Read the following passage about The Vaccine and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30.

The vaccine is one of the most important inventions in human history. It has saved millions of lives and changed the course of public health. The first successful vaccine was developed by Edward Jenner in 1796, when he discovered that injecting people with cowpox could protect them from smallpox. This breakthrough laid the foundation for the development of vaccines against other deadly diseases.

Vaccines work by stimulating the body's immune system to recognize and fight specific pathogens. When a person is vaccinated, they are exposed to a small, harmless part of the virus or bacteria. This teaches the immune system to recognize the disease and prepare to fight it if exposed in the future. Over time, vaccines have successfully eradicated diseases like smallpox and have brought others, such as polio and measles, to the brink of elimination.

Despite their success, vaccines have faced resistance. Misinformation, fear, and distrust have led some people to question their safety and effectiveness. However, the overwhelming scientific evidence supports the fact that vaccines are one of the safest and most effective ways to prevent disease. Vaccination has not only saved lives but also reduced the burden on healthcare systems worldwide.

As new diseases emerge, the importance of vaccines continues to grow. With the rapid development of COVID-19 vaccines, humanity has shown its ability to adapt and fight new threats. The vaccine remains a symbol of scientific progress, offering hope for a healthier future.
