The Mumbai civic body on Thursday issued detailed instructions to its nodal officers for giving 'precaution' or booster dose of COVID-19 vaccines to healthcare professionals, frontline workers and senior citizens above 60 and with comorbidities from January 10 and said their inoculation will be free at government and corporation-run centres.

In an internal circular, the Brihanmumbai Municipal Corporation (BMC) stated that health workers, frontline staffers and people above 60 with comorbidities will be eligible for 'precaution' dose if they have completed nine months, or 39 weeks, from the second dose of their COVID-19 vaccine.
