus, a new study shows.
-
NewsScientists develop new nanoscale way to see viruses in action
A new, nano-scale look at how the SARS-CoV-2 virus replicates in cells may offer greater precision in drug development, scientists report.

NewsStatisticians call for rigour and transparency in the evaluation of diagnostic tests
Recommendations designed to reframe the evaluation of in vitro diagnostic tests have been published - intended to help prevent future scenarios in which IVDs are marketed widely, but later attract serious concerns about the standards applied to their evaluation.

NewsKnowledge is a factor in closing black-white COVID-19 vaccination gap
Early in the Covid-19 pandemic, Black Americans were more hesitant to take the Covid-19 vaccine than were White Americans. As the pandemic went on, however, the disparity in vaccination rates between Black and White adults declined. Source: Baltimore County Government People queueing to be vaccinated, 23 December 2020 ...

NewsNew electrostatic sampler boosts indoor virus detection speed
Researchers have developed a groundbreaking electrostatic air sampler that enhances the rapid monitoring of airborne influenza and coronavirus.

NewsStudy shows N95 masks near-perfect at blocking escape of airborne COVID-19
In a head-to-head comparison of masks worn by people with active COVID-19, the inexpensive ‘duckbill’ N95 came out on top, stopping 98% of COVID-19 particles in the breath of infected people from escaping into the air.
-
NewsEffectiveness of updated COVID-19 vaccines wanes moderately over time, is lower against currently circulating variants
New research shows boosters targeting omicron subvariants of SARS-CoV-2 are still providing reasonably durable protection against infection, hospitalization and death from COVID-19, but are less protective against the JN.1 strain.
-
NewsResearchers take step toward development of universal COVID-19 antibodies
Scientists have developed a promising new human monoclonal antibody that appears a step closer to a universal antibody cocktail that works against all strains of SARS-CoV-2.
-
NewsRisk of death from COVID-19 lessens, but infection still can cause issues 3 years later
A new study also shows that patients hospitalized within 30 days after infection face a 29% higher death risk in the third year compared with those not infected.

NewsScientists probe missing microbes in infants and children in the COVID-19 pandemic
Researchers conducted a comparative analysis of the gut microbiome of 1,126 children and infants during the COVID-19 pandemic in the Beijing area, revealing the variation of their gut microbiome.
