Concern, but not alarm. Not yet. That's how Dr. Gregory Poland, the head of the Mayo Clinic's Vaccine Research Group, sums up his reaction to the discovery of the H7N9 influenza in China. "If we were to see cases outside of China or in the US, or evidence of human-to-human transmission, then I think it would be justified for us to be very concerned," Dr. Poland told KARE. Poland was among the experts who appeared at a conference on vaccines and preventable diseases Friday at the Minnesota Landscape Arboretum in Chaska.
