United States Military HIV Research Program
The United States Military HIV Research Program (USMHRP or MHRP) was initiated by the United States Congress in 1986, in reaction to the threat of lost effectiveness of U.S./Allied troops due to HIV infection. The mission of MHRP is to develop an HIV-1 vaccine, provide prevention, care, and treatment, and conduct meaningful HIV/AIDS research for the global community through the President's Emergency Plan for AIDS Relief (PEPFAR). It is centered at the Walter Reed Army Institute of Research (WRAIR), and has established five international research sites in Africa and Asia (Tanzania, Kenya, Nigeria, Uganda, and Thailand). MHRP also partners with the Armed Forces Research Institute of Medical Sciences (AFRIMS) in Thailand. MHRP works closely with The Henry M. Jackson Foundation for the Advancement of Military Medicine (HJF), most notably in the development of the RV144 HIV vaccine in Thailand. MHRP is the largest research program supported by the HJF.{{Cite web|url=https://www.hjf.org/site/assets/files/1028/hjf_annualreport_2016.pdf|title=HJF Annual Report 2016 |date=2016|website=HJF |access-date= 26 October 2018 }}
Funding
The MHRP is a $175 million program which receives funding for research and treatment endeavors from the Department of Defense ($28 million), PEPFAR, and other organizations such as the Bill and Melinda Gates Foundation and the National Institute of Allergy and Infectious Diseases.{{Cite web|url=https://www.niaid.nih.gov/research/military-hiv-research-program|title=U.S. Military HIV Research Program (MHRP) | work = NIH: National Institute of Allergy and Infectious Diseases |access-date=2018-10-26}}{{Cite news|url=https://sciencespeaksblog.org/2011/12/13/budget-cuts-threaten-military-hiv-research-program/|title=Budget cuts threaten Military HIV Research Program|date=2011-12-13|work=Science Speaks: Global ID News|access-date=2018-10-26|language=en-US}} Some of MHRP's collaborative vaccine-as-treatment research is funded by Janssen, a division of Johnson & Johnson. MHRP studies in combination approaches to HIV are made possible by a competitive grant that they competed for from a NIH-funded Martin Delaney Collaboratorive.{{Cite web|url=https://www.hjf.org/site/assets/files/1028/hjf_annualreport_2016.pdf|title=HJF Annual Report 2016 |date=2016|website=HJF | access-date= 26 October 2018 }}
In 2012, a MHRP scientist named Dr. Gary R. Matyas proposed a vaccine to treat heroin addiction and prevent those who received this vaccine from contracting HIV. Matyas was awarded the NIDA Avant-Garde Award for Medications Development for this proposition, which gave him $1 million per year for five years to continue his research at MHRP on the dual vaccine.{{Cite news|url=https://archives.drugabuse.gov/news-events/news-releases/2012/07/nida-supports-development-combined-anti-heroin-hiv-vaccine|title=NIDA supports development of combined anti-heroin and HIV vaccine|date=2012-07-25|access-date=2018-11-07|language=en-US}}
International vaccine research
The program's most notable contribution to HIV/AIDS medical research was the RV 144 vaccine study of over 16,000 volunteers in Thailand. In September 2009, the MHRP and the Thai Ministry of Health conducted the first successful HIV/AIDS vaccine trial to show effective prevention in humans, with a final prevention rate of 31%.{{cite journal | vauthors = Karasavvas N, Billings E, Rao M, Williams C, Zolla-Pazner S, Bailer RT, Koup RA, Madnote S, Arworn D, Shen X, Tomaras GD, Currier JR, Jiang M, Magaret C, Andrews C, Gottardo R, Gilbert P, Cardozo TJ, Rerks-Ngarm S, Nitayaphan S, Pitisuttithum P, Kaewkungwal J, Paris R, Greene K, Gao H, Gurunathan S, Tartaglia J, Sinangil F, Korber BT, Montefiori DC, Mascola JR, Robb ML, Haynes BF, Ngauy V, Michael NL, Kim JH, de Souza MS | display-authors = 6 | title = The Thai Phase III HIV Type 1 Vaccine trial (RV144) regimen induces antibodies that target conserved regions within the V2 loop of gp120 | journal = AIDS Research and Human Retroviruses | volume = 28 | issue = 11 | pages = 1444–57 | date = November 2012 | pmid = 23035746 | pmc = 3484815 | doi = 10.1089/aid.2012.0103 }}{{Cite news|url=http://www.aidsmap.com/The-RV144-trial/page/2028003/|title=Efficacy trials - The RV144 trial|access-date=2018-10-26}}{{cite news | url= https://www.nytimes.com/2009/09/25/health/research/25aids.html | title=For First Time, AIDS Vaccine Shows Some Success | work= New York Times | access-date=2009-09-24 | first=Donald G. | last=McNeil | name-list-style = vanc | date=2009-09-25}}{{cite web|url=http://www.medicalnewstoday.com/articles/165277.php|title=In Thailand Clinical Study, HIV Vaccine Regimen Demonstrates Modest Preventive Effect|date=2009-09-25|author=Medical News Today}}{{cite web|url=http://www.the-scientist.com/blog/display/55995/|title=HIV vax testers react to Thai trial|author=Bob Grant|date=2009-09-24}}{{cite web |url=http://www.hivresearch.org/phase3/phase3pressrelease.html |title=HIV Vaccine Study First to Show Some Effectiveness in Preventing HIV |publisher=US Military HIV Research Program |access-date=2009-09-24 |url-status=dead |archive-url=https://web.archive.org/web/20090927095357/http://www.hivresearch.org/phase3/phase3pressrelease.html |archive-date=September 27, 2009 }} Also see [http://www.hivresearch.org/phase3/RV144-FAQs-20090924.pdf Frequently asked questions regarding the RV144 Phase III HIV Vaccine Trial] and [http://www.hivresearch.org/global-efforts/thailand.html Thailand MHRP site information] {{Webarchive|url=https://web.archive.org/web/20080907223113/http://hivresearch.org/global-efforts/thailand.html |date=2008-09-07 }}.{{cite web | url=http://www.sanofipasteur.com/sanofi-pasteur2/sp-media/SP_CORP/EN/54/942/HIV%20RESULTS%20240909%20ENG.pdf | title=Sanofi Pasteur Commends Results of First HIV Vaccine Study to Show Some Effectiveness in Preventing HIV | publisher=Sanofi Pasteur | access-date=2009-09-24 | archive-url=https://web.archive.org/web/20110716005001/http://www.sanofipasteur.com/sanofi-pasteur2/sp-media/SP_CORP/EN/54/942/HIV%20RESULTS%20240909%20ENG.pdf | archive-date=2011-07-16 | url-status=dead }}{{cite web | url=http://www.gsid.org/downloads/GSIDRV144_Press_Release.pdf | title=Prime-Boost Vaccine Study Shows Modest Effect in Preventing HIV | publisher= Global Solutions for Infectious Diseases | access-date=2009-09-24}} Although the efficacy is modest, this trial is significant because it proved that it is possible to develop an HIV vaccine.{{cn|date=September 2022}}
The breakthrough led to increased interest in research on RV144 and the foundation of partnerships such as the Pox-Protein Public-Private Partnership (P5), a mosaic of public and private entities that focus on building on the success of RV144.{{Cite web|url=http://www.vaccineenterprise.org/content/P5Partnership|title=P5 Partnership|website=Global HIV Vaccine Enterprise|language=en|access-date=2018-10-26}} MHRP also provides study leadership, and is working with researchers around the globe to dissect the results from the RV144 trial and to design future clinical trials to translate a scientific milestone into an eventual public health tool. RV144 remains the only instance of successful preventative HIV vaccination.{{cite journal | vauthors = Hontelez JA, Nagelkerke N, Bärnighausen T, Bakker R, Tanser F, Newell ML, Lurie MN, Baltussen R, de Vlas SJ | display-authors = 6 | title = The potential impact of RV144-like vaccines in rural South Africa: a study using the STDSIM microsimulation model | journal = Vaccine | volume = 29 | issue = 36 | pages = 6100–6 | date = August 2011 | pmid = 21703321 | pmc = 3157643 | doi = 10.1016/j.vaccine.2011.06.059 }}
MHRP scientists are also pursuing other strategies to target multiple sub-types of HIV, including modified vaccinia virus Ankara (MVA) vaccines, which were initially developed by collaborating scientists from WRAIR, NIAID, the National Institutes of Health, and the Laboratory of Viral Diseases (LVD). MHRP has ongoing studies and clinical trials using different types of MVA vaccines in Uganda and Thailand, with progress milestones including partial protection and viral load reduction in monkeys being infected with Simian Immunodeficiency Virus (SIV).{{Cite web|url=https://www.hjf.org/site/assets/files/1028/hjf_annualreport_2016.pdf|title=HJF Annual Report 2016 | date=2016|website=HJF | access-date= 26 October 2018 }}{{Cite web|url=https://www.hivresearch.org/mva-vaccine|title=MVA Vaccine|website=MHRP {{!}} Military HIV Research Program|language=en|access-date=2018-10-26}}
Prevention, care, and treatment
In addition to vaccine research, the MHRP provides prevention, care, and treatment services to the communities where they conduct research.{{cite journal | vauthors = Reilly L | title = U.S. Military HIV Research Program: successfully integrating HIV vaccine research with prevention, care, and treatment | journal = Military Medicine | volume = 175 | issue = 7 Suppl | pages = 42–4 | date = July 2010 | pmid = 23634478 | doi = 10.7205/MILMED-D-10-00168 | doi-access = free }} According to the Henry M. Jackson Foundation for the Advancement of Military Medicine's 2016 annual report, MHRP works with local programs around the world to support more than 240,000 patients on antiretroviral therapy and to make HIV testing/advising accessible to more than 1.1 million people.{{Cite web|url=https://www.hjf.org/site/assets/files/1028/hjf_annualreport_2016.pdf|title=HJF Annual Report 2016 | date=2016|website=HJF | access-date= 26 October 2018 }} Using existing in-country technical expertise and administrative infrastructure, MHRP expands partnerships with local researchers, health care services and NGOs in Africa to implement PEPFAR activities. Goals include providing counseling, testing, prevention of mother to child transmission, full access to antiretroviral therapy, home-based care, and care for orphans and vulnerable children. MHRP also conducts therapeutic research, tracks the HIV epidemic in active-duty forces, assesses the risk of HIV exposure to deployed U.S. and allied forces overseas, and conducts all HIV-1 testing for the Army.{{cn|date=September 2022}}
In 2008, MHRP helped evaluate the efficacy of new Rapid Diagnostic Tests (RDT) for HIV types 1 and 2.{{cite journal | vauthors = Manak MM, Njoku OS, Shutt A, Malia J, Jagodzinski LL, Milazzo M, Suleiman A, Ogundeji AA, Nelson R, Ayemoba OR, O'Connell RJ, Singer DE, Michael NL, Peel SA | display-authors = 6 | title = Evaluation of Performance of Two Rapid Tests for Detection of HIV-1 and -2 in High- and Low-Prevalence Populations in Nigeria | journal = Journal of Clinical Microbiology | volume = 53 | issue = 11 | pages = 3501–6 | date = November 2015 | pmid = 26311857 | pmc = 4609716 | doi = 10.1128/JCM.01432-15 }} They were developed to be able to quickly test the blood of soldiers who transfuse blood to wounded soldiers in battle situations. This technology prevents transmission of HIV, HCV, and HBV from soldier to soldier and helps keep these diseases from weakening the fighting force further. Additionally, MHRP conducted the first study to characterize that current clinical testing methods can have difficulty detecting HIV viral presence in persons with acute infections.{{cite journal | vauthors = Robb ML, Eller LA, Kibuuka H, Rono K, Maganga L, Nitayaphan S, Kroon E, Sawe FK, Sinei S, Sriplienchan S, Jagodzinski LL, Malia J, Manak M, de Souza MS, Tovanabutra S, Sanders-Buell E, Rolland M, Dorsey-Spitz J, Eller MA, Milazzo M, Li Q, Lewandowski A, Wu H, Swann E, O'Connell RJ, Peel S, Dawson P, Kim JH, Michael NL | display-authors = 6 | title = Prospective Study of Acute HIV-1 Infection in Adults in East Africa and Thailand | language = EN | journal = The New England Journal of Medicine | volume = 374 | issue = 22 | pages = 2120–30 | date = June 2016 | pmid = 27192360 | pmc = 5111628 | doi = 10.1056/nejmoa1508952 }}{{Cite web|url=https://www.hjf.org/site/assets/files/1028/hjf_annualreport_2016.pdf|title=HJF Annual Report 2016 | date=2016|website=HJF | access-date= 26 October 2018 }}
Work Outside of HIV
Zika, Ebola, and Middle East Respiratory Syndrome (MERS) outbreaks were responded to by MHRP, as they used their infrastructure and research experience to help develop vaccines for both local people and military personnel living in regions where those diseases were endemic.{{Cite web|url=https://www.hjf.org/site/assets/files/1028/hjf_annualreport_2016.pdf|title=HJF Annual Report 2016 | date=2016|website=HJF | access-date= 26 October 2018 }}
In 2014, MHRP's Uganda site conducted the first vaccine trial for Ebola and Marburg virus ever done in Africa. Using combination DNA vaccines, it was shown that it is safe for people to receive both vaccines in combination. The antigens conduced by these vaccines were critical in the future development of stronger Ebola vaccines in Africa.{{cite journal | vauthors = Kibuuka H, Berkowitz NM, Millard M, Enama ME, Tindikahwa A, Sekiziyivu AB, Costner P, Sitar S, Glover D, Hu Z, Joshi G, Stanley D, Kunchai M, Eller LA, Bailer RT, Koup RA, Nabel GJ, Mascola JR, Sullivan NJ, Graham BS, Roederer M, Michael NL, Robb ML, Ledgerwood JE | display-authors = 6 | title = Safety and immunogenicity of Ebola virus and Marburg virus glycoprotein DNA vaccines assessed separately and concomitantly in healthy Ugandan adults: a phase 1b, randomised, double-blind, placebo-controlled clinical trial | language = English | journal = Lancet | volume = 385 | issue = 9977 | pages = 1545–54 | date = April 2015 | pmid = 25540891 | doi = 10.1016/S0140-6736(14)62385-0 | s2cid = 205975536 | doi-access = free }} In 2015, the Uganda site conducted a uniquely extensive study of Ebola survivors, finding that many were suffering from chronic malaise including hearing and vision loss up to 21 months post-infection.{{cite journal | vauthors = Clark DV, Kibuuka H, Millard M, Wakabi S, Lukwago L, Taylor A, Eller MA, Eller LA, Michael NL, Honko AN, Olinger GG, Schoepp RJ, Hepburn MJ, Hensley LE, Robb ML | display-authors = 6 | title = Long-term sequelae after Ebola virus disease in Bundibugyo, Uganda: a retrospective cohort study | journal = The Lancet.

MHRP scientists under WRAIR developed a Zika vaccine called ZIKV in only ten months,{{Cite web|url=http://www.drugtopics.com/article/human-trials-zika-vaccine-underway|title=Human trials of Zika vaccine underway|last=Blank|first=Christine | name-list-style = vanc |date=November 30, 2016|website=Drug Topics }} beginning clinical trial in 2016. This vaccine is not only important to maintain troop health when deploying to foreign regions where Zika is prevalent, but also for those servicemen stationed domestically because there are clusters of military bases in the southern United States where people are at risk for Zika.{{Cite news|url=https://www.defense.gov/Explore/News/Article/Article/999584/human-trials-begin-for-army-developed-zika-vaccine|title=Human Trials Begin for Army-Developed Zika Vaccine|work=U.S. Department of Defense |access-date=2018-11-07|language=en-US}} Preliminary data from a phase 1 clinical trial indicate that 92% of participants would be protected from Zika infection.
