Vaccination coverage

The percentage of a population vaccinated at a specific age within a specific population. These maps are used to visualise how widespread vaccination coverage is.

Strategic or operational?

Basemap, baseline or situational?

Baseline and Situational

When might it be produced?

Vaccination coverage is the best indicator of a populations protection against a specific disease. Vaccination coverage maps should be created as soon as the information is available, updated through an emergency as well as historically. It is important to look at these maps over time, including historically to demonstrate baseline coverage as well any increases or decreases in coverage, that could pose a risk to populations.

Intended audience

Invariably health is linked to many other vulnerabilities and is impacted by all eleven clusters in the UN system (sectors of the humanitarian system that help to coordinate a humanitarian response), in particular:

• Nutrition

• Water, Sanitation and Hygiene (WASH)

• Logistics - transport / access

The intended audience includes a variety of actors either directly involved in health, or those supporting health needs:

• Ministry of Health / Department for Health

• National Health Care Providers

• Local Government

• Civil Society / Community Organisations

• Affected communities / population

• National and International health related NGOs

• National Red Cross / International Federation of Red Cross

• World Health Organisation

• Emergency Medical Teams /Emergency Medical Teams Coordination Cell

Influence on humanitarian decisions

Will be dependent on if the maps are strategic, operational or both and will vary by intended audience. To be updated based on planned expert interviews.

Methods

Access to timely and accurate data is essential for a health response. It is important to get the best available data although it may not always be perfect. Questions should be asked such as:

When was the data collected? What time period does it cover? When will it next be updated? How accurate is the data? Are the figures actual or estimates? What age range do this data cover?

Robust information management and governance is essential when accessing, storing and visualising health data. The agreed use of the data must be established and recorded from the outset.

A process of data manipulation may be required to ensure individuals, families or villages can not be identified. A number of methods can be used to achieve this including the suppression of small numbers, aggregation of data to a higher level and minimising the use of other data / detail on a map that could make identification easier. These checks must be in place to ensure patient’s right to privacy and dignity are maintained.
