Our Current Research

The Maldonado Group received a grant from the Bill & Melinda Gates Foundation for a 2.5 year study investigating the dynamics of oral poliovirus vaccine (OPV) household and community transmission in 3 communities in Orizaba, Veracruz, Mexico. Mexico provides a unique environment to study OPV transmission. Currently, Mexican children receive inactivated poliovirus vaccine (IPV) in their primary vaccination series. In addition, children ≤5 years old who have received at least 2 doses of IPV are eligible to receive OPV during biannual National Immunization Weeks. Our study will specifically assess the impact of different OPV vaccination rates during the February 2015 National Immunization Week on intra- and inter-household transmission of OPV. The outcome of this project will inform public policy decision-making regarding OPV cessation and the polio end-game.

Kenya Gender Based Violence Prevention

What Works to Prevent Violence Against Women and Children Programme, UKAID

Sexual assault is a major cause of injury, unplanned pregnancy, HIV infection, and mental health issues worldwide. In parts of sub-Saharan Africa, sexual assault has reached epidemic proportions. Our team is involved in studies evaluating interventions to reduce GBV in Kenya. These include: (1) researching the efficacy of an empowerment and self-defense intervention for adolescent girls in to decrease the incidence of sexual assault and harassment in Nairobi’s large informal settlements and (2) evaluating a micro-finance intervention aimed at improving economic conditions and decreasing GBV among survivors of intimate partner violence.

The group received a grant from the Medical Research Council of South Africa to conduct a cluster-randomized trial of this intervention among young adolescent girls.

Preventing violence against girls

As many as a million people live without basic services such as water, sanitation, and electricity in the informal settlements, or slums, in and around Nairobi, Kenya. The areas are also home to high rates of violence, especially against women. The Maldonado lab is working with PI, Dr. Michael Baiocchi, to evaluate interventions to empower girls and boys to prevent such violence.
