Production of new flu vaccine each year shows it should be possible to adapt to coronavirus variants if necessary.
The technology exists to rapidly tweak vaccines in the face of new coronavirus mutations. But it would take time, and a global strategy is needed to ensure that scientists stay (...)
As countries across the world begin to purchase and roll out COVID-19 vaccines, a key question is how far the vaccine is from reaching Africa and how accessible it will be for the continent. Moina Spooner, Commissioning Editor with The Conversation Africa, asked Mosoka Fallah, an expert on (...)
The race is on to secure vaccines that will protect people from COVID-19. But it’s already become apparent that there is gross inequality playing out in the procurement and distribution of the new drugs. One reason is intellectual property rights. The World Trade Organisation (WTO) is (...)
Covid-19 provides a frightening glimpse of an uncertain future, writes Alan Thornett.
It is not just out of control, but on a global rampage. There have now been 52 million cases and 1,300,000 deaths world-wide. Another million deaths have gone unrecorded, and another million have died because (...)
As we move into the last quarter of 2020, the virus that has defined this troubled year is showing no signs of going away. In the absence of a vaccine or a broadly effective treatment, some are now saying that we must learn to live with COVID-19. But what does that actually look like?
It’s a (...)
There is a global effort to distribute vaccines to poorer countries, but some of the world’s largest countries, including the U.S., Russia and China, do not intend to support the effort.
That lack of backing could have devastating consequences for accessing a COVID-19 vaccine in the U.S. and (...)
• Modelling by Chinese data scientists finds the basic reproduction number around 8 for earliest outbreak in China and in recent months in America
• Team suggests transmission in hospitals is different from those in the community
A new coronavirus carrier in town could pass the virus to (...)
As the world approaches 1 million deaths from COVID-19, we must confront the fact that we are taking a far too narrow approach to managing this outbreak of a new coronavirus.
We have viewed the cause of this crisis as an infectious disease. All of our interventions have focused on cutting (...)
In his article, “C’est la lutte finale“, Mike Davis argues: “The current pandemic on a global scale exposes and widens the existential divides within and between societies, and reminds us that the survival of the poorest fifth of humanity is increasingly at question.” It’s an important piece in (...)
• US study finds the more comfortable alternatives give less protection than cloth and surgical coverings
• Chinese doctor agrees, and describes exhalation valves as ‘selfish’ because they only protect the wearer
Face shields and masks with exhalation valves have become a popular (...)
• Chinese and US researchers have come up with an estimate of 4.54 per cent using new data and modelling based on the initial outbreak in Wuhan
• That compares to estimates ranging from 1.61 to 1.98 per cent for the influenza virus over a century ago
The death rate from Covid-19 could be (...)
Rigid safe distancing rules are an oversimplification based on outdated science and experiences of past viruses, argue Nicholas R Jones and colleagues

Athena Akrami’s neuroscience lab reopened last month without her. Life for the 38-year-old is a pale shadow of what it was before 17 March, the day she first experienced symptoms of the novel coronavirus. At University College London (UCL), Akrami’s students probe how the brain organizes memories (...)

When someone coughs, talks or even breathes, they send tiny respiratory droplets into the surrounding air. The smallest of these droplets can float for hours, and there is strong evidence that they can carry live coronavirus if the person is infected.
Until this week, however, the risk from (...)
Exclusive: King’s College London team found steep drops in patients’ antibody levels three months after infection.
People who have recovered from Covid-19 may lose their immunity to the disease within months, according to research suggesting the virus could reinfect people year after year, like (...)
(CNN)Refusing to wear a face mask during the Covid-19 pandemic should be as socially unacceptable as drunk-driving, or driving without using a seat belt, the president of the UK’s Royal Society said Tuesday.
Venki Ramakrishnan called for everyone to wear a face covering in public — particularly (...)
Open letter says there is emerging evidence of potential for aerosol transmission.
The potential for Covid-19 to spread through airborne transmission by lingering in the air is being underplayed by the World Health Organization, a group of scientists have said.
In an open letter due to be (...)
The world eagerly awaits new vaccines and drugs to combat COVID-19. To deal with a global pandemic, the production of new treatments needs to be scaled up towards supplying the whole world – and as quickly as possible. Borderless open and collaborative science and the free exchange of knowledge (...)
