As per its website: ETIAS is "a system designed by the European Union to increase security within the Schengen zone by checking the background of travelers prior to a trip to Europe." Nothing about a vaccine mandate.
You said: "in May 2025, WHO and EU impose vaccine mandates on travelers." The vaccine mandate part of this is not true. as respects the EU. I can find no reference to this ETIAS site. Also, there are no requirements for vaccine mandates from the WHO at this point.
