COVID-19 has affected 220 countries and regions in the world, according to WorldOMeters. It is continuing to grow as the virus spreads and mutates, and while there is promising evidence to suggest the vaccine is saving lives, there are various issues with relying solely on the vaccine to keep us safe. For example, not everyone has had their 1st or 2nd doses in the UK, and on a global scale, poorer, LICs are not getting the same volumes of vaccines as HICs.
