Question 2

Now that we have studied the various types of vaccines, consider the current resurgence of diseases like the measles. How can we convince the general public and possibly even ourselves, that immunization is a necessary preventative measure for diseases that have serious complications? Is there a different schedule that we should consider? Are some forms of vaccines safer than others? Should we spread out the inoculation schedule to prevent confusion of a young person? (Include terms such as live attenuated, killed or inactive, subunit, toxoid, conjugate, complications of measles, risks to others if uninoculated, risks to individuals that do get inoculated). You are encouraged to use your text and outside sources to develop your informed answer. Use facts and concepts.
