(Typhoid Vaccine Live Oral Ty21a)
Important Safety Information1
Vivotif (Typhoid Vaccine Live Oral Ty21a) is indicated for immunization of adults and children greater than 6 years of age against disease caused by Salmonella Typhi. Routine typhoid vaccination is not recommended in the United States of America. Selective immunization against typhoid fever is recommended for the following groups: 1) travelers to areas in which there is a recognized risk of exposure to S Typhi; 2) persons with intimate exposure (eg, household contact) to an S Typhi carrier; and 3) microbiology laboratorians who work frequently with S Typhi. There is no evidence to support the use of typhoid vaccine to control common source outbreaks, disease following natural disasters, or in persons attending rural summer camps.
Vivotif (Typhoid Vaccine Live Oral Ty21a) should not be administered to persons with a hypersensitivity to any component of the vaccine or the enteric-coated capsule. The vaccine should not be administered to persons during an acute febrile illness. Safety of the vaccine has not been demonstrated in persons deficient in their ability to mount a humoral or cell-mediated immune response, due to either a congenital or acquired immunodeficient state including treatment with immunosuppressive or antimitotic drugs. The vaccine should not be administered to these persons regardless of benefits.
Vivotif is not to be taken during an acute gastrointestinal illness. The vaccine should not be administered to individuals receiving sulfonamides and antibiotics since these agents may be active against the vaccine strain and prevent a sufficient degree of multiplication to occur in order to induce a protective immune response. Postpone taking the vaccine if persistent diarrhea or vomiting is occurring. Unless a complete immunization schedule is followed, an optimum immune response may not be achieved. Not all recipients of Vivotif will be fully protected against typhoid fever. Vaccinated individuals should continue to take personal precautions against exposure to typhoid organisms, ie, travelers should take all necessary precautions to avoid contact or ingestion of potentially contaminated food or water.
The health care provider should take all necessary precautions to ensure safe and effective use of the vaccine. Patients should be questioned about previous reactions to this or similar products. The previous immunization history of the patient and current antibiotic usage should be obtained by the health care provider.
