Authorities in Sierra Leone on Thursday started a nationwide rollout of the single-dose Ebola vaccine, the first such campaign in West Africa where a deadly outbreak 10 years ago resulted in the death of thousands.
The 2014 Ebola outbreak – the deadliest in history – was primarily in West Africa but affected Sierra Leone the most, with nearly 4,000 deaths out of the more than 11,000 recorded globally. The country also lost 7% of its healthcare workforce to the outbreak.
