Recently, a new technology for stimulating the immune system of piglets has been introduced in the United States. Aptimmune Biologics has introduced their autogenous vaccines using a new adjuvant, nano-partical technology for antigen presentation, and perhas most importantly a new route of administration for PRRS vaccines. The new product works via a two dose intra-nasal administered dose. Scientists at Aptimmune and research institutes where the company has been actively consulting industry experts believe the outcome is a novel vaccine with great potential. MSRC clients began testing the product in November and we hope to report back on advancements that this may represent in the coming 3-6 months as grops are passing through nursery and finishing.
