Prevent Measles Getting vaccinated is the best way to prevent
measles. The vaccine contains live viruses that can no longer
cause disease. - 12-15 months - 4-6 years (or at 11-12 years) In
some cases, the vaccine is given within three days after
exposure. This can prevent or reduce symptoms. Immune globulin
is given to certain unvaccinated people within six days of
exposure. This is usually for infants and pregnant women. Ask
your doctor if the vaccine is right for you. In general, avoid
the vaccine if you: - Have had severe allergic reactions to
vaccines or vaccine components - Are pregnant-Avoid pregnancy
for 1-3 months after receiving the vaccine. - Have a weakened
immune system - Have a high fever or severe upper respiratory
tract infection If you are not vaccinated, avoid contact with
someone who has measles.
