World Immunisation Week aims to promote the use of vaccines to protect people of all ages against vaccine-preventable diseases across the globe.
This year’s theme is, ‘For every generation, vaccines work,’ and this awareness week will promote how vaccines have safely protected people, families, and communities for generations – and continue to safeguard our future.
