Cold Chain Questioned in South Sudan

Akon Mathiong is mourning 2 young grandsons, who died of measles last week in South Sudan.
Both had been vaccinated—spurring concerns of compromised vaccines.
A Kuajok doctor reports more than 10 cases among vaccinated children since January, amid an outbreak that has infected at least 750 nationwide so far this year. The measles vaccine is highly effective, but the cold chain can be challenging to maintain in countries like South Sudan, recovering from years of conflict and prone to power outages.
UNICEF—which provides most of the country’s vaccines, freezers and generators—and the WHO are investigating the questions.
