Pfizer’s Covid vaccine and two-dose BioNTech Covid provided very little protection for children aged 5 to 11 during an omicron infection wave in New York, according to a study published Monday.
The New York State Department of Health has found that the effectiveness of Pfizer’s anti-Covid vaccine has dropped from 68% to 12% in children in that age group during omicron surgery from December 13 to Jan. 24. from 100% to 48% at the same time.
The study has not been reviewed by peers, the gold standard of education. Due to the urgency of the public health epidemic, scientists were publishing the results of their studies prior to such a review.
The team of public health officials who conducted the study said that the dramatic decline in vaccine use in children aged 5 to 11 may be due to the low dose they received. Children in this age group are given two 10-microgram images, while children ages 12 to 17 receive 30-microgram shots.
The researchers also compared 11- and 12-year-olds on the weekend of January 30. They found the vaccine effectiveness dropped to 11% in the low-dose group but provided 67% protection in the high-dose group.
“Given the rapid loss of immunity, these results highlight the continuing importance of horizontal protection, including the wearing of masks, in order to protect children from infection and infection,” public health officials wrote in the study.
For children aged 12 to 17, the effectiveness of the immunization vaccine dropped from 66% to 51% from December to the end of January. Sleep protection has dropped from 85% to 73% among young people over the same period.
The details come as New York City plans to end its school mask campaign on March 7, with California doing the same four days later. Regional governments are cutting back on powers and restrictions as Covid infection declines sharply after the omicron diversity swept the country in December and January.
Covid infections dropped by 91% from a major pandemic in January. The United States reported a daily rate of nearly 66,000 new infections on Sunday, compared with more than 802,000 in Jan. 15, according to a CNBC study of data from Johns Hopkins University.
The United States has been hit by a spike in Covid-based children’s hospitals during an omicron wave. The Food and Drug Administration wants to speed up the Pfizer vaccine for children aged six to four months this month by responding to the number of children hospitalized with Covid.
However, the FDA and Pfizer decided to suspend those plans after the first two dosage data did not meet expectations. The FDA is now waiting to see clinical trial data for a third dose of young infants, expected in April.
