Think of virus like a bag–a bag filled with genetic material. Pretend that the bag, a circular bag, is the envelop of a virus. Inside the bag, or the virus’s envelop, you can find either DNA or RNA (i.e. the genetic information of the virus).
SARS-CoV-2 is the kind of bag that contains RNA, not DNA. In fact, the SARS-CoV-2 bag only contains a long strand of RNA. The “bag” or the envelop of SARS-CoV-2, like many other viruses, is made of lipid bilayers, i.e. fatty acids chains organized in two layers. (See Figure 1 below)

Figure 1: The image of the infamous SARS-CoV-2, taken using transmission electron microscope (TEM). (Photo: GEN) The diameter of the virus is around 120 nm (Britannica, accessed March 21, 2020). As a comparison, imagine lining these guys up in a straight line, all 1,000,000 of them, and you will get 1 mm!

Vaccines are a hot topic in the recent years. Many have strong opinions about it. Yes, we are entitled to our points of view but when it comes to making decisions that will impact the entire population, we have to take full responsibility to make educated, informed decisions.
Vaccines today are quite sophisticated, but it came from a crude beginning.
