There may never be a 'silver bullet' for COVID-19, WHO warns
The World Health Organization warned on Monday that there might never be a “silver bullet” for COVID-19 in the form of a perfect vaccine and that the road to normality would be long, with some countries requiring a reset of strategy, Reuters reported.
More than 18.14 million people around the world are reported to have been infected with the disease and 688,080 have died, according to a Reuters tally, with some nations that thought they were over the worst experiencing a resurgence.
WHO Director-General Tedros Adhanom Ghebreyesus and WHO emergencies head Mike Ryan exhorted nations to rigorously enforce health measures such as mask-wearing, social distancing, hand-washing and testing.
“The message to people and governments is clear: ‘Do it all’,” Tedros told a virtual news briefing from the U.N. body’s headquarters in Geneva. He said face masks should become a symbol of solidarity round the world.
“A number of vaccines are now in phase three clinical trials and we all hope to have a number of effective vaccines that can help prevent people from infection. However, there’s no silver bullet at the moment - and there might never be.”
The WHO head said that, while the coronavirus was the biggest health emergency since the early 20th century, the international scramble for a vaccine was also “unprecedented”.
But he underscored uncertainties. “There are concerns that we may not have a vaccine that may work, or its protection could be for just a few months, not more. But until we finish the clinical trials, we will not know.”
