"Virus may find it easier to infect people, even if they have had the vaccine"
"Ireland is on alert for a new flu strain that is being blamed for kick-starting an ­early winter surge in cases throughout the UK."
"The H3N2 strain of flu mutated during the summer, which could mean the virus is better able to avoid some of the protections people have from previous infections and vaccines."
A mutated H3N2 influenza strain emerged during the summer and is linked to an early winter surge in cases across the UK. Ireland has been placed on alert because the new strain is thought to have contributed to the rise in infections. The mutation could enable the virus to evade some immune protections gained from earlier infections and from vaccination. As a result, the altered H3N2 may find it easier to infect people, including some who have been vaccinated or previously infected.
