New study sheds light on the biological properties of new COVID variant Pirola

Despite the end of the pandemic, COVID-19 continues to pose a serious health threat. Most individuals have established robust immune protection and do not develop severe disease but the infection can still lead to marked and sometimes long-lasting disease symptoms.

Real-world study tracks vaccine's power to protect kids from Delta and Omicron variants

Children and adolescents who received one of the main COVID-19 vaccines were significantly protected from the illness and showed no increased signs of cardiac complications compared to young people who were not vaccinated, according to a new real-world study led by researchers from the Perelman School of Medicine at the University of Pennsylvania and Children's Hospital of Philadelphia (CHOP).

SARS-CoV-2 BA.2.86 shows increased lung targeting despite vaccine effectiveness

New research shows that the recently emerged BA.2.86 omicron subvariant of the virus that causes COVID-19 can be neutralized by bivalent mRNA vaccine-induced antibodies in the blood, which explains why this variant did not cause a widespread surge as previously feared.
