Vaccination is one of the most effective ways to protect people from dangerous diseases. Vaccines prepare our body’s immune system to fight infections without making us seriously ill. They have helped the world control or even eliminate deadly diseases like smallpox, polio, and measles.

The importance of vaccination is not only personal but also social. When most people in a community are vaccinated, the spread of disease becomes very low, which protects even those who cannot take vaccines due to health reasons. This is called herd immunity.

In today’s world, with the risk of new viruses and global travel, vaccines are more important than ever. They save millions of lives each year, reduce healthcare costs, and keep societies healthy. Everyone should follow the recommended vaccination schedule for children and adults to stay safe and protect others.
