I mean I can't blame them, it supposedly causes side-effects in 40% of cases, isn't very effective against some mutations, and the population they want to vaccinate doesn't have a huge risk of severe covid to begin with.

Aside from this the politicians really bungled the marketing. First it was claimed it doesn't work in the elderly (which wasn't true, just illiteracy), then they said the younger people will only get this vaccine, not the other ones. It's bound to make people suspicious.

Maybe they should learn from Frederick the Great of Prussia: "Trying a less direct approach to encourage his subjects to begin planting potatoes, Frederick used a bit of reverse psychology: he planted a royal field of potato plants and stationed a heavy guard to protect this field from thieves. Nearby peasants naturally assumed that anything worth guarding was worth stealing, and so snuck into the field and snatched the plants for their home gardens. Of course, this was entirely in line with Frederick's wishes." [1]
