However, progress enabled the three-time world champion to travel to Ibiza in December where he unfortunately contracted a flu virus while celebrating Christmas with his family, a state of affairs that was bad news for Lauda's vulnerable immune system.
According to a report the Krone, the former driver was transported earlier this week back to the intensive care unit of Vienna's AKH hospital.
Lauda, who will be 70-years-old on February 22, had tentatively scheduled a return to the paddock for Melbourne, but that target may have to be pushed back following his latest medical setback.
