Measles: Are your vaccines up to date?

Measles is a very contagious viral disease that is widespread in many parts of the world. Travelers can bring measles into the United States from any country where measles outbreaks are occurring.

Fortunately, measles vaccine is highly effective at preventing the disease and has been routinely recommended in the United States for many years. 97 percent of people who receive two doses of measles vaccine develop lifelong immunity to measles. People who have not been vaccinated are highly likely to get measles if they are exposed to the disease.

Typically, children in the United States get their first dose of measles vaccine beginning at 12 months of age followed by a second dose between ages 4 and 6 years. Make sure that you and your family are up to date on measles vaccine, especially before international travel. Infants aged 6-11 months should receive one early dose of measles vaccine (called MMR) before international travel.

Pregnant? Get Vaccinated to Protect Your Baby from Pertussis

Pertussis (Whooping Cough) is an easily spread infectious disease. It can cause coughing fits that make it hard to breathe. Young babies can get very sick, very fast if they get pertussis. Vaccination is the best way to prevent pertussis. The pertussis vaccine for adolescents and adults is called Tdap.
