Vaccine hesitancy is one of the greatest threats to global health – and the pandemic has made it worse
In 2019, the World Health Organization (WHO) identified vaccine hesitancy as one of its top ten threats to global health.
- In 2019, the World Health Organization (WHO) identified vaccine hesitancy as one of its top ten threats to global health.
- It appears this threat has only increased since the COVID pandemic.
A perfect storm for infectious diseases
- In England, for example, childhood vaccination coverage generally plateaued from around 2011 and declined from around 2014.

- For example, the number of countries with significant measles outbreaks rose by 50% between 2020–21 and 2022–23.
- The combination of reduced vaccine coverage, overstretched healthcare systems, and the return to pre-pandemic levels of social contact have created a perfect storm for infectious disease rates to rise.
What drives vaccine hesitancy?
- One of the main factors leading to hesitancy towards COVID vaccines specifically has been concern that the vaccines were developed too quickly.
- However, we know that COVID vaccines are safe and effective.
Misinformation is a vector of disease
- Over the course of the pandemic, we’ve seen widespread misinformation around the safety of COVID vaccines, which has unsurprisingly been linked to reduced confidence in the vaccines.
- The problem with misinformation is how intractible it can be.
How do we increase vaccine confidence?
- For example, a study from Japan predicted that vaccine hesitancy in relation to the HPV vaccine between 2013 and 2019 could lead to approximately 5,000 deaths from cervical cancer.
