Singapore. We are the most highly vaccinated country in the world with around 97% of the eligible population double vaccinated. Boosters have been well underway for some time and yes a big drive to get them now with Omicron. However it's contextual. Since vaccines were approved we have mandatory vaccine passports (double vaxxed + 2 weeks) required to enter pretty much everywhere if you are over 12 years old, shops, shopping centres, cafes, restaurants, outdoor attractions, cinemas, etc. This will soon be the case for boosters.
Since the beginning we have had mandatory masks everywhere over the age of 6 indoors and outdoors off your property, in schools, parks, the middle of the jungle, wherever.... Those who are exempt can wear a shield but honestly I can't remember the last time I saw one. Masks will be here for another year or so at least. It's usually 35 degrees and 70+% humidity. Not many people complain.
We still have a 10.30pm restaurant curfew. Music was banned for a few months but is back now.
We had one brief period of groups of 8 allowed for a couple of months, otherwise we have been in groups of 2 or 5 since the beginning (including family - so when it was groups of 2 could not leave house with the kids), however for the most part schools have remained open as have shops. We are currently at 5. Mask-off activities (ie F&B establishments) have been on and off, but more on than off. Penalties for disobeying the rules are severe (losing work visa, being chucked out of the country etc).
Borders only opened a few months ago and we have limited countries we can go to (around 12 I think) without hotel quarantine on the way home. Hotel quarantine here is significantly stricter than the UK version. Permission from the government is required to travel back into Singapore for the most part. Until recently any covid cases, even asymptomatic, were taken into isolation facilities to "recover". This has now changed to home quarantine (except for Omicron - see below).
The policy here is to open up borders and the country overall but very slowly so minimising deaths - they've very clearly stated they will not follow the UK "freedom day" approach. Their view is that they are one of a few countries who were zero covid to begin with and now want to open - but this means they don't have a similar example to follow and are having to find their own path. There have been less than 800 deaths in total. It's very frustrating but weirdly I also understand it.They need to open - it's too much of a hub not to.
In response to Omicron borders have remained open which is amazing. However now we need to test every day for 7 days on the way back in, one PCR at airport, also at day 3 and 7 in a centre, the others at home. Any Omicron cases detected on arrival are immediately quarantined in hospital. Any close contacts of Omicron cases (ie the entire plane) are taken to hotel quarantine for 7-10 days. To my knowledge 3-4 planeloads have been quarantined so far, I don't know how sustainable this will be in a month, however only fully vaccinated/PCR tested people can enter so I guess imports will be limited a bit. I am travelling back to the UK next week and was nervous they would shut while I was out and we wouldn't get back, but I think they will hold their nerve.
As someone who follows the UK news very carefully and works in immunology/healthcare, I think the British government appears in a panic because nothing seems well thought through and they jump from one extreme to the other with endless accompanying drama. Empty promises, no clear roadmap. Just seems messy. Even though things are WAY stricter here, it also feels calmer and I'm more reassured things will remain stable...
