Measles vaccinations have become an urgent public health priority in Gauteng as the province grapples with a growing outbreak of the highly contagious disease. With 181 laboratory-confirmed cases recently recorded, health authorities and experts are sounding the alarm, urging communities to act swiftly to prevent further spread.
Hotspot areas include Tshwane, Johannesburg, and Ekurhuleni, where clusters of infections continue to rise. According to health officials, the outbreak underscores the critical need for higher immunization rates—particularly in vulnerable and densely populated areas.
Measles vaccinations remains one of the most contagious diseases in the world. According to the World Health Organization, one infected person can transmit the virus to 9 out of 10 unvaccinated individuals in close contact. The primary method of preventing infection is through the MMR vaccine (measles, mumps, rubella), which is typically administered in two doses during early childhood.
In Gauteng, however, vaccine coverage has fallen well below the required levels. Associate Professor Talitha Croxley, academic division head of the School of Nursing at the University of the Western Cape, has emphasized the urgency of improving measles vaccination rates.
“Vaccination coverage in Gauteng is under 75%, and that’s too low,” Croxley stated. “To prevent a measles outbreak, a community needs at least 95% coverage. That leaves very little room for hesitation.”
What’s Behind Low Measles vaccinations Rates in Gauteng?
Professor Croxley pointed to multiple factors contributing to the low rate of measles vaccinations in the province. One of the biggest disruptions came during the COVID-19 pandemic, when routine immunization services were significantly interrupted.
“Post-COVID, we had many people who could not access vaccinations. Some were afraid to visit clinics due to fears around the virus, while others faced logistical issues,” Croxley explained. “Marginalised communities are particularly affected, and in some cases, parents are hesitant to vaccinate due to misinformation or mistrust.”
Beyond logistical and psychological barriers, there are also issues around healthcare accessibility, education, and outreach—especially in informal settlements where public health messages may not always reach their intended audience.
While Gauteng faces challenges, other provinces like the Western Cape have made notable progress. Recent targeted vaccination campaigns led to 90% coverage in the Western Cape—closer to the ideal threshold that helps communities achieve herd immunity.
These campaigns included mobile clinics, school-based outreach programs, and strong public education efforts aimed at both parents and adults. Croxley emphasized that the success in the Western Cape could serve as a blueprint for Gauteng.
“With the right strategies—especially community-level engagement—we can significantly increase measles vaccination rates,” she said. “It’s not just about availability, but also about accessibility and trust.”
While most public health messaging around measles targets children, Croxley noted that adults should also be proactive in checking their Measles vaccinations status.
“Many adults assume they were vaccinated, but records are often lost or incomplete. It’s advisable, particularly during an outbreak, for adults to consider getting an additional MMR vaccine if they are unsure,” she said.
In some cases, adults may have only received one dose in childhood, especially if they grew up during times when the two-dose schedule wasn’t widely practiced. Incomplete Measles vaccinations can leave individuals vulnerable—especially when traveling or working in high-risk environments like schools or hospitals.
Another reason why measles vaccinations are so essential is the severity of the disease. Though often described as a “childhood illness,” Measles vaccinations can lead to serious complications, including pneumonia, brain inflammation (encephalitis), permanent hearing loss, and even death—particularly in young children and immunocompromised individuals.
Croxley warned against underestimating the virus. “We’ve seen severe outcomes even in previously healthy children. Preventing measles vaccination is far safer and more effective than treating it after infection.”
With 181 confirmed cases and counting, the outbreak in Gauteng is a stark reminder of what can happen when vaccine coverage falls below safe levels. The Department of Health is expected to intensify its outreach and may soon introduce emergency measles vaccination campaigns in hotspot areas.
Health officials are urging:
-
Parents to ensure their children’s vaccines are up to date.
-
Adults to check their own vaccination history.
-
Communities to engage in accurate health education and combat misinformation.
-
Local clinics and schools to support mobile and pop-up vaccination sites.
The path to controlling the outbreak is clear: more measles vaccinations, more outreach, and more cooperation.
In the words of Professor Croxley, “Vaccination is not just an individual choice—it’s a community responsibility. The health of our children and our cities depends on it.”
