Looking good that Switzerland (and I'd assume most/all the remaining Schengen countries) will open to vaccinated tourists by 28 Jun. Just to get a definitive decision on this will be great.
_Facilitated entry from third countries
Since 19 June 2020, people from third countries outside the Schengen area are subject to special entry restrictions aimed at curbing the spread of the coronavirus. Since then, these restrictions have been gradually relaxed by the Federal Council. As part of a development of the Schengen acquis, the EU now intends to repeal the entry restrictions still in force in the Schengen area for third-country nationals with a vaccination certificate. As a Schengen associated state, Switzerland has coordinated its travel restrictions with the EU as far as possible since the start of the pandemic.
In turn, Switzerland plans to ease entry restrictions still in force for third-country nationals with a vaccination certificate from 28 June 2021. There are currently no travel restrictions between Schengen states. Furthermore, people benefiting from free movement enjoy this right regardless of the state they come from when they enter Switzerland.
The Federal Council proposes to put the concessions into effect on 28 June 2021. The Federal Council's proposals will be submitted for consultation to the cantons, the social partners and the competent parliamentary committees until 16 June. The Federal Council will decide on 23 June._
