Trials of malaria vaccine bring hope to fight the disease


A malaria vaccine trial from Oxford University showed that it was 77% effective – much better than the current shot to control the world’s most deadly diseases.

Jab, R21, is the first to exceed the World Health Organization’s target for a vaccine available at about 75% by 2030. Mosquitoes, the first malaria vaccine, first introduced in 2015, took GSK more than 30 years to develop and was close to 39 percent employees for more than four years.

In Section 2b – middle – test R21, those in the small group had a 77% chance of contracting malaria after 12 months following those who received rabies as a supplement. Those who received the lowest dose of the vaccine had a 71% chance of contracting the disease. There were no serious side effects.

The study recruited 450 children aged 5 to 17 in Burkina Faso.

Oxford researchers, working with India’s Serum Institute and a vaccine maker in the US Novavax, has already launched a third phase to test the vaccine in more people. Participants were also given an additional photo.

An integrated immunosuppressive vaccine incorporates an antigen that reflects the immune system, with Novavax’s Matrix-M agents to help it perform better. Novavax is also using adjuvant in its Covid-19 vaccine, which a third phase has found to be 89 percent helpful.

Adrian Hill, director of the Oxford’s Jenner Institute, who co-authored the Oxford / AstraZeneca Covid-19 vaccine, co-authored a paper on the R21 trial. He also said the results have helped “high expectations” for the vaccine.

“With the devotion of our fellowman, Serum Institute of India, to make at least 200m doses annually in the coming years, the vaccine could be a serious problem for groups if it is approved, “said Hill.

Malaria kills more than 400,000 people a year, mostly among African children. Another 229m cases of the disease were reported in 2019.

But it has been difficult to find a vaccine against the disease, with more than 100 cases being asked in clinical trials.

Halidou Tinto, director of the Institut de Recherche en Sciences de la Santé in the Burkina Faso department of Nanoro and the main investigator of the trial, said he hoped to show greater power in the third case.

“This is a very interesting result that demonstrates the unprecedented performance of a vaccine that has successfully tolerated our testing program,” he said.
