Malawi to Test Groundbreaking Malaria Vaccine

African Nation, Malawi will be undertaking large scale pilot tests for the world’s most advanced experimental malaria vaccine in a bid to prevent the disease that kills hundreds of thousands across Africa and Asia every year.

Vaccine for Malaria

  • Vaccine for Malaria under the trade name Mosquirix has been developed by British pharmaceutical giant GlaxoSmithKline in partnership with the PATH Malaria Vaccine Initiative.
  • Four successive doses of the vaccines must be administered on a strict timetable for it to work.
  • Even though the potential vaccine does not give full protection against the mosquito-borne disease, it is the furthest along in development and so far the most effective.
  • The pilot tests aim to immunize around 120,000 children aged 2 and below to assess the effectiveness of the pilot vaccine and whether the delivery process is feasible.

Malaria which spreads to people through the bites of infected female Anopheles mosquitoes has killed 435,000 people in 2017 alone and the majority of them were children under 5 in Africa.

Genome Sequencing to Map Population Diversity

The Council of Scientific and Industrial Research (CSIR) has undertaken an indigenous genetic mapping effort to educate a generation of students on the “usefulness” of genomics.

About the Project

  • Under the Project, nearly 1,000 rural youth from the length and breadth of India will have their genomes sequenced by the CSIR.
  • The project is an adjunct to a much larger government-led programme which is still in the works to sequence at least 10,000 Indian genomes.
  • Those recruited as part of genome-sample collections are representative of the country’s population diversity and the bulk of them will be college students, both men and women, and pursuing degrees in the life sciences or biology.
  • Genomes will be sequenced based on a blood sample.
  • Every participant would be given a report and would be informed whether they carry gene variants that make them less responsive to certain classes of medicines.

Genome Sequencing

Genome refers to an organism’s complete set of DNA, including all of its genes. Each genome contains all of the information required to build and maintain that organism. Genome sequencing refers to figuring out the order of the DNA nucleotides, or bases, in a genome.
