A country's efforts toward creating an advanced practice nurse in public health.

Aim: The study goal was to inform the creation of a blueprint for an advanced practice nurse (APN) in public health.

Background: No internationally accepted standard for an APN in public health exists. Activities of public health nurses (PHN) traditionally have centered on health promotion and disease prevention, but many have added other population-based activities such as chronic and acute disease treatment.

Correlates of protection against COVID-19 infection and intensity of symptomatic disease in vaccinated individuals exposed to SARS-CoV-2 in households in Israel (ICoFS): a prospective cohort study.

Background: Identifying COVID-19 correlates of protection and immunity thresholds is important for policy makers and vaccine development. We aimed to identify correlates of protection of BNT162b2 (Pfizer-BioNTech) vaccination against COVID-19.

Methods: In this prospective cohort study, households within a radius of 40 km of the Sheba Medical Center in Israel in which a new SARS-CoV-2 infection (defined as the index case) was detected within the previous 24 h were approached between July 25 and Nov 15, 2021.
