It carries the antigenic determinants of the Duffy blood group system which consist of four codominant alleles—FY*A and FY*B—coding for the Fy-a and Fy-b antigens respectively, FY*X and FY*Fy, five phenotypes (Fy-a, Fy-b, Fy-o, Fy-x and Fy-y) and five antigens. Fy-x is a form of Fy-b where the Fy-b gene is poorly expressed.
[jargon] [52] In widely cited in vitro and in vivo studies, Miller et al. reported that the Duffy blood group is the receptor for P. vivax and that the absence of the Duffy blood group on red cells is the resistance factor to P. vivax in persons of African descent. [5]
The most effective malaria vaccine is the R21/Matrix-M, with a 77% efficacy rate shown in initial trials and significantly higher antibody levels than with the RTS,S vaccine. It is the first vaccine that meets the World Health Organization's (WHO) goal of a malaria vaccine with at least 75% efficacy, [6] [7] and only the second malaria vaccine ...
The Cobas malaria test, made by Roche, can detect RNA and DNA from the parasite that causes malaria in donor blood, organs and tissue. Malaria transmission through a blood transfusion is not ...
RTS,S/AS01 (commercial name Mosquirix) is the only malaria vaccine approved and in current use. The vaccine's use requires at least three doses in infants by age 2, with a fourth dose extending the protection for another 1–2 years. [3] The vaccine reduces hospital admissions from severe malaria by around 30%. [3]
The RTS,S vaccine was endorsed by the World Health Organization in October 2021 for broad use in children, making it the first malaria vaccine to receive this recommendation. [4] As of April 2022 [update] , 1 million children in Ghana, Kenya and Malawi have received at least one shot of the vaccine, with more doses being provided as the vaccine ...
The world's second vaccine against malaria was launched on Monday as Ivory Coast began a routine vaccine programme using shots developed by the University of Oxford and the Serum Institute of India.
Malaria is the deadliest among infectious diseases, accounting for approximately 429,000 human deaths in 2015 as of the latest estimate by the World Health Organization. [2] In humans, malaria can be caused by five Plasmodium parasites, namely P. falciparum, P. vivax, P. malariae, P. ovale and P. knowlesi. [3]
