Hong Kong plans to require foreign domestic workers to get Covid-19 vaccination.

Each domestic worker works in close proximity to a family, over long periods of time. If the worker catches Covid-19, person is very likely to transmit it to that family. Therefore, the worker should be vaccinated.

Perhaps people who work in stores and deal with the public should also have to be vaccinated. A store worker rarely spends even 5 minutes near one customer, but one infected worker in a store for hours can fill the store with virus and several people could catch Covid-19 from that.

The likelihood of this depends on the store's ventilation system. It also depends on whether customers keep wearing masks when in a store.

The only sort of exception that, for ethical reasons, needs to exist is for those who, for medical reasons, cannot be vaccinated. Hong Kong says it will offer that exception.

Aside from those people, anyone who feels discriminated against by this policy has a simple solution at hand: get vaccinated. It's the right thing to do and the safe thing to do. Humanity needs to eradicate Covid-19, and this is the way. Stop complaining, and get vaccinated!

However, for the time being, many people don't have the option of getting vaccinated, because they live in places where little or no vaccine is available. It would be proper for a country that has money to burn, such as Hong Kong (i.e., China), to offer people admitted with work visas vaccination before or after arrival, if they are coming from one of those places.

Singapore is using a disco ad to encourage people to get vaccinated.
