when did the first hpv vaccine come out
HPV vaccines The first HPV vaccine became available in 2006.[1][7] As of 2017, 71 countries include it in their routine vaccinations, at least for girls.[1] They are on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system.[8] The wholesale cost in the developing world is about US$47 a dose as of 2014.[9] In the United States it cost more than US$200.[10] Vaccination may be cost effective in the developing world.[11]
Diphtheria Between 1910 and 1911, Béla Schick developed the Schick test to detect pre-existing immunity to diphtheria in an exposed person. Only those who were not exposed to diphtheria were preferably vaccinated. A massive, five-year campaign was coordinated by Dr. Schick. As a part of the campaign, 85 million pieces of literature were distributed by the Metropolitan Life Insurance Company with an appeal to parents to "Save your child from diphtheria." A vaccine was developed in the next decade, and deaths began declining significantly in 1924.[45]
