I regret that it has not been possible for me to deliver in person my greetings and best wishes to the International Conference on Measles Immunization. Your meeting brings together leading scientific minds of 20 nations. Your purpose is to advance the health of all people everywhere and especially to protect children against a formidable and widespread threat. Such meetings and such goals transcend national boundaries and unite mankind in our common striving toward a better life.
John F. Kennedy President of the United States
