More than one billion doses of COVID-19 vaccines have been administered in China.
Health officials say it took just five days to administer the latest 100 million doses.

If it gets too hot or too cold (some vaccine formulations must be protected from freezing), the active ingredients can degrade and become less effective. Once a dose of vaccine is manufactured, it needs to be transported to immunization programs and clinics and health centers all over the world, and then remain viable until it’s needed.
