‘No silver bullet’

Coronavirus cases were first reported in China in December last year. In March, the World Health Organization declared it a pandemic.

The number of officially confirmed coronavirus cases has shot past 18 million with more than 690,000 deaths, according to the Johns Hopkins University. So far, 1,468,689 people recovered.

On Monday, WHO chief Tedros Adhanom Ghebreyesus warned that there is no ‘silver bullet’ for a vaccine against Covid-19. “There might never be,” he told a regular press briefing in Geneva.

He said a number of vaccines are now in phase 3 clinical trials, and we all hope to have a number of effective vaccines that can help prevent people from infection.

“The message to people and governments is clear: do it all,” he said, “and when it’s under control, keep going!”
