Covid-19 vaccine not certain, we never had vaccine for a coronavirus: WHO
World Health Organisation chief Tedros Adhanom Ghebreyesus has said it’s not certain that scientists will be able to create an effective vaccine against the novel coronavirus that causes Covid-19. “We never had a vaccine for a coronavirus… Hoping that there will be a vaccine (for Covid-19), the estimate is we may have a vaccine within one year,” he added.
