Immunity of children to diphtheria, tetanus, and poliomyelitis.
A survey of titres of diphtheria and tetanus antitoxins and of antibodies to polioviruses in the sera of 291 schoolchildren aged 15, 11, and 7 years showed that high immunisation rates can evoke protective concentrations of tetanus antitoxin in 98% of children and protective levels of the antibodies to diphtheria and all three types of poliomyelitis in 85% of children. Reinforcing immunisation ...متن کامل
BACKGROUND Large-scale vaccination programmes have been carried out for a long time in Sweden, as in many other countries. However, often little is known of the effects of these vaccinations. During 1990 and 1991 a survey of immunity based on a random adult population sample was carried out. The main purpose was to estimate the level of immunity to diphtheria, tetanus and polio of the adult pop...متن کامل
INTRODUCTION Vaccinations in school-aged children are required by state and local law to maintain high vaccination coverage rates, as well as low rates of vaccine-preventable diseases. Diphtheria, tetanus, and pertussis are childhood diseases that can be life threatening; poliomyelitis, another childhood disease, can be disabling. In turn, vaccinations were developed to provide protection again...متن کامل
BACKGROUND During 1990 and 1991 a survey of immunity was carried out in Sweden. The main purpose was to estimate the level of immunity to diphtheria, tetanus and polio in the adult population. In total, 4800 people, randomly selected according to a stratified, two-stage, sampling plan, were contacted and asked to contribute a blood sample. Of those selected, 70.6% gave a blood sample. METHODS...متن کامل
Post-vaccinal Immunity to Diphtheria, Measles, Tetanus and Pertussis in Children Exposed to Environmental Chemical Factors1
An assessment of post-vaccination immunity against diphtheria, measles, tetanus and pertussis in children with increased levels of chemical toxicants, caused by environmental exposure, determined that the levels of postvaccination antibodies in this group of children were significantly lower than those in children living in environmentally favorable areas and that disorders in the development o...متن کامل
