With respect v12 most of the vaccines that have been developed by Pfizer, moderna, AZ and J&J work exactly that way.
Actually, Pfizer and Moderna are mRna type vaccines, which type turns out to be pretty effective, though quite difficult to handle (hefty frozen storage). I would not be surprised, when there is no -70 degrees Celsius storage available in Cambodia, so this rules out Pfizer and somewhat Moderna. mRNA is simply too unstable to use in Cambodia (and Pfizer is also roughly 5 times more expensive than AZ).
AZ and J&J (and the Russia&China vaccines) are vector vaccines and this type seems to be somewhat less effective, with the disputed effectiveness for the older ones, though much easier to store and distribute. And the pricing for the same amount of money, you can vaccinate 5 times more people with AZ than with Pfizer.

I just don’t understand the point of using a vaccine to inoculate those who suffer minimal damage from Covid, and ignore those at risk. It’s as usual as a chocolate oven.
I do, several reasons: The storage temperature, hardly any elderly clusters in Cambodia and pricing.
Western countries do have these clusters, pricing is less of an issue and there you see the prio order to be: Vulnerable, carers, semi-vulnerable (obese, sick and 60+) and then more to "all".
And, let us not forget, in Cambodia, there is a significant handling difference between have money and no money, reflecting the prio, with the result you see.
