Prior to the measles vaccine, the United States alone had nearly 4 million cases of measles each year. The introduction of the vaccine led to a dramatic decline in measles cases.

The measles vaccine designed by the Nobel Prize winner's virologist John F. Enders was first approved in 1963, after which it was inoculated with a modified vaccine in 1968. The rubella vaccine started in 1969. In many countries, vaccines are combined into one vaccine. "MR" vaccine, or "MMR" vaccine mumps flu vaccine. Which government will decide which vaccine to use?

Today, the World Health Organization (WHO) encourages children to vaccinate two measles measles vaccines. WHO also recommends combining measles and rubella efforts. The measles and rubella program offers this opportunity for children all over the world. Vaccines are safe and effective, and if the population coverage rate is very high, viruses are blocked. Therefore, measles and rubella can be eliminated in a very high range

For example, in order to eliminate measles in the United States, we are trying to vaccinate pre-school and school-age children with high vaccines in this country. In the 1990s, countries in South America and Central America launched a campaign to vaccinate all young people from 9 months to 15 years to prevent the spread of measles virus quickly. This method is an important factor in eliminating measles in the Western Hemisphere (2002) and local rubella in 2016.

The measles and rubella program will raise measles - rubella vaccine from pharmaceutical companies and help provide it to countries organizing vaccination campaigns. The vaccines used in measles and rubella programs are safe and effective as validated by the World Health Organization.

This initiative, in cooperation with each country, also confirms that a system is in place to keep the vaccine at an appropriate temperature until it reaches the child who needs the vaccine. Both measles vaccine and rubella vaccine can be purchased and managed at a price of about $ 2. This is one of the most cost-effective medical interventions available today.

It is estimated that from 3 million to 4 million people are suffering measles every year in the United States before vaccination programs begin only in 1963. Approximately half a million people are reported each year annually to the Center for Disease Control and Prevention, 400 to 500 people are killed, 48,000 are hospitalized, and 1000 have measles encephalitis (swelling of the brain). Since then, the widespread use of the measles vaccine has reduced measles cases by more than 99% compared to the pre-vaccination era. However, measles are still common in other countries. Non vaccinated people continue to infect measles abroad and bring this disease to the United States and continue spreading it to others.

It is estimated that more than 3 million people are measles infected every year in the decade before MMR (measles-mumps-rubella) vaccine is introduced in the United States. As MMR is widely used, measles cases in this country have declined by more than 99%. In the United States, it was announced that the spread of measles in the measles was eliminated in 2000. However, travelers from overseas still import cases. According to the US Centers for Disease Control, approximately 50% of measles cases imported in the United States come from US residents of other countries. Encourage US residents to travel outside the US to confirm immunity to measles before traveling by previous infection or vaccination

Prior to the availability of the measles vaccine in the United States in the mid-1960s, it was reported that 450 deaths and 4,500 cases of encephalitis were caused by measles every year. This is a type of brain inflammation. By 2000, measles were eliminated due to the nearly universal vaccination in the United States. Since then, the incident occurred occasionally. Normally the victim is infected with such incident abroad or because people with measles have entered the United States. Approximately 63 cases have been reported every year from 2000 to 2007.
