Vaccine Impact

Background: Cervical cancer is the second most common cancer among women in Ethiopia, India, Nigeria, and Pakistan. However, of these four countries, only Ethiopia has introduced human papillomavirus (HPV) vaccination at the national level in 2018 and India in a few states in 2016. Our study objective was to estimate the potential health impact of HPV vaccination among ten cohorts of 9-year-old girls from 2021-2030 in Ethiopia, India, Nigeria, and Pakistan using two independent mathematical models, and assess similarities and differences in vaccine impact projections through comparative modelling analysis. Methods: Using two widely published models (Harvard and PRIME) to estimate HPV vaccination impact, we simulated a vaccination scenario of 90% annual coverage among 9-year-old girls from 2021-2030 in Ethiopia, India, Nigeria, and Pakistan. We estimated the potential health impact in terms of cervical cancer cases, deaths, and disability-adjusted life years (DALYs) averted among vaccinated cohorts from the time of vaccination until 2100. We also conducted a comparative modelling analysis to understand the differences in vaccine impact estimates generated by the two models. Results: Prior to harmonising model assumptions, the range between the PRIME model and the Harvard model for the potential health impact of HPV vaccination in terms of the number of cervical cancer cases averted among girls vaccinated 2021-2030 between the year of vaccination and 2100 was: 262,000 to 270,000 in Ethiopia; 1,640,000 to 1,970,000 in India; 330,000 to 336,000 in Nigeria; and 111,000 to 133,000 in Pakistan. When harmonising model assumptions, alignment on HPV type distribution significantly narrowed the differences in vaccine impact estimates. Conclusions: The main difference in estimates for cases, deaths, and DALYs averted by vaccination between the models are due to variation in interpretation around data on cervical cancer attribution to HPV-16/18; differences in estimates for DALYs averted are additionally due to differences in age-specific remaining life expectancy over time between the two models. As countries make progress towards the World Health Organization targets for cervical cancer elimination, continued explorations of underlying differences in model inputs, assumptions, and results when examining cervical cancer prevention policy will be critical.

Abstract Purpose This study aims to provide insights into the development of firm strategies of international expansion by examining the direct relationship between internationalization speed and firm performance and by exploring the interactive role played by networking capability. Design/methodology/approach This is an empirical study based on survey data collected from 343 small and medium-sized enterprises operating in Australia and New Zealand. Regression modelling analysis was performed. Findings This study found an inverted U-shape relationship between the speed at which a firm expands internationally and its performance. Expanding too fast or too slow leads to lower performance, and this performance implication is because of an interactive effect of the firm's networking capability. Research limitations/implications This study contributes to the literature by generating insights into how firm strategies of international expansion lead to improvement of firm performance, thereby giving guidance and providing suggestions to managers regarding how quickly to internationalize. Practical implications This study contributes to the literature by generating insights into how firm strategies of international expansion lead to improvement of firm performance and by providing suggestions to managers regarding decision-making in developing strategies for international expansion speed. Originality/value This is an original study based on empirical data collected from a management survey.
