ABUJA, Nigeria – The World Health Organization highlights major gains in global immunisation while warning of rising challenges threatening future progress.
WHO immunisation director, Kate O’Brien, on Thursday says vaccines have saved over 150 million lives but gaps persist.
“Extraordinary progress has been made, but significant challenges remain,” she states.
Experts at a global advisory meeting flag declining funding, conflicts, and weak health systems as key risks to vaccine delivery.
The WHO stresses the need for stronger surveillance, equitable access, and public trust to sustain immunisation success. WHO Warns of Immunisation Challenges Despite Global Progress Gains
