Some places remained more relaxed with their rules than others, i don't think the "open" word is correct to use here.
You mentioned Sweden, now Sweden is not open contrary to the popular belief. This is a plan to phase out restrictions on their government website:
https://www.government.se/articles/2021/05/government-plan-for-phasing-out-restrictions/. What to phase out, if they're open and there are no restrictions?
They have a buttload of regulations, what is expected for their citizens to follow:

Or at least that's not how "to be open" is explained in my dictionary.
They're using drugs against the virus now in many places, which work to an extent, but only if administered at an early stage of the illness. What's the one common thing in those drugs? They're administered after the fact, when the patient is already sick. They are not good for prevention. It's a whole different approach to tackle the issue. They're pretty aggressive too, it's better, if you don't have to take those at all.
Vaccines and these drugs can coexist, which they already do, because there will be a good amount of people, who will never be vaccinated, so they will need the drugs, because contrary to the belief of some of them, they won't be protected by the vaccinated, especially in places, where the vaccination level will stay low.
