  1. HA titres were determined in serum and BAL fluid at day of sacrifice (14 or 16 dpc) using 4 HAI units of A/Sw/Eng/1353/09 virus. Results shown are the mean of all individuals in each of the groups ± standard deviation. Serum from pigs immunized with commercial A(H1N1)pdm09 vaccine Pandemrix (GSK) and challenged with A/England/195/09 (pdmH1N1) virus as previously described [11] was used as a positive control and gave a titer of 2048.
