Malaria Vaccines in Development
Malaria vaccine development is aimed at preventing malaria infection by helping the body develop immunity against the malaria parasite.
Scientists who are developing new malaria vaccines have several challenges to overcome, such as:
Finding a vaccine is vital to decreasing the illness and death caused by malaria infection. More study is needed before people can rely on vaccines to protect them from malaria infection. Until a more effective vaccine is available, avoiding mosquito bites and using medicines are the only ways to prevent malaria infection. (For more information, see the Prevention and Medications sections of the topic Malaria.)
Blood-stage vaccines prevent or contain the malaria infection by limiting the growth of the malaria parasite in the bloodstream. Some vaccines are showing promise in clinical trials.1, 2, 3 But no blood-stage vaccine that can prevent malaria is available to the public yet.
Vaccines that prevent the spread of malaria
Vaccines are being tested that prevent the spread of malaria.4 The vaccine works by preventing the malaria parasites from developing inside a mosquito. So a mosquito that bites a person infected with malaria cannot pass the infection on to another person. The vaccine does not prevent or treat malaria in a person already infected.
