THE WORLD HEALTH ORGANIZATION (WHO) has warned that a vaccine for coronavirus might never be found.
Director-general Tedros Adhanom Ghebreyesus said that a "silver bullet" answer to the pandemic is far from guaranteed, despite scientists around the world pushing to develop one.
Instead, he urged governments and citizens to keep on doing the known basics, such as testing, contact tracing, maintaining physical distance and wearing face coverings.
"We all hope to have a number of effective vaccines that can help prevent people from infection," Ghebreyesus said at a virtual press conference on Monday.
"However, there's no silver bullet at the moment, and there might never be.
"For now, stopping outbreaks comes down to the basics of public health and disease control.
"Do it all," he stressed.
Around the world, Covid-19 has infected over 18 million people, killing just under 700,000.
Experts have suggested that life as we knew it prior to the outbreak won't return until a vaccine for the virus is found and distributed around the world.
Despite the warnings from the ever-positive WHO, many potential coronavirus vaccinations are currently being tested, including one led by an Irish research team at the University of Oxford.
The team suggested last month that the vaccine could be rolled out to the public as early as October, providing it passes all the necessary tests.
