Supporters will not be able to attend football matches in the Netherlands until there is a coronavirus vaccine, Dutch health minister Hugo de Jonge says.
Sport in the country is currently at a standstill due to the virus, and the Dutch government have banned all sporting events until September 1 at the earliest.
That decision resulted in the Eredivise being ended prematurely, with no champions and no relegation.
De Jonge wrote to the Dutch parliament to explain that, even if the government chooses to allow sporting events to resume from September, fans will not be present.
He wrote: "We cannot yet mention a date for the last step, the mass gatherings. That is actually only possible if there is a vaccine and no one knows how long it will take. We hope of course soon, but a year or more is very real."
Medical experts say developing a new vaccine takes, on average, 10 years.
However, due to the heavy international interest and investment in developing a coronavirus vaccine, some experts believe one could be ready in a matter of months.
Around the world, approximately 460 trials are taking place with the aim of combatting coronavirus.
