Figure 1.4. Letter to Pharmacists From the Department of Health and Human Services Requesting
Help in Promoting and Providing Vaccinations
     Thank you all for your tremendous efforts this past year to raise immunization rates in the United States.
     Outbreaks of pertussis (“whooping cough”), influenza, and measles, and continued low vaccination rates
     for human papillomavirus (HPV), Tdap (tetanus, diphtheria, and pertussis), zoster vaccines and others
     are critical reminders of the ongoing efforts that are needed.
     Pharmacists and community vaccinators are uniquely positioned to promote and provide vaccines to
     people in a wide range of communities. In addition, their extensive reach into diverse communities
     allows greater access to vaccines for those who may not have a medical home, and who traditionally
     have had lower rates of vaccine use.
     The Centers for Disease Control and Prevention (CDC) and the Department of Health and Human
     Services (DHHS) ask for your continued support and efforts to help address vaccination needs in your
     communities. We know you are asked to do a lot to help your patients, but as trusted health care
     professionals, research shows that your recommendation to receive needed vaccines is vital.
     As just one example, only about 10 percent of adults living with an infant report having had Tdap
     vaccination.1 But, a 2012 survey conducted by Harris Interactive found that 45% of unvaccinated adults
     who have been in contact with babies under 2 years in the past 5 years or expect to be in contact with
     them in the next 12 months would consider getting Tdap vaccine if a family member asked. However,
     83% would consider getting Tdap vaccine if they were asked by their doctor or other healthcare
     professional.2 These results underscore the importance of your recommendation for protecting your
     patients and their families.
     Specifically, CDC and HHS are asking pharmacists and other vaccine providers to:
        1. Increase awareness among their patients about recommended vaccines, especially for adults and
             adolescents where vaccination rates are lagging.
        2. Ensure that the people who visit your pharmacies or clinics are aware of which vaccinations they
             need by assessing their vaccine needs and offering those vaccines, e.g.:
                 a. Offer Tdap vaccine to replace one dose of Td. This is especially important for anyone
                    who will be around infants given outbreaks of pertussis in the United States.
                 b. Inform pregnant women that they are recommended to receive Tdap vaccine after week
                    20 of pregnancy and influenza vaccine anytime during pregnancy.
                 c. Offer yearly influenza vaccine for everyone 6 months and older.
                 d. Offer zoster vaccine for adults 60 years and older.
                 e. Offer pneumococcal polysaccharide vaccine for everyone 65 years and older.
        3. For patients with certain medical conditions, recommend and offer vaccinations specifically
             recommended based on their high risk conditions, e.g.:

                   a. Remind patients with diabetes that they need influenza vaccine, pneumococcal
                        polysaccharide vaccine, and hepatitis B vaccine.
                   b. Consider targeting immunization messages to patients within your prescription database
                        based on their medications and/or age.
                   c. Incorporate immunization reminders to patients and caregivers during counseling and
                        medication therapy management (MTM) encounters.
             4. Enter adult immunizations into vaccine registries (i.e. immunization information systems) in states
                where this is possible and provide documentation to the patient (consent form and/or
                immunization card) and/or their primary care provider to ensure appropriate recording of
                immunizations.
             5. Partner with state and local health departments, immunization coalitions, medical providers, and
                others in your communities to increase collaboration and outreach to those who need vaccines.
