3 Vaccinations

4 Vaccinations: An overview
What is a vaccine? “A product that stimulates a person’s immune system to produce immunity to a specific disease, protecting the person from that disease” Can be comprised of: killed microorganisms live attenuated organisms living fully virulent organisms Centers for Disease Control and Prevention. cdc.gov. (2014)

5 Vaccinations: An overview
How does a vaccine work? Stimulate the production of antibodies to provide immunity against one or several diseases The College of Physicians of Philadelphia. historyofvaccines.org. (2016)

6 Vaccinations: An overview
Why are the benefits? Individual immunity Herd immunity Drastic reduction of disease Small pox Polio Diphtheria Measles The College of Physicians of Philadelphia. historyofvaccines.org. (2016) Centers for Disease Control and Prevention. cdc.org. (2016)

10 Vaccinations: An overview
Immunogenicity in Solid-Organ Transplant Suboptimal response to vaccines Suppressed humoral and cellular responses Degree of immunosuppression Type of transplant Vaccination pre-transplantation is preferred When vaccines are given post-transplant: Can administer vaccines at months post-transplant Typically recommend waiting for 6 months The College of Physicians of Philadelphia. historyofvaccines.org.

(2016) Rubin LG, et al. Clin Infect Dis. (2014) Kumar D. Curr Opin Infect Dis. (2014)

31 Caregivers and Living Donors
Immunizations Caregivers and Living Donors

32 Immunizations: Caregivers and Living Donors
Immunocompetent individuals should receive vaccinations (both live and inactivated) according to the CDC annual schedule Yellow fever vaccine and oral typhoid vaccine should be received prior to travel in relevant areas If skins lesions develop after receipt of varicella or zoster vaccines, avoid direct contact with immunocompromised persons until the lesions clear Living Donors Vaccinations should be up-to-date Avoid live vaccines within 4 weeks of organ donation Vaccination solely for recipient’s benefit is generally not recommended Centers for Disease Control and Prevention. cdc.gov. (2016) Rubin LG, et al. Clin Infect Dis. (2014)

33 Patient Case

34 Patient Case: GM 14 year old female, presents to kidney clinic for transplant evaluation. Immunization record: DTP/aP: 5 of 5 HepA: 2 of 2 Hep B: 3 of 3 Hib: 4 of 4 Polio: 5 of 5 Last flu: 9/20/2015 MMR: 2 of 2 PCV7/13: 4 of 4 PPSV23: 1 of 1 Rubella: 2 of 2 Varicella: 2 of 2

35 Patient Case: GM What vaccinations would you recommend? PPSV-23
PCV-13 and HPV Influenza and HPV Influenza and PPSV-23

36 Patient Case: GM What vaccinations would you recommend? PPSV-23
PCV-13 and HPV Influenza and HPV Influenza and PPSV-23

37 Patient Case: GM Mom tells you her daughter is not sexually active and asks you why she should receive HPV vaccine. What do you say? We encourage our potential transplant recipients to receive all appropriate vaccinations prior to transplant in order to produce a stronger immune response and provide longer lasting immunity. There is a higher burden of HPV-related disease in kidney transplant recipients and evidence that HPV vaccination after a solid-organ transplant produces a diminished response.

38 Patient Case: GM Mom and GM agree to the immunizations you recommended today. GM says the last time she received her flu shot, her arm was red and sore for a few days. She asks you what the chance is that she will have a severe reaction to the flu shot this time. How do you respond? <1 in 1,000,000 chance 1 in 1,000,000 chance 10 in 1,000,000 chance 100 in 1,000,000 chance

39 Patient Case: GM Mom and GM agree to the immunizations you recommended today. GM says the last time she received her flu shot, her arm was red and sore for a few days.

How do you respond? <1 in 1,000,000 chance 1 in 1,000,000 chance 10 in 1,000,000 chance 100 in 1,000,000 chance
