Measles resurgence is largely linked to declining vaccination rates, which reduce herd immunity and allow outbreaks to occur.

Key Evidence
The WHO sets a 95% target for routine childhood vaccinations to ensure herd immunity. Uptake in England has been falling for more than a decade, leading to increased vulnerability to measles outbreaks.

What the Evidence Shows
Measles is a highly contagious viral disease that can be effectively prevented through vaccination. The World Health Organization (WHO) recommends a 95% vaccination coverage to maintain herd immunity and prevent outbreaks.
However, in recent years, many regions including England have experienced a decline in routine childhood vaccination rates, falling below this critical threshold. This decline compromises herd immunity, increasing the risk of measles outbreaks and the disease's resurgence. Factors contributing to lower vaccination rates include vaccine hesitancy, misinformation, access issues, and disruptions caused by the COVID-19 pandemic.
Consequently, the statement that measles is coming back because of lower vaccinations aligns with current epidemiological evidence and public health data.
