World Immunisation Week 2026

World Immunisation Week

World Immunisation Week

World Immunisation Week highlights the vital role vaccines play in protecting people of all ages from serious and potentially life-threatening diseases. Immunisation is a safe and effective way to prevent illness and reduce the spread of infections within our communities.
Vaccines help your immune system recognise and fight infections quickly and effectively. In the UK, routine vaccination programmes protect against diseases such as measles, mumps, rubella, flu, and more. These programmes have helped to significantly reduce the impact of many infectious diseases.
However, it is important that everyone continues to take up the vaccines they are offered. This ensures not only personal protection but also helps protect those who are unable to be vaccinated, including babies, older adults, and people with weakened immune systems.

Why vaccination is important

  • Protects you from serious diseases
  • Helps prevent outbreaks in your community
  • Protects vulnerable people who are at greater risk of complications
  • Reduces pressure on NHS services

What you can do

  • Check that you and your family are up to date with routine vaccinations
  • Attend vaccination appointments when invited
  • Speak to your GP, nurse, or pharmacist if you have any questions or concerns

Our commitment
The NHS is committed to providing safe, effective vaccines and ensuring they are accessible to everyone who needs them. By working together, we can continue to protect our communities and save lives.
