29%) developed protective antibody titer
after receiving their 4th dose of vaccine compared with other trials done by Goyal et al.
In the control group, average maternal antibody levels were as high as 8 of HI antibody titer
at hatch and thereafter decreased quickly.
Post-immunization pneumococcal antibody titers
and IgG subclasses.
1964) and an increase in the antibody titer
and cell-mediated response (DTH) at 100 mg/kg body wt.
However, hemagglutination inhibition (HI) and/or microneutralization (MN) test results showed 7 persons had antibody titers
[greater than or equal to] 80 for subtype H5N2 virus; 6 of these persons showed seroconversion for the virus (Table 2).
Unfortunately, it was not possible to check her VZV antibody titers
before her recurrent varicella episode.
To evaluate the effect of the storage time on the anti-human-tTG titers, we compared the antibody titers
of the negative sera collected in 1991 with the antibody titers
of the sera collected in 2003 from 100 randomly selected individuals belonging to group 3.
2% of all travelers had a confirmed influenza virus infection, defined as a [greater than or equal to] 4-fold increase in antibody titers
, and an influenza incidence of 1.
HI titer 1:40 is defined as the proportion of subjects with a minimum post-vaccination HI antibody titer
against pneumococcal vaccine were measured at the Department of Immunology, Institute of Child Health (London, UK).
At 5 weeks post injection, it is found that microparticles with higher aspect ratios (ratio of its longer dimension to its shorter dimension) have significantly higher antibody titers
than particles with an aspect ratio of 1 or soluble protein.
To determine the seroprevalence of preexisting hemagglutinin inhibition (HAI) antibody titers
to influenza strains with pandemic potential, we tested serum samples for antibodies to A(H1N1)pdm09 virus and the 1918, 1957, and 1968 pandemic viruses.
