Pakistan launched its first national polio vaccination campaign of the year on February 23, aiming to reach more than 43 million children under age 5. The campaign kicked off a few days earlier, on February 21, in six districts of south Khyber Pakhtunkhwa (KP) to ensure extensive focus and monitoring in the high-priority area. During the nationwide effort, 339,521 health workers will go house to house to administer vaccines. On January 27, Pakistan marked a significant milestone of no wild polio cases reported in the past 12 months, although it remains in the environment in certain districts of KP.
