The study suggests that climate change can hinder vaccinations through financial instability, food insecurity and erosion of public health infrastructure.

People with prior mental ill health hit harder by pandemic disruption

A new study co-led by UCL researchers found that people with higher pre-pandemic levels of depression or anxiety were more severely affected by job and healthcare disruptions during the pandemic. Those with severe symptoms experienced a much greater likelihood of disruptions to jobs, income, and healthcare.

How a committed minority can change society

An agent-based study found that a committed minority can influence the majority to overturn long-standing practices.
