The effectiveness of current influenza vaccines varies by strain and season, in part because influenza viruses continuously evolve to evade human immune responses. While the majority of seasonal influenza infections cause relatively mild symptoms, each year influenza virus infections result in over 500,000 hospitalizations in the United States and Europe. Current standard of care for individuals hospitalized with uncomplicated influenza infection is administration of neuraminidase inhibitors.

A plasmid encodes human interleukin-8 (IL-8) receptor CXCR1. IL-8 is a chemo-attractant cytokine that attracts and activates neutrophils in inflammatory regions.

Subarachnoid hemorrhage (SAH) occurs in 28,000 people per year in North America. Symptomatic vasospasm occurs in the majority of individuals suffering SAH and is the most common cause of morbidity and mortality in patients reaching neurological care. Specifically, vasospasm causes cerebral ischemia or stroke, and the prevention of vasospasm could prevent stroke and death as well as allow physicians more freedom in scheduling surgery when the operative risks are lower.

Rabies occurs in more than 150 countries and territories, resulting in at least 55,000 human deaths per year worldwide according to World Health Organization estimates. Rabies is a vaccine-preventable viral disease caused by numerous lyssaviruses that are found in a variety of animal species throughout the world. Rabies virus infects the central nervous system, causing disease in the brain with almost 100% mortality once clinical symptoms manifest.

Antibiotic resistance is one of the world's most pressing health concerns. ß-lactamases, such as carbapenemases, are enzymes produced by bacteria that provide resistance to multiple ß-lactam antibiotics (e.g., penicillins, cephamycins, and carbapenems) by breaking down the antibiotic molecules and deactivating their antibacterial properties. Carbapenems are broad-spectrum antibiotics often prescribed to treat serious infections in hospitalized patients, and infections with carbapenem-resistant Enterobacteriaceae (CRE) have become a challenge in healthcare settings.

Zika virus (ZIKV) can be passed from a pregnant woman to her fetus. Infection during pregnancy can cause microcephaly and other severe birth defects. Currently, there are no vaccines to prevent or medications to treat Zika infections.

The Zika virus (ZIKV) can be passed from a pregnant woman to her fetus. Resulting infection by this virus can cause early miscarriage and a pattern of severe birth defects in fetuses and infants. Therefore, a rapid diagnostic assay that can be performed throughout pregnancy in a clinical setting is vital for prenatal care of women living in areas where this virus may be transmitted.

Zika virus (ZIKV) is a flavivirus primarily transmitted by infected Aedes mosquitoes. Infection with ZIKV during pregnancy can affect the fetus causing microcephaly, neurological complications, and other birth defects. Adults are also at risk of developing Guillain-Barre syndrome and other neurological disorders from ZIKV infection. In response to the 2015-2016 Zika outbreak, CDC researchers developed new Zika virus chimeras that can be used for inactivated Zika vaccine candidates and faster Zika antibody (Ab) neutralization assay testing.

Rotavirus is a highly contagious, diarrhea-inducing pathogen that annually causes approximately 250,000 deaths worldwide and millions of hospitalizations, especially afflicting infants and young children. One strategy to combat this virus is through vaccination. Continuing safety and efficacy concerns with the currently existing live, oral vaccines against rotavirus have led researchers to search for alternative treatment approaches, such as vaccines containing inactivated rotavirus.

Heartland virus (HRTV) is a novel tick-borne virus first discovered in 2009 that causes flu-like symptoms such as fever, headaches, fatigue, muscle aches, and diarrhea. Patients with HRTV often have low white blood cell counts, low platelet counts, and abnormal liver function tests which can become severe. Cases of Heartland virus disease have been identified in the Midwestern and southern United States. There are no vaccines to prevent or medications to treat Heartland virus infections.
