Immunizations are a very important part of the public health system at all population levels. At an individual level immunizations promote health by preventing certain diseases from occurring. At a community level immunizations work to create herd immunity which helps to protect individuals who aren't able to be vaccinated. According to the text "herd immunity is a state in which those not immune to an infectious agent will be protected if a certain proportion (generally considered to be 80%) of the population has been vaccinated or is otherwise immune" (Nies & McEwen, 2011, p. 496). At a national level immunization efforts can cause elimination of a certain disease within a specific geographic area and at a world-wide level immunizations can lead to eradication (Nies & McEwen, 2011).
There is no doubt that immunizations are an extremely important aspect of public health and it is important that all populations are aware of these benefits and have access to vaccination services. One specific intervention from the public health wheel that could be beneficial when discussing immunization efforts is outreach. "Outreach locates populations of interest at risk and provides information about the nature of concern, what can be done about it and how services can be obtained" (Nies & McEwen, 2011, p. 15). In order to successfully implement an outreach plan basic steps much be taken.
The first step in outreach is identifying the problem, in this case immunizations. Then we must locate a population at risk such as a community with limited access to health care services or one that lacks knowledge about vaccinations. After identifying the problem and population it is necessary to determine interest and learning needs. Tailoring a plan specific to a population promotes adherence. For any outreach plan to be successful there needs to be adequate resources, funds and people involved. In order for a successful outreach plan to be implemented all these components and others must work together to meet a common goal.
A real life example can be taken from an article from the American Journal of Public Health. This article discusses attempts made to improve childhood immunization practices in an urban city in New York. The plan, Start Right, was implemented in a Latino urban community where vaccination rates were very low. The program relied upon outreach, education and immunization reminders to increase immunization rates among children. Upon evaluation the plan appears to be successful. The children in the Start Right program were 53% more likely to be up-to-date on immunizations when compared to children in the controlled group (Findley, 2008). As seen through this specific study outreach interventions can be successful in improving immunization efforts.
