Anti-H1N1 IgA in lung washes 14 days after two intranasal immunisations with 1 μg of H1N1 mixed with 100 μg of mannan. Mice were immunised twice 14 days apart with 1 μg of H1N1 alone or mixed with 100 μg mannan, and 14 days after the last immunisation lung washes were harvested and assayed for anti-H1N1 IgA.
