travellers are stuck at Johannesburg’s OR Tambo International Airport

STRANDED… travellers are stuck at Johannesburg’s OR Tambo International Airport, as they are required to have verifiable vaccination certificates with a QR code. 

The South African government recently informed several airlines that it will no longer accept the CDC Covid-19 vaccination "white card" as proof of vaccination. Initially, this requirement only affected road travellers because until recently, travellers could fly to South Africa with the paper booklets. But the new regulation now affects air travellers too.
