In recent months, measles has spread throughout the country, mainly in the Jerusalem area. The Ministry of Health has launched an immunization campaign to raise the percentage of people immunized against the disease. The data shows that among those infected with the measles outbreak there are 5% -10% who were vaccinated against the disease. This is because the vaccine is not 100% effective. One dose of the vaccine is 93% effective and two doses are 97% effective. Also, there are people who do not acquire immunity after both doses.
