Around 5,000 concert-goers were taking part in the experimental event at Paris’s Bercy concert hall. A further 2,500 volunteers who did not attend the concert would be used as a comparison group.
The trial to assess the risk of Covid transmission at events has been eagerly awaited by the live music and entertainment sector which has been devastated by Covid-19.
“It’s been so long that we have waited for a reopening of this kind of event. So finding a concert, in addition to it being Indochine, is really great,” Camille, 26, from the Paris region, said.
Before being admitted, the concert-goers, all aged between 18 and 45 with no special risk factors, handed over an envelope containing a saliva test done earlier on Saturday.
Each person was also required to have had a negative antigen test in the last three days.
Once inside, no social distancing was required but masks were compulsory.

Due to the 9pm curfew still in place in France, the concert started earlier than normal with Indochine on stage by 6 pm.
Similar trials have already taken place elsewhere in Europe and the Bercy concert had been postponed a number of times.
It was finally being held two days ahead of the opening up of France’s vaccination programme to all adults.
Results from the concert-goers’ study are expected by late June.
The study was organised by the AP-HP (Assistance publique-Hopitaux de Paris), the Paris-based university hospital trust, and Prodiss, the national union for musical and variety shows, with support from the government.
Previous experimental events in Spain and Britain have not shown any increased risk of transmission.
