The changes in the serum immunoglobulin (Ig) level and in the measles antibody titer were examined with colony-born infant cynomolgus monkeys from 0 day to 26 weeks in age. In addition, their mother-monkey's milk was analyzed for Ig. The decrease in the IgG level after birth was more remarkable in the infants born with high IgG levels than those born with low IgG levels. The IgM level prominent...

Experiments were conducted to compare clostridial antibody response of beef heifers that do and do not develop injection-site lesions, evaluate long-term antibody response of a single- and multiple-dose toxoid, and evaluate the ability of a clostridial toxoid to elicit an active antibody response in newborn calves. In Exp. 1, 37 weaned heifers were vaccinated (d 0) with a clostridial vaccine (A...

Two canine distemper virus (CDV) vaccine types are currently commercially available: modified-live virus (MLV) vaccines and a canarypox recombinant CDV (rCDV) vaccine (Recombitek, Merial). This study compared the ability of the rCDV vaccine and MLV vaccines to significantly enhance (boost) the antibody response of previously immunized adult and juvenile dogs. A significant (fourfold or greater)...

Artery Disease To the Editor: Recently, Ridker et al published their observations about cytomegalovirus (CMV) and atherosclerosis.1 They found that “there is no evidence of a positive association between baseline IgG antibodies directed against CMV or HSV [herpes simplex virus] and the development of future MI [myocardial infarction] or thromboembolic stroke. Furthermore, we found no evidence o...

The objective of this study was to evaluate and compare the safety, tolerability and immunogenicity for two seasonal influenza subunit vaccines, one with MF59 adjuvant (Fluad) and one without an adjuvant (Agrippal). A total of 195 subjects aged > or = 65 years were enrolled to receive one dose of vaccine intramuscularly, 96 were vaccinated with Fluad, 99 received Agrippal. Blood samples were ta...

BACKGROUND AND AIMS The duration of the protection of hepatitis B vaccination for infants and the necessity of a booster dose administration is unknown. The aim of the present study was to evaluate the persistence of seroprotection after hepatitis B virus (HBV) vaccination in order to determine the necessity of a single booster dose in 5- to 7-year-old children. METHODS This clinical trial st...

OBJECTIVES In long-term botulinum neurotoxin treatment, loss of therapeutic efficacy may occur due to neutralising antibody formation. Preliminary results with incobotulinumtoxinA, a preparation free of complexing/accessory proteins, have indicated a low antigenicity. We hypothesised that continuous treatment with this botulinum neurotoxin preparation would not result in an increase in neutrali...

Hepatitis B remains a global burden, with estimated 15 to 40 percents of infected individuals eventually suffer from liver cirrhosis, liver failure, and hepatocellular carcinoma. Vaccination aims to form anti-HBs antibody with protective titer to prevent infection. CD4 T cell lymphocytes are known to play a major role in establishing immunity after vaccination. This study aimed to investigate p...
