The synthesis of radiolabeled [25-C]-siamenoside I following a synthetic route developed using unlabeled materials is disclosed. The synthesis features an early stage labeling of the mogrol's C25 an oxidative cleavage-reconstruction strategy and regioselective glycosylations directed by protecting group manipulations. This route provided access to adequate amounts of [25-C]-siamenoside I for ADME and PK studies.

We established a multi-country hospital network to measure the SARS-CoV-2 incidence and effectiveness of COVID-19 vaccines among HCWs against laboratory-confirmed SARS-CoV-2 infection. HCWs from 19 hospitals in 10 countries participated in a dynamic prospective cohort study, providing samples for SARS-CoV-2 testing at enrolment and during weekly/fortnightly follow-up.

- * The overall vaccine effectiveness (VE) was found to be 49%, with higher effectiveness of 69% during the first month and declining to 40% by about 2-3 months after vaccination.
- * Notably, the vaccine showed over 70% effectiveness in protecting older adults (65 years and older) within the first month after receiving the shot.
Article Synopsis
- The CDC and ACIP endorse COVID-19 vaccination for patients with inborn errors of immunity (IEI), but there's limited knowledge on its safety and impact on infection severity in these patients.
- A study involving a registry of 1,245 IEI patients across 24 countries was conducted to gather data on vaccination frequency, safety, and effectiveness, revealing that 64.7% were vaccinated, primarily with mRNA vaccines.
- Results showed that vaccinated patients had significantly lower hospitalization and ICU admission rates when infected with COVID-19, indicating that vaccination is both safe and effective in reducing the severity of the disease in IEI patients.
