Two shots of the Pfizer-BioNTech COVID-19 vaccine were less effective in reducing the risk of various forms of Omicron in young children than in older groups, according to new data released this week by the Centers for Disease Control and Prevention. According to.
Statistics released by the CDC at the end of Thursday COVID-NET Hospital Supervision As of the end of January, vaccinated Americans of any age had lower COVID-19 hospital admissions than non-vaccinated people.
However, the smallest difference was in children aged 5 to 17 years. The hospital admission rate was six times higher than that of unvaccinated adults. The rate was three times higher among children aged 5 to 11 years and twice as high among children aged 12 to 17 years.
CDC too Published a new study In its weekly report on morbidity and mortality on Friday, it is estimated that two shots of the Pfizer vaccine were 31% effective against various types of Omicron infections in children aged 5 to 11 years.
The effectiveness of the vaccine against Omicron was practically doubled in adolescents between the ages of 12 and 15, at 59%, although the study authors noted that there was “widespread and overlapping” statistical uncertainty around the two figures. The situation suggests that they “may not be significantly different.”
Researchers regularly tested enrolled children in four states – Arizona, Florida, Texas and Utah – starting July 2021. During the dominance of the Delta variant, research found that the effectiveness of vaccines against infections in adolescents was 87%.
“The study of the effectiveness of other pediatric vaccines relies on laboratory testing data or health records and usually only catches cases where the child has symptoms and is receiving health care. Infection and the effectiveness of the vaccine, “Investigators are the co-authors of this study,” Principal Investigator Lauren Olsho said in a release to Abt Associates.
In the study population, vaccinated children who caught COVID spent an average of half a day less sick than non-vaccinated children. However, the study authors also noted that both groups reported different behaviors: Vaccinated children were more likely to be wearing face masks and to be absent from school for longer periods of time when ill.

An increasing number of studies have shown that vaccine efficacy has decreased in people who have not taken a booster shot during the Omekron period..
Pfizer and BioNTech have stated that they expect to receive data from their trials. Early next month Which could allow regulators to greenlight third foods for children.
In a statement, the CDC said the agency “continues to recommend COVID-19 vaccination as a safe and important tool to protect children and adolescents regardless of their health status.”
There are children between the ages of 5 and 17. Generally less likely Admission to hospital with COVID-19 than adults, Hundreds of children have died The disease and many people have suffered serious complications from COVID-19.
CDC Recently said Parents can take the first two shots of their children up to eight weeks as a way to potentially increase the effectiveness of the vaccine and reduce the risk of side effects associated with the rare vaccine associated with the vaccine.
A separate the study A joint study by CDC scientists released Friday – posted as a pre-print that has not yet been peer-reviewed – found that overall in children during COVID-19 Hospitalization rates were higher than the previous flu season, even before the record Omicron surge A record increase In children’s hospitals
However, the Biden administration has so far struggled to persuade many parents to vaccinate their youngest eligible children, with an initial rollout. Left behind by old age..
Only 26.6% of children aged 5 to 11 years Are fully vaccinated.
By the end of January, a Ongoing CDC survey The share of parents was found that they would “probably or certainly” not vaccinate their 5 to 11 year old child, which had reached 31%.
“The data show that the vaccine is one of the most effective ways to protect people, including children, from serious illness, hospitalization and death by preventing COVID-19,” said Dr. Nero Shah, of Maine. Senior health officials and the president of the association, state and regional health officials Said last week.
Shah’s statement came after a controversy erupted by a Florida surgeon general.Vaccinate children against COVID-19.
“Now is the time to help as many families and communities as possible protect themselves through vaccination,” Shah said.
