The Vaccination Act 1853 introduced compulsory smallpox vaccination in England and Wales.
It was accepted at the time, that voluntary vaccination had not reduced smallpox mortality, but the Vaccination Act 1853 was so badly implemented that it had little impact on the number of children vaccinated in England and Wales. In the United States of America compulsory vaccination laws were upheld in the 1905 landmark case Jacobson v.
For example, an 1853 law required universal vaccination against smallpox in England and Wales, with fines levied on people who did not comply.

Although it is possible to have aluminium toxicity, aluminium salts have been used effectively and safely since the 1930s when they were first used with the diphtheria and tetanus vaccines.
The deployment of a combined DPT vaccine against diphtheria, pertussis (whooping cough), and tetanus in the 1950s was considered a major advancement for public health.

In the 1960s six to eight children died each year in the United States from vaccination-related complications.

In 1977 the WHO recorded the last case of smallpox infection acquired outside a laboratory in Somalia.
When smallpox was finally eradicated in 1979, it had already killed an estimated 300–500 million people in the 20th century. Vaccination and immunization have a similar meaning in everyday language.

Despite improved DPT vaccines coming onto the market in the 1990s DPT vaccines became the focus of anti-vaccination campaigns in wealthy nations.
There was also a case in Texas in 2012 where 21 members of a church contracted measles because they chose not to immunize. ====Vaccination and autism==== The notion of a connection between vaccines and autism originated in a 1998 paper published in The Lancet whose lead author was the physician Andrew Wakefield.
The Vaccine for Children Program and the Social Security Act are two major players in supporting lower socioeconomic groups. In 2000, the CDC declared that measles had been eliminated in the US (defined as no disease transmission for 12 continuous months).
As immunization rates fell outbreaks of pertussis increased in many countries. In 2000, the Global Alliance for Vaccines and Immunization was established to strengthen routine vaccinations and introduce new and under-used vaccines in countries with a per capita GDP of under US$1000. ==Vaccination policy== To eliminate the risk of outbreaks of some diseases, at various times governments and other institutions have employed policies requiring vaccination for all people.
Even though evidence supports the safety and efficacy of thimerosal in vaccines, thimerosal was removed from childhood vaccines in the United States in 2001 as a precaution. === Monitoring === The administration protocols, efficacy, and adverse events of vaccines are monitored by organizations of the federal government, including the CDC and FDA, and independent agencies are constantly re-evaluating vaccine practices.

However, some diseases, such as measles outbreaks in America, have seen rising cases due to relatively low vaccination rates in the 2010s - attributed, in part, to vaccine hesitancy. The first disease people tried to prevent by inoculation was most likely smallpox, with the first recorded use of variolation occurring in the 16th century in China.
