Nigerian Scientist In ABU ‘Develops
Malaria Vaccine’
A vaccine to prevent high rate of death from malaria fever
was recently developed at the Ahmadu Bello University (ABU), Zaria. Professor Nasiru
Shua’ibu of the Biochemical Parasitology Department of the university who made
the development told the News Agency of Nigeria (NAN) in Zaria, Kaduna State on
Tuesday, that the new malaria vaccine was different from others currently in
use

Mr. Shu’aibu, who is currently working with the Institute of
Tropical Medicine, Japan, said the result of the research on the new vaccine
would soon be out for Nigerians to use.
“In a simple term that a layman can understand, the content
of this malaria vaccine research is difficult, but let me try if I could
simplify it, it is called DNA Vaccine.
“It is a new
technology for discovery and delivery of vaccine against any infectious disease
that was developed in the early to mid 1990s.
“The DNA of the malaria parasite was extracted and the
portion of the DNA that is tested to be a good vaccine candidate is subjected
to molecular biology methods which are used to produce a lot of the DNA,” Mr.
Shu’aibu said.
According to him, the amount of DNA from the malaria
parasite was very minute in quantity and to expand the quantity, Polymerase
Chain Reaction (PCR) was used.
“Then a method of cloning is now used to insert the DNA into
a vehicle that will carry the DNA into either animal or human body.
“It is then injected into the body of the animal or human
and it eventually enters the cells of the animal in the same way a virus enters
and infects cells.
“The injected DNA now uses the cells in the body to produce
chemicals that will prevent malaria from infecting the body,” Mr. Shu’aibu
said.
He said the vaccine was different from any of the licensed
vaccines like polio and other EPI vaccines.
Mr. Shu’aibu added that the approach was also different from
the other malaria vaccine (RTS,S/AS01) that was likely to be licensed but the
goals were the same, to control and eventually eliminate malaria.
Nigeria, with an estimated population of over 170 million,
constitutes the highest malaria burden in Africa and in the world.
Mr. Shu’aibu doubted the figures from the National Malaria
Control Programme (NMCP) indicating progress in containing the disease.
“I still doubt; the tools currently used to fight malaria
are not sufficient to have a substantial and sustained impact that is needed to
resolve the malaria crisis in Nigeria,” he said.
Mr. Shu’aibu said the need to monitor the growing resistance
to anti-malarial drugs and insecticides.
He said if not checked and documented, it would jeopardise
years of global public health success and investments in malaria control.
