Can teachers demand students to get vaccinated?

Body: 

From this week on, UU's lecture halls will all be full of students once again. Many students and teachers welcome this with a sigh of relief, but others worry we might be doing too much, too soon. How safe is it, really? A teacher in Twente recently wrote an op-ed saying he would prefer to only allow vaccinated students in his classroom. Others want to require students to at least get tested before class. Are they taking things too far? DUB polled UU students on the street to see how they feel about it.
