Adenovirus Type 7 (adenovirus vaccine live type-7)

No dosing information is available for this tab.

Adenovirus vaccine is administered orally as 2 separate tablets. One tablet contains the adenovirus type 4 vaccine component and one tablet contains the adenovirus type 7 vaccine component.

Adenovirus vaccine tablets contain live adenovirus inside an enteric coating. The tablets are designed so that they pass through the stomach intact and release live vaccine virus in the intestines. The tablets should be swallowed whole and should not be chewed or crushed. If the tablets are chewed, the adenovirus will be released too soon and could expose the upper respiratory tract to live vaccine virus and result in adenovirus disease.

Store adenovirus vaccine under refrigeration between 2-8degreesC; do not freeze. Keep the bottle tightly closed to protect from moisture and do not remove the desiccant canister from the bottle.

Selected Live Viral Vaccines/Rho Immunoglobulin

SEVERITY LEVEL: 1-Contraindicated Drug Combination: This drug combination is contraindicated and generally should not be dispensed or administered to the same patient.

MECHANISM OF ACTION: Immune globulin products may prevent the immune system from properly responding to the vaccine.(1-6)

CLINICAL EFFECTS: Administration of a live viral vaccine after immunoglobulins may impair the efficacy of the vaccine.(1-6) Administration of immunoglobulins within 2-4 weeks after a live viral vaccine impair the efficacy of the vaccine.(1-6)

PREDISPOSING FACTORS: None determined.

PATIENT MANAGEMENT: Administration of a live viral vaccine should be postponed for three months in patients who have received immunoglobulin therapy, including Rho immunoglobulin.(1-6) If a live viral vaccine is given within two to four weeks of rho immunoglobulin, then repeat vaccination three months after the completion of immunoglobulin should be considered.(2-4)

DISCUSSION: Administration of a live viral vaccine after immunoglobulins(1-6) or administration of immunoglobulins after a live vaccine(3) may impair the efficacy of the vaccine.

Selected Live Viral Vaccines/Selected Immunoglobulins

SEVERITY LEVEL: 1-Contraindicated Drug Combination: This drug combination is contraindicated and generally should not be dispensed or administered to the same patient.

MECHANISM OF ACTION: Immune globulin(IG) products may prevent the immune system from properly responding to the vaccine.(1-19)

CLINICAL EFFECTS: Administration of selected live viral vaccines after immunoglobulins may impair the efficacy of the vaccine.(1-19) Administration of immunoglobulins within 2-4 weeks after selected live viral vaccines impair the efficacy of the vaccine.(1-4,15)

PREDISPOSING FACTORS: The amount of antigen-specific antibody present in the administered immunoglobulin product determines the duration of this interaction.(15)

PATIENT MANAGEMENT: The recommendations regarding this interaction are conflicting. The Centers for Disease Control and Prevention(CDC) immunization recommendations for spacing of live vaccines and antibody-containing products include the following(15): - Live attenuated influenza vaccine, rotavirus, zoster and Ty21a typhoid vaccines may be given any time before, concurrent, with, or after administration of any immune globulin. Yellow fever vaccine may also be given in areas where donor blood products are unlikely to contain a substantial quantity of yellow fever antibody. - Administration of measles or varicella containing vaccines should be postponed for the following intervals after immunoglobulin therapy: Hepatitis B IG, Tetanus IG - 3 months Rabies IG - 4 months Varicella IG - 5 months Measles prophylaxis IG - 6 months if nonimmunocompromised Botulinum IG Intravenous, CMV IG Intravenous, Hepatitis A IG - 6 months Intravenous Immune Globulin(IVIG) - 8 to 11 months depending upon the dose Monoclonal antibody to RSV F protein (palivizumab) - none - Administration of antibody-containing products should be delayed 2 weeks after administration of live vaccines, except for influenza, rotavirus, zoster and typhoid vaccines as noted above. CDC guidelines state that in circumstances where there is high-risk of vaccine-preventable disease, it is acceptable to administer a dose of vaccine prior to completion of these intervals.(16) Manufacturer recommendations are as follows: Administration of a live viral vaccine should be postponed for at least three months in patients who have received the following immunoglobulin therapy: anthrax immunoglobulin,(19) cytomegalovirus immunoglobulin,(1) hepatitis B immunoglobulin,(5,6) rabies immunoglobulin,(7) tetanus immunoglobulin,(8-11) vaccinia immunoglobulin,(18) and zoster immunoglobulin.(2) Administration of a live viral vaccine should be postponed for at least six months in patients who have received the following immunoglobulin therapy: botulinum neurotoxin a/b immune globulin.(17) The US manufacturer of human immunoglobulin states that live viral vaccines should be postponed for three months in patients who have received human immunoglobulin. The Australian and Canadian manufacturers of human immunoglobulin advise postponing live viral vaccines for 3-6 months in patients who have received human immunoglobulin.(6,12,13,18) The UK manufacturer states that vaccines may be compromised for one year and vaccines should be postponed in children for at least seven months.(14) The US manufacturer of immune globulin-hyaluronidase states that immune response to live attenuated vaccines may be impaired for up to 6 months, or for a year or more in the case of measles vaccine.(15) Cytomegalovirus immunoglobulin(1) or human immunoglobulin(3) should not be administered to patients who have received a live vaccine in the previous two weeks. If a live viral vaccine is given within two weeks of zoster immunoglobulin,(1) repetition of the vaccination three months after the completion of immunoglobulin should be considered.

DISCUSSION: CDC Immunization Recommendations(15)provide discussion, charts, and further details regarding appropriate use and timing of vaccine therapy.(16)

Vaccines/Pariglasgene Brecaparvovec

SEVERITY LEVEL: 1-Contraindicated Drug Combination: This drug combination is contraindicated and generally should not be dispensed or administered to the same patient.

MECHANISM OF ACTION: Pariglasgene brecaparvovec therapy may decrease the effectiveness of vaccines. The mechanism is not known.(1)

CLINICAL EFFECTS: The expected serum antibody response may not be obtained.(1)

PREDISPOSING FACTORS: None determined.

PATIENT MANAGEMENT: The US manufacturer of pariglasgene brecaparvovec states that vaccines should be avoided for 1 month prior to pariglasgene brecaparvovec administration.(1)

DISCUSSION: Pariglasgene brecaparvovec therapy may decrease the effectiveness of vaccines.(1)

Severe Interaction: Action is required to reduce the risk of severe adverse interaction.

Live Vaccines/Brensocatib

SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction.

MECHANISM OF ACTION: Brensocatib may suppress the immune system by inhibiting dipeptidyl peptidase-1 (DPP-1). Brensocatib prevents the activation of neutrophil serine proteases (NSPs) during neutrophil maturation in the bone marrow.(1) Immunocompromised patients may be at increased risk for uninhibited replication after administration of live, attenuated vaccines. Immune response to vaccines may be decreased during periods of immunocompromise.(2)

CLINICAL EFFECTS: The expected serum antibody response may not be obtained. The vaccine may result in illness. Immune response to live vaccines may be decreased during periods of immunocompromise.(2)

PREDISPOSING FACTORS: Immunosuppressive diseases (e.g. hematologic malignancies, HIV disease), treatments (e.g. radiation) and drugs may all increase the magnitude of immunodeficiency.

PATIENT MANAGEMENT: The coadministration of live vaccines and brensocatib should be avoided.(1) The Centers for Disease Control (CDC) Advisory Committee on Immunization Practices (ACIP) states that live-virus and live-attenuated vaccines should not be administered to patients who are immunocompromised. The magnitude of immunocompromise and associated risks should be determined by a physician.(2)

DISCUSSION: Killed or inactivated vaccines do not pose a danger to immunocompromised patients.(2) The concomitant use of live attenuated vaccines and brensocatib has not been evaluated. Brensocatib may suppress the immune system by inhibiting dipeptidyl peptidase-1 (DPP-1).(1)

Live Vaccines/Leniolisib

SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction.

MECHANISM OF ACTION: Leniolisib modifies the immune system. Immune response to live vaccines may be decreased during treatment with leniolisib.(1)

CLINICAL EFFECTS: The expected serum antibody response may not be obtained.(1)

PREDISPOSING FACTORS: Immunosuppressive diseases (e.g. hematologic malignancies, HIV disease), treatments (e.g. radiation) and drugs may all increase the magnitude of immunodeficiency.

PATIENT MANAGEMENT: The manufacturer of leniolisib states live, attenuated vaccinations may be less effective if administered during leniolisib treatment.(1)

DISCUSSION: Killed or inactivated vaccines do not pose a danger to immunocompromised patients.(1)

Live Vaccines/Methotrexate (LOW STRENGTH INJECTION, ORAL)

SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction.

MECHANISM OF ACTION: A variety of disease modifying agents such as methotrexate suppress the immune system. Immunocompromised patients may be at increased risk for uninhibited replication after administration of live, attenuated vaccines. Immune response to vaccines may be decreased during periods of immunocompromise.(1)

CLINICAL EFFECTS: The expected serum antibody response may not be obtained and/or the vaccine may result in illness.(1)

PREDISPOSING FACTORS: Immunosuppressive diseases (e.g. hematologic malignancies, HIV disease), treatments (e.g. radiation) and drugs may all increase the magnitude of immunodeficiency.

PATIENT MANAGEMENT: The Centers for Disease Control(CDC) Advisory Committee on Immunization Practices (ACIP) states that live-virus and live, attenuated vaccines should not be administered to patients who are immunocompromised. The magnitude of immunocompromise and associated risks should be determined by a physician.(1) CDC recommendations for zoster vaccine state it may be administered to patients receiving methotrexate if the dose is < or = to 0.4 mg/kg/week for treatment of rheumatoid arthritis, psoriasis, inflammatory bowel disease or other conditions.(1) For patients scheduled to receive chemotherapy, vaccination should ideally precede the initiation of chemotherapy by 14 days. Patients vaccinated while on immunosuppressive therapy or in the 2 weeks prior to starting therapy should be considered unimmunized and should be revaccinated at least 3 months after discontinuation of therapy.(1)

DISCUSSION: Killed or inactivated vaccines do not pose a danger to immunocompromised patients.(1) Patients with a history of leukemia who are in remission and have not received chemotherapy for at least 3 months are not considered to be immunocompromised.(1)

Live Vaccines/Systemic Corticosteroids; Corticotropin (ACTH)

SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction.

MECHANISM OF ACTION: Corticosteroids and corticotropin suppress the immune system. In severely immunocompromised patients, virus replication after administration of live, attenuated-virus vaccines can be enhanced and/or the immune response to the vaccine may be decreased.(1)

CLINICAL EFFECTS: The expected serum antibody response may not be obtained and/or the vaccine may result in illness.(1)

PREDISPOSING FACTORS: Patients receiving immunosuppressive doses of corticosteroids or corticotropin for equal to or greater than 14 consecutive days.(1)

PATIENT MANAGEMENT: The Centers for Disease Control's (CDC) Advisory Committee on Immunization Practices (ACIP) states that live-virus and live, attenuated vaccines should not be administered to patients who are severely immunosuppressed, including those who are receiving or have received high-dose, systemic steroids for greater than or equal to 14 consecutive days. Live vaccines should be deferred for at least 1 month after discontinuation of high-dose systemic steroids administered for 14 consecutive days. When initiating immunosuppressives doses of corticosteroids, wait 4 weeks after a live vaccines is administered. However, if patients require therapy for chronic inflammatory conditions, do not delay therapy due to past vaccines. Patients who are vaccinated within the 14 days prior to initiating immunosuppressive therapy should be considered unvaccinated and should be revaccinated at least 3 months after immunosuppressive therapy is discontinued.(1) The US manufacturer of corticotropin(2) and triamcinolone(3) and the Australian manufacturer of dexamethasone(4) state that administration of live or live-attenuated vaccines is contraindicated in patients receiving immunosuppressive doses of corticosteroids or corticotropin. The manufacturer of deflazacort states that live or live-attenuated vaccines should be administered at least 4 to 6 weeks prior to initiation of therapy with deflazacort.(5)

DISCUSSION: Many clinicians consider a dose equivalent to either 2 mg/kg of body weight or a total of 20 mg/day of prednisone as sufficiently immunosuppressive to raise safety concerns about live-virus vaccines.(1) Immunization procedures may be undertaken in patients receiving corticosteroids when the therapy is short term (less than 2 weeks); low to moderate dose; long-term, alternate-day treatment with short-acting preparations; maintenance physiologic doses (replacement therapy); or administered topically (skin or eyes), by aerosol, or by intra-articular, bursal, or tendon injection.(1) Killed or inactivated vaccines do not pose a danger to immunocompromised patients.(1)

Live Vaccines/Tuberculin Testing

SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction.

MECHANISM OF ACTION: Measles infection and severe acute and chronic infections may induce an anergic state resulting in a false-negative tuberculin test. The live measles vaccine, as well as other live vaccines (e.g. smallpox, varicella, yellow fever) theoretically may also suppress response to tuberculin testing, though the degree of suppression may be less than that expected from acute infection with wild-type virus.(1-4)

CLINICAL EFFECTS: Tuberculin testing that is performed more than one day but less than 28 days after administration of a live vaccine may result in a false negative tuberculin response. Tuberculin testing may be administered simultaneously with live vaccines.(1-4)

PREDISPOSING FACTORS: None determined.

PATIENT MANAGEMENT: The CDC states that live vaccines (e.g. MMR and varicella) and tuberculin testing may be administered within one day of each other at separate administration sites. If it has been more than one day since tuberculin testing has been administered, the live vaccine can be given at any interval after the tuberculin test. However, if the live vaccine has been administered more than one day previously and tuberculin testing is indicated, tuberculin testing should be deferred for at least 4-6 weeks.(1-4)

DISCUSSION: Suppression of response to tuberculin testing has been observed following measles infection, live measles vaccination, and live smallpox vaccination. The degree of suppression after live virus vaccination is likely to be less than that from an acute infection with wild-type virus. There is no data on suppression of response to tuberculin testing with other live vaccines. In the absence of data, the CDC recommends tuberculin testing within one day that a live vaccine is administered. Otherwise the tuberculin test should be deferred for at least 4-6 weeks.(1-4)

Live Vaccines; Live Bcg/Hydroxyurea

SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction.

MECHANISM OF ACTION: Hydroxyurea may suppress the immune system.(1) Immunocompromised patients may be at increased risk for uninhibited replication after administration of live, attenuated vaccines or intravesicular BCG. Immune response to vaccines may be decreased during periods of immunocompromise.(2)

CLINICAL EFFECTS: The expected serum antibody response may not be obtained and/or the vaccine may result in illness.(2) After instillation of intravesicular BCG, immunosuppression may interfere with local immune response, or increase the severity of mycobacterial infection following inadvertent systemic exposure.(3)

PREDISPOSING FACTORS: Immunosuppressive diseases (e.g. hematologic malignancies), treatments (e.g. radiation) and cytotoxic drugs may all increase the magnitude of immunodeficiency.

PATIENT MANAGEMENT: Recommendations for administration of live vaccines in patients on hydroxyurea are dependent on the indication. The US manufacturers of hydroxyurea recommend avoiding live vaccine use in patients taking hydroxyurea. Evaluate hematologic status prior to and during treatment with hydroxyurea. Provide supportive care and modify the dose or discontinue hydroxyurea as needed.(1) The Centers for Disease Control (CDC) Advisory Committee on Immunization Practices (ACIP) states that live-virus and live, attenuated vaccines should not be administered to patients who are immunocompromised. The magnitude of immunocompromise and associated risks should be determined by a physician. Patients who are vaccinated within the 14 days prior to initiating immunosuppressive therapy should be considered unvaccinated and should be revaccinated at least 3 months after immunosuppressive therapy is discontinued.(2) The ACIP recommendations state that routine vaccinations patients with secondary immunodeficiency such as sickle cell disease are likely effective. Live viral and bacterial vaccines are contraindicated in patients with generalized malignant neoplasm, immunosuppressive, or radiation therapy, depending on immune status.(4)

DISCUSSION: Killed or inactivated vaccines do not pose a danger to immunocompromised patients.(2) Patients with a history of leukemia who are in remission and have not received chemotherapy for at least 3 months are not considered to be immunocompromised.(2) A multicenter, randomized, double-blind, placebo-controlled trial in infants and young children with sickle cell disease (BABY HUG) studied the response to pneumococcal and measles, mumps, and rubella vaccines in patients using hydroxyurea. The authors concluded that hydroxyurea does not appear to have significant deleterious effects on the immune function of infants and children with sickle cell disease. Additional assessments of lymphocyte parameters of hydroxyurea-treated children may be warranted. No changes in current immunization schedules are recommended; however, for endemic disease or epidemics, adherence to accelerated immunization schedules for the measles, mumps, and rubella vaccine should be reinforced.(5)

Live Vaccines; Live Bcg/Teplizumab

SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction.

MECHANISM OF ACTION: Teplizumab may cause lymphopenia and suppress the immune system. Immunocompromised patients may be at increased risk for uninhibited replication after administration of live, attenuated vaccines or intravesicular BCG. Immune response to vaccines may be decreased during periods of immunocompromise.(1,2)

CLINICAL EFFECTS: The expected serum antibody response may not be obtained. The vaccine may result in illness.(1,2) After instillation of intravesicular BCG, immunosuppression may interfere with local immune response, or increase the severity of mycobacterial infection following inadvertent systemic exposure.(3)

PREDISPOSING FACTORS: Immunosuppressive diseases (e.g. hematologic malignancies, HIV disease), treatments (e.g. radiation) and drugs may all increase the magnitude of immunodeficiency.

PATIENT MANAGEMENT: The Centers for Disease Control (CDC) Advisory Committee on Immunization Practices (ACIP) states that live-virus and live-attenuated vaccines should not be administered to patients who are immunocompromised. The magnitude of immunocompromise and associated risks should be determined by a physician.(1) Vaccination should ideally precede the initiation of teplizumab therapy by 8 weeks. Live vaccines are not recommended within the 8 weeks prior to, during, or for 52 weeks after stopping teplizumab therapy.(2)

DISCUSSION: Vaccinations may be less effective if administered within 8 weeks before, during, and for 52 weeks following teplizumab therapy.(2) Killed or inactivated vaccines do not pose a danger to immunocompromised patients.(1)

Moderate Interaction: Assess the risk to the patient and take action as needed.

Vaccines/Hepatitis B Vaccine (FENDRIX)

SEVERITY LEVEL: 3-Moderate Interaction: Assess the risk to the patient and take action as needed.

MECHANISM OF ACTION: No data is available on the concurrent administration of the hepatitis B vaccine Fendrix and other vaccines.(1)

CLINICAL EFFECTS: It is unknown if concurrent administration of the hepatitis B vaccine Fendrix and other vaccines will affect the efficacy of either vaccine.(1)

PREDISPOSING FACTORS: None determined.

PATIENT MANAGEMENT: The Swedish manufacturer of Fendrix states that since there is no data available for the concurrent administration of Fendrix with other vaccines, the administration of Fendrix and other vaccines should be separated by 2 to 3 weeks.(1)

DISCUSSION: No data is available on the concurrent administration of the hepatitis B vaccine Fendrix with other vaccines.(1)

Safety and efficacy of adenovirus vaccine have not been established in infants and children younger than 17 years of age.

Adenovirus vaccine is contraindicated in pregnant women, and pregnancy should be avoided by using effective contraception for at least 6 weeks after vaccination. Females of reproductive potential should receive a pregnancy test prior to receipt of the vaccine.

Naturally occurring adenovirus infection has been associated with fetal harm. It is not known whether adenovirus vaccine can cause fetal harm when administered to a pregnant woman or affect reproduction capacity.

There were 5 pregnancies reported among women enrolled in a clinical study that evaluated use of adenovirus vaccine in US military recruits 17 years of age and older. Four of these women (3 vaccine recipients and 1 placebo recipient) were estimated to have conceived 2-13 days prior to vaccination; the other woman (vaccine recipient) conceived approximately 21 weeks after vaccination. All 5 women delivered healthy infants with estimated gestational ages of 36-40 weeks.

Data are not available regarding the effect of adenovirus vaccine on labor and delivery. Vaccine virus shed in stools during delivery may result in transmission of the vaccine virus to the neonate.

There are no data on the presence of adenovirus vaccine in human milk, effects on milk production, or on the breastfed infant following administration.

Consider the developmental and health benefits of breast-feeding along with the mother's clinical need for the vaccine and any potential adverse effects on the breast-fed infant from the vaccine or from the underlying maternal condition.

Adenovirus vaccine is not indicated in adults older than 50 years of age, including geriatric adults.

Safety and efficacy of adenovirus vaccine have not been established in adults 65 years of age or older.

Clinical studies evaluating adenovirus vaccine did not include individuals 65 years of age or older, and data are not available to determine whether geriatric individuals respond differently than younger adults.
