First-dose ChAdOx1 and BNT162b2 COVID-19 vaccines and thrombocytopenic, thromboembolic and hemorrhagic events in Scotland
Reports of ChAdOx1 vaccineâassociated thrombocytopenia and vascular adverse events have led to some countries restricting its use. Using a national prospective cohort, we estimated associations between exposure to first-dose ChAdOx1 or BNT162b2 vaccination and hematological and vascular adverse events using a nested incident-matched case-control study and a confirmatory self-controlled case series (SCCS) analysis. An association was found between ChAdOx1 vaccination and idiopathic thrombocytopenic purpura (ITP) (0â27 d after vaccination; adjusted rate ratio (aRR) = 5.77, 95% confidence interval (CI), 2.41â13.83), with an estimated incidence of 1.13 (0.62â1.63) cases per 100,000 doses. An SCCS analysis confirmed that this was unlikely due to bias (RRâ=â1.98 (1.29â3.02)). There was also an increased risk for arterial thromboembolic events (aRR = 1.22, 1.12â1.34) 0â27 d after vaccination, with an SCCS RR of 0.97 (0.93â1.02). For hemorrhagic events 0â27 d after vaccination, the aRR was 1.48 (1.12â1.96), with an SCCS RR of 0.95 (0.82â1.11). A first dose of ChAdOx1 was found to be associated with small increased risks of ITP, with suggestive evidence of an increased risk of arterial thromboembolic and hemorrhagic events. The attenuation of effect found in the SCCS analysis means that there is the potential for overestimation of the reported results, which might indicate the presence of some residual confounding or confounding by indication. Public health authorities should inform their jurisdictions of these relatively small increased risks associated with ChAdOx1. No positive associations were seen between BNT162b2 and thrombocytopenic, thromboembolic and hemorrhagic events
Australia: Public Health Genomics
Australia has a multicultural society that has arisen from continuing migration. While the population is relatively small, just over 20.7 million, it is genetically diverse and is spread over a large land mass. The federal system of government is democratic, based on states and territories, and there is a socialized healthcare system, in which public and private models operate in parallel. Clinical genetics services are publicly funded by State Departments of Health, rather than by the Commonwealth Government, with the model of service provision varying from state to state. Each of these factors has important implications for the effective delivery of genetic screening programs and clinical genetic services that meet the needs of all Australians. Population genetic screening occurs throughout Australia predominantly as newborn screening programs and to identify pregnancies at risk of chromosomal and neural tube defects, while carrier screening programs are essentially ad hoc. Despite inevitable tensions between federal and state policies, there is increasing evidence of the development of national policy in a range of genetic issues, not least in newborn screening, genetic testing, and health professional education. However, further work is necessary to establish frameworks for the regulation and funding of new genetic tests across state/federal boundaries, which will be crucial to the establishment of a national approach to public health genomics policy

Host Plant Records for Fruit Flies (Diptera: Tephritidae: Dacini) in the Pacific Islands: 2. Infestation Statistics on Economic Hosts
Detailed host records are listed for 39 species of Bactrocera and 2 species of Dacus fruit flies, infesting 98 species of commercial and edible fruits in the Pacific Island Countries and Territories, based on sampling and incubating in laboratory almost 13,000 field collected samples, or over 380,000 fruits. For each host-fly-country association, quantitative data are presented on the weight and number of fruits collected, the proportion of infested samples, the number of adult flies emerged per kg of fruits and, whenever available, the percentage of individual fruits infested. All the published records of each fly-host-country association are cited and erroneous or dubious published records are rectified or commented. Laboratory forced infestation data are also cited and reviewed
