The Lancet – Singapore offered the BNT162b2 vaccine (tozinameran; Pfizer-BioNTech) to adolescents aged 12–17 years in May 18, 2021, and extended booster vaccines to this group in Jan 21, 2022. Literature on the effectiveness of primary series and booster vaccination among adolescents is scarce outside of Europe and North America. We aimed to determine primary […]

What comes after Omicron? New variants are emerging.
National Geographic – Infections over the last three months have been dominated by new sublineages of Omicron: BA.2, BA.2.12.1, BA.4., and BA.5. In the U.K., symptomatic infections have steadily increased since August 27—the day they hit lowest level this year—according to the ZOE COVID-19 study, an App-based project in which patients enter their symptoms on their […]

Mental Health During the COVID-19 Pandemic
NIH – Both SARS-CoV-2 and the COVID-19 pandemic have significantly affected the mental health of adults and children. In a 2021 study, nearly half of Americans surveyed reported recent symptoms of an anxiety or depressive disorder, and 10% of respondents felt their mental health needs were not being met. Rates of anxiety, depression, and substance […]

Repurposing existing drugs to fight new COVID-19 variants
Michigan State University – MSU researchers are using big data and AI to identify current drugs that could be applied to treat new COVID-19 variants. Finding new ways to treat the novel coronavirus and its ever-changing variants has been a challenge for researchers, especially when the traditional drug development and discovery process can take years. […]

JAMA – Question Is SARS-CoV-2 seropositivity associated with symptoms of myalgic encephalomyelitis and/or chronic fatigue syndrome (ME/CFS) in children and adolescents? Findings This cross-sectional study of hospital-based SARS-CoV-2 seroprevalence surveys in Germany compared seropositive and seronegative children and adolescents and identified an excess of possible ME/CFS symptoms with serological evidence of preceding SARS-CoV-2 infection. This association almost […]

Remdesivir resistance in transplant recipients with persistent COVID-19
Clinical Infectious Diseases – New mutations conferring resistance to SARS-CoV-2 therapeutics have important clinical implications. We describe the first cases of an independently acquired V792I RNA-dependent RNA polymerase mutation developing in renal transplant recipients after remdesivir exposure. Our work underscores the need for augmented efforts to identify concerning mutations and address their clinical implications. Download […]

SARS-CoV-2 mutation leads to resistance to remdesivir in 2 patients
CIDRAP – A report published yesterday in Clinical Infectious Diseases describes a new SARS-CoV-2 mutation that confers resistance to the COVID-19 antiviral drug remdesivir in two persistently infected kidney transplant recipients treated with immunosuppressive drugs. NYU researchers identified the V792I RNA-dependent 25 RNA polymerase mutation in the transplant patients, who were hospitalized and experienced life-threatening COVID-19 complications […]

Japan’s COVID herd immunity near 90% after Omicron wave, study says
Reuters – Japan’s population level immunity to COVID-19 has reached about 90% in major population areas after a recent Omicron wave, though that level of protection is likely to diminish in a matter of months, according to a study published on Tuesday.

Further humoral immunity evasion of emerging SARS-CoV-2 BA.4 and BA.5 subvariants
The Lancet – SARS-CoV-2 BA.4 and BA.5 lineages have been the dominant strains in most regions worldwide and are continuously gaining mutations in the receptor-binding domain. Multiple BA.4 and BA.5 subvariants with Arg346 mutations in the spike glycoprotein have been identified in various countries, such as BA.4.6, BF.7, BA.5.2.6, BA.4.1.9, and BE.1.2 harbouring Arg346Thr; BA.4.7 […]
