Web-based tailored messages do not increase infant vaccination rates

(HealthDay) – According to a study published online October 12 in Pediatrics, delivering web-based vaccine messages tailored to parents’ vaccine beliefs and values ​​does not improve infant vaccination intake.

Jason M. Glanz, Ph.D., of Kaiser Permanente Colorado in Denver and colleagues conducted a randomized clinical trial between April 2016 and June 2019. A total of 824 pregnant women and new parents were randomly assigned to the web-based “Vaccines” and Your Baby “(VAYB) intervention, which provided vaccine information messages based on the beliefs and values ​​of the vaccine, a non-tailored version of the intervention (UT) or new parents the usual care (UC; 276, 274 and 274, respectively) were tailored.

The researchers found current vaccination rates of 91.44, 92.86, and 92.31 percent in the VAYB, UT, and UC arms. The likelihood of being up to date on vaccinations was no higher in infants in the VAYB arm than in the UC arm (odds ratio 0.89; 95 percent confidence interval 0.45 to 1.76) or in the UT arm (Odds Ratio 0.82; 95) percent confidence interval 0.42 to 1.63). There was no difference between the UT and UC weapons in terms of likelihood of being up to date (odds ratio, 1.08; 95 percent confidence interval, 0.54 to 2.18).

‘Given that vaccine hesitation remains a major public health concern, researchers should continue to develop and test communication approaches to reduce parent vaccination concerns and improve the timely intake of vaccinations for infants “write the authors.
