Thousands of people die every day from malaria, a disease that is transmitted to humans solely through mosquitoes. With CRISPR, scientists can easily genetically engineer mosquitoes incapable of transmitting malaria and using a technique called gene drive, they can force that genetic change into the native mosquito population. So, should we do it?
This is good news in the fight against malaria, which kills almost 800,000 people annually (that’s a San Francisco, every single year).
An experimental vaccine from GlaxoSmithKline halved the risk of African children getting malaria in a major clinical trial, making it likely to become the world’s first shot against the deadly disease.
Final-stage trial data released on Tuesday showed it gave protection against clinical and severe malaria in five- to 17-month-olds in Africa, where the mosquito-borne disease kills hundreds of thousands of children a year.
“These data bring us to the cusp of having the world’s first malaria vaccine,” said Andrew Witty, chief executive of the British drugmaker that developed the vaccine along with the nonprofit PATH Malaria Vaccine Initiative (MVI).
While hailing an unprecedented achievement, Witty, malaria scientists and global health experts stressed that the vaccine, known as RTS,S or Mosquirix, was no quick fix for eradicating malaria. The new shot is less effective against the disease than other vaccines are against common infections such as polio and measles.
GlaxoSmithKline has previously stated that they will sell the vaccine for cost + a 5% markup that will be put back into tropical disease research.
