Pneumonia

Introduction and scale-up of pneumonia vaccines has the great impact for the poorest children

A study looking at the impact of pneumococcal vaccine introduction and scaling up pneumonia treatment in Ethiopia found that 30-40% of all deaths averted by these interventions would be expected to occur in the poorest wealth quintile. Scaling up PCV13 to levels achieved with DTP3 in Ethiopia would be expected to avert nearly 3000 child deaths and 60,000 episodes of pneumococcal pneumonia annually, not including any potential herd benefit. A publicly financed program to scale up pneumococcal vaccines would cost about US$40 per year of healthy life gained.

In Argentina, PCV immunization is a highly cost effective strategy

PCV7 use in Argentina resulted in an estimated cost of US$5,599 per life year gained. The purchase of the 4 doses of vaccine for the entire cohort at a cost of US$26.5 per dose would required an investment of US$73,823,806.00. This investment would significantly reduce the number of deaths brought about by cases of meningitis, bacteremia, pneumonia, otitis media and meningitis sequelae. The resultant decrease in morbidity and mortality coupled with herd immunity offered by immunization would contribute substantially to national productivity making PCV immunization a highly cost effective strategy.

Pneumonia vaccination among children in refugee camps is cost-effective

In a study modeling the cost-effectiveness of vaccination campaigns in Somalia – the country with the second largest number of refugees in 2012 – the use of Hib vaccine, PCV10, or both Hib and PCV10 were all found to be cost effective means to prevent excess morbidity and mortality from pneumonia in young Somali children. Such a vaccination campaign could conservatively reduce pneumonia cases and deaths by nearly 20%.

Vaccines are a cost-effective means to reduce the high burden of pneumonia and diarrhea suffered by malnourished children living in refugee camps

Children living in the Yida refugee camp in South Sudan in 2013 were found to have an elevated rate of pneumonia infections likely due to malnutrition, overcrowding, and inadequate shelter. Using these data, the CDC estimated that the use of Hib and pneumococcal vaccines in children under 2 years of age in the camp would be cost-effective under all dosing scenarios evaluated. Medecines Sans Frontiers (MSF) provided medical services to this refugee camp and found delivery of these vaccines to be feasible and effective in this setting.

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.
