Pfizer In addition, BioNTech’s Covid-19 vaccine is safe and effective, showing a strong antibody response between the ages of 12 and 15. Both companies said last week that they paved the way for US and European approval to use shots from this age group. several weeks.

Data from clinical trials that put shots ahead of other Western vaccine developers to protect children will enable use in that group before the next grade, Pfizer CEO Albert Bourla said in a statement.

Whether the Covid-19 vaccine works and is safe for children is one of the major questions that pharmaceutical companies are trying to answer. Inoculation of children and adolescents is seen as an important step in reaching “herd immunity”, killing more than 2.9 million people and controlling the pandemic that infects 128.3 million people.

Dr. Assonshon Mejias, a pediatrician at the National Children’s Hospital in Columbus, Ohio, said:

Young people are less likely to get serious illness, are more likely to get asymptomatic infections, and can unknowingly infect others with Covid-19.

“Asymptomatic spread is your number one concern,” said Onisis Stefas, chief pharmacy officer at Northwell Health, a New York-based hospital system. “They are the most spreadable people.”

The· Pfizer/ BioNTech Two-shot Vaccine has already been approved for use in people up to the age of 16. The new study provides first evidence of how well it works in school-age adolescents.

In a study of 2,260 adolescents aged 12 to 15 years, there were 18 cases of Covid-19 in the placebo-vaccinated group and none of the actual vaccinated people, so 100 for disease prevention. There was a% effect. statement.

The vaccine was well tolerated and the side effects were consistent with those seen in participants aged 16-25 years in the adult trial. Both companies do not list the side effects of the latest release. In adult studies, side effects were generally mild to moderate, including pain at the injection site, headache, fever, and malaise.

The two companies also investigated a subset of teens to measure levels of virus-neutralizing antibodies produced one month after the second dose, a 16-25 year-old study of an important adult study. I found it comparable to the participants.

Bula said Pfizer “In the coming weeks, and … in the hope that other regulators around the world will begin vaccination of this age group before the start of the next school year,” the US Food and Drug Administration. We are planning to request the expansion of emergency use permission from.

Shortly after the data was released, Israel, the world leader in vaccination deployments, said it would begin giving shots to adolescents if the FDA gave it a green light.

More data

Scientists welcomed news that wasn’t published in medical journals or peer review, but said more data was needed.

Immunization of young people is important to achieve herd immunity, said Dr. Peter English, a former consultant for infectious disease management and a former chairman of the British Medical Association’s Public Health Commission. Stated.

Last week, the two companies gave their first vaccination in a series of trials testing it in younger children, including 6-month-old children.

Rivals are also testing their shots on young people.

This month, Moderna Inc began testing the Covid-19 vaccine in children aged 6 months to under 12 years.Johnson & Johnson, which recently received adult vaccine approval, has not yet begun Planned exams for children..

In December, AstraZeneca excluded children from mid- to late-stage trials of the COVID-19 vaccine in the United Kingdom.

Vaccines from British pharmaceutical companies have been associated with a very rare form of blood clotting in the brain this year, and some European countries are young adults, even though the cause of the condition remains unknown. We are urging you to stop using it.

In January, US infectious disease expert Dr. Anthony Fauci forecasted a US children’s vaccination campaign by late spring or early summer.
