The World Health Organisation has issued a sobering warning, saying there may never be a coronavirus vaccine that works properly.
The World Health Organisation (WHO) has warned researchers may never manage to develop a coronavirus vaccine that works – and even if they do it could provide only limited protection.
The race is on around the world to create a vaccine, and WHO says promising steps are being made.
However, director-general Tedros Adhanom Ghebreyesus said overnight there might never be a “silver bullet” for COVID-19.
“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,” Dr Tedros told a virtual news briefing in Geneva. “However, there’s no silver bullet at the moment – and there might never be.”
He said the international hunt for a vaccine was historic, but even if one is discovered its success may be limited.
Belgium has the highest per capita death rate with 849 per million of the population.

Since the beginning of June, when much of the country emerged from one of the world’s longest stay-at-home orders, confirmed infections in the archipelago have increased fivefold, surging past 100,000.
Meanwhile, in Europe at least 41 passengers and crew on a Norwegian cruise ship have tested positive for COVID-19.
Ships carrying more than 100 people – including crew – will be barred from stopping off or disembarking passengers in Norwegian ports for at least two weeks.
