An estimate of Omicron’s fitness advantage

An estimate of Omicron’s fitness advantage

The persistent evolution of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causal agent of the coronavirus disease 2019 (COVID-19), has prolonged the current pandemic. This has led to the emergence of several SARS-CoV-2 variants, some of which have been classified as variants of concern (VOC) or variants of interest (VOI). These classifications are …

Obesity causes COVID vaccines to lose their efficacy more rapidly

Obesity causes COVID vaccines to lose their efficacy more rapidly

In a recent study posted to the medRxiv* pre-print server, researchers examined a clinical cohort of severely obese people vaccinated with coronavirus disease 2019 (COVID-19) vaccines to determine the relationship between an individual’s body mass index (BMI) and COVID-19-related hospitalization and mortality. They demonstrated that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine-induced humoral immunity …

Medication and lifestyle changes improve dizziness in pediatric lung-COVID patients

Medication and lifestyle changes improve dizziness in pediatric lung-COVID patients

Several persistent yet nonspecific symptoms have been reported in individuals who have previously recovered from infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This phenomenon has been referred to as long coronavirus disease 2019 (COVID-19), post-COVID syndrome, and post-acute sequelae of SARS-CoV-2 infection (PASC). Although no viral load is detected in these patients, …
