Vaccine Coverage Essay

698 words - 3 pages

This is the first study to evaluate influenza vaccine coverage in Thailand. Our study found that the quantity of publicly-purchased influenza vaccines has increased by 39% from 2010 to 2012 in Thailand. From 2010 to 2012, vaccine wastage also increased (trend p <0.05), and averaged 9.5%. While influenza coverage has risen among persons with a chronic disease and elderly persons aged ≥65 years, it has decreased for all other high-risk groups. However, persons with a chronic disease and elderly persons aged ≥65 years were the designated influenza vaccine priority groups in Thailand, which may explain why these groups have higher coverage than all other target groups.
The distribution of publicly-purchased influenza vaccine to high risk groups is a relatively new initiative in Thailand. With support from WHO and the U.S. government, in 2006, Thailand’s Government Pharmaceutical Company began building domestic capacity to produce influenza vaccine, with the aim of producing seasonal vaccine that can be converted to pandemic vaccine when the need arises[6]. Under this plan, in 2008, Thailand National Health Security Office began to purchase seasonal vaccines for elderly persons aged ≥65 years and persons with a chronic disease. In 2009, this was expanded to provide vaccines to pregnant women, young children aged 6 months to 23 months, obese persons, and mentally disabled persons. However, elderly persons and persons with a chronic disease have remained the priority groups for influenza vaccine coverage.
While influenza vaccination is increasing globally [14], coverage among high-risk groups varies widely. One study on vaccine coverage in Germany, Spain, Italy, the UK, and France, estimated that during the 2006/2007 influenza season, vaccine coverage among elderly persons aged ≥65 years and persons with a chronic disease was 18.5% and 16.5%, respectively [15]; this is similar to the findings of our study. In contrast, in comparison to Thailand, the US has much higher vaccine coverage: vaccine coverage among children aged 6 months to 23 months, elderly persons aged ≥65 years, and pregnant women, were estimated to be 76.9% (2012/2013), 66.2% (2012/2013), and 43% (2011/2012), respectively [16], [17]. ...
