Taking to Twitter, Yvonne asked why scientists were quick to develop a vaccine for Covid-19 while HIV and malaria have been around for many years.

She said: “Vaccine, vaccine. We still don’t have one for malaria nonr for HIV but in few months we have one for Covid, can someone tell me how possible is this? @WHO @EU_Partnerships @UN @NEPAD_Agency @PresidencyZA @Davos @unwomenafrica.”

This tweet annoyed so many as they dragged her for her opinion on the vaccine while others agreed with her.
