LIMITING THE IMPACT OF INFLUENZA
Grant number: 1071916 | Funding period: 2015 - 2019
The development of better ways to prevent and treat influenza infection will be a major step forward in lessening the impact of the virus in communities worldwide. We have assembled a research team of seven groups who will determine the ways in which the effects of influenza can be mitigated through an understanding of the factors which lead to severe disease, and how these can be lessened by novel vaccination and treatment strategies.
