CLA의 피츠버그 소식

Covid-19 백신 4가지 종류

4/12/2021

현재 개발되고 있는 코로나 바이러스 백신 4가지 종류에 대한 간략한 설명이 cnn 기사에 있어서 가져왔습니다. 생각보다 뉴스를 안보는 학생들이 많습니다. 현재 세계에 어떤 일이 일어나고 있는지에 대해서는 늘 관심을 가지고 있어야 합니다. 시험에 현재 이슈가 곧잘 등장하기도 하지만 뭐든 알고 있으면 변화하는 세상에 적응하고 대처하기 쉽습니다.

mRNA VACCINE
Used by: Pfizer, Moderna
Doses: 2
mRNA vaccines are the newest approach. They use genetic material called messenger RNA, a kind of genetic software that instructs cells to make a piece of the coronavirus spike protein. That will get the attention of the immune system. They coated the mRNA in soft fatty lipids to protect it.

VECTOR VACCINES
Used by: AstraZeneca, Janssen, Sputnik
Doses: 1-2
Vector vaccines use another virus to carry in the genetic instructions to make the spike protein. For coronavirus they all use adenoviruses, a type of common cold virus. They attach to cells and inject DNA that tells the cells to make coronavirus spike protein.

PROTEIN SUBUNIT VACCINE
Used by: Novavax, Sanofi
Doses: 1-2
Protein subunit vaccines just get little pieces of the target virus circulating in the system for the immune system to find and recognize. Instead of using the human body as the vaccine factory, genetically engineered insect viruses are used to infect moths, whose cells then produce the pieces of coronavirus spike protein. These are harvested and made into a vaccine.

WHOLE, KILLED VACCINES
Used by: Sinovac
Doses: 1
Whole inactivated virus vaccines take longer to make because batches of the coronavirus must first be grown and then killed using a chemical or heat, and then made into a vaccine that can be injected to elicit an immune reponse.
