Undernourished children have a higher likelihood for diarrhea and pneumonia but immunization can improve infant growth

Multiple studies show that

  1. Diarrhea and pneumonia impair children’s growth and that underlying malnutrition is a major risk factor for these conditions.
  2. “Episodes of diarrhea may predispose to pneumonia in undernourished children” and
  3. Immunization against influenza (in mothers) and Streptococcus pneumoniae may improve infant growth. In addition, new studies from Bangladesh, Colombia, Ghana, and Israel further support the paradigm that malnutrition is a key risk factor for diarrhea and pneumonia.

PCV vaccination at day-care centers reduced antibiotic use in children

Evaluation of the ability of pneumococcal conjugate vaccine to reduce the occurrence of respiratory infections and the resultant antibiotic drug use was conducted among day care attendees in Israel. It was observed that children who had received the 9-valent conjugate vaccine showed a 17% overall reduction in antibiotic usage. In particular, a 10% reduction in days of antibiotic usage for upper respiratory tract infections, 47% fewer days of antibiotic usage for lower respiratory tract infections, and 20% fewer days of antibiotic usage for otitis media (ear infections) when compared to children who did not receive PCV.
