Summer camp for the tech and media elite kicks off next week, and it will come with strict COVID-19 precautions, Vanity Fair's Joe Pompeo reports.

Officially known as the Allen & Co. Sun Valley conference, the annual retreat in Idaho lures the biggest names in tech, media, and finance, and, while the event was canceled in 2020 due to the pandemic, it's set to kick off next week.

But the conference's A-list attendees will have to follow stringent vaccination and testing guidelines, according to Vanity Fair.

Allen & Co., the private investment firm that runs the event, tapped public health experts from the Mayo Clinic handle safety precautions. Attendees will be required to hand over a photo of their vaccination card or supply immunization records to the Mayo Clinic, and anyone who received a vaccine other than Pfizer, Moderna, or Johnson & Johnson could face extra restrictions.

Guests will also be required to show proof of a negative PCR test within 72 hours of their arrival in Idaho, then take a rapid test once they show up at the event.

In addition, attendees may only bring spouses, no children, and most of the conference events will take place outside, Vanity Fair reports.
