Duration of Neutralizing Antibody Titer after Japanese Encephalitis Vaccination

Estimation of focus reduction neutralization test for measurement of neutralizing antibody titer against Japanese encephalitis virus.

Short duration of neutralizing antibody titers after pre-exposure rabies vaccination with suckling mouse brain vaccine.

The human anti-rabies pre-exposure treatment currently used in Brazil, employing a 1-ml dose of suckling mouse brain vaccine (SMBV) administered on days 0, 2, 4 and 28, was compared to an alternative treatment with two 1 ml-doses on day 0, and one 1 ml-dose injected on days 7 and 21. The latter induced higher virus-neutralizing antibody (VNA) titers on day 21. Both Brazilian rabies vaccines pro...

Anti-influenza antibody Level after Vaccination

Abstract: Introduction: Influenza is highly transmitted disease and vaccination is the most effective way to prevent influenza. This research was designed to study the variation of serum antibody level among the subjects had already been vaccinated against influenza. Materials and Methods: This research is a descriptive-analytical study, which was carried out on 196 subjects who had influenza v...

Neutralizing and Complement-fixing Antibody Production and Resistance following Vaccination in Experimental Encephalitis Infections

In mice vaccinated subcutaneously with different doses of virulent W.E.E. virus or with formolized vaccine, neutralizing and complement-fixing antibodies paralleled resistance to some extent yet appeared in groups in which resistance remained undetectable, persisted at a similar maximum level in spite of different titers of resistance, and after resistance had become negligible. In mice vaccina...
