lt was said that the first Pfizer vaccine was given to 6 people in 1 vial (1 bottle).

After that, you can inoculate up to 7 people by using the Korean minimum residual syringe.

There was also a controversy that many people are aware of.

Let's talk about facts and hypotheses here.

However, according to the guidelines of the Centers for Disease Control and Prevention,
