I urgently need help concerning polio vaccine at city hall.

Longonot62, please give me any contact at city hall. Am to travel for a meeting with tickets already booked and visa granted. problem of 6 weeks wait will cause me a great  delay.

I know that you can get the Yellow Fever vaccine at City Hall, but wasn't aware that they offer the Polio vaccine.  In any case, we just walked in, paid (cash only) and got the YF vaccination on the spot - you don't make an appointment.  Probably took around 45 minutes in total.
