The historical impact of measles before the widespread of vaccination in 1963, lead to major epidemics approximately cause every 2 to 3 years causing recorded by the mortality rate mostly children as estimated death each year was 2.6 million.

Measles was one of the most deadly infectious diseases in history, claiming the lives of millions of people over the centuries. Before the widespread use of vaccination, measles epidemics were a common occurrence, and they had a significant impact on society. The disease was highly contagious and could spread quickly through communities, often affecting children and young adults.

Measles outbreaks were particularly devastating in areas of high population density, such as cities and towns. In the early 1900s, for example, New York City recorded an average of 500 deaths and 150,000 cases of measles each year. The disease was also a major cause of infant mortality, with many babies dying before they reached their first birthday.

The impact of measles was not just limited to the loss of life. The disease often left survivors with long-term health problems, including hearing loss, blindness, and brain damage. In addition, measles epidemics often led to disruptions in society, such as school closures and economic decline.

The introduction of the measles vaccine in 1963 marked a turning point in the fight against the disease. The vaccine was highly effective at preventing infection, and its widespread use led to a dramatic reduction in the number of cases and deaths from measles. Nonetheless, measles remains a significant health threat in some parts of the world, particularly where vaccination rates are low.

The historical impact of measles before the widespread use of vaccination in 1963 was significant. Here is a step-by-step breakdown:

1. Major Epidemics: Measles caused major epidemics approximately every 2 to 3 years. These epidemics led to a significant number of cases and had a profound impact on public health.

2. Mortality Rate: The mortality rate of measles was particularly alarming, especially among children. The recorded mortality rate during this time was mostly among children, and the estimated annual death toll was around 2.6 million.

3. Children as the Main Victims: Measles had a disproportionate impact on children, as they were more susceptible to the disease. This vulnerability meant that children made up a significant proportion of the affected population.

4. Lack of Vaccination: The reason behind the high mortality rate and frequent epidemics was the lack of widespread vaccination. Before the introduction of vaccines, people had limited protection against measles, making it easier for the disease to spread and cause severe illness and death.

5. Impact on Public Health: The consequences of measles epidemics were far-reaching. Beyond the loss of lives and the suffering experienced by individuals and families, these epidemics put a strain on healthcare systems and had economic implications.

6. Introduction of Measles Vaccination: In 1963, a measles vaccine was introduced, which marked a turning point in the battle against this disease. The widespread use of vaccination drastically reduced the number of measles cases and associated deaths worldwide.

It is important to note that while measles vaccination has been successful in reducing the impact of the disease, vigilance is still required to maintain high vaccination rates and prevent future outbreaks.
