"Malaria is known as one of mankind’s top killers. Challenging conventional ideas, scientists in Europe conducted a daring experiment. They used mosquitoes as flying needles to deliver a vaccine of live malaria parasites through their bites.
They were astounded by the results. People in the vaccine group acquired immunity to malaria. The experiment was done in a lab at Radboud University in the Netherlands.
I don't get it. Please help me understand this.
Thanks a lot!
