"Background: Immunization plays a very important role in decreasing under-five mortality. Universal Immunization Program performed quite well in the first decade of its introduction. However, surveys carried out during NFHS and UNICEF revealed that there has been a decline in the coverage levels of different vaccines by as much as 15-40%. Objectives: To monitor routine immunization and growth monitoring services and to provide necessary feedback to district and state authorities and suggest corrective actions. Material and Methods: A cross sectional observational study was conducted in Sinor block of Vadodara district, Gujarat. Two PHCs out of three PHCs of this block were selected and all thirteen sub centers of these PHCs were selected for monitoring of VHND. One village of each sub center was selected and monitored during Mamta Day for various components of vaccination and growth monitoring. Results: All thirteen Mamta day sessions were held according to micro plan. Presence of all team members was seen at all centres. However, supervisory visits were observed in only 23% of the sites. Necessary logistics and vaccines were available at all sites. Cold chain status was satisfactory. 23% of female health workers (FHW) faced problem in technique of giving BCG and Measles immunization. Time of reconstitution was written on BCG and Measles vials at 61.5% sites. Although Anganwadi workers (AWW) weighed children correctly, plotting was not satisfactory in 38 % of children. Conclusion: Although all observed sessions were held as per microplan, supervision was lacking in majority of the sessions. Vaccine, logistics and cold chain maintenance was satisfactory. Few of the FHWs faced problems in immunization technique and so did some AWWs in Growth plotting. "
