Better preparation, listening to the science and acting together in solidarity, are some of the main ways that countries across the world can overcome the on-going COVID-19 crisis, the UN chief told the World Health Summit on Sunday.

With countries and pharmaceutical companies around the world gearing up to distribute COVID-19 vaccines following trials, the UN Children’s Fund UNICEF has begun laying the groundwork for the rapid, safe and efficient delivery by buying and pre-positioning syringes and other necessary equipment.

Amid a potential global shortage in influenza vaccines and the ongoing COVID-19 pandemic, the UN health agency has advised countries to protect the elderly and health workers first.

Global leaders, including more than 30 Heads of State and Ministers, have underlined their commitment towards fast-tracking the development and production of COVID-19 tests, medicines and vaccines, that will be available for anyone, anywhere, who needs them.
