Just a heads up:
Dumaguete City has started vaccinating seniors with their second booster last friday.
For now the location is the City Health Office at City hall (next to the Fire Station).
I asked, and they have no intention to move to a different location (I predict that will change; as soon as more than 30-40 people show up to get vaccinated it's going to be chaos there).
Anyway, I was lucky to enquire on Friday and got boostered that same day (Pfizer).
Anyone wanting to take their chance this coming week, do yourself a favour and go early.
