In just a few months, Brazil will host the 2016 Olympics, the most competitive global athletic event of the year. But another important race for the people of that country–and millions more around the world–has already begun. BIO members and others across the public health community are aiming to break vaccine development records to find solutions for unpredictable diseases like Zika and dengue. Both produce a devastating impact on tropical and subtropical countries like Brazil, and this impact could worsen. Only one thing can bring them under control quickly: cross-border, cross-functional collaboration. As an industry, we need to actively participate evermore openly in scientific, regulatory, and operational connections amongst all of the players in the vaccine ecosystem to help address these urgent public health needs.
