Program priorities
In the countries where they work, STOP consultants:
- Advance progress towards polio eradication where polio is present
- Maintain polio eradication where polio is no longer present

- Support disease outbreak prevention, detection, and response
STOP consultants help countries address vaccine-preventable diseases like polio, measles, rubella, and yellow fever. They also help countries respond to emerging threats like Ebola and COVID-19.
