Covid-19 (COVID-19) is an acronym for Coronavirus Disease 2019, “CO” stands for Corona, “VI” stands for Virus, “D” stands for Disease, and “19” is the year that the disease was first identified.

What approaches/platforms are mainly involved in producing COVID-19 vaccines?

There are three main approaches/platforms used in the production of COVID-19 vaccines that increase immunity against the disease without harming the body.

(1) The whole-microbe approach, in which a whole virus is contained in the vaccine

  • A live-attenuated vaccine uses a living but weakened version of the virus, or one that’s very similar

  • An inactivated vaccine uses inactivated or “killed” virus

    • For example: Sinovac, Sinopharm, and Covaxin COVID-19 vaccines

  • A viral vector vaccine uses a safe virus to deliver specific proteins of the virus of interest into the body

    • For example: AstraZeneca/Covishield, Janssen (Johnson & Johnson), and Sputnik COVID-19 vaccines

(2) The subunit approach, which uses the very specific proteins of a virus that the immune system can recognize, remember, and fight off

  • For example: Novavax/Covovax COVID-19 vaccine

(3) The genetic approach (nucleic acid vaccine) uses a section of the virus’ genetic material

An mRNA vaccine is a type of nucleic acid vaccine developed using a genetic molecule of the virus called messenger RNA that stimulates the body's immune system

  • For Example: Pfizer and Moderna COVID-19 vaccines

What type of vaccine is the Sinovac COVID-19 vaccine?

The Sinovac COVID-19 vaccine is an inactivated vaccine containing viruses that can no longer multiply or cause harm to the human body. It stimulates the body's immune system to produce antibodies.The Sinovac COVID-19 vaccine is one of the least likely COVID-19 vaccines to cause side effects after the injection.

You can receive your COVID-19 vaccine one month after developing symptoms of COVID-19.
