Michael Gerson writes about the latest malaria vaccine research in the WaPo:
If the vaccine works as promised, it would be an extraordinary scientific milestone: the first highly effective vaccine against a parasite. And this particular parasite has been living in human hosts, and killing them, since humans evolved. Hundreds of thousands of people die of malaria each year, mainly children under 5. A vaccine that prevents infection — rather than treatments that modify the severity of the disease — is important to malaria eradication. Even people with a low level of parasites and no symptoms can transmit the disease, through mosquitoes, to others.
While researchers play scientist — maybe their work will be fruitful, more likely not based on history — hundreds of thousands will die from malaria this year, mostly children under five year of age.
They need insecticide technology now — not pie-in-sky vaccine development.
