Immunizations – What's New Wendy Jensen Bender, PharmD, RPh SDSU College of Pharmacy and Allied Health Professions RH Rapid City Hospital
Disclosure • I have had no financial relationship over the past 12 months with any commercial sponsor with a vested interest in this presentation.
Objectives • Identify recent updates to the immunization schedule • Define the term "vaccine hesitancy" and list strategies to improve vaccine rates among this patient target group • Summarize recent updates to the immunization schedule • Define the "vaccine hesitancy" and assist the pharmacist in working to improve vaccine rates among this patient target group
Immunization Schedules • Updates and information for persons 0-18y • Influenza • HPV • Tdap • Meningococcal serotype B • Hepatitis A • Pregnancy
Influenza Immunization • Any licensed vaccine can be used for pediatric vaccination • No LAIV with: immunocompromise (or contact with), asplenia (anatomic or functional), pregnancy, antivirals in the last 48h, 2-4y with asthma diagnosis or wheezing within the last 12mo, salicylate medications, allergy to vaccine or components • Precaution with LAIV: asthma if 5yo or older, underlying medical conditions
HPV Immunization • Age 9-14y • 2 doses at 0 and 6-12mo • Series must start prior to 15th birthday • Immune response at least as good as persons 16-26y • Age 15y and older • 3 doses at 0, 1-2mo, and 6mo • Side effects: • Injection site pain, swelling, erythema • Fever, nausea, headache • Syncope more common in "older" females (11-18y) -- recommendation to monitor for 15min after vaccine administration
Tdap Immunization • Update: persons who receive a dose of Tdap inadvertently at age 7-10y or as part of the catch-up series should still receive the routine dose of Tdap at age 11-12y • Immunization schedule recommendation for persons age 13-18y has been clarified • Adolescents with no documented DTaP series should receive a 3 dose primary series • Tdap, Td at least 4 weeks after Tdap, Td at least 6 mo after first Td (second dose in series) • Td booster every 10y • Adverse reactions: injection site pain, redness, swelling
Group B Meningococcal Immunization • ACIP review reasoning for vaccine recommendations • Timing • Disease occurrence • Trumenba (MenB-FHbp) • Bexsero (MenB-4C) • In brief: The benefit of a MenB booster outweighs any risk and may be given 1 year after the primary series if indicated. Currently, there is no information regarding repeat booster doses.
Hepatitis A Immunization • Homelessness an indication • Indicated for 6-11mos if traveling • Travelers over 1y who are unvaccinated • Expected: • Catch-up recommended for everyone 2-18y without documented immunization • Inclusion for children more than 12mo old with HIV infection
Immunization Schedule, Pregnancy • Tdap • No minimum interval • Recommended at 27-36 weeks gestation • Influenza • https://www.cdc.gov/flu/highrisk/pregnant.htm • Mom to be at increased risk • Antibodies pass to the infant • Vaccinate in any trimester
Vaccine Hesitancy Defined The SAGE Working Group on Vaccine Hesitancy: "Vaccine hesitancy refers to delay in acceptance or refusal of vaccination despite availability of vaccination services. Vaccine hesitancy is complex and context specific, varying across time, place and vaccines. It is influenced by factors such as complacency, convenience and confidence." Vaccine, 2015
The "3 Cs" Model Confidence is trust Complacency occurs when the perceived risk of a vaccine is greater than the perceived risk of the VPD Convenience involves affordability, availability, health literacy Vaccine, 2015

Accept some, delay some, refuse some Accept but unsure Refuse but unsure Refuse all Accept all Vaccine, 2015
Vaccine Hesitancy • Review of reasons / types of objections • Safety • Too many vaccines, pain with injections, severe adverse reactions • Necessity • Disease is "natural", VPD are gone/rare/not that severe • Distrust • Vaccines aren't well tested, research inadequate • Societal "norm" • Other children unvaccinated • Religious / personal choice • Right to choose, parent knows what is best, disallowed by religion
Vaccine Hesitancy Tips • Acknowledge concerns • Remain nonjudgmental • Be knowledgeable • Provide science / evidence-based information • Discuss risk / benefit • Remind / educate: • Vaccines are extensively studied prior to licensure • Vaccine safety monitoring does not end at licensure

Vaccine Hesitancy Tips • Acknowledge concerns • Remain nonjudgmental • Be knowledgeable • Provide science / evidence-based information • Discuss risk / benefit • Remind / inform: • Vaccines are extensively studied prior to licensure • Vaccine safety monitoring does not end at licensure
Vaccine Hesitancy with HPV • AAP recommends emphasis on cancer prevention • Better immune response at a younger age • Fewer side effects seen at a younger age • Coadministration with other vaccines can boost response • Use of a "presumptive delivery strategy" • Boost vaccine acceptance • Emphasize safety of the vaccine • AAP has "HPV Talking Points" to help address safety
Adolescent Vaccination • Lack of routine preventative care visits • Adolescent developmental changes • Risk perception • Questioning • Independence seeking • Hesitancy versus lack of knowledge • Advocate for vaccine schedule
