Immunisation: The Key to Public Health

1 August 2024

As Immunisation Awareness Month arrives, it’s a prime opportunity to emphasise the critical role that vaccines play in maintaining public health. Immunisation is one of the most effective ways to prevent disease, protect communities, and save lives.

Understanding Immunisation

Immunisation is the process by which an individual is made resistant to an infectious disease, typically by the administration of a vaccine. Vaccines stimulate the body’s immune system to recognize and fight pathogens, such as viruses or bacteria, without causing the disease itself.

How Vaccines Work

Vaccines contain weakened or inactivated parts of a particular organism (antigen) that triggers an immune response within the body. Newer vaccines contain the blueprint for producing antigens rather than the antigen itself. Regardless of whether the vaccine is made up of the antigen or the blueprint, this weakened version will not cause the disease in the person receiving the vaccine, but it will prompt their immune system to respond as it would have on its first reaction to the actual pathogen.

The Benefits of Immunisation

Disease Prevention
- Immunisation protects against various diseases, including measles, mumps, rubella, polio, and influenza. It helps prevent outbreaks and reduces the incidence of vaccine-preventable diseases.
Herd Immunity
- When a significant portion of a community is immunised against a contagious disease, it provides indirect protection (herd immunity) to those who are not immune. This includes individuals who cannot be vaccinated, such as those with certain medical conditions.
Reduction in Healthcare Costs
- Preventing disease through vaccination is cost-effective. It reduces healthcare spending on treatments, hospitalisations, and long-term care for those who may suffer from complications of vaccine-preventable diseases.
Eradication of Diseases
- Vaccination has led to the eradication or significant reduction of certain diseases. For example, smallpox was eradicated globally through a successful vaccination campaign, and polio is now close to being eradicated.
Protection Across Lifespan
- Immunisation is important at all stages of life. From childhood to adulthood, vaccines protect against different diseases at different ages, ensuring ongoing health and well-being.

Importance of Staying Up-to-Date with Vaccinations

Protecting Vulnerable Populations
- Keeping vaccinations up-to-date ensures that vulnerable populations, such as infants, elderly individuals, and those with weakened immune systems, are protected from potentially life-threatening diseases.
Preventing Resurgence of Diseases
- Even if a disease is rare, maintaining high vaccination rates is essential to prevent its resurgence. Travel and globalisation mean diseases can be reintroduced to areas where they were previously under control.
Adapting to Emerging Threats
- Staying current with vaccinations allows for protection against new and emerging diseases, as well as new strains of existing diseases. For example, annual flu vaccines are updated to combat the most recent virus strains.

Addressing Vaccine Hesitancy

Despite the proven benefits, vaccine hesitancy remains a challenge. Misinformation and myths about vaccines can lead to decreased vaccination rates, posing risks to public health. It’s important to address concerns with credible information, highlighting the safety, efficacy, and importance of vaccines in preventing disease.

Vaccines Available at Private Medical Clinic

Immunisation is a cornerstone of public health, offering protection against many infectious diseases. By staying informed and up-to-date with vaccinations, individuals contribute to the health and safety of their communities. As we observe Immunisation Awareness Month, let’s celebrate the success of vaccines in saving lives and continue to advocate for widespread immunisation to protect future generations.
