Should I check my MMR vaccine antibody levels?

Hello, doctor.
I will be traveling to Manila for about three days at the end of June this year.
I know that there have been recent cases of measles in the Philippines.
I received the MMR vaccine in 2000 and again in March 2004.
How long does the immunity from the vaccine last? I am concerned about the risk of contracting measles; should I check my MMR antibody levels? Also, should I obtain medication for malaria prevention?

Dear Ms.
N:
Since you received one dose of the MMR vaccine in 2000 and another in March 2004 (as per government policy at one year of age and before entering elementary school), these two doses are expected to provide protection for approximately fifteen years or more, although the effectiveness may diminish over time.
Currently, the government recommends that women of childbearing age who do not have antibodies can receive one dose of the MMR vaccine at no cost.
Therefore, it is advisable for you to visit a family medicine department or a travel medicine clinic at any hospital to have your measles or rubella antibody levels tested.
If you have antibodies, you can be assured that you still have immunity.
If you do not have antibodies, you can receive the MMR vaccine at no cost.
For vaccination, you may inquire at travel medicine clinics or local health centers.

Sincerely,
Dr.

More Info

When considering travel to areas with reported outbreaks of diseases such as measles, it is prudent to assess your immunity status, especially if you have received the MMR (measles, mumps, and rubella) vaccine in the past. The MMR vaccine is known to provide long-lasting immunity, typically for at least 15 years, and often much longer. Given that you received the vaccine in 2000 and again in 2004, you likely still have a significant level of protection against measles. However, immunity can wane over time, and it is not uncommon for some individuals to experience a decrease in antibody levels after many years.

To determine your current immunity status, it is advisable to check your MMR antibody levels through a blood test. This test will measure the presence of antibodies against measles, mumps, and rubella in your bloodstream. If the test indicates that you have adequate levels of antibodies, you can travel with greater peace of mind, knowing that you are likely protected against measles. If the test shows insufficient antibody levels, you can receive a booster dose of the MMR vaccine, which is safe and can enhance your immunity before your trip.

In terms of your travel to Manila, it is also essential to consider the risk of malaria, especially if you plan to visit areas where the disease is endemic. Malaria is transmitted through the bites of infected mosquitoes, and the risk can vary depending on the specific location within the country. If you are traveling to regions where malaria is prevalent, it is recommended to take prophylactic medication to prevent infection. Common antimalarial medications include atovaquone-proguanil, doxycycline, and mefloquine, among others. It is best to consult with a healthcare provider or a travel medicine specialist to determine the most appropriate medication based on your travel itinerary, health status, and any potential drug interactions.

In summary, checking your MMR antibody levels before traveling is a wise decision, especially given the recent measles cases in the Philippines. If you find that your immunity is low, a booster shot can provide additional protection. Additionally, consider the risk of malaria in the areas you plan to visit and consult with a healthcare professional about the need for antimalarial medication. Taking these precautions can help ensure a safer and healthier travel experience.
