New malaria vaccine is fully effective in very small clinical trial according to : Ars Technica

according to Healthy adult volunteers were given three doses of this vaccine at 28-day intervals before being challenged with exposure to the malaria parasite.
That involved another small trial, and the vaccine wasn’t quite as effective as this, protecting only about two-thirds of those who received it.
A recent study published in Nature shows that a new vaccine for malaria is well tolerated by humans and can provide significant immunity to malaria.
The authors of this study are also planning future work that will determine how long vaccine recipients remain immune to malaria.
To make this new vaccine, the parasites were first rendered harmless via radiation and then rapidly frozen for preservation.

as declared in Instead, SEEK created a vaccine composed of four synthetic mosquito saliva proteins.
When it detects it, an immune response ensues that’s different from the one normally incited by a bite.
Instead, researchers will draw the participants’ blood and see if it displays a modified immune response to the mosquitos’ saliva.
We also know that saliva proteins tend to trigger an allergy-like response—that pink, itchy welt after a bite.
Finding the right cocktail of saliva proteins might seem like a sticking point, since we don’t know what most of them do.

New vaccine provides lasting protection against multiple strains of malaria in clinical testing

as declared in It contained weakened Plasmodium falciparum (P. falciparum) sporozoites, which do not cause infection but can trigger an immune response in the body.
“An effective malaria vaccine will need to protect people living in endemic areas against multiple strains of the mosquito-borne disease,” NIAID Director Anthony S. Fauci said.
Through clinical testing at the National Institutes of Health’s Clinical Center, the vaccine was found to be well-tolerated and protective for more than one year against the P. falciparum malaria strain matched to the PfSPZ vaccine.
Results of the Phase 1 clinical trial were published in the journal Proceedings of National Academy of Sciences.
According to a recent study conducted by the National Institute of Allergy and Infectious Diseases (NIAID), an investigational malaria vaccine protected a small number of healthy adults from infection with a malaria strain different from that contained in the vaccine.
