There have been many gains in global vaccination milestones, but key challenges threaten progress to date, according to the World Health Organization's (WHO's) Strategic Advisory Group of Experts (SAGE) on Immunization report of 2017 data.
Key findings of the 2018 Global Vaccine Action Plan Assessment Report include:
- Over 116 million children were vaccinated against major diseases.
- Three additional countries reported maternal and neonatal tetanus elimination including Haiti, making the Americas the third WHO region to achieve elimination.
- WHO Eastern Mediterranean Region maintained coverage for basic vaccines at more than 80 per cent, despite eight countries being affected by humanitarian crises.
- Government expenditure on immunisation in the WHO African Region increased by 130 per cent from 2010 to 2017.
- WHO Western Pacific Region recorded its lowest ever incidence of measles, and its first verified rubella elimination for two countries.
- Measles elimination is greatly under threat, with many outbreaks last year, and is now once again endemic in all WHO regions.
- Since 2014, the number of countries reporting vaccine hesitancy has steadily increased, reaching 83 per cent in 2017.
The report comes at a crucial time when the global immunisation community looks towards shaping a new post-2020 vaccination strategy.
