Why World Immunization Week Vaccinations Are Beneficial

Xinhua News Agency, Beijing, April 24 (Reporter Feng Yujing) This year's World Immunization Week is from April 24 to 30, with the theme of "everyone live a long life".

The World Health Organization said in this year's World Immunization Week-related materials that since the first smallpox vaccine was developed in 1796, hundreds of vaccines have been developed and billions of people's lives have been extended

According to WHO data, vaccines have so far prevented more than 20 life-threatening diseases, helping people of all ages live longer and healthier lives

Vaccination is a simple, safe and effective way to protect people from harmful diseases before they are exposed to them, by training a person's immune system to produce antibodies, the WHO said

When vaccinated, a person's immune system responds by recognizing invading viruses or bacteria; producing antibodies, proteins that the immune system naturally produces to fight disease; and remembering the disease and how to fight it

But without a vaccine, humans are at risk of severe illness and disability from diseases such as measles, meningitis and tetanus

At present, in the process of responding to the new crown epidemic, vaccination against the new crown virus has also been proved to be effective in preventing severe disease and death caused by the new crown virus
