Answer to the above Question: The parasite’s complex biology played a role in the delay, but experts say there was also a lack of urgency and funding.
My interest in Malaria started when I was growing up in the Philippines. My Father was a victim of this disease and his symptoms of chills and fever, I will always remember during the Japanese-American War in the Philippines (1941-1945). THUS WHEN I joined FDA in 1990, I made sure I will have expert knowledge of drugs that will prevent/treat malaria. As a result in 1993, I was granted my Expertise GS-14 specializing in Anti-Malaria and Anti-parasitic drug products as shown in the Press Release below( 2nd paragraph). My interest with drugs for the treatment/prevention of malaria has never stopped even 20 years after my retirement.

A malaria vaccine is a vaccine that is used to prevent malaria. The only approved vaccine, as of 2021, is RTS,S, known by the brand name Mosquirix. In October 2021, the WHO for the first time recommended the large-scale use of a malaria vaccine for children living in areas with moderate-to-high malaria transmission. Four injections are required for full protection.
Research continues with other malaria vaccines. The most effective malaria vaccine is 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 (Wikipedia).
