The Evolutionary Consequences of Blood-Stage Vaccination on the Rodent Malaria Plasmodium chabaudi
'Vaccination can drive the evolution of pathogens. Most obviously, molecules targeted by vaccine-induced immunity can change. Such evolution makes vaccines less effective. A different possibility is that more virulent pathogens are favored in vaccinated hosts. In that case, vaccination would create pathogens that cause more harm to unvaccinated individuals.'
I find these findings quite troublesome. And according to this article from last year: Anti-malaria campaign cuts deaths by 38% and apparently they did not use any vaccines.
“The only true wisdom is in knowing you know nothing.”
This is sad. I hope they keep working on it untill it is effective. Malaria is bad illness. It would be lovely to cut down mortality without having to ruing natural habitats with a pesticides.
Yes, sanitation and nets are good but there is limit of their effectivness and you can't always cover everyone.
