Later history
In the 1960s, virologist and cancer researcher
Chester M. Southam injected

cancer cells into patients at the Jewish Chronic Disease Hospital.
When three doctors resigned after refusing to inject patients without their consent, the experiment gained considerable media attention.
The NIH was a major source of funding for Southam's research and had required all research involving human subjects to obtain their consent prior to any experimentation.
Upon investigating all of their grantee institutions, the NIH discovered that the majority of them did not protect the rights of human subjects. From then on, the NIH has required all grantee institutions to approve any research proposals involving human experimentation with review boards.
In 1967, the Division of Regional Medical Programs was created to administer grants for research for heart disease, cancer, and strokes. That same year, the NIH director lobbied the White House for increased federal funding in order to increase research and the speed with which health benefits could be brought to the people. An advisory committee was formed to oversee the further development of the NIH and its research programs. By 1971 cancer research was in full force and President Nixon signed the
National Cancer Act, initiating a National Cancer Program, President's Cancer Panel, National Cancer Advisory Board, and 15 new research, training, and demonstration centers.
Funding for the NIH has often been a source of contention in Congress, serving as a proxy for the political currents of the time. In 1992, the NIH encompassed nearly 1 percent of the federal government's operating budget and controlled more than 50 percent of all funding for health research, and 85 percent of all funding for health studies in universities.
While government funding for research in other disciplines has been increasing at a rate similar to inflation since the 1970s, research funding for the NIH nearly tripled through the 1990s and early 2000s, but has remained relatively stagnant since then.
By the 1990s, the NIH committee focus had shifted to DNA research and launched the
Human Genome Project
The Human Genome Project (HGP) was an international scientific research project with the goal of determining the base pairs that make up human DNA, and of identifying and mapping all of the genes of the human genome from both a physical and a f ...

NIH Interagency Pain Research Coordinating Committee
On February 13, 2012, the National Institutes of Health (NIH) announced a new group of individuals assigned to research pain. This committee is composed of researchers from different organizations and will focus to "coordinate pain research activities across the federal government with the goals of stimulating pain research collaboration… and providing an important avenue for public involvement" ("Members of new", 2012). With a committee such as this research will not be conducted by each individual organization or person but instead a collaborating group which will increase the information available. With this hopefully more pain management will be available including techniques for arthritis sufferers. In 2020
Beth Darnall, American scientist and pain psychologist, was appointed as scientific member of the group.
Economic return
In 2000, the Joint Economic Committee of Congress reported NIH research, which was funded at $16 billion a year in 2000, that some econometric studies had given a rate of return of 25 to 40 percent per year by reducing the economic cost of illness in the US. It found that of the 21 drugs with the highest therapeutic impact on society introduced between 1965 and 1992, public funding was "instrumental" for 15. As of 2011 NIH-supported research helped to discover 153 new FDA-approved drugs, vaccines, and new indications for drugs in the 40 years prior. One study found NIH funding aided either directly or indirectly in developing the drugs or drug targets for all of the 210 FDA-approved drugs from 2010 to 2016. In 2015, Pierre Azoulay et al. estimated $10 million invested in research generated two to three new patents.

EcoHealth Alliance has been the subject of controversy and increased scrutiny due to its ties to the
Wuhan Institute of Virology (WIV)—which has been at the center of speculation since early 2020 that SARS-CoV-2 may have escaped in a lab incident. Under political pressure, the NIH withdrew funding to EcoHealth Alliance in July 2020.
Funding
Budget and politics
To allocate funds, the NIH must first obtain its budget from Congress. This process begins with institute and center (IC) leaders collaborating with scientists to determine the most important and promising research areas within their fields. IC leaders discuss research areas with NIH management who then develops a budget request for continuing projects, new research proposals, and new initiatives from the Director. NIH submits its budget request to the
Department of Health and Human Services
The United States Department of Health and Human Services (HHS), is a cabinet-level executive branch

(HHS), and the HHS considers this request as a portion of its budget. Many adjustments and appeals occur between NIH and HHS before the agency submits NIH's budget request to the
Office of Management and Budget
The Office of Management and Budget (OMB) is the largest office within the Executive Office of the President of the United States (EOP). OMB's most prominent function is to produce the president's budget, but it also examines agency programs, poli ...
(OMB). OMB determines what amounts and research areas are approved for incorporation into the President's final budget. The President then sends NIH's budget request to Congress in February for the next fiscal year's allocations. The House and Senate Appropriations Subcommittees deliberate and by fall, Congress usually appropriates funding. This process takes approximately 18 months before the NIH can allocate any actual funds.

Historical funding
Over the last century, the responsibility to allocate funding has shifted from the OD and Advisory Committee to the individual ICs and Congress increasingly set apart funding for particular causes. In the 1970s, Congress began to earmark funds specifically for cancer research, and in the 1980s there was a significant amount allocated for AIDS/HIV research.
Funding for the NIH has often been a source of contention in Congress, serving as a proxy for the political currents of the time. During the 1980s, President Reagan repeatedly tried to cut funding for research, only to see Congress partly restore funding. The political contention over NIH funding slowed the nation's response to the AIDS epidemic; while AIDS was reported in newspaper articles from 1981, no funding was provided for research on the disease. In 1984 National Cancer Institute scientists found implications that "variants of a human cancer virus called HTLV-III are the primary cause of acquired immunodeficiency syndrome (AIDS)," a new epidemic that gripped the nation.
In 1992, the NIH encompassed nearly 1 percent of the federal government's operating budget and controlled more than 50 percent of all funding for health research and 85 percent of all funding for health studies in universities.
From 1993 to 2001 the NIH budget doubled. For a time, funding essentially remained flat, and for seven years following the financial crisis, the NIH budget struggled to keep up with inflation.
In 1999 Congress increased the NIH's budget by $2.3 billion
to $17.2 billion in 2000.
In 2009 Congress again increased the NIH budget to $31 billion in 2010.
In 2017 and 2018, Congress passed laws with bipartisan support that substantially increasing appropriations for NIH, which was 37.3 billion dollars annually in FY2018.
Extramural research
Researchers at universities or other institutions outside of NIH can apply for
research project grants (RPGs) from the NIH. There are numerous funding mechanisms for different project types (e.g., basic research, clinical research, etc.) and career stages (e.g., early career, postdoc fellowships, etc.). The NIH regularly issues "requests for applications" (RFAs), e.g., on specific programmatic priorities or timely medical problems (such as

research in early 2016). In addition, researchers can apply for "investigator-initiated grants" whose subject is determined by the scientist.
The total number of applicants has increased substantially, from about 60,000 investigators who had applied during the period from 1999 to 2003 to slightly less than 90,000 in who had applied during the period from 2011 to 2015.
Due to this, the "cumulative investigator rate", that is, the likelihood that unique investigators are funded over a 5-year window, has declined from 43% to 31%.
R01 grants are the most common funding mechanism and include investigator-initiated projects. The roughly 27,000 to 29,000 R01 applications had a funding success of 17-19% during 2012 though 2014. Similarly, the 13,000 to 14,000 R21 applications had a funding success of 13-14% during the same period. In FY 2016, the total number of grant applications received by the NIH was 54,220, with approximately 19% being awarded funding.
Institutes have varying funding rates. The National Cancer Institute awarded funding to 12% of applicants, while the National Institute for General Medical Science awarded funding to 30% of applicants.

Funding criteria
NIH employs five broad decision criteria in its funding policy. First, ensure the highest quality of scientific research by employing an arduous peer review process. Second, seize opportunities that have the greatest potential to yield new knowledge and that will lead to better prevention and treatment of disease. Third, maintain a diverse research portfolio in order to capitalize on major discoveries in a variety of fields such as cell biology, genetics, physics, engineering, and computer science. Fourth, address public health needs according to the disease burden (e.g., prevalence and mortality). And fifth, construct and support the scientific infrastructure (e.g., well-equipped laboratories and safe research facilities) necessary to conduct research.
Advisory committee members advise the institute on policy and procedures affecting the external research programs and provide a second level of review for all grant and cooperative agreement applications considered by the Institute for funding.
Gender and sex bias
In 2014, it was announced that the NIH is directing scientists to perform their experiments with both female and male animals, or cells derived from females as well as males if they are studying cell cultures, and that the NIH would take the balance of each study design into consideration when awarding grants. The announcement also stated that this rule would probably not apply when studying sex-specific diseases (for example, ovarian or testicular cancer).
Stakeholders
General public
One of the goals of the NIH is to "expand the base in medical and associated sciences in order to ensure a continued high return on the public investment in research." Taxpayer dollars funding NIH are from the taxpayers, making them the primary beneficiaries of advances in research. Thus, the general public is a key stakeholder in the decisions resulting from the NIH funding policy. However, some in the general public do not feel their interests are being represented, and individuals have formed patient advocacy groups to represent their own interests.
Extramural researchers and scientists
Important stakeholders of the NIH funding policy include researchers and scientists. Extramural researchers differ from intramural researchers in that they are not employed by the NIH but may apply for funding. Throughout the history of the NIH, the amount of funding received has increased, but the proportion to each IC remains relatively constant. The individual ICs then decide who will receive the grant money and how much will be allotted.
Policy changes on who receives funding significantly affect researchers. For example, the NIH has recently attempted to approve more first-time NIH R01 applicants or the research grant applications of young scientists. To encourage the participation of young scientists, the application process has been shortened and made easier. In addition, first-time applicants are being offered more funding for their research grants than those who have received grants in the past.
Commercial partnerships
In 2011 and 2012, the Department of Health and Human Services Office of Inspector General published a series of audit reports revealing that throughout the fiscal years 2000–2010, institutes under the aegis of the NIH did not comply with the time and amount requirements specified in appropriations statutes, in awarding federal contracts to commercial partners, committing the federal government to tens of millions of dollars of expenditure ahead of appropriation of funds from Congress.
