The new malaria vaccines are likely going to be mRNA based. These have already been rolled out in Africa with millions of the two dose regimen already given. The vaccines are said to be 77% effective. (yeah right!…lol). Anyway here is an article from Reuters on the subject:

“Scientists around the world have been working for decades to develop a vaccine to prevent malaria that infects millions of people every year and kills more than 400,000 – most of them babies and young children in the poorest parts of Africa.

Malaria is a complex infection caused by a parasite that evades recognition by the immune system, said Sahin, adding the goal is to develop a vaccine that makes the parasite visible and attackable from the very beginning.

Messenger RNA vaccines prompt the human body to make a protein that is part of the pathogen, triggering an immune response. They are also quicker to develop than traditional vaccines and can be adapted relatively easily.

“The very high efficacy of two mRNA vaccines for COVID-19 have shown the world just how powerful this technology could be against many diseases, including malaria,” said World Health Organisation (WHO) head Tedros Adhanom Ghebreyesus, who started his career as a malaria researcher”.
