More Low-Income Kids Are Getting Vaccinated
The immunization gap between wealthier, poorer children is shrinking, study finds
For example, immunity in some of the children against certain types of polio was only around 50 percent. The study included children adopted from China, Russia and Guatemala. Children from China were the most likely to be lacking protective immunity. The researchers suggested that children adopted from other countries should be tested to assess their protective immunity, and if necessary, be revaccinated.
A third study looked at the order in which two immunizations are given, to see if there was any difference in babies' pain levels. Pain levels were assessed using a visual pain scale and whether or not the baby cried.
The Canadian researchers found that pain was reduced when the pneumococcal-conjugate vaccine (PCV) was given after the diphtheria, polio, tetanus, pertussis and Haemophilus-influenzae type b (DPTaP-Hib) vaccine.
