Measles morbidity in Australia, 1991–2009

Australian Measles Control Campaign

The Australian Measles Control Campaign (AMCC) was a significant public health initiative undertaken in Australia aimed at reducing the incidence of measles through widespread vaccination. The campaign was launched in response to the high rates of measles infections observed in the country, particularly among children. Measles is a highly contagious viral disease that can lead to serious health complications, including pneumonia, encephalitis, and death. The AMCC represents a critical effort in Australia's public health history to control and eventually eliminate measles.

Background

Before the introduction of the measles vaccine in 1969, measles was a common childhood disease in Australia, causing significant morbidity and mortality. Despite the availability of the vaccine, measles outbreaks continued to occur, highlighting the need for improved vaccination strategies. In the early 1990s, it was recognized that the existing approach to measles vaccination was insufficient to achieve herd immunity, the level of immunization within a population that significantly reduces the risk of disease transmission.

Campaign Objectives

The primary objective of the AMCC was to significantly reduce the incidence of measles among Australian children. Key goals included:

• Increasing the coverage of the first dose of the measles-mumps-rubella (MMR) vaccine among children aged 12 to 15 months.
• Implementing a nationwide catch-up vaccination program for all children aged 5 to 12 years who had not been vaccinated or had only received one dose of the vaccine.
• Enhancing surveillance of measles to better identify outbreaks and monitor the effectiveness of the campaign.

Implementation

The AMCC was implemented in several phases, starting in the late 1990s. The Australian government, in collaboration with state and territory health departments, rolled out a comprehensive plan that included mass vaccination clinics, school-based vaccination programs, and public education campaigns to raise awareness about the importance of measles vaccination.

Healthcare professionals played a crucial role in the campaign, administering vaccines, providing education, and reporting measles cases to public health authorities. The campaign also utilized the Australian Childhood Immunization Register (ACIR) to track vaccination coverage and identify areas with low immunization rates.

Impact

The AMCC was highly successful in increasing measles vaccination coverage across Australia. The catch-up vaccination program significantly reduced the number of susceptible children, leading to a marked decrease in measles cases and outbreaks. By the early 2000s, Australia was on track to eliminate measles, defined as the absence of endemic measles transmission for at least 12 months.

Challenges

Despite its success, the AMCC faced several challenges, including vaccine hesitancy among some parents, logistical issues in reaching remote communities, and the need for ongoing vigilance to prevent imported cases of measles from leading to outbreaks.

Conclusion

The Australian Measles Control Campaign is a testament to the effectiveness of coordinated public health initiatives in controlling vaccine-preventable diseases. Through widespread vaccination and enhanced surveillance, Australia has made significant progress towards the elimination of measles. The AMCC serves as a model for other countries aiming to control or eliminate measles and underscores the importance of vaccination in protecting public health.
