That’s confusingly worded and not enforced. I can confirm that fully vaccinated people flying from South Africa to the Netherlands did not need negative PCR tests until this week. You’re only required to fill in a declaration of vaccination status on the South African side.

Source: I did the trip in late October, and colleagues just returned in mid-November. None of us had to have negative PCR or any other tests.

On today’s episode of BBC World Service podcast they interviewed a canadian journalist who flew on one of those flights and she said that they as passangers were not asked to get tested before boarding.

She said she only tested herself since her following flight from AMS mandated it.

Ah thanks. That sorts out why the passengers were tested despite dutch regulations.
