Vaccines are an important tool in fighting porcine reproductive and respiratory syndrome, but the fast-mutating virus that causes the disease sometimes requires the production of autogenous vaccines tailored to particular variants.
The production of autogenous vaccines depends on the ability of scientists to isolate the virus, but sometimes thatâs a tricky process.
A new study from an Iowa State University researcher shows that a new cell line may offer a better alternative to the cell line most commonly used to isolate the PRRS virus. That could lead to more reliable processes for creating autogenous vaccines, but most autogenous vaccine producers would have to make dramatic changes to their processes in order to adopt the new cell line, said Jianqiang Zhang, associate professor of veterinary diagnostic and production animal medicine and lead author of the study.
