Australia's Low Vaccination Rates Spark Measles Outbreak as Holiday Travel Fuels Surge in Infections
The country's early childhood vaccination coverage has dropped to 89.7%, below the critical 95% threshold required for herd immunity, according to data from the National Centre for Immunisation Research and Surveillance (NCIRS). This decline is attributed to a decrease in vaccinations among two-year-olds, with coverage falling by 11.4 percentage points compared to pre-pandemic levels.
The rise in measles infections has been fueled by summer international travel, which has allowed individuals infected abroad to spread the virus across the country. The recent "Boxing Day cluster" β a surge of seven cases linked to a single traveller who was infectious while moving through public areas β prompted health alerts in New South Wales and South Australia.
Health authorities are urging all Australians to verify their vaccination status, particularly those born after 1966 who have not had two doses of the MMR vaccine. Eligible individuals can receive a free booster to protect themselves against the highly contagious disease.
While Prof Peter Collignon, a microbiologist at the Australian National University, notes that there is no immediate threat of a national measles epidemic, he warns that a decline in vaccination rates means the virus can spread more readily than it did 10 years ago. With international travel on the rise and low vaccination rates in some countries, authorities are taking steps to mitigate the risk of infection.
Symptoms of measles typically include fever, cough, runny nose, followed by a distinctive red rash several days later. As the country experiences an uptick in cases, health experts emphasize the importance of maintaining high vaccination rates to protect against this potentially deadly disease.
