Targeted immunization strategies
open-in-new
<p>Targeted immunization strategies are approaches designed to increase the <a href="/facts/Immunization/f2NLoleW">immunization</a> level of populations and decrease the chances of <a href="/facts/Epidemic/N7fM3HYd">epidemic</a> <a href="/facts/Outbreaks/CBLtnobw">outbreaks</a>. Though often in regards to use in healthcare practices and the administration of vaccines to prevent biological epidemic outbreaks, these strategies refer in general to immunization schemes in <a href="/facts/Complex_networks/6zTa9z4e">complex networks</a>, biological, social or artificial in nature. Identification of at-risk groups and individuals with higher odds of spreading the disease often plays an important role in these strategies, since targeted immunization in high-risk groups is necessary for effective eradication efforts and has a higher return on investment than immunizing larger but lower-risk groups. </p>
