Measles vaccine is a highly effective vaccine used against measles.[1] The measles-mumps-rubella-varicella combo (MMRV vaccine) vaccine has been available since 2005. The vaccine acts by stimulating the adaptive immune response and provides long term protection against the disease. The onset of the protection is slow but the effect is long lasting. It is on the World Health Organization's List of Essential Medicines, a list of the most important medication needed in a basic health system.[2]

Effectiveness[edit]

Measles cases 1944-1964 follow a highly variable epidemic pattern, with 150,000-850,000 cases per year. A sharp decline followed introduction of the vaccine in 1963, with fewer than 25,000 cases reported in 1968. Outbreaks around 1971 and 1977 gave 75,000 and 57,000 cases, respectively. Cases were stable at a few thousand per year until an outbreak of 28,000 in 1990. Cases declined from a few hundred per year in the early 1990s to a few dozen in the 2000s.
Measles cases reported in the United States before and after introduction of the vaccine.

Before the widespread use of a vaccine against measles, its incidence was so high that infection with measles was felt to be "as inevitable as death and taxes."[3] Today, the incidence of measles has fallen to less than 1% of people under the age of 30 in countries with routine childhood vaccination.[citation needed] In the United States, reported cases of measles fell from hundreds of thousands to tens of thousands per year following introduction of the vaccine in 1963 (see chart at right). Increasing uptake of the vaccine following outbreaks in 1971 and 1977 brought this down to thousands of cases per year in the 1980s. An outbreak of almost 30,000 cases in 1990 led to a renewed push for vaccination and the addition of a second vaccine to the recommended schedule. Fewer than 200 cases have been reported each year since 1997, and the disease is no longer considered endemic in the United States.[4][5][6]

The benefit of measles vaccination in preventing illness, disability, and death has been well documented. The first 20 years of licensed measles vaccination in the U.S. prevented an estimated 52 million cases of the disease, 17,400 cases of mental retardation, and 5,200 deaths.[7] During 1999–2004, a strategy led by the World Health Organization and UNICEF led to improvements in measles vaccination coverage that averted an estimated 1.4 million measles deaths worldwide.[8] The vaccine for measles has led to the near-complete elimination of the disease in the United States and other developed countries.[9] It was introduced in 1963.[10] These impressive reductions in death and long-range after-effectiveness were initially achieved with a live virus version of the vaccine that itself caused side effects, although these are far fewer and less serious than the sickness and death caused by measles itself. While preventing many deaths and serious illnesses, the live virus version of the vaccine did cause side effects in a small percentage of recipients, ranging from rashes to, rarely, convulsions.[11]

Measles is endemic worldwide. Although it was declared eliminated from the U.S. in 2000, high rates of vaccination and good communication with persons who refuse vaccination are needed to prevent outbreaks and sustain the elimination of measles in the U.S.[12] Of the 66 cases of measles reported in the U.S. in 2005, slightly over half were attributable to one unvaccinated individual who acquired measles during a visit to Romania.[13] This individual returned to a community with many unvaccinated children. The resulting outbreak infected 34 people, mostly children and virtually all unvaccinated; 9% were hospitalized, and the cost of containing the outbreak was estimated at $167,685. A major epidemic was averted due to high rates of vaccination in the surrounding communities.[12]

Adverse Effects[edit]

Subacute sclerosing panencephalitis[edit]

Contraindications[edit]

Important drug interactions[edit]

Types[edit]

Measles is rarely given as individual vaccine nowadays and is often given in combination with mumps and rubella. Two types of vaccines are available for measles currently.

Measles mumps rubella vaccine (MMR-II); MMR vaccine is a live attenuated viral vaccine used to induce immunity against measles, mumps and rubella.

Dosing[edit]

MMR is not given to children less than 12 months age. Pediatric dosing is 0.5 ml subcutaneously (often between 12–18 months). A second dose is given on the 11th or 12th birthday. Vaccine is administered in the outer aspect of the upper arm. In adults, 0.5 mL subcutaneously and a second dose 28 days apart is given. In adults greater than 50 years, only one dose is needed.

History[edit]

As a fellow at Children's Hospital Boston, Dr. Thomas C. Peebles worked with Dr. John Franklin Enders, known as "The Father of Modern vaccines", who earned the Nobel Prize in 1954 for his research on cultivating the polio virus that led to the development of a vaccination for the disease. Switching to study measles, Peebles was sent to a school where an outbreak of the disease was under way and was able to isolate the virus from some of the blood samples and throat swabs he had taken from students. Even after Enders had taken him off the study team, Peebles was able to cultivate the virus and show that the disease could be passed on to monkeys inoculated with the material he had collected.[9] Enders was able to use the cultivated virus to develop a measles vaccine in 1963 based on the material isolated by Peebles.[15] In the late 1950s and early 1960s, nearly twice as many children died from measles as from polio.[16] The vaccine Enders developed was based on the Edmonston strain of attenuated live measles virus, which was named for the student from which Peebles had taken the culture that led to the virus' cultivation.[17]

The first ever trials of measles vaccine were undertaken by David Morley at the Wesley Guild Hospital in Ilesha, Nigeria[18] on his own children.

Dr. Maurice Hilleman of Merck & Co., a pioneer in the development of vaccinations, developed the MMR vaccine in 1971, which treats measles, mumps and rubella in a single shot followed by a booster.[11][19] One form is called "Attenuvax" with more than 40 peptide sequences.[20] The measles component of the MMR vaccine uses Attenuvax, which is grown in a chick embryo cell culture using the Enders' attenuated Edmonston strain.
