The UPS Foundation, which leads the global citizenship programs for UPS, and Gavi, the Vaccine Alliance, have announced support for the expansion of a medical drone network into Ghana.

Zipline, a California-based automated logistics company, will use drones to make on-demand, emergency deliveries of 148 high priority products including emergency and routine vaccines, blood products and life-saving medications.

The service will operate 24 hours a day, seven days a week, from four distribution centres – each equipped with 30 drones – and deliver to over 2,000 health facilities serving 12 million people across the country.

The high level of genetic diversity between individual tumors suggests that if it were to be developed, a broad cancer vaccine would be unlikely to work for more than 0.3 per cent of the population, according to new research published in the open access journal Genome Medicine.

Next generation sequencing has revealed a wealth of information on the genetic diversity of tumors, which in turn has led to research into individualised treatments for cancer based on the molecular characteristics of a patient’s tumor.

Cancer vaccines are one type of prospective treatment that involves turning the patient’s immune system against the tumor.

Dr Ryan Hartmaier, lead author from Foundation Medicine, USA, said: “A broad or semi-universal vaccine capable of targeting many different tumors would be seen by some as the ‘holy grail’ of cancer therapy as it wouldn’t involve the time or cost of individualising treatment.
