=== Common Misconceptions Surrounding Vaccines ===
−
Many people assume that official vaccine recommendations are based on recommendations of independent panels of experts after reviewing risk-benefit and cost-benefit analyses. They are not. The government panels are dominated by vaccine industry representatives and they have no consumer representatives.{{cn}}

Vaccines have injured many in the developing world, sometimes due to contamination in donated stale vaccines. The vaccine was banned for over a year in Nigeria after concerns about safety were raised. The ban has since been lifted, but the vaccination rate remains low.{{cn}}

For example, in 1962 Japan instituted mandatory vaccination against influenza in schoolchildren. This continued until 1987 when the program was changed to optional; it was abandoned in 1994. Approximately 85 percent of children were estimated to have been vaccinated.<ref>{{hnb|Glezen|2004}}</ref> Several studies examined the mortality rates due to influenza during this period of time and revealed that the death rates due to influenza in all population groups were drastically decreased, including older adult populations. Since there was no increased rate of vaccination in these populations, the decreased mortality was caused by herd immunity effects of vaccinating so many children.<ref>http://www.newsrx.com/newsletters/Vaccine-Weekly/2001-04-11/200104113335VW.html Mandatory Vaccination of Japanese Schoolchildren Demonstrates "Herd Immunity"</ref> Many researchers have written that this and other evidence argues strongly for mandatory vaccination programs worldwide as a means of controlling many diseases and preventing a [[pandemic]].<ref>http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=1360502 Herd Immunity</ref>

The USA has federal vaccination recommendations according to an official CDC schedule. Requirements are up to the states, as explained by the [[CDC]]: "All 50 states and the District of Columbia (DC) have state laws that require children entering childcare or public schools to have certain vaccinations. There is no federal law that requires this."<ref>https://www.cdc.gov/vaccines/vpd/mmr/public/index.html</ref> Most states have medical and religious exemptions. Some states make it very easy to opt out of vaccines, while other states strictly enforce compliance for school attendance. The difference in vaccination rates between these states is actually very slight, and usually not nearly enough to affect herd immunity.{{cn}}

As of February 2008, the CDC noted that "fewer than 100 measles cases are now reported annually in the United States and virtually all of those are linked to imported cases" in which someone is infected during overseas travel.
