• Vaccination plays an important role in pandemic planning and response. The possibility of developing an effective vaccine for a novel pandemic virus is not assured.

• 43.7% of the world population has received at least one dose of a COVID-19 vaccine, 6 billion doses have been administered globally, and 28.48 million are now administered each day. Only 2% of people in low-income countries have received at least one dose.
