Over four billion doses of coronavirus vaccines have been administered in over 190 countries around the world. However, there is a huge difference between the pace of vaccinations in some countries compared to others.

For instance, countries like China have vaccinated about 1,607,210,845, a figure higher than the vaccination figures for an entire continent.

Some countries in Africa may still depend on donations from COVAX and other countries till the end of the year.

COVAX plans to deliver about two billion vaccine doses globally by the end of the year, while leaders of the G7 countries have pledged to supply one billion vaccine doses to poorer countries, either directly or through the Covax scheme.

Nigeria and South Africa recently received nearly 10 million doses of vaccines from America as its contribution to improving vaccination rates in some of the countries with large populations.

Vaccines With Highest Global Reach

The vaccine produced by Pfizer and BioNTech was the first approved by the WHO, followed by several others.

The Oxford-AstraZeneca vaccine is now the most widely used around the globe.

Unlike Pfizer’s jab – which has to be kept at an extremely cold temperature (-70C) – the Oxford vaccine can be stored in a normal fridge, which makes it easier to distribute.
