There was a massive push for vaccine development, through large subsidies for research and development to drug companies, pre-orders of vaccines, and other support by the US, Russia, China, and European countries.
This led to the rapid development of multiple Covid-19 vaccine candidates and even more rapid regulatory approval to several of them. Typically, vaccines take several years to be developed and approved, partly because of extended clinical trials to check for all possible responses. But some Covid-19 vaccine candidates were given official approval in Russia and China even before the essential Phase III trials were completed. Even in the US and Europe, regulatory processes were accelerated, sweeping aside the usual demands for complete data and without checking for possible side effects.
Despite such proactive policy, the production and distribution of Covid-19 vaccines has exposed and intensified global inequality. Three features stand...
