A report released by the World Health Organization (WHO) this month shows that since the beginning of the new crown, the global vaccine vaccination has gone through the maximum decline in nearly 30 years.

According to "Nature", data collected by WHO and the United Nations Children's Foundation show that from 2019 to 2021, the proportion of children with three doses of white throat, tetanus and pertussis vaccines (pertussis closes) fell by 5 percentage points, globally, globally, and globally Fall to 81%. Bai Baipo Sanlian Vaccine is considered a sign of the vaccine coverage. If children miss these vaccines, they may also miss the key vaccination of many other diseases.

The report found that in 2021, the routine immune vaccination of 25 million children missed diseases such as measles, which led to an epidemic situation that could have been avoided. A Who spokesman said that if this decline continues, it is expected that the outbreak will be more controlled or died of cases.

From 2011 to 2019, the global vaccination coverage rate stagnated at about 85%. During the new crown epidemic, this ratio fell sharply in 2020 and 2021, especially in low -income and middle -income countries.

In 2021, among 18 million children who have never been vaccinated with Bai Bai Bai Sanlian Vaccine, the largest number was India, Nigeria, Indonesia, Ethiopia and the Philippines.

The coverage of vaccination in high -income countries has decreased slightly, from 95%in 2019 to 94%in 2021.

However, a WHO spokesman said, "Although the vaccine coverage rate has only declined slightly, the global vaccine can prevent the increase in disease cases, and it may also open the door for the epidemic to outbreak anywhere."

The backwardness of vaccine coverage has deviated the world from the orbit that achieves global immune targets. One of the immune targets will be reduced by 50%of the number of children who have not accepted any conventional vaccine by 2030. WHO data shows that nearly 25 million children did not take over the first dose of measles vaccine in 2021, which was 5 million more than in 2019.

From January to April 2022, there were nearly 50,000 cases of measles worldwide, which was more than twice that the number of cases reported from January to April 2021. In February and May, Malawi and Mozambique reported the wild spinal ash virus virus, which broke out for the first time in the past 30 years.

WHO and the United Nations Children's Foundation also found that the number of girls who vaccinated the Pupar Virus (HPV) vaccine have fallen sharply, and HPV can lead to cervical cancer.

According to WHO, some reasons for the decline in child immunization vaccination rates are that the new crowns have caused supply chain interruption, resource transfer and blockade. This limits immunization services, and economic challenges have also reduced the government's funding for conventional vaccination. In addition, other factors have also led to the increase in the number of people affected by conflicts or natural disasters.

It is worth mentioning that vaccination is expected to return to the right track, and many countries are implementing vaccination movements. For example, India has strengthened the "Dranda Nush task" to ensure that children and pregnant women who have not vaccinated and partial vaccine obtain conventional immunization services.

However, Giridhar Babu, an epidemiologist in the Indian Public Health Foundation, said that as countries hope to recover from the epidemic, related resources may be transferred from the health care department to other departments. "In the next few months, we should be committed to ensuring the vaccination movement, especially in countries with a high proportion of vaccines for children."
