Competing Interests
The authors have read the journal's policy and have the following conflicts. AvdE has received grants from Pfizer for research on pneumococcal infections and from Novartis for research on antigen variability in meningococci and has received consulting fees from Pfizer and GSK. DB has received consulting fees from Pfizer. EAMS declares to have received unrestricted research support from Pfizer, grant support for (vaccine) studies from Pfizer and GSK and fees paid to the institution for advisory boards and participation in independent data monitoring committees for Pfizer and GSK. KT has received consulting fees from Pfizer and grant support for studies on pneumococcal carriage from Pfizer. This does not alter the authors' adherence to PLOS ONE policies on sharing data and materials. All other authors report no potential conflicts.
