Immunization is a fundamental public health strategy that involves administering vaccines to individuals to protect them against infectious diseases. By stimulating the body’s immune system to recognize and combat pathogens, vaccines have significantly reduced the prevalence of diseases such as measles, polio, and diphtheria.
Global Impact of Immunization
Since the establishment of the Expanded Programme on Immunization (EPI) in 1974, vaccination has prevented 154 million deaths, with 146 million of these in children under five years old. Measles vaccination alone has prevented 93.7 million deaths globally.
Current Challenges
Despite these successes, recent years have seen a resurgence of vaccine-preventable diseases. In the United States, measles outbreaks have increased, prompting health experts to urge individuals to ensure their vaccinations are up-to-date. The CDC recommends that children receive two doses of the MMR vaccine, with the first at 12-15 months and the second at 4-6 years old. Adults without prior vaccinations or immunity should also get vaccinated.
In Texas, the Department of State Health Services canceled its biennial immunization conference due to uncertainty regarding the participation of personnel from the U.S. Centers for Disease Control and Prevention (CDC). This uncertainty arises from a temporary communication pause imposed by the Trump administration on federal health agencies such as the CDC.
Immunization in India
In India, immunization is a critical component of public health strategy. The government has implemented the Universal Immunization Programme (UIP), aiming to provide free vaccines to all children under the age of two. This initiative targets diseases such as tuberculosis, polio, diphtheria, pertussis, tetanus, hepatitis B, and measles. The UIP has significantly contributed to reducing child mortality rates and improving overall public health in the country.
Conclusion
Immunization remains a vital tool in preventing infectious diseases and promoting public health. Ongoing efforts are necessary to address challenges such as vaccine hesitancy, logistical barriers, and misinformation to maintain and enhance the effectiveness of immunization programs worldwide.
