Flu vaccine advice
A swine influenza expert has advised that it is a good idea for those working with pigs to have the flu vaccine.
It will obviously protect producers and their workforce but can also reduce the chance of reverse-zoonosis, where humans can infect pigs with human influenza. If pigs become infected with human influenza there is a potential risk for virus reassortment and generating novel viruses.
The flu virus H3N2 has not been detected in GB pigs since 1997, so pigs are essentially immunologically naïve to this strain, whereas H3N2 circulates in the UK human population.
