Adenovirus Type 4 and Type 7 Vaccine Live Oral Dosage and Administration


Restricted Distribution

Developed specifically for use in military populations.4 Labeled by FDA for use in military populations 17 through 50 years of age;1 not available for use in other populations.14


Oral Administration

Administer orally as 2 separate tablets:1 one tablet containing adenovirus type 4 vaccine component and one tablet containing adenovirus type 7 vaccine component.1

Tablets contain live adenovirus inside an enteric coating;1 designed to pass through stomach intact and release live vaccine virus in the intestine.1 Swallow tablets whole; do not chew or crush.1 7 If tablets are chewed, adenovirus will be released too soon and could expose the upper respiratory tract to live vaccine virus and result in adenovirus disease.1 7

To facilitate swallowing of vaccine tablets and reduce risk of inadvertent chewing, ingest the tablets with a small amount of water.7 Both vaccine tablets may be swallowed at the same time or swallowed separately, one after the other, whichever is easier to accomplish without chewing.7

If vaccine tablets are accidentally chewed, clear the vaccine from the mouth by swishing and swallowing several sips of water, followed by swishing antiseptic mouthwash for 30 seconds and then spitting the used mouthwash into a container.7 Consider the used mouthwash biohazardous material and handle and dispose of according to local guidelines.7 Advise individuals who inadvertently chew tablets to seek medical care if they develop symptoms of fever or respiratory infection and to inform their clinician about the chewed tablets.7

Defer administration of vaccine tablets in individuals with vomiting and/or diarrhea.1 4 5 (See Concomitant Illness under Cautions.)

May be given simultaneously with or at any interval before or after other vaccines.5 134 (See Vaccines under Interactions.)

Interactions for Adenovirus Type 4 and Type 7 Vaccine Live Oral

Specific Drugs




Immunosuppressive agents (e.g., alkylating agents, antimetabolites, corticosteroids, radiation)

Potential for diminished or suboptimal antibody response to vaccines134

Live viral vaccines generally contraindicated in those receiving high dosages of systemic corticosteroids or when immunosuppression occurs with prolonged topical corticosteroid therapy134

Optimum interval between discontinuance of immunosuppressive therapy and subsequent administration of a live viral vaccine not determined;134 generally defer live viral vaccines for at least 3 months after immunosuppressive therapy discontinued, including chemotherapy or radiation for leukemia, other hematopoietic malignancies, or solid tumors, or after solid organ transplant134

Systemic corticosteroid therapy (prednisone or equivalent) in a dosage ≥2 mg/kg daily or ≥20 mg daily given for ≥2 weeks is considered immunosuppressive;134 delay administration of live viral vaccines for at least 1 month after such therapy discontinued134

Corticosteroid therapy involving short-term (<2 weeks), low- to moderate-dose systemic therapy (<20 mg prednisone or equivalent daily); long-term, alternate-day systemic therapy using short-acting drugs; maintenance physiologic doses (replacement therapy); topical therapy (e.g., cutaneous, ophthalmic); inhalation; or intra-articular, bursal, or tendon injections generally does not contraindicate use of live viral vaccines134
