Competing Interests

I have read the journal’s policy and have the following conflicts: CG, NB, TO, JL are employees of GlaxoSmithKline Vaccines. CG and JL declare stock ownership in the GlaxoSmithKline group of companies. CG and JL are also inventor on patents owned by GlaxoSmithKline group of companies (WO/2013/096430). This does not alter our adherence to PLOS ONE policies on sharing data and materials.
