Covid-19 vaccine In the world right now, there are many types and brands. It depends on how it is produced. pg Which country produces which one? will use that injected to the population in that country supplemented with additional vaccines received from foreign countries for families per the population of that country

Recently, Thailand received the Covid-19 vaccine. already a number and gradually ordering imported from abroad There is also a vaccine produced in our own country that is in the process of production for Thai people to use themselves in the country at a lower price as well.

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 part of the protein 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.

Inactivated (inactivated) vaccines: Sinopharm and Sinovac.
