Saha et al., 2018, Bangladesh | Inhabitants of the city of Mipur (n =268,896), divided by clusters and 3 study arms. G1 vaccination (n = 95,115); G2 vaccination and behavior change (n = 93.09); G3 No intervention (n = 80,690). | Cholera | ERDAS IMAGINE software-geographic-monitoring-system | Once the areas to be vaccinated were mapped using ERDAS, the socioeconomic profile of the population was determined. Vaccination campaigns were conducted based on the global positioning data. After vaccination, hospital surveillance of new cases was conducted to observe the effect of the methods used in mass immunization | At GI (G1+ G2 =188,206), n = 123,686 individuals were vaccinated with two doses of the vaccine. The fulldose was administered in 66%. Women were more involved, and 80% of the sample consisted of the vaccinated population (aOR: 1.80; 95% CI = 1.75-1.84) and younger people, under 15 years of age (aOR: 2, 19; 95% CI =2.13-3.26) | The instrument provides health managers with an understanding of the impact of the participation of different vaccine providers in immunization campaigns |
Wilson et al., 2012, Canadá | Children aged 2, 4, 6, 12 and 18 months. N = No informations | Diphtheria, pertussis, tetanus, poliomyelitis, [Hib] (DaPT-IPV-Hib), measles, mumps, MMR and meningococcal C | VISION Data Systems (vaccine and immunization surveillance in Ontario) | They studied the safety of vaccines given to children in Ontario at 2, 4, and 6 months of age and then at 12 and 18 months of age | Reduction in events (mortality or morbidity rate) after mass vaccination. The event rate in the 3 days before vaccination was about half that of the event rate in the control period for the 4- and 6-month vaccinations | The strategy may help measure the impact of vaccination programs, but further studies are needed |
