Vaccine perceptions in a free urban clinic for underserved, uninsured adults

Adult vaccine rates remain low despite public health efforts. Despite the likelihood that underserved patients face more barriers to vaccination, little is known on the perceptions underserved patients have about vaccines as a whole. Additional information could guide health care providers in efforts to improve adult vaccination rates in the medically underserved population.

The primary objective of this survey was to assess perceived susceptibility to and severity of vaccine-preventable disease (VPD) and perceived safety and effectiveness of vaccines in a medically underserved population.

This cross-sectional, descriptive study evaluated vaccine perceptions using a self-administered paper survey in a free clinic providing care to uninsured, low-income adults. All patients with scheduled appointments in the clinic were eligible to participate. Two Likert-type items were used to define responses regarding trust and beliefs. Level of trust was defined as "Not at all" (1), "A little" (2), "Not sure" (3), "Some" (4), and "A lot" (5). Responses to vaccine belief items were defined as "Strongly disagree" (1), "Disagree" (2), "Neither agree nor disagree" (3), "Agree" (4), and "Strongly agree" (5). Statistical analyses were descriptive in nature.

Final analysis included 131 surveys. Health care providers were the most common patient-reported vaccine information source (73.3%) and the most trusted (median: 5). Despite clear agreement among respondents that vaccines are safe (median: 3.94) and effective (median: 4) in adults, with similar results regarding children, the results regarding personal risk from VPDs were less definitive (median: 3).

Overall, survey responses in this uninsured, low-income population indicate that vaccines are perceived as safe and effective, but there is less consensus regarding the individual risk patients face from VPD. Focusing patient education on individual risk as much as overall vaccine safety and efficacy may help improve low adult vaccination rates in the medically underserved.
