Do adults need a measles booster? An epidemiologist explains who is immune - PBS

Understanding Immunity to Measles

Measles is a highly contagious viral infection that can lead to serious complications, especially in young children. Immunity to measles can be acquired through either vaccination or previous infection. However, immunity from vaccination may wane over time, leading some adults to wonder if they need a booster shot.

Medical epidemiologists recommend that adults born before 1957 are likely immune to measles due to previous exposure to the virus. For those born after 1957, immunity may vary depending on vaccination history and exposure to the virus. It's important to consult with a healthcare provider to determine individual immunity status.

Checking antibody levels through blood tests can also help assess immunity to measles. These tests can measure the presence of measles-specific antibodies, indicating whether a person is protected against the virus or may need a booster shot to enhance immunity.

While most adults who received the measles vaccine as children are likely immune, there are certain groups who may benefit from a booster shot. This includes healthcare workers, international travelers, and individuals with compromised immune systems.

Healthcare workers, in particular, are at a higher risk of exposure to measles due to their close contact with patients. Therefore, it is often recommended for them to receive a booster to ensure continued protection.

For international travelers, getting a booster shot may be advisable, especially if they are visiting countries where measles is still prevalent. This extra precaution can help prevent the spread of the virus to areas with lower vaccination rates.

According to Dr. Johnson, a medical epidemiologist at the CDC, "Adults who received their last measles vaccine before 1968 or who are unsure of their vaccination status should strongly consider getting a booster shot." This is especially important in light of the recent measles outbreaks across the country.

As cases of measles continue to increase, it is important for adults to consider whether they are immune to the virus. While most individuals who received the measles vaccine as children are likely protected, some may benefit from a booster shot. Consulting with a healthcare provider and checking antibody levels can help determine the best course of action for maintaining immunity and preventing the spread of this highly contagious disease.

Ultimately, staying informed and proactive about vaccination can help protect not only individuals but also the community at large from the resurgence of preventable diseases like measles.

With the guidance of medical professionals and a commitment to public health, we can work together to ensure that outbreaks of measles become a thing of the past.
