You are the MO in charge in a PHC and there has been a plague epidemic in your area. Which of the following measure is the LEAST appropriate for controlling epidemic?
Rapid treatment of cases with streptomycin
Vaccination of all susceptible individuals
Isolation of contacts
Early diagnosis and notification
After vaccination it takes about 5-7 days for the immunity to develop. So it should be carried out at least a week before the expected outbreak. This vaccination is only used for prevention and not control of outbreak. Also know: Tetracycline is the drug of choice for chemoprophylaxis against plague. Ref: Park, Edition 21, Page - 271.
