COVID-19 vaccination for children under 12 may be approved at 2021 end

COVID-19 vaccination for children under 12 may be approved at 2021 end.  More than 90,000 children in the United States were infected with COVID-19 in a week, and the COVID-19 vaccination for children under 12 years old may be approved at the end of the year or early next year. 

Affected by the delta COVID-19 mutant virus, the United States has ushered in a new peak of the epidemic, and children are not immune. US CDC data show that from August 2 to 9 there were 94,000 new cases of childhood infections, of which 239 were hospitalized patients, an increase of 30% from the previous week.

Affected by this, many parts of the United States fell into chaos at the beginning of the new school year. A child from Reno School in Nevada tested positive for COVID-19 and more than 80 students were quarantined; Palm Beach County, Florida, had positive cases in the first two days of the new school year; Mississippi Department of Health data showed that from July 26 to August 2 Approximately 4,400 students were quarantined within one week of Japan…

US CDC Director Rochelle Walensky said that the current incidence of COVID-19 in children is slightly lower than that of adults. As the Delta virus epidemic continues, this data will continue to change. After children have been infected with the new coronavirus for a long time, the most common symptoms are fatigue and headache. They may also have long-term symptoms such as dizziness, cognitive impairment that cause academic difficulties, and poor mood. I don’t know how long it will take to recover.

Dr. Bud Weidermann of Coldrun National Hospital in the United States is in charge of children’s vaccine trials. There are currently more than 2,000 children waiting to participate. The United States has not yet opened up vaccination to children under 12 years old, and more and more parents, doctors, and government officials are expressing great concern about the immunization of children.

The US FDA has stricter approval requirements for vaccines for children than for adults. The FDA requires researchers to provide safety data for adult vaccinators for two months, while children need six months. At the same time, the FDA last month also asked Pfizer and Moderna to double the number of participants in children’s vaccine trials. The American Academy of Pediatrics questioned this, saying that children’s needs for the COVID-19 vaccine are very urgent. We understand the six-month safety data requirements, but a longer clinical trial cycle will mean that more children will be infected with the highly contagious Delta virus.

According to current research progress, Pfizer said that it will announce the COVID-19 vaccination data for children aged 5-11 in September, and will provide data for younger age groups thereafter, and apply for emergency use authorization; Johnson & Johnson has launched a vaccine for children aged 16 and 17 The trial will also start four lower-age trials this fall. Experts believe that the COVID-19 vaccine for children may be on the market at the end of this year or early next year.

At the same time, researchers from the Mayo Clinic sent another not-so-optimistic news: Mayo Clinic and Nference Biotechnology released a retrospective study on the preprint website medrxiv, which stated that Pfizer vaccine is effective against the COVID-19 caused by delta virus infection.

The effective rate of prevention of pneumonia and hospitalization was 76% and 85%, but the effectiveness of prevention of its infection was only 42%, and the effectiveness of Moderna was also reduced to 76%. The research results have not passed peer review and need further review.

At the same time, in response to the mutated virus infection and the reduced effectiveness of the vaccine, the FDA has urgently approved the third dose of vaccine for immune-compromised people.

Dr. Peter Hotez, Dean of the National School of Tropical Medicine at Baylor College of Medicine, said that vaccination is the most ideal preventive measure for children, but young children cannot be vaccinated at present. To protect them from infection, every adult should do it Get vaccinated and take preventive measures such as wearing a mask.

At the same time, children must maintain social distance, good ventilation, hand hygiene and wear masks when they return to school. Although wearing a mask may reduce some facial expression information and may have a certain impact on children’s learning and cognitive ability, it is better to wear a mask than the potential risk of infection.Children’s learning adaptability is very strong. In the normalized environment of masks, children still have various ways of communication.
