Lab rodent species commonly used to study the visual system and its development (hamsters, rats, and mice) are crepuscular/nocturnal, altricial, and possess simpler visual systems than carnivores and primates. To widen the spectra of studied species, here we introduce an alternative model, the Chilean degu (). This diurnal, precocial Caviomorph rodent has a cone enriched, well-structured retina, and well-developed central visual projections.

- Oral cholera vaccination (OCV) campaigns are being evaluated for their cost-effectiveness in refugee camps, particularly in the Maela camp in Thailand, where cholera outbreaks occur with a notable incidence rate.
- The analysis showed that the economic costs of the OCV campaign were significant, totaling around USD 289,561, with a high incremental cost per death averted, but it indicated that higher cholera incidence or case fatality rates could improve cost-effectiveness.
- Sensitivity analyses demonstrated that adjusting the case fatality rate or incidence could lead to more favorable cost-per-DALY (disability-adjusted life years) figures, suggesting strategic use of OCV campaigns in outbreak-prone areas.
Article Synopsis
- The CDC partnered with African Field Epidemiology Network and Sydani Group in 2022 to aid COVID-19 vaccination efforts in Nigeria and assess the financial costs associated with these vaccination campaigns.
- The study used existing financial data to evaluate costs per dose for vaccination activities in nine states, excluding certain expenses like vaccine purchases and transport.
- The total expenditure for administering 7.46 million doses was approximately US$6.29 million, with the main costs attributed to fieldwork activities (86%) and labor (58%), particularly for vaccination teams and incentives.
Background: Historically, lack of data on cost-effectiveness of influenza vaccination has been identified as a barrier to vaccine use in low- and middle-income countries. We conducted a systematic review of economic evaluations describing (1) costs of influenza illness; (2) costs of influenza vaccination programs; and (3) vaccination cost-effectiveness from low- and middle-income countries to assess if gaps persist that could hinder global implementation of influenza vaccination programs.
Methods And Findings: We performed a systematic search in Medline, Embase, Cochrane Library, CINAHL, and Scopus in January 2022 and October 2023 using a combination of the following key words: "influenza" AND "cost" OR "economic.
Globally, there were an estimated 9.8 million measles cases and 207 500 measles deaths in 2019. As the effort to eliminate measles around the world continues, modeling remains a valuable tool for public health decision-makers and program implementers.
