The search for a global Strep A vaccine has narrowed after researchers sequenced the DNA of more than 2,000 Group A Streptococcus samples from around the world. Researchers from the Wellcome Sanger Institute and collaborators revealed the differences between strains from more than 20 countries, and identified potential vaccine targets present in strains from all countries sampled. The study in Nature Genetics points to the possibility of developing an effective global vaccine against Strep A.
