Just over a year ago, the world looked on in shock as the Chinese city of Wuhan imposed the first coronavirus lockdown. Since then, people around the world have made extraordinary sacrifices and have shown great solidarity in containing the spread of the virus.

Yet, when it comes to rolling out vaccines, the world's political leaders seem to have forgotten that we are all in it together.

The European Union has in recent weeks been engaged in a dispute with vaccine makers after AstraZeneca admitted it was expecting a major shortfall in production, and has been accused of prioritizing deliveries to the UK. In response, European officials have introduced temporary export restrictions on vaccines produced in its territories, giving member states the option of limiting exports outside the EU to countries like the UK, the United States and even South Africa.
