There is information missing from the Competing Interests statement. While the authors have already declared in the Funding statement that GlaxoSmithKline (GSK) Biologicals SA was the funding source and was involved in all stages of the study conduct and analysis, they did not disclose all potential financial competing interests for each individual co-author related to GSK funding in the original competing interests statement due to a misunderstanding in what was expected from them.
