How many types of COVID-19 vaccines are there? Vaccines against COVID-19 can be divided into 4 main types according to the method of production.
- mRNA vaccines
mRNA vaccines are the production of vaccines using part of the genetic code of the virus injected into the body. like the COVID-19 vaccine Using the genetic material of the SARS-CoV-2 virus (SARS-CoV-2) when injected into the body. The vaccine will stimulate the body to build immunity to prevent this virus from coming up. mRNA -based COVID- 19 vaccines such as Pfizer-Biontech and Moderna.
- Viral vector vaccines
Viral vector vaccines are the production of vaccines by genetic editing that weakens the virus. It does not cause disease. When injected into the body, the virus will not cause disease. But will stimulate the body to build up immunity instead. A viral vector for COVID- 19 vaccines such as Oxford-AstraZeneca.
- Protein-based vaccines
Protein-based vaccines are the production of vaccines by injecting part of the proteins of the virus. Such as spike proteins. Then stimulate the body to build immunity against the COVID-19 virus.
- Inactivated vaccines
Inactivated vaccines are vaccines produced by injecting a lethal virus into the body. Then stimulate the body to build immunity Inactivated COVID-19 vaccines such as Sinovac and Sinopharm.
