联合国发出警告：世界接种疫苗的孩子们数量下降得惊人。
The United Nations has warned of an "alarming" decrease in the number of children receiving life-saving vaccines² around the world.

 

The drop included vaccinations⁴ for preventable diseases such as diphtheria, tetanus and measles⁵, the U.N. said in a statement. The U.N.'s World Health Organization and UNICEF blame the decrease on the change in routine health care caused by the coronavirus crisis.

 

A vaccine¹ is a biological preparation that provides active immunity⁶ to an infectious disease. A vaccine usually contains a substance that is similar to the disease-causing illness. It tells the body's immune system to recognize the substance as a threat and destroy it.

 

"Vaccines are one of the most powerful tools in the history of public health, and more children are now being immunized than ever before," WHO chief Dr. Tedros Adhanom Ghebreyesus said in a statement.

 

"But the pandemic has put those gains at risk. The avoidable suffering and death caused by children missing out on routine immunizations could be far greater than COVID-19 itself."

 

The WHO and UNICEF said that even when vaccines are available, many children who need them are afraid to leave their homes because of the coronavirus. Others face difficulties traveling because of COVID-19 restrictions⁸.

 

But even before the spread of the coronavirus, the agencies said child vaccinations were already falling. They said nearly 14 million children did not get vaccinated⁹ against measles and pertussis in 2019. Most of these children live in Africa. Economic difficulties also prevented children in Brazil, India, Indonesia, Mexico, Pakistan and the Philippines from getting the needed vaccine.

 

COVID-19 has made routine vaccinations a major "challenge," UNICEF Executive Director Henrietta Fore⁷ said. She said vaccination³ programs need to be restarted urgently "before children's lives are threatened by other diseases. We cannot trade one health crisis for another."

 

The WHO says that before the spread of the coronavirus, more than 116 million, or 86 percent, of all babies born had been vaccinated every year for the past 10 years.

 

More than 20 life-threatening diseases can now be prevented by immunization, the WHO reports. In addition, new vaccines for major killers¹⁰ like diarrhea, cervical cancer, cholera¹¹ and meningitis are being introduced in several countries, the agency said.
