Worked Solution & Example Answer:Name a development in the history of our understanding of malaria and identify a prevention strategy that resulted from that development - HSC - SSCE Biology - Question 25 - 2014 - Paper 1
Step 1
Name a development in the history of our understanding of malaria and identify a prevention strategy that resulted from that development.
Answer
A significant development in our understanding of malaria was the discovery that the disease is transmitted by mosquitoes. This led to the implementation of prevention strategies, such as the use of mosquito nets, which protect individuals from mosquito bites when they are most active at night.
Step 2
Outline how a vaccine against malaria would prevent the occurrence and spread of the disease in a population.
Answer
A vaccine against malaria would stimulate the immune system to produce memory B cells and memory T cells. When an individual encounters the malaria-causing Plasmodium, these immune cells would recognize and respond rapidly to destroy the pathogen. If a large portion of the population is vaccinated, the transmission of the malaria parasite would decrease significantly. This herd immunity reduces the likelihood of outbreaks and can potentially lead to the eradication of malaria in the population.
