Psst, the fact that you can't imagine it may be a flaming clue. You should consider the possibility that you've become a brainwashed ideologue. I say this, because:

"The National Institutes of Health (NIH) is the primary agency of the United States government responsible for biomedical and public health research, founded in the late 1870s... As of 2013, the IRP had 1,200 principal investigators and more than 4,000 postdoctoral fellows in basic, translational, and clinical research, being the largest biomedical research institution in the world... 

The NIH comprises 27 separate institutes and centers of different biomedical disciplines and is responsible for many scientific accomplishments, including... the creation of vaccines against hepatitis, Haemophilus influenzae (HIB), and human papillomavirus (HPV)."
