Measles** Measles** At the same time, a variety of govermental agencies and regulations emerged to oversee the production and testing of vaccines. Countries on the Continent had been steadily moving to the use animal vaccine since the mid-1860s. H.M.

After mass inoculations began in 1954, everyone marveled at the high success rate–some 60-70 percent–until the vaccine caused a sudden outbreak of some 200 cases. Since the mid-1980s, many vaccines have been added to the schedule. Polio (OPV) The schedules are reviewed by committees of experts from the Centers for Disease Control and Prevention, the American Academy of Pediatrics, and the American Academy of Family Physicians. The Act did, however, offer free vaccination for infants (the first instance of free medical service in the country) and banned variolation, a move heralded by the medical profession. Weakened, or attenuated, vaccines consist of microorganisms that have lost the ability to cause serious illness but retain the ability to stimulate immunity. Varicella Hib Hib Diphtheria* Animals have been used in the study of health, illness, and death in humans for centuries - dating back to around 350 B.C., when the first known medical standards were developed by experimenting on pigs. The challenge in vaccine development consists in devising a vaccine strong enough to ward off infection without making the individual seriously ill. To that end, researchers have devised different types of vaccines. Pneumococcus Tetanus* Government Regulation. This activity is best viewed on larger screens. Important changes to the schedule between 1995 and 2010 included: Diphtheria* However, immunization of these groups didn't effectively stop transmission of hepatitis B virus. Cases of polio in the U.S. dropped from 14,647 in 1955 to 5,894 in 1956, and by 1959 some 90 other countries were using Salk’s vaccine. These included vaccines that protect against pertussis (1914), diphtheria (1926), and tetanus (1938). Another approach, called naked DNA therapy, involves injecting DNA that encodes a foreign protein into muscle cells. After it was determined that the cases were all caused by one faulty batch of the vaccine, production standards were improved, and by August 1955 some 4 million shots had been given. A few of the entries have been left out in order to provide a broad overview. Pertussis vaccine development took considerably longer, with a whole cell vaccine first licensed for use in the US in 1948. Smallpox The New York City Board of Health told the Health Department to devise a plan to ensure the purity and potency of diphtheria antitoxins sold in the city.

In the late 1940s, the March of Dimes, a grassroots organization founded with President Roosevelt’s help to find a way to defend against polio, enlisted Dr. Jonas Salk, head of the Virus Research Lab at the University of Pittsburgh. Influenza vaccines, available since the 1940s, are now recommended for most adults. The first formal adult immunization schedule was published in 2002 and is updated annually. It is somewhat humiliating to find that three of these are not conducted with such regard to hygienic precautions or even to ordinary cleanliness, as to warrant the Board in expressing anything but condemnation of the establishments themselves and of the methods pursued therein. Although the first vaccine against smallpox was developed in 1796, greater than 100 years later its use had not been widespread enough to fully control the disease (4).
