Scientists fear that no vaccine will be found against the coronavirus. The world could find itself forced to live with “the constant fear of Covid-19,” according to Professor David Nabarro, global health expert.
This Saturday, WHO stirred up global concerns by stating that there was still no evidence of immunity for those who contracted Covid-19. In South Korea and China, cases of people declared cured and then again positive for SARS-CoV-2 have been reported.
More than a hundred vaccine projects are currently under study around the world, in an attempt to immunize populations against the virus.

No vaccine has yet been found for a coronavirus
“The world must remain cautious. We must not believe that we are going to find a vaccine for the disease which will make it possible to be cured for life, as it works for a disease like measles “, alerted Christopher Witty, the medical adviser of the British government, before the parliamentarians this Friday. “Vaccines are sought for all forms of infectious diseases, but we do not find them for all,” he added. No vaccine has yet been found for a form of coronavirus.
In an interview with the magazine The Observer, the doctor and expert in global health, David Nabarro expressed the same reservations: “We do not necessarily find a vaccine, safe and effective for all viruses. Finding a vaccine can be extremely complicated for some viruses. In the near future, it is better that we find ways to live our lives despite the constant fear of the virus. ”
limit mortality
Faced with the complexity of the virus, scientists could opt for vaccines allowing them to be partially protected.
“We can find vaccines insufficient to provide total immunity, but sufficient to prevent contracting a severe form of the disease,” said doctor Christopher Witty.
