Should a highly pathogenic avian influenza virus, such as the H5N1 virus type currently circulating in birds, become transmissible among humans, an effective vaccine, rapidly available in vast quantities, would be the best tool to prevent high case-fatalities and the breakdown of health and social services. The number of vaccine doses that could be produced on demand has risen sharply over the last few years; however, it is still alarmingly short of the 13 billion doses that would be needed if two doses were required to protect fully the world's population. Most developing countries would be last in the queue to benefit from a pandemic vaccine. The World Health Organization, together with governments, the pharmaceutical industry and other stakeholders, has been implementing the global pandemic influenza action plan to increase vaccine supply since 2006. Building capacity in developing countries to manufacture influenza vaccine is an integral part of this plan, as well as research and development into more efficacious technologies, e.g. those that allow significant dose-sparing. To this end, the influenza vaccine technology transfer initiative was launched in 2007 and, to date, vaccine manufacturers in 11 developing countries have received grants to acquire the capacity to produce inactivated or live attenuated influenza vaccine for their populations. In addition, a centralized 'hub' has been established to facilitate training in the new technologies for scientists and regulators in the countries. This supplement of Vaccine is devoted to showcasing the interim results of the WHO initiative and the impressive progress made by the developing country manufacturers.
Objectives: To assess the epidemiological features of 76 KPC producing K. pneumoniae isolates (KPC-Kp) recovered in 3 hospitals of Buenos Aires, Argentina, during 2015-2017. Methods: Antimicrobial susceptibilities were determined according to CLSI. Molecular typing of KPC-Kp was performed by PFGE-XbaI and MLST. Plasmid encoded genes involved in carbapenem, fosfomycin and colistin resistance were detected by PCR and sequencing. Also mgrB inactivation was investigated in those colistin resistance isolates. Genetic platforms involved in horizontal spread of bla KPC were investigated by PCR mapping.Results: Besides β-lactams, high resistance rates were observed for gentamycin, quinolones and trimethoprim-sulfamethoxazole. KPC-Kp ST258 corresponded to

Background: Regulatory preparedness for public health emergencies is critical. However, responses to past emergencies, such as the 2009 H1N1 influenza pandemic and medical product shortages, have revealed sizable gaps in countries' regulatory capacity and preparedness. A systematic analysis of the regulatory preparedness of countries around the world has not yet been performed. The purpose of this study was to analyze and document the current regulatory preparedness status, highlight the related gaps and challenges in order to propose strategic, harmonized, and sustainable regulatory solutions to improve future responses to public health emergencies.Methods: From 2016 to 2020, we used the World Health Organization (WHO)'s Global Benchmarking Tool (GBT), a standardized instrument for identifying national regulatory authorities' strengths and gaps, to analyze the regulatory preparedness of 84 Member States, 95% of which were low- or middle-income countries. We analyzed whether participating Member States had not implemented, displayed ongoing implementation, had partially implemented, or had fully implemented 10 of the GBT's 268 sub-indicators most relevant to regulatory preparedness for public health emergencies.Findings: Only 10 Member States (12%) that underwent benchmarking had fully implemented all 10 sub-indicators related to regulatory preparedness for public health emergencies; 34 (40%) had fully implemented ≥50% of the emergency sub-indicators, and 20 (24%) had not fully implemented any of the sub-indicators. With regard to individual sub-indicators, regulatory preparedness ranged from 19 Member States (23%) fully implementing reliance on clinical trial decisions of others to 45 (59%) fully implementing legal provisions to fast-track (or expedite) marketing authorization applications.Interpretation: Many WHO Member States have limited regulatory preparedness for a public health emergency. Strengthening regulatory systems and promoting Good Regulatory Practices and reliance in these countries, to enable efficient response to emergencies, should be a global health priority.
