There is no guarantee of a successful vaccine for Covid-19, and the world must live with the threat 'for the foreseeable future', a disease expert has reportedly said.
David Nabarro, professor of global health at Imperial College London and an envoy for the World Health Organisation on Covid-19, told The Observer newspaper that people around the globe will have to adapt to the ongoing threat of coronavirus.
“You don’t necessarily develop a vaccine that is safe and effective against every virus. Some viruses are very, very difficult when it comes to vaccine development,” Dr Nabarro told the paper.
“So for the foreseeable future, we are going to have to find ways to go about our lives with this virus as a constant threat.

“That means isolating those who show signs of the disease and also their contacts. Older people will have to be protected. In addition, hospital capacity for dealing with cases will have to be ensured. That is going to be the new normal for us all.”
His comments come as researchers around the world desperately work on developing a vaccine.
The Sunday Times has reported scientists are investigating using llamas in the quest, with a new Belgian study showing antibodies obtained from llama blood can help neutralise the coronavirus responsible for Covid-19.
With lab rats and mice having also been used in coronavirus research, South Korean scientists say ferrets could have a role to play in testing vaccines too because when infected with Covid-19 they responded similarly to humans, the Times said.

Meanwhile, former health secretary Jeremy Hunt says the pandemic has shown the need for countries to work together in a new global health system involving better co-operation between governments.
Mr Hunt told The Observer global health security would now be “on that small but critical list” of issues, such as climate change, that can only be solved through international working.

Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
