Vaccination Is Your Best Protection Against Measles

You have probably heard about the measles outbreaks happening in certain areas of the United States. These outbreaks continue to expand, and one confirmed death from measles has been reported so far.

The best way to defend against catching this very contagious and dangerous disease is to be properly vaccinated. All U.S. residents should be up-to-date on their MMR (measles, mumps, rubella) vaccinations. This is especially important if you are traveling outside the United States, no matter what your destination, or if you are traveling to an area within the United States with an active measles outbreak.

Most recent cases of measles in this country have been among children who have not received the MMR vaccine. Measles can cause severe health problems, including pneumonia, brain swelling, and sometimes death. The virus is spread by direct contact with an infected person or by infectious droplets in the air when someone with measles breathes, coughs, or sneezes. The virus can remain infectious in the air and on surfaces for up to two hours; leading to rapid spread.

Vaccination helps protect you and those around you

The CDC (Centers for Disease Control and Prevention) says that two doses of the MMR vaccine provide 97% protection against infection and one dose provides 93% protection. For adults who are not at high risk, one MMR vaccine is recommended. Two doses of the MMR vaccine are needed to protect against measles for most other people, including children, healthcare workers, college students, and household members of people with weakened immune systems.

Check out this CDC page for answers to many common questions about measles immunity and vaccination. Getting properly vaccinated doesn’t just protect you. It also protects those who cannot be vaccinated because they are less than 12 months old, allergic to the vaccine, or immune compromised.

More measles cases across the United States are expected soon. If you have any questions about getting vaccinated or whether you are already considered immune to measles, contact your healthcare provider. Please make sure you and your family are vaccinated. It’s the best way to be protected from this potentially deadly disease.
