New vaccine aims to keep parasitic infection at bay in kids

This study tested a vaccine called Bilhvax, given alongside a standard treatment (praziquantel), to see if it could delay the return of schistosomiasis (a parasitic infection) in children aged 6 to 9 in Senegal. The vaccine was given as three shots plus a booster one year later. The main goal was to see if vaccinated children had fewer or later recurrences of the infection over three years compared to those who received a placebo. The study also monitored safety.
