TVI is ensuring provision of vaccines through health camps, community interventions, and school-based programs.

TVI was the first NGO to introduce school-based typhoid vaccination program.

Community and school-based surveys are reliable methods to collect data which represents general population. TVI has been engaged in conducting these surveys even in the most remote areas which produce data that can be used for policy making and intervention planning.

The corner stone in achieving better health outcomes is creating awareness among the masses. TVI plays its part by establishing health camps in geographical areas where there are extreme barriers, resulting in better awareness and health care utilization.

TVI has delivered various services in underprivileged communities to help increase the health profile of the country.

TVI in collaboration with other research organizations is performing surveillance of enteric pathogens in Karachi and other areas of Pakistan. This will help to identify the disease burden in high risk communities.

Over the past number of years TVI has produced massive data to help create more complex study designs or interventions.
