Merck & Company's Development of Gardasil

Merck & Company’s Development of Gardasil In 2006, the United States branch of Merck & Co. received FDA approval for Gardasil, a human papillomavirus, or HPV, vaccine that protects against HPV and the cervical cancer that can come with it. In 1891, George F. Merck founded the US branch of the company to distribute chemicals with high purity for use in research, in New York City, New York, and other areas nearby. HPV is a common sexually transmitted infection that can cause genital warts, regular skin warts, cervical cancer, and other cancers. Since 2016, Gardasil has been the only HPV vaccine in use in the US and over people received 28 million doses in the country between 2014 and 2017, reducing people’s chances of contracting cancer.

Karl Landsteiner (1868-1943)

Karl Landsteiner (1868-1943) Karl Landsteiner studied blood types in Europe and in the United States in the late nineteenth and early twentieth centuries. Landsteiner won the Nobel Prize in Physiology or Medicine in 1930 for detailing immunological reactions in the ABO blood group system. The ABO blood group system divides human blood into one of four types based on the antibodies that are present on each cell. Landsteiner's work with blood types led physicians to safely perform blood transfusions and organ transplants. Additionally, Landsteiner researched the Rh blood factor, a protein marker on the surface of blood cells and that can impact pregnancy.
