Is it possible during this time of Covid? My wife swears that she read something about it on a Swiss Information Website somewhere...that grandparents could gain entry into Switzerland (while still quarantining upon arrival) to visit a new grandchild. If somebody has some real information about this could you please let me know? Thanks!
Embassy websites or the US Department of State are the only reliable information sources.

And here is the Swiss government’s information page (in English) for those who are thinking about traveling there:

I'll just add that even accurate information can change quickly. So, the grandparents could plan their travel under one set of rules, only to find a different set applies when they actually are travelling.
