[Complex studies of virology, microbiology, biochemistry and epidemiology in the adults of a semi-closed community vaccinated against influenza with the inactivated NIVGRIP vaccine intranasally].

A study was conducted on the specific and non specific immunomodulator effects of the inactivated vaccine NIVGRIP. The results revealed the seroconversion of HAI antibodies against influenza and mumps viruses and the reduction of viral and microbial flora of the pharynx. The kinetics of some proteins specific to the acute stage (siderophiline antitrypsin, microglobulin, complement C1q and C2 factors, C reactive protein and fibronectin) was also investigated and significant quantitative modifications were noticed in vaccinated subjects.
