Fig 8. Antibody responses in mice.

A: vaccinated at 3 week intervals with 1790GAHB containing 29 ng or 1859 ng protein. B: at day 21 following a single injection of 1790GAHB containing 29, 116, 465 or 1859 ng protein. This is the result from a potency study; half the mice were vaccinated with the appropriate doses of a formulation of 1790GAHB prepared from the reference batch of 1790-GMMA stored at -80°C (blue, +) and formulated 2 days before vaccination. The other mice were vaccinated with appropriate doses of the NVGH 1790GAHB vaccine stability batch (red, X). All doses contained the same amount of Alhydrogel in 0.5 mL buffered saline.
