by Gertrud U. Rey The shingles vaccine is highly effective at preventing shingles, a painful rash caused by reactivation of varicella-zoster virus (VZV) – the herpes virus that also causes chickenpox. But what if this vaccine also prevented dementia? New data suggest that it just might. The authors of a recent multinational collaborative research study …
by Gertrud U. Rey The number of measles cases is steadily increasing across the United States, especially in areas with low vaccination rates. Instead of recommending that children be vaccinated with the measles, mumps, and rubella (MMR) vaccine, US Health and Human Services Secretary Robert F. Kennedy Jr. continues to promote ideas that are rooted …
by Gertrud U. Rey On February 7, 2025, the world lost Dickson Despommier, a formidable parasitologist, gifted storyteller, and original co-host of the podcast This Week in Virology. Being a life-long learner, Dickson developed a keen interest in medical ecology, an interdisciplinary field that investigates how our ever-changing environment impacts human health. In his book …
When the B.1.1.7 variant of SARS-CoV-2 was first detected in the UK in December 2020 it was accompanied by unsubstantiated claims of increased transmissibility and virulence. The results of a hospital-based study in London reveals no association of the variant with severe disease in this cohort. In a note published by NERVTAG on 21 January …
In our quest to stop the COVID-19 pandemic by vaccination, we have been myopically focussed on inducing antibodies against the spike protein. As variants of SARS-CoV-2 have emerged that reduce the ability of such antibodies to block infection, concern has arisen that we will not be able to halt the disease. Such concerns appear to …
In recent months variants of SARS-CoV-2 have been detected that are unusual in that they have many more genome mutations than previously found. These have been called ‘variants of concern’ (VOC) as it has been suggested that the genome mutations might impact transmission, immune control, and virulence. Below I cover each of these issues separately. …
