What is one of the campaigns initiated under the policy guidance of the Ligtas Tigdas program?

One of the campaigns initiated under the policy guidance of the Ligtas Tigdas program is indeed Ligtas Tigdas itself. This program is focused on achieving high levels of vaccination coverage against measles, which is critical in preventing outbreaks and protecting public health. The program emphasizes the importance of immunization as a vital preventive measure in child healthcare. By creating awareness and mobilizing resources, Ligtas Tigdas aims to ensure that all children receive the measles vaccine, thereby enhancing herd immunity in the population. This campaign represents a direct response to controlling measles and safeguarding children's health, showcasing how targeted immunization efforts are pivotal in public health strategies.

The other options listed do not represent campaigns directly associated with Ligtas Tigdas. For instance, the Safe Water Program focuses on improving water access and quality, which, while crucial for health, is separate from the vaccination initiative. Similarly, the Nutrition Enhancement Program aims to address nutritional deficiencies, and the Clean Air Initiative deals with improving air quality. Each of these programs has its own objectives and is not directly part of the vaccination efforts embodied in the Ligtas Tigdas program.
