Article Critique



Thepurpose of the article is to assess whether influenza vaccination inchildren is related to influenza and pneumonia illnesses in elderlypeople. The research was conducted between 2002 and 2006 where 5million hospital records from centers for Medicare and Medicaidservices were acquired. In this research, vaccination coverage datain children and adults was acquired from the national immunizationsurvey as well as the behavioral risk factor surveillance. Accordingto the research, child influenza vaccination had a negativeassociation with the age acceleration in influenza and pneumonia. Onthe other hand, influenza immunization among adults was notassociated with pneumonia and influenza in the elderly. As such, itwas concluded that influenza child vaccination is likely to inducegroup immunity among the older adults. Likewise, it proved to be morebeneficial to induce immunity among adults than preventing influenzaby vaccinating older adults themselves (Cohen et al, 2006).

Thedata for analysis was obtained from Medicaid and Medicare centers fora period of four years between 2002 and 2006. The records werearranged and summed in a single year distribution. The data wascompared to the counts on adults aged between 65 and 69 from thecensus bureau of statistics. The results from the statistics wasanalyzed and presented in tables. The relationship between influenzavaccination and pneumonia and influenza rate acceleration was alsoanalyzed and presented in tables to make it easy for all tounderstand the correlation. Clearly, it can be seen that greatervaccination coverage in children was associated with lower cases ofpneumonia and influenza among the older adults.

Althoughthe research was informative and is used as reference by many healthpractitioners in the related field, it has some limitations. Theinformation was based on immunization data for preschoolers agedbetween 19 to 35 months. The data on these preschoolers is notreadily available in the centers for immunization and relatedsources. Some of the data was obtained from phone surveys thus,subject to sampling error and recall bias. It is also notable thatthe research only focused on immunization against influenza, but didnot consider other immunizations that could have an impact onpneumonia and influenza among the older adults.

Further,acquisition of information from the Medicare was only availed for twoof the four years of study. The other place where the researchesacquired data was from the Census bureau. When comparing the two,there was a consistence discrepancy between the two denominators.This means that the results may have been inaccurate due tounderestimation. Similarly, the research did not take into accountwhether proper vaccines for influenza were used. The other majorlimitation of the research is that it did not consider seasons. Thereare seasons in which case influenza and pneumonia may be higher thanother seasons. States with high season of influenza may enhanceimmunization in the next season and vice versa. Consequently, thismay affect the viability of the results.

Allin all, despite the limitations, the information for the research iscredible. It offers a great opportunity for future research withregard to the relationship between influenza vaccination in childrenand adult hospitalization. Future study should consider the timelimit for research and other inherent limitations. With such results,it is possible for the government to act towards reducing cases ofpneumonia and influenza among the older adults and the generalpopulation accordingly.
