NNii is dedicated to providing the latest scientific information on immunizations to the public, healthcare providers, policy makers, and the media. Neither NNii nor its sponsoring corporation, I4PH, accept any financial support from the pharmaceutical industry or the federal government.
NNii receives contributions from some of its affiliate organizations, plus gifts from the public. Nonetheless, NNii maintains strict editorial independence in all publications and print materials
Other income comes from the sale of publications authored by NNii staff. Proceeds from all publications go directly to Immunizations for Public Health for the benefit of NNii; the authors receive no income from their publications.
