Well, there is no stopping for most of the travelers that want to leave Singapore, however many other countries might not even allow tourists in, and at the same even if it’s allowed, it makes no sense to be quarantined for up to 14-21 days and spend a maximum of only 14 days at the destination.
With the ever-changing situation of many countries, the rules or travel bubbles may cease to exist anytime.

There are currently discussions between Singapore & Malaysia on traveling on the reason of compassionate grounds but nothing is cast in stone yet.

Traveling to Vietnam
Foreigners are not allowed in Vietnam will not grant entry visas to foreigners unless you belong to the following category:
- Diplomatic official passports
- investors
- business managers
- experts and high-skilled workers
Do note that even if you fall into any of the categories it is based on a case-by-case basis. Even if you are allowed to go in you will need to be quarantined for 21 days (previously 14), and only allowed to stay for up to 14 days.
Meaning if your allowed entry you must be prepared to stay in Vietnam for over 3 weeks or even 1.5 months.
