Red Bull motorsport boss Helmut Marko said he advised his drivers to become infected with coronavirus while the season is in hiatus.
The 76-year-old said he had the idea to bring his Formula 1 drivers and juniors together in a camp, which "would be the ideal time for the infection to come".
"They are all strong young men in good health. That way they would be prepared whenever the action starts," he said.
The rest of Red Bull management were against the idea, which was abandoned.
"Let's put it this way: it has not been well received," Marko said.
