Persistence of antibody after accelerated immunisation with diphtheria/tetanus/pertussis vaccine.

Persistence of antibody after accelerated immunisation with diphtheria/tetanus/pertussis vaccine.

OBJECTIVE To determine the persistence of antibody to diphtheria, tetanus, and pertussis in children receiving an accelerated schedule of primary immunisation. DESIGN Controlled study of antibody testing of blood samples from children immunised according to various schedules: three doses of triple vaccine completed at 8-13 calendar months, 6-7 calendar months, before 6 calendar months, or thr...

Antibody persistence and Haemophilus influenzae type b carriage after infant immunisation with PRP-T.

OBJECTIVES To assess the persistence of serum Haemophilus influenzae type b antibodies and the prevalence of H influenzae type b carriage in a group of preschool age children previously vaccinated in infancy. DESIGN Names were randomly selected from immunisation records. Families were visited on five occasions over a period of 12 months and throat swabs were taken from all family members pres...

Persistence of vaccine-induced antibody to measles 26-33 years after vaccination.

Because measles-specific antibody titer after vaccination is lower than after natural infection, there is concern that vaccinated persons may gradually lose protection from measles. To examine the persistence of vaccine-induced antibody, participants of a vaccine study in 1971, with documentation of antibody 1-7 years after vaccination, were followed up in 1997-1999 to determine the presence an...

Immunisation of Sheep and Goats with a Combined Clostridial and Anthrax Vaccine

Immunogenicity and safety of PRP-T conjugate vaccine given according to the British accelerated immunisation schedule.

The immunogenicity and safety of a new Haemophilus influenzae type b conjugate vaccine, PRP-T, was studied in 107 infants from the Oxford district. The vaccine was given concurrently with diphtheria, pertussis, tetanus, and polio vaccines at 2, 3, and 4 months of age. Symptoms after immunisation were recorded by a parent. Sera were obtained before the first immunisation and at 5 months of age a...
