A few weeks ago I asked readers to find the errors in the following statement concerning an experimental influenza vaccine produced by Protein Sciences which involves synthesis of the viral HA protein in insect cells. They warned that the virus could mutate during the southern hemisphere’s flu season before returning north in a more lethal form …

The antibody response is crucial for preventing many viral infections and may also contribute to resolution of infection. When a vertebrate is infected with a virus, antibodies are produced against many epitopes on multiple virus proteins. A subset of these antibodies can block virus infection by a process that is called neutralization. Antibodies can neutralize viral infectivity …

The immune response to viral infection comprises innate and adaptive defenses. The innate response, which we have discussed previously, functions continuously in a normal host without exposure to any virus. Most viral infections are controlled by the innate immune system. However, if viral replication outpaces innate defenses, the adaptive response must be mobilized. The adaptive …
