Pfizer announced Wednesday that its COVID-19 vaccine is safe and strongly protective in kids as young as 12, a step toward possibly beginning shots in this age group before they head back to school in the fall.
Most COVID-19 vaccines being rolled out worldwide are for adults, who are at higher risk from the coronavirus. สล็อตเอ็กซ์โอ Pfizer’s vaccine is authorized for ages 16 and older. But vaccinating children of all ages will be critical to stopping the pandemic – and helping schools, at least the upper grades, start to look a little more normal after months of disruption.
In a study of 2,260 U.S. volunteers ages 12 to 15, preliminary data showed there were no cases of COVID-19 among fully vaccinated adolescents compared to 18 among those given dummy shots, Pfizer reported.
It’s a small study, that hasn’t yet been published, so another important piece of evidence is how well the shots revved up the kids’ immune systems. Researchers reported high levels of virus-fighting antibodies, somewhat higher than were seen in studies of young adults.
Kids had side effects similar to young adults, the company said. The main side effects are pain, fever, chills and fatigue, particularly after the second dose. The study will continue to track participants for two years for more information about long-term protection and safety.04/11/2021 at 9:44 PM #437325
Before writing homework in Canada https://ca.liuxuesavior.com/zuo-ye-dai-xie/, you must make a framework, and you must show the first two articles to your tutor. Ask if it can be written like this. To put it bluntly: Teacher, I am new to Australia and I have never done homework before. This is my first semester and also the first semester. Not sure if it can be written like this. I need help, and I guarantee 100% that no teacher will refuse your request. After you have confidence and experience, just don’t ask the teacher. Some topics seem big and difficult to write. But don’t worry. After you understand the topic, find something called a scoring guide. Generally speaking, if the topics are not connected, the teacher will give a separate grading standard. This standard is more important than the topic! Detailed written standards are needed to write out the content item by item.
