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
