Ground Report

An artificial virus protected mice against polio and the approach might be used to make a range of safer new vaccines against viruses according to US researchers. The team has created the first artificial virus,a synthetic version of polio in 2002. They used it to vaccinate mice and then infected the mice with what should have been a deadly dose of polio. The mice survived. These viruses are still far from suitable vaccines for humans but there is a lot of potential for this approach.
