How many types of COVID-19 vaccine are there?
Dr. Somchai Leelasiriwong, Risk Manager Advisor Praram 9 Hospital states that the vaccine used to prevent Covid-19 Currently, there are four main types, divided from techniques used in the production of COVID-19 vaccines:

mRNA vaccines or genetic vaccines It is a new technology that has been used in the development of Ebola vaccines. This vaccine uses the genetic material of COVID-19. SARS-CoV-2, or SARS-CoV-2, directs the production of spike protein and makes the body immune to COVID-19.

mRNA Vaccines: BioNTech/Pfizer and Moderna
Viral vector vaccines or virus-borne vaccines Developed by introducing a weakened virus or unable to divide to be genetically modified for use as a vector Then deposit the genetic material of COVID-19 into the body to make the immune system up. This technique is a method that can stimulate the immune system well. Because it mimics an infection that is close to nature.

Viral vector vaccines: Johnson & Johnson, Sputnik V and Oxford – AstraZeneca

Protein-based vaccines, or vaccines made from proteins in part of the virus SARS-CoV-2 (SARS-CoV-2) by taking some proteins of COVID-19, such as spiny proteins. mixed with stimulants before injecting into the body and then mixed with stimulants When injected, it will stimulate the body to build immunity against the virus. been used for a long time Because it is a technique used to produce influenza vaccines. and hepatitis B vaccine

Protein-based vaccine: Novavax
Inactivated vaccines or inactivated vaccines It is produced from the introduction of COVID-19. to kill with chemicals or heat before injecting into the body to stimulate immunity against the virus This technique is relatively slow and costly as it must be manufactured in a Level 3 safety laboratory.
