![]() ![]() ![]() Important changes to the schedule between 19 included: ** Given in combination as MMR Annual updates to the immunization schedule - 1995 to 2010Īs more vaccines became available, an annual update to the schedule was important because of changes that providers needed to know, such as detailed information about who should receive each vaccine, age(s) of receipt, number of doses, time between doses, or use of combination vaccines. Following this recommendation, hepatitis B disease was virtually eliminated in children less than 18 years of age in the United States. The change of recommendation to immunize all infants in 1991 was the result of these failed attempts to control hepatitis B by only immunizing high-risk groups. That’s because about one-third of patients with acute disease were not in identifiable risk groups. ![]() However, immunization of these groups didn't effectively stop transmission of hepatitis B virus. The hepatitis B vaccine was not new, as it had been licensed in 1981 and recommended for high-risk groups such as infants whose mothers were hepatitis B surface antigen positive, healthcare workers, intravenous drug users, homosexual men and people with multiple sexual partners. When the schedule was published again in 1994, the hepatitis B vaccine had been added. The vaccine for Haemophilus influenzae type b was licensed in 1985 and placed on the recommended schedule in 1989. ** Given in combination as MMR Vaccine development in the 1980s - hepatitis B and Haemophilus influenzae type b While vaccine research continued, new vaccines were not introduced during the 1970s. Because of successful eradication efforts, the smallpox vaccine was no longer recommended for use after 1972. * Given in combination as DTP The 1970s - vaccine successĭuring the 1970s, one vaccine was eliminated. These three vaccines were combined into the MMR vaccine by Dr. In 1963, the measles vaccine was developed, and by the late 1960s, vaccines were also available to protect against mumps (1967) and rubella (1969). * Given in combination as DTP More vaccines followed in the 1960s - measles, mumps and rubella When the polio vaccine was licensed in 1955, the country celebrated, and Jonas Salk, its inventor, became an overnight hero. They waited for a vaccine, closely following vaccine trials and sending dimes to the White House to help the cause. Parents were scared of the polio epidemics that occurred each summer they kept their children away from swimming pools, sent them to stay with relatives in the country, and clamored for an understanding of the spread of polio. * Given in combination as DTP The vaccine everyone was waiting for - polio vaccine These three vaccines were combined in 1948 and given as the DTP vaccine. These included vaccines that protect against pertussis (1914), diphtheria (1926), and tetanus (1938). The next routinely recommended vaccines were developed early in the 20th century. However, by the late 1940s, scientific knowledge had developed enough, so that large-scale vaccine production was possible and disease control efforts could begin in earnest. The method Jenner tested involved taking material from a blister of someone infected with cowpox and inoculating it into another person’s skin this was called arm-to-arm inoculation. He did his study in 1796, and although he did not invent this method, he is often considered the father of vaccines because of his scientific approach that proved the method worked. Edward Jenner was the first to test a method to protect against smallpox in a scientific manner. ![]()
