Humoral and cellular response in humans after immunization with influenza vaccine.

The peripheral blood lymphocyte response and hemagglutination inhibition antibody titers were measured in nine adults before and after immunization with a killed split influenza virus vaccine. Cord blood lymphocytes were tested with the influenza antigen to exclude a nonspecific mitogenic effect. All of the subjects demonstrated preexisting antibody titers and antigen recognition by lymphocytes prior to immunization. The in vitro lymphocyte response after vaccination parallels the humoral antibody response to influenza antigen.

Effect of isoprinosine against influenza and some other viruses causing respiratory diseases.

The antiviral activity of isoprinosine was tested in tissue cultures and mice. In tissue cultures, concentrations of 25 to 100 mug/ml inhibited the infectivity of influenza and herpes hominis viruses but not parainfluenza virus, rhinovirus, or adenovirus. Among different strains of influenza A, there was considerable variability in the inhibitory concentration of isoprinosine. For influenza B, a zone effect was observed in the inhibitory drug concentration. Oral prophylactic administration of isoprinosine beginning 24 hr before infection with an intermediate challenge dose of influenza A and continued as treatment for 5 days produced a significant reduction in mortality. No protection was provided against a high dose challenge. Oral or intraperitoneal treatment of mice beginning 24 hr after infection with influenza A or B viruses significantly delayed or prevented death when the drug was administered for 10 days, but not when treatment was limited to 4 days. An increased fatality rate which occurred in treated mice given a virus dose of low lethality could not be attributed to drug toxicity.
