International Sanitary Conventions (1933–1951) The International Certificate of Inoculation and Vaccination was established by the
International Sanitary Convention for Aerial Navigation (1933) in
The Hague, which came into force on 1 August 1935 and was amended in 1944. After
the 1944 amendment, in addition to Personal, Aircraft and Maritime Declarations of Health, the Convention covered five certificates: • International Certificate of Inoculation Against
Cholera. • International Certificate of Inoculation Against
Yellow Fever. • International Certificate of Immunity Against Yellow Fever. • International Certificate of Inoculation Against
Typhus Fever. • International Certificate of Vaccination Against
Smallpox.
International Sanitary Regulations (1951–1969) The
World Health Organization (WHO) was formed by its constitution on 22 July 1946, effective on 7 April 1948. The WHO Constitution included stipulations
to stimulate and advance work to eradicate epidemic, endemic and other diseases (Article 2.g) and that the
World Health Assembly would
have authority to adopt regulations concerning sanitary and quarantine requirements and other procedures designed to prevent the international spread of disease (Article 21.a). The Fourth World Health Assembly adopted the International Sanitary Regulations (alias WHO Regulations No. 2) on 25 May 1951,
replacing and completing the earlier International Sanitary Conventions. It confirmed the validity and use of international certificates of vaccination (Article 115), and updated the old model with a new version (Appendices 2, 3, 4). The certificates mentioned were used for proof of vaccination against diseases such as cholera, yellow fever and smallpox; the term
inoculation was no longer used. On 23 May 1956, the Ninth World Health Assembly amended the form of the International Certificate of Vaccination or Revaccination against Smallpox per 1 October 1956.
International Health Regulations (1969–present) The WHO's
World Health Assembly adopted the
International Health Regulations (IHR) in 1969, succeeding the previous International Sanitary Conventions/Regulations. The World Health Assembly determined in 1973 that
vaccination against cholera was unable to prevent the introduction of cholera from one country to another, The ICV was most successful in the case of smallpox. The mandatory possession of vaccination certificates significantly increased the number of travellers who were vaccinated, and thus contributed to preventing the spread of smallpox, especially when the
rapid expansion of air travel in the 1960s and 1970s reduced the travelling time from endemic countries to all other countries to just a few hours. After smallpox was successfully eradicated in 1980, the International Certificate of Vaccination against Smallpox was cancelled in 1981, and the new 1983 form lacked any provision for smallpox vaccination. == Contents ==
