Development and evaluation of low-volume tests to detect and characterize antibodies to SARS-CoV-2.

Low-volume antibody assays can be used to track SARS-CoV-2 infection rates in settings where active testing for virus is limited and remote sampling is optimal. We developed 12 ELISAs detecting total or antibody isotypes to SARS-CoV-2 nucleocapsid, spike protein or its receptor binding domain (RBD), 3 anti-RBD isotype specific luciferase immunoprecipitation system (LIPS) assays and a novel Spike-RBD bridging LIPS total-antibody assay. We utilized pre-pandemic (n=984) and confirmed/suspected recent COVID-19 sera taken pre-vaccination rollout in 2020 (n=269).

Breastmilk is a human right.

All babies have a human right to breastmilk, based on the right to life, to adequate nutrition and to the highest attainable standard of health, and based on women's rights, which include the right to breastfeed, to breastfeeding education and to paid maternity leave. This article examines international human rights law as it applies to breastfeeding, with particular reference to the Australian context. It also lays out the rights obligations of organisations such as the Australian Breastfeeding Association, their relations with government and the merits of such organisations adopting a rights-based approach to advocacy.
