MMR vaccine may protect against Covid-19, says study

WASHINGTON: The measles-mumps-rubella (MMR) vaccine may provide protection against Covid-19, according to a study that could also explain why children have a much lower case rate and death rate of the disease than adults. The MMR vaccine has been theorised to provide protection against Covid-19, and now the study, published in the journal mBio, provides further proof of this by showing that mumps IgG titers, or levels of IgG antibody, are inversely correlated with severity in recovered Covid-19 patients previously vaccinated with the MMR II vaccine. MMR II contains the…

Coronavirus infection may offer protection from reinfection for this long; read here | Health News

London: A new UK study has suggested that individuals who have previously contracted COVID-19 are highly unlikely to contract the illness again for at least six months following their first infection. The study, done as part of a major collaboration between the University of Oxford and Oxford University Hospitals (OUH) NHS Foundation Trust involving frontline healthcare workers, suggests that most people are unlikely to get COVID-19 again if they have already had it in the previous six months. “This is really good news because we can be confident that, at…

Three kids of COVID-19 positive parents in Australia develop antibodies without being coronavirus infected | Health News

Melbourne: In an unusual case, three kids of COVID-19 positive parents in Melbourne (Australia) have developed antibodies without ever being infected with the coronavirus.  The article published in the ‘Nature Communications’ journal said that the data indicates that children can mount an immune response to SARS-CoV-2 without virological confirmation of infection, raising the possibility that immunity in children can prevent the establishment of COVID-19 infection. The authors described clinical features, virology, longitudinal cellular, and cytokine immune profile, SARS-CoV-2-specific serology and salivary antibody responses in a family of two parents with…

E-cigarette users may have increased susceptibility to coronavirus | Health News

Washington: In a controlled study of smokers, nonsmokers, and e-cigarette users, University of North Carolina School of Medicine researchers found that e-cigarette users exhibited significantly altered immune responses to a model of influenza virus infection, suggesting increased susceptibility to disease. The findings, published in the American Journal of Respiratory Cell and Molecular Biology, show that vaping changes the expression of genes and production of proteins in respiratory cells, as well as altering virus-specific antibody production. “In many of the study participants, we observed more changes to the immune response in…

Can first COVID-19 vaccines bring herd immunity? Experts have doubts | Health News

LONDON: Governments and officials are voicing hopes that COVID-19 vaccines could bring “herd immunity”, with some calculating that immunising just two-thirds of a population could halt the pandemic disease and help protect whole communities or nations. But the concept comes with caveats and big demands of what vaccines might be capable of preventing. Some experts say such expectations are misplaced. For a start, figuring out what`s needed to achieve herd immunity with coronavirus vaccines involves a range of factors, several of which are unknown. What is the rate of the…
