Adenovirus Type 4 and Type 7 Vaccine Live Oral and XaQuil XR

• Generic Name: adenovirus vaccine
• Dosage Forms: n.a.
• Other Brand Names: Adenovirus Type 4 and Type 7 Vaccine Live Oral

Prevention of febrile acute respiratory disease caused by adenovirus type 4 and type 7. Labeled by FDA for use in military populations 17 through 50 years of age; not commercially available for use in other individuals. (See Restricted Distribution under Dosage and Administration.)

Adenoviruses, especially adenovirus type 4 and type 7, commonly cause acute respiratory disease (e.g., runny nose, fever, sore throat, breathing problems, cough, headache, croup, bronchitis). Certain adenovirus serotypes cause other illnesses (e.g., conjunctivitis, keratoconjunctivitis, otitis media, gastroenteritis, cystitis). Disseminated or life-threatening infections can occur (e.g., severe pneumonia, hepatitis, meningitis, encephalitis). Adenoviruses spread person to person via direct contact, respiratory droplet transmission, or food and/or water contaminated with feces. Fomites also may be involved in transmission since adenoviruses survive for long periods outside of the body, including on environmental surfaces, and are unusually stable when exposed to chemical and physical agents or adverse pH conditions.

Military recruits are at increased risk of acute respiratory illnesses during basic training because of several factors, including close sleeping and training environments where transmission of respiratory pathogens is facilitated, congregation of young adults arriving from wide geographic distributions who may enter basic training carrying pathogens capable of being spread to others who are immunologically susceptible, and stressful nature of basic training and military operations. Adenoviruses, especially adenovirus type 4 and type 7, are a well documented cause of acute respiratory illness in military recruits; adenoviruses reportedly cause 50–80% of cases of acute respiratory disease in this population. Outbreaks of adenovirus-associated disease also occur in other populations (e.g., healthcare-associated outbreaks), but the combination of sustained transmission and relatively high and predictable attack rates of adenovirus-associated respiratory disease appears to be unique to military basic trainees.

US Department of Defense (DOD) requires that all enlisted US military recruits 17 through 50 years of age receive a single dose of adenovirus type 4 and type 7 vaccine live oral at the earliest opportunity upon arrival at initial entry training (basic military training), unless contraindicated (see Contraindications under Cautions). May also be recommended for other military personnel at high risk for adenovirus infection, but not required for cadre working at enlisted basic training sites.

• Generic Name: l-methylfolate

Folate is a form of B vitamin that occurs naturally in many foods. Folic acid is the man-made form of folate that is added to processed foods or vitamin and mineral supplements. Folate is needed in the human body for production of red blood cells.

A lack (deficiency) of folate in the human body can be caused by certain diseases, by taking certain medications, or by not getting enough folate in your diet. Folate deficiency can lead to decreased red blood cells, or anemia. Folate deficiency can also cause high levels of a certain amino acid in the blood, a condition called hyperhomocysteinemia (HYE-per-HOE-moe-sis-tin-EE-mee-a).

XaQuil XR is a medical food for use in people who have conditions related to folate deficiency. This medicine is also used in people with major depressive disorder who have folate deficiency, or in people with schizophrenia who have hyperhomocysteinemia related to folate deficiency.

XaQuil XR is not an antidepressant or anti-psychotic medication. However, this medicine may enhance the effects of antidepressant medications.

XaQuil XR may also be used for purposes not listed in this medication guide.
