Bangkok governor Aswin Kwanmuang announced the plan on Friday, saying this measure is part of the second phase of vaccine rollout now that frontline medics and others at risk have been inoculated.
Vaccinations will be delivered at BMA-run hospitals as well as department stores specified by the Thai Chamber of Commerce.
The governor added that 10 million doses will be delivered between June and December, which works out to 40,000 to 50,000 jabs a day.
To be eligible, people are required to register via the @MorPhrom Line account.
