Drug Interactions

Abatacept: (Contraindicated) If possible, administer all needed vaccines before abatacept initiation. Live vaccines should not be given concurrently with abatacept or within 3 months of its discontinuation. The immune response of the immunocompromised patient to vaccines may be decreased and adjusted doses or boosters that are more frequent may be required. The immune response to an inactive vaccine may still be suboptimal. Live virus vaccines may induce the illness they are intended to prevent and are contraindicated for use during immunosuppressive treatment. If immunization is necessary, choose an alternative to live vaccination, or, consider a delay or change in the immunization schedule. Practitioners should refer to the most recent CDC guidelines regarding vaccination of patients who are receiving drugs that adversely affect the immune system.
Abrocitinib: (Contraindicated) Avoid administration of live virus vaccines with immunosuppressive drug therapy and prior to immune recovery following treatment with immunosuppressive drug therapy. When feasible, administer indicated live virus vaccines at least four weeks before planned immunosuppression or wait until at least three months after discontinuation. The time to restoration of immune competence may be longer in some patients. Patients with altered immunocompetence may be at increased risk for severe adverse reactions due to uninhibited growth of the attenuated live virus. Additionally, vaccines may be less effective if administered during a period of altered immunocompetence.
Acetaminophen; Aspirin, ASA; Caffeine: (Major) No adverse events associated with the use of salicylates after varicella vaccination have been reported. However, the manufacturer of varicella virus vaccine live recommends the avoidance of salicylates or aspirin, ASA use for 6 weeks after vaccination. Reye's syndrome, which exclusively affects children under 15 years old, has been associated with aspirin use following active varicella infection. Vaccination with close clinical monitoring is recommended for children who require therapeutic aspirin, ASA therapy; according to the CDC the use of attenuated, live varicella virus vaccine is thought to present less risk than natural varicella disease to such children.
Acetaminophen; Aspirin: (Major) No adverse events associated with the use of salicylates after varicella vaccination have been reported. However, the manufacturer of varicella virus vaccine live recommends the avoidance of salicylates or aspirin, ASA use for 6 weeks after vaccination. Reye's syndrome, which exclusively affects children under 15 years old, has been associated with aspirin use following active varicella infection. Vaccination with close clinical monitoring is recommended for children who require therapeutic aspirin, ASA therapy; according to the CDC the use of attenuated, live varicella virus vaccine is thought to present less risk than natural varicella disease to such children.
Acetaminophen; Aspirin; Diphenhydramine: (Major) No adverse events associated with the use of salicylates after varicella vaccination have been reported. However, the manufacturer of varicella virus vaccine live recommends the avoidance of salicylates or aspirin, ASA use for 6 weeks after vaccination. Reye's syndrome, which exclusively affects children under 15 years old, has been associated with aspirin use following active varicella infection. Vaccination with close clinical monitoring is recommended for children who require therapeutic aspirin, ASA therapy; according to the CDC the use of attenuated, live varicella virus vaccine is thought to present less risk than natural varicella disease to such children.
Acyclovir: (Major) If possible, discontinue acyclovir at least 24 hours before administration of the varicella-zoster virus vaccine, live. In patients with HIV, guidelines recommend waiting at least 72 hours after the last dose of acyclovir before administering varicella vaccines. Also, do not administer acyclovir for at least 14 days after vaccination. Concurrent administration of any of the varicella-zoster virus vaccines (Zostavax, Varivax, ProQuad) with antiviral medications known to be effective against varicella zoster virus has not been evaluated. Therefore, when possible, a washout period between the use of the antiviral medication and the vaccines is recommended. Acyclovir has a relatively short serum half-life and is quickly cleared from the body. Refer to the most recent Center for Disease control guidance if concurrent use is necessary.
Adalimumab: (Contraindicated) Do not administer live vaccines to adalimumab recipients; no data are available regarding the risk of secondary transmission of infection by live vaccines in patients receiving adalimumab. Before initiation of adalimumab therapy, consider completion of all age appropriate vaccinations per current immunization guidelines. Adalimumab recipients may receive inactivated vaccines, but the immune response to vaccines or toxoids may be decreased.
Albuterol; Budesonide: (Contraindicated) Avoid the administration of live virus vaccines with high-dose corticosteroid therapy and for at least 1 month following treatment. High-dose corticosteroid therapy is generally defined as a dose of at least 20 mg/day of prednisone or equivalent (or 2 mg/kg/day for patients weighing less than 10 kg) for at least 14 consecutive days. When feasible, administer indicated live virus vaccines at least 4 weeks before planned high-dose corticosteroid therapy or wait at least 1 month after discontinuation. Patients with altered immunocompetence may be at increased risk for severe adverse reactions due to uninhibited growth of the attenuated live virus. Additionally, vaccine efficacy may be diminished in patients receiving any supraphysiologic dose of corticosteroid.
Aldesleukin, IL-2: (Contraindicated) Aldesleukin, IL-2 is associated with impaired neutrophil function. Live virus vaccines should generally not be administered to an immunosuppressed patient. Live virus vaccines may induce the illness they are intended to prevent and are generally contraindicated for use during immunosuppressive treatment. The immune response of the immunocompromised patient to vaccines may be decreased, even despite alternate vaccination schedules or more frequent booster doses. If immunization is necessary, choose an alternative to live vaccination, or, consider a delay or change in the immunization schedule. Practitioners should refer to the most recent CDC guidelines regarding vaccination of patients who are receiving drugs that adversely affect the immune system.
Alemtuzumab: (Contraindicated) Do not administer live vaccines to alemtuzumab recipients; no data are available regarding the risk of secondary transmission of infection by live vaccines in patients receiving alemtuzumab. At least 6 weeks before initiation of alemtuzumab therapy, consider completion of all age appropriate vaccinations per current immunization guidelines. Alemtuzumab recipients may receive inactivated vaccines, but the immune response to vaccines or toxoids may be decreased.

Upadacitinib: (Major) Avoid use of live vaccines during or immediately prior to upadacitinib therapy initiation. Before initiating upadacitinib, it is recommended that patients be brought up to date with all immunizations, including varicella zoster or prophylactic herpes zoster vaccinations, in agreement with current vaccination guidelines.
Ustekinumab: (Contraindicated) If possible, administer all recommended vaccines before ustekinumab initiation. Ustekinumab recipients may receive inactive vaccines, but the elicited immune response may be insufficient to prevent disease. Do not administer live vaccines to a ustekinumab recipient. Furthermore, do not administer BCG live vaccines for either 1 year before or 1 year after ustekinumab receipt, due to the infectious risk for Mycobacteria. No data are available on the response to live vaccination or on the risk of infection or infection transmission after the administration of other live vaccines to ustekinumab recipients. Cautious administration of ustekinumab to household contacts of ustekinumab recipients may be warranted due to the potential risk for shedding from the household contact and transmission to the patient. Practitioners should also refer to the most recent CDC guidelines regarding vaccination of patients who are receiving drugs that adversely affect the immune system.
Vaccinia Immune Globulin, VIG: (Major) Defer vaccination with live attenuated virus vaccines until approximately 3 months after administration of vaccinia immune globulin (VIG). Inform the immunizing physician of recent therapy with the immune globulin so that appropriate measures can be taken. The efficacy of live attenuated virus vaccines may be impaired by vaccinia immune globulin (VIG) administration; revaccination may be necessary. The passive transfer of antibodies from the immune globulin may impair the efficacy of live attenuated virus vaccines.
Valacyclovir: (Major) If possible, discontinue valacyclovir at least 24 hours before administration of the varicella-zoster virus vaccine, live. In patients with HIV, guidelines recommend waiting at least 72 hours after the last dose of valacyclovir before administering varicella vaccines. Also, do not administer valacyclovir for at least 14 days after vaccination. Concurrent administration of any of the varicella-zoster virus vaccines (Zostavax, Varivax, ProQuad) with antiviral medications known to be effective against varicella zoster virus has not been evaluated. Therefore, when possible, a washout period between the use of the antiviral medication and the vaccines is recommended. Valacyclovir has a relatively short serum half-life and is quickly cleared from the body. Refer to the most recent Center for Disease control guidance if concurrent use is necessary.
Vamorolone: (Contraindicated) Avoid the administration of live virus vaccines with high-dose corticosteroid therapy and for at least 1 month following treatment. High-dose corticosteroid therapy is generally defined as a dose of at least 20 mg/day of prednisone or equivalent (or 2 mg/kg/day for patients weighing less than 10 kg) for at least 14 consecutive days. When feasible, administer indicated live virus vaccines at least 4 weeks before planned high-dose corticosteroid therapy or wait at least 1 month after discontinuation. Patients with altered immunocompetence may be at increased risk for severe adverse reactions due to uninhibited growth of the attenuated live virus. Additionally, vaccine efficacy may be diminished in patients receiving any supraphysiologic dose of corticosteroid.
Vedolizumab: (Major) Avoid administering live vaccines to vedolizumab recipients unless the benefits outweigh the risks; no data are available regarding the risk of secondary transmission of infection by live vaccines in patients receiving vedolizumab. Before initiation of vedolizumab therapy, consider completion of all age appropriate vaccinations per current immunization guidelines. Vedolizumab recipients may receive inactivated vaccines, but the immune response to vaccines or toxoids may be decreased.
Venetoclax: (Major) Avoid live vaccines to venetoclax recipients; no data are available regarding the risk of secondary transmission of infection by live vaccines in patients receiving venetoclax. Before initiation of venetoclax therapy, consider completion of all age appropriate vaccinations per current immunization guidelines. Venetoclax recipients may receive inactivated vaccines, but the immune response to vaccines or toxoids may be decreased.
Vincristine Liposomal: (Contraindicated) Do not administer live vaccines to vincristine recipients; no data are available regarding the risk of secondary transmission of infection by live vaccines in patients receiving vincristine. At least 2 weeks before initiation of vincristine therapy, consider completion of all age appropriate vaccinations per current immunization guidelines. Vincristine recipients may receive inactivated vaccines, but the immune response to vaccines or toxoids may be decreased.
Vincristine: (Contraindicated) Do not administer live vaccines to vincristine recipients; no data are available regarding the risk of secondary transmission of infection by live vaccines in patients receiving vincristine. At least 2 weeks before initiation of vincristine therapy, consider completion of all age appropriate vaccinations per current immunization guidelines. Vincristine recipients may receive inactivated vaccines, but the immune response to vaccines or toxoids may be decreased.
Vinorelbine: (Contraindicated) Do not administer live vaccines to vinorelbine recipients; no data are available regarding the risk of secondary transmission of infection by live vaccines in patients receiving vinorelbine. Before initiation of vinorelbine therapy, consider completion of all age appropriate vaccinations per current immunization guidelines. Vinorelbine recipients may receive inactivated vaccines, but the immune response to vaccines or toxoids may be decreased.
Voclosporin: (Major) Live virus vaccines should generally not be administered to an immunosuppressed patient. Live virus vaccines may induce the illness they are intended to prevent and are generally contraindicated for use during immunosuppressive treatment. The immune response of the immunocompromised patient to vaccines may be decreased, even despite alternate vaccination schedules or more frequent booster doses. If immunization is necessary, choose an alternative to live vaccination, or, consider a delay or change in the immunization schedule. Practitioners should refer to the most recent CDC guidelines regarding vaccination of patients who are receiving drugs that adversely affect the immune system.

Mechanism Of Action

Vaccination with varicella-zoster virus vaccine, live produces a detectable IgG antibody humoral immune response in a high proportion of individuals and is well tolerated. Vaccinated patients also have a cell-mediated immune response, consisting of an expression of varicella-zoster specific activation of both CD4+ T-helper and CD8+ T-lymphocytes.
 
Varivax: The significance of humoral immunity and cell-mediated immunity in providing protection against chickenpox is unknown, but patients who do not seroconvert after vaccination still receive some protection from infection via cellular immunity. Vaccination appears to prevent severe disease even in patients who do not seroconvert. The severity of breakthrough chickenpox does not appear to be affected by the length of time since immunization; cases seen 8 years post-varicella virus vaccination still remain mild. Vaccine post-market surveillance suggests there may be a lower incidence rate of herpes zoster after varicella-zoster virus vaccination, live than occurs after natural varicella infection, but longer epidemiologic surveillance is needed to support these findings.
 
Zostavax: The risk of developing herpes zoster appears to be related to a decline in varicella-zoster virus (VZV)-specific immunity. Boosting the VZV-specific cell-mediated immunity is thought to be the mechanism by which varicella-zoster virus vaccine, live protects against herpes zoster and its complications. Overall, vaccine recipients had fewer cases of herpes zoster (5.4 cases per 1000 person-years) than placebo recipients (11.1 cases per 1000 person-years). The number of cases per 1000 person years for the age groups 60—69, 70—79, and greater than 80 years was fairly similar (10.8—12.2). In contrast, the vaccine provided greater protection against herpes zoster development in younger versus older adults. For example, there were 3.9 cases per 1000 person-years among 60—69 year olds, 6.7 cases per 1000 person-years among 70—79 year olds, and 9.9 cases per 1000 person-years among patients at least 80 years of age. Although the vaccine prevented more cases of herpes zoster in younger adults, the likelihood of postherpetic neuralgia (PHN), defined as at least 3 out of 10 pain severity occurring or persisting at least 90 days after rash onset, was lower among older adults who developed herpes zoster. For example, 6.6% of vaccine recipients with herpes zoster had PHN, and 6.9% of placebo recipients had the event among 60—69 year-olds. The respective numbers for 70—79 year-olds are 7.7% and 17.2%, and among patients at least 80 years of age, 18.9% of vaccine recipients and 25.5% of placebo recipients had PHN. The median duration of clinically significant pain was 20 days in vaccine recipients and 22 days in placebo recipients with confirmed cases of herpes zoster. Further, the overall percentages of herpes zoster cases with PHN were lower among vaccine recipients (8.6%) as compared with placebo recipients (12.5%).

Pharmacokinetics

The varicella-zoster virus vaccine, live is administered subcutaneously or intramuscularly. A single dose administered to patients 13 years and older induced seroconversion in 75% of vaccine recipients after 4 weeks. A second dose administered 4 weeks after the first dose increased the seroconversion rate to 99%. In another study, adults and adolescents were administered 2 vaccinations 8 weeks apart. The seroconversion rates were 94% at 6 weeks after the first dose and 99% 6 weeks after the second. The duration of protection is unknown; however, IgG antibodies to varicella after vaccination persist at high concentrations for at least 10 years and are boosted by exposure to natural varicella infection.[28336]

Pregnancy And Lactation
Pregnancy

Varicella-zoster virus vaccine, live is contraindicated for use during pregnancy. No adequate and well-controlled studies have been undertaken, and it is not known if the vaccine can cause fetal harm or affect reproductive capacity. Although no congenital abnormalities were identified in infants born to 928 women inadvertent exposed to a varicella containing vaccine during pregnancy or within 3 months of conception, naturally occurring varicella zoster virus infection is known to sometimes cause fetal harm. Therefore, the manufacturer recommends that varicella virus vaccine live not be administered during pregnancy or within the three months before becoming pregnant. Also, pregnant women without a documented history of chickenpox or laboratory evidence of prior infection should avoid contact with anyone who received the varicella virus vaccine live within the past 6 weeks. Vaccine recipients could spread the virus to others. Females of childbearing potential should be counseled on the recommendation for the use of adequate contraception for 3 months following each dose of varicella virus vaccine live. The CDC recommends avoidance of vaccination of women who are pregnant or might become pregnant within 4 weeks of receiving the vaccine, assessment of pregnant women for evidence of varicella immunity, and administration of dose 1 of the varicella vaccine upon completion or termination of pregnancy and before discharge from the health-care facility to women who do not have evidence of immunity; administer dose number two 4—8 weeks after dose one. NOTE: Vaccine recipients should not be around susceptible, high-risk people for 6 weeks. High-risk, susceptible people include all newborns born at < 28 weeks gestation regardless of maternal varicella immunity and newborns of mothers without a documented history of chickenpox or laboratory evidence of prior infection. Vaccinees and health care providers are encouraged to report any exposure to the vaccine during pregnancy or within 3 months of conception by calling 877—888—4231 or 800—822—7967, or by visiting the VAERS website.

The manufacturer advises caution when administering the varicella-zoster virus vaccine, live to lactating women; however according to the Advisory Committee on Immunization Practices (ACIP), live virus vaccines do not adversely affect the safety of breast-feeding for mothers or their nursing infants. Health care providers are advised that, although attenuated, the potential of transmitting live viruses to the infant through breast milk exists. Definitive data regarding excretion of the varicella vaccine virus into breast milk are not available; however, one small study found no evidence of the virus in 217 post-vaccination breast milk samples. Consider the benefits of breast-feeding, the risk of potential infant drug exposure, and the risk of an untreated or inadequately treated condition. If a breast-feeding infant experiences an adverse effect related to a maternally administered drug, health care providers are encouraged to report the adverse effect to the FDA.
