The Los Angeles County Department of Public Health (Public Health) is reminding residents get up-to-date on all recommended vaccines to minimize the chance of infection with contagious diseases.

Vaccines are the safest and most effective way to prevent diseases such as measles, rubella, pertussis, polio and hepatitis A or B, according to the department. People who plan to attend large-scale events or travel out of the country should take special precautions.

“Many vaccine-preventable diseases that are rare in the United States are still common in some parts of the world,” said Dr. Jeffrey Gunzenhauser, interim health officer for Los Angeles County. “Unvaccinated travelers to and from other regions can easily bring disease back to the U.S. This summer, before enjoying concerts, the Special Olympics World Games, or other large-scale events, make certain that you’re up-to-date with all recommended vaccines. This is the best way to guard against vaccine-preventable diseases.”

While planning international travel, residents should consult with their healthcare provider. Travel vaccines may be recommended based on the destination, length of stay and planned activities.
