Purpose of the Study:
- To describe the data and process leading to New York's adoption of a two-dose measles immunization policy.
- To address the ineffectiveness of single-dose measles vaccination during outbreaks.
- To reduce confusion surrounding measles vaccination recommendations.
Main Methods:
- Analysis of measles outbreak data in New York State during 1989.
- Review of existing measles immunization schedules and recommendations.

Main Results:
- Widespread measles outbreaks occurred in 1989 among students vaccinated with a single dose.
- Outbreaks impacted 21 campuses, resulting in 91 cases and significant vaccination costs.
- Disruptions to scholastic events and public confusion highlighted the need for policy change.
Conclusions:
- New York State adopted a two-dose measles vaccine policy for kindergarten and college entry starting in fall 1990.
- The new policy aimed to enhance measles control and prevent future outbreaks.
- The decision was based on outbreak data, cost-effectiveness, and public health concerns.
