The president of the philippines Rodrigo Duterte has agreed to serve as guinea pig and to inoculate a new vaccine to protect Russian against the coronavirus, announced Wednesday his spokesman.

This announcement comes a day after the announcement by Russian president Vladimir Putin of the development by his country of the "first" vaccine against the Covid-19 ensuring a " lasting immunity ". However, many western scientists have expressed their scepticism about the speed with which the vaccine would have been developed.
