NCT01873040

Brief Summary

This study will assess the effectiveness of social media website devoted to vaccines to change immunization knowledge, perceptions and behavior. If effective, this intervention will represent an innovative, low cost and broadly applicable resource to reduce parental vaccination concerns. The study has two hypothesis:

  1. 1.Parents receiving usual care plus social media website will demonstrate higher early childhood immunization rates to parents receiving either usual plus non interactive website or usual care only.
  2. 2.Parents receiving usual care plus social media website will demonstrate positive changes in knowledge, attitudes and beliefs supporting vaccination compared to parents receiving either usual care plus non-interactive website or usual care only.

Outcome Measures

Primary Outcomes (1)

  • Days under-immunized

    Days under-immunized is a metric to identify immunization delay. For each vaccine dose calculate the difference between when the vaccine dose was actually administered and when the vaccine dose should have been administered according to the Advisory Committee on Immunization Practices (ACIP) schedule. That difference is summed across all doses and vaccines for a total number of days under-immunized for each child. Total days under immunized was calculated 200 days after life or after enrollment. If someone had 0 days at that time they were considered "up to date".
