Highlights
:: Adult contacts of infants are willing to receive recommended vaccines during prenatal clinic appointments, infant hospital or clinic visits.
:: Males had higher vaccine hesitancy than females. Perceived barriers to vaccination differed between males and females.
:: Expanding existing immunization platforms may increase adult vaccine uptake.
Abstract
Objective
Adult vaccination coverage is low and current strategies are unlikely to achieve Healthy People 2020 targets. We determined the attitude of adult infant contacts toward recommended adult vaccines and their willingness to receive vaccines should they be available during hospital visits or prenatal or infant clinic appointments.
Methods
Survey of predominantly Hispanic, underinsured and medically underserved infant contacts at a county hospital in Houston, Texas where a pertussis cocooning program is offered.
Results
Two hundred and eighty-five contacts (mean age 32.8 years [18–73]; 94.8% Hispanic) participated. Most were fathers (58.2%), followed by aunts (19%), and grandparents (12.3%). Participants used many health information sources. 221 (77.5%) considered healthcare providers the most influential on their decisions but only 51.6% reported healthcare visits within the prior year. Forty-one (14.4%) discussed family vaccinations during prenatal visits. Preferred locations for adult vaccination were hospital or clinic-based (96.5%). Lack of knowledge (22.8%), fear of pain/needles (14.7%), work commitments (14%), lack of transport (11.2%), cost (10.2%) and fear of side effects (5.3%) were barriers to vaccination. More males than females reported fear of pain/needles and work commitments (P 0.01 and P 0.02, respectively), and more females lack of transport (P < 0.001) as barriers. Most planned to (76.1%) or had received (7%) pertussis vaccine; if available, 73.3%, 53.3% and 50.5% expressed willingness to receive vaccines against influenza, pneumonia and meningitis, respectively. Age, ethnicity or education was not associated with willingness to be vaccinated. Vaccine acceptance was higher in females than males for pertussis (P 0.04), influenza (P 0.008), pneumonia (P 0.04), and meningitis (P 0.006) vaccines by multiple regression analysis.
Conclusions
Most adults were willing to be vaccinated if offered during hospital visits or clinic appointments for mother or infant. Development and expansion of recommended immunization platforms, such as the cocooning platform, offers the opportunity to increase adult vaccination coverage.
