Influenza epidemiology and immunization during pregnancy: Final report of a World Health Organization working group

From 2014 to 2017, the World Health Organization convened a working group to evaluate influenza disease burden and vaccine efficacy to inform estimates of maternal influenza immunization program impact. The group evaluated existing systematic reviews and relevant primary studies, and conducted four new systematic reviews. There was strong evidence that maternal influenza immunization prevented influenza illness in pregnant women and their infants, although data on severe illness prevention were lacking. The limited number of studies reporting influenza incidence in pregnant women and infants under six months had highly variable estimates and underrepresented low- and middle-income countries. The evidence that maternal influenza immunization reduces the risk of adverse birth outcomes was conflicting, and many observational studies were subject to substantial bias. The lack of scientific clarity regarding disease burden or magnitude of vaccine efficacy against severe illness poses challenges for robust estimation of the potential impact of maternal influenza immunization programs

Inverting the Large Lecture Class: Active Learning in an Introductory International Relations Course

The inverted classroom model (ICM) is an active learning approach that reserves class meetings for hands-on exercises while shifting content learning to the preparatory stage. The ICM offers possibilities for pursuing higher-order learning objectives even in large classes. However, there are contradicting reports about students’ reactions to this kind of teaching innovation. With the ICM making inroads in political science teaching, this paper discusses how students evaluate this method.We report results from an application of the ICM to an introductory international relations course. In our course, students’ reactions to the ICM varied greatly. Using a regression analysis of student evaluation scores, we find that students’ preference for collaborative learning best predicted their preference for the ICM over the traditional lecture format
