As the United Nations General Assembly kicks off general debate on the post-2015 development agenda this week, advocates of a universal health coverage (UHC) target are rallying other organizations to build and showcase support around UHC. These efforts include high-profile events on Monday and Tuesday, both hosted by the Rockefeller Foundation with partner support. On Wednesday, Johnson & Johnson hosted an event on the key role of frontline health workers to efforts like these. This post, which originally appeared on The Lancet Global Health Blog, is part of a "Rallying for UHC" series: MSH bloggers expanding on the themes raised by these events and considering the road ahead for UHC in post-2015 discussions. Readers can participate by adding comments on the blog posts, or joining the conversation on Twitter with the hashtag.
