World Immunisation Week runs from 24–30 April 2026. Led by the World Health Organization and marked across the UK, this year’s theme is “For every generation, vaccines work” — a reminder that immunisation isn’t something we leave behind in childhood. It protects us at every stage of life.
It’s easy to think of vaccines as a children’s health topic. In reality, adolescents, working-age adults and older people all benefit from staying up to date with their immunisations. In the UK, this includes the annual flu vaccine, the shingles vaccine, and COVID-19 boosters for those who are eligible.
Why vaccination matters across every life stage
Our immune systems change as we get older, and so does our risk from certain illnesses. Vaccination needs typically include:
- Infancy and childhood: routine vaccinations that build early protection against serious diseases
- Adolescence: boosters and additional vaccines as protection from earlier doses begins to wane
- Adulthood: workplace and travel vaccinations, alongside catch-up doses
- Older age: flu, shingles and pneumococcal vaccines, which become increasingly important as the immune system weakens
For people living with long-term health conditions or complex care needs, vaccination can be particularly important, as illnesses such as flu or pneumonia can have a much greater impact on someone whose health is already more vulnerable.
Vaccines that matter most for people with complex health needs
- Flu vaccine — recommended annually for those with long-term conditions, reduced mobility, or weakened immune systems
- Shingles vaccine — for eligible older adults, reducing the risk of a painful and sometimes serious illness
- Pneumococcal vaccine — protects against pneumonia and other serious infections, especially important for those with respiratory or neurological conditions
- COVID-19 boosters — for those who remain eligible under current NHS guidance
The barriers that can get in the way
For many people receiving care at home, getting vaccinated isn’t always straightforward. Reduced mobility, difficulty travelling to appointments, communication needs, or anxiety around needles can all make the process feel more daunting than it should be.
Families and carers often play a key role in helping someone understand what a vaccination involves, arrange transport or home visits, and feel reassured throughout.
How we can help
At Synergy Complex Care, our teams work closely with individuals, families and healthcare professionals to make sure vaccination and other preventative health needs aren’t overlooked simply because someone has more complex care requirements.
Our carers can support clients in attending appointments, liaising with GP surgeries and community health teams, and communicating in a way that’s tailored to the individual — helping take away some of the worry that can come with healthcare appointments.
This World Immunisation Week, we’re reminded that protecting health is a lifelong commitment, not a one-off task. If you would like to find out more about how we support individuals with their everyday and ongoing health needs, our team is here to help.
