Karachi is facing a heightened risk of poliovirus transmission following the detection of the virus in five environmental samples. Health authorities have announced an urgent booster dose campaign aimed at children up to 10 years old. This crucial vaccination drive is scheduled to take place from May 12th to May 25th, covering 89 union committees across the city.
The campaign was announced at a consultation where health experts and international organizations like WHO and UNICEF stressed the importance of unified support. The booster dose is considered a vital intervention to fortify children's immunity and halt poliovirus spread. Preparations include extensive training for frontline workers and mobilization of community leaders, religious scholars, teachers, and media to ensure the campaign's success.
This intensified response is particularly concerning as virus circulation persists during a typically low transmission season. Global efforts have significantly reduced polio cases, but vigilance remains essential in high-risk areas. The vaccine, procured from Indonesia, will be administered safely using jet injectors, with assurances that it is safe, halal, and pain-free, crucial for sustained protection against the virus.
