According to a new report from the United States Centers for Disease Control and Control, the release rates of vaccines at kindergartens in the United States have increased slightly. shows that the rate of infants who do not receive vaccines against certain diseases, including measles, has continued to increase in recent years. For the 2018/19 school year, the national percentage of kindergarten teachers with an exemption of one or more required vaccines was 2.5%, which corresponds to an increase. The report showed a slight increase of 2.3% in the previous school year and 2.1% in the previous year School year 2016/17. The percentage of kindergarten teachers with a waiver of one or more required vaccines ranged from 0.1
According to a new report from the United States Centers for Disease Control and Control, infant vaccine exemptions have risen slightly in the United States.
The findings were published in the CDC's weekly report on morbidity and mortality on Thursday. It shows that the infant rate, which has not been vaccinated against certain diseases, including measles, has continued to increase in recent years.
For the 2018-19 school year, the national percentage of kindergarten teachers required with one exception of one or more vaccines was 2.5%, a slight increase over 2.3% in the previous school year and 2.1% in the 2016 school year / 17 corresponds.
The percentage of kindergarten teachers except one or more required vaccines was in the range The report found that between 0.1% in Mississippi and 7.7% in Idaho and Oregon.
Of these vaccine-free kindergarten teachers, only 0.3% had a medical exemption, while 2.2% had no medical exemption. According to the report, there was a derogation.
"Measles outbreaks affecting school-age children in several states during the 2018-19 school year underline the importance of both school vaccination requirements for preventing the spread of disease and assessing school coverage to identify vaccine herds" the researchers in the report.
These recent measles outbreaks occurred despite US measles virus being eliminated in 2000, meaning that the disease was not transmitted continuously for more than a year. Measles can be prevented with the measles, mumps and rubella vaccine.
"Although the overall proportion of children with a second-year exemption rose slightly, children with exemptions still account for a small proportion of nursery students from national and most states," the researchers wrote. "More importantly, in 25 states, the number of under-vaccinated kindergarten teachers who were not exempted exceeded the number of children with exceptions."

The report found that students who are provisionally enrolled within a grace period or otherwise are not Have proof of vaccination, are excluded from participation. A period of grace refers to a specified number of days on which a student can enroll and attend school without proof of full vaccination or exemption. Preliminary enrollment allows a student without full vaccination or exemption to attend school while he / she is carrying out a recovery plan. In many states, under-vaccinated students who have not been excluded go to school for a period of grace or are enrolled for the time being.
States with the lowest and highest vaccination rates
The new report summarized the data on the vaccination coverage of about 3.6 million kindergartens during the school year, the school year 2018-19. The data was collected by state and local vaccination programs in 49 states: all states except Alaska, for which data was not provided to the CDC.
The report also included data on the vaccine-free vaccination of approximately 3.6 million kindergarten teachers in all 50 states.  Federally-funded immunization programs work with education ministries, school nurses and other school staff to assess the vaccination coverage and exemption status of children enrolled in public and private nursery schools and then report the data to the CDC.
The New Report noted this In the 2018/19 school year, the countrywide child-child vaccination coverage for the dual MMR vaccine ranged from 87.4% in Colorado to at least 99.2% in Mississippi.
The recommended vaccination coverage for MMR is reported to be at least 95% on the report.
For the diphtheria and tetanus toxoid (DTaP) vaccine, coverage was between 88.8% in Idaho and at least 99.2% in Mississippi rding to the report.
For the varicella or chickenpox vaccine, the report found coverage between 86.5% in Colorado and at least 99.2% in Mississippi.
National for the 2018-19 school year, the coverage among kindergarten teachers for these vaccines was 94.7% for two doses of MMR; 94.9% for the required doses of DTaP; and 94.8% for the varicella vaccine, according to the report.
The report has some limitations, including the fact that the data is based on school records, so some children may not be included in the data, eg. For example, those who are home-schooled.
Direct comparisons of regions or states require further investigation, as comparability in the new report is limited due to differing state requirements, data collection methods and definition of grace periods or provisional vaccine registration requirements.
"Today's data confirms that childhood vaccine coverage remains high," said Ranee Seither of CDC's Immunization Services Division and lead author of the report in a Thursday email.
"Most parents continue to protect their children from 14 vaccine-preventable diseases, and although the countrywide coverage is high and even high in many states, there are still inadequately vaccinated communities," Seither said.
& # 39; Clu While the CDC regularly reports on nationwide vaccination exemptions, the agency could better predict potential measles outbreaks – or outbreaks of other infections – resulting from declining vaccine coverage by also examining the vaccine exemptions local level, for example by county or school, said Peter Hotez, Dean of the National School of Tropical Medicine at Baylor College of Medicine in Houston and co-director of the Texas Children's Hospital Development Center for Vaccines, was not involved in the new report.
Hotez and his colleagues carried out their own study in the United States of exemptions for non-medical vaccines at the county level, published last year in Plos Medicine.
In more than half of the 18 states where such policies were possible at the time, philosophy-based exceptions to vaccines had increased between 2009 and 2017: Arizona, Idaho, Maine, Minnesota, North Dakota, Ohio, Oklahoma , Oregon, Texas and Utah.
Overall, this earlier study found that "at least 100 counties, including 14 urban counties, are highly susceptible to measles," Hotez said.
"Measles broke out in seven of these 14 districts, so we made the first good measles prediction map," he said. "I would instead recommend that the CDC publish at least exemptions in addition to country or even school-level exemptions, and they should do so on an annual basis."
Other research published in the medical journal JAMA in 2016 showed that states with philosophical exceptions have both higher refusal rates and higher disease rates.
"Clusters of rejections overlap clusters of outbreaks," Saad B. Omer, professor of global health and epidemiology and paediatrics at Emory University, who led this separate research, told CNN last year.
"However, if it's difficult to get relief, you'll have lower rejection rates and lower disease rates," he said.
