With the assistance of colleagues, a vaccinator working from a mobile unit in the Nava Naroda neighbourhood of Ahmedabad, administers the measles vaccine as part of SIA (Supplementary Immunisation Activity)...A vaccination team administered the measles vaccinations to the children of migrant workers from Gujarat's Dahod district currently employed in state capital Ahmedabad.

Their migrant status also makes them particularly susceptible to missing public-health activities including the administering of vaccines. ..This mobile unit successfully vaccinated 77 children on 14 sites across the Nava Naroda neighbourhood of Ahmedabad. Two vaccination teams worked in the van, each consisting of one vaccinator and three link workers together with a supervisor to oversee the activity of both teams.
