Insights
Pediatric influenza is common, affecting healthy children and those with chronic conditions. Further research is needed to identify ideal influenza vaccines for all children.
Area of Science:
- Pediatric infectious diseases
- Vaccinology
- Public health
Background:
- Pediatric influenza presents high attack rates, especially during pandemics.
- Severe influenza and related complications affect both healthy children and those with chronic conditions.
- Annual mortality rates are similar between these two pediatric groups.
Purpose of the Study:
- To review characteristics of pediatric influenza vaccines.
- To evaluate the prevention efficacy, safety, and tolerability of various vaccine formulations and adjuvants.
- To identify optimal influenza vaccines for the pediatric population.
Main Methods:
- Literature review of existing studies on pediatric influenza vaccines.
- Analysis of data on vaccine efficacy, effectiveness, immunogenicity, and safety.
- Comparative evaluation of different vaccine formulations and adjuvants.
Main Results:
- Current influenza vaccines vary in characteristics, impacting their suitability for pediatric use.
- Data on efficacy, effectiveness, immunogenicity, and safety across different formulations and adjuvants are crucial.
- There is a need for more comprehensive data to guide vaccine selection.
Conclusions:
- Further studies are required to collect robust efficacy, effectiveness, immunogenicity, and safety data.
- Identifying ideal pediatric influenza vaccines will significantly benefit public health.
- Optimized vaccines could offer substantial advantages for widespread use in children.
Abstract:
Pediatric influenza is a very common disease: attack rates range from 23% to 48% during interpandemic years and are significantly higher during pandemics. Influenza-related complications seem to be more common in children at risk because of an underlying chronic severe disease, but recently collected data clearly demonstrate that otherwise healthy children can also suffer from severe influenza and that the annual number of deaths is no different between the two groups. The aim of this review is to discuss the characteristics of all influenza vaccines in order to evaluate the real likelihood of prevention, as well as the safety and tolerability of the different formulations and adjuvants. The data indicate that further studies collecting efficacy and effectiveness data and evaluating the immunogenicity and safety of the different formulations and adjuvants should lead to the identification of more ideal influenza vaccines that could be used with significant advantage in the entire pediatric population.
