The hepatitis A vaccine, the rubella portion of the MMR vaccine, the chicken pox vaccine, and the shingles vaccine all contain viruses (weakened or inactivated) that were grown in human cells. A virus must be given a medium in which to propagate.
Chara (typically /ËkÃ¦.É¹Ê/ or /ËtÊÉË.É¹Ê/), also known as the First Human or the Fallen Human, is the first human to fall into the Underground. This is the human that the player names at the start of the game, and not the controllable character who is played throughout the entirety of Undertale.
Chara is said to have looked incredibly similar to Frisk, down to a similar fashion sense.. They are of ambiguous gender and appear to have also been around the same age as Frisk when they fell into the Underground. Two promotional gameplay screenshots have 'Chara' as the name. 2  Other materials leave the name blank. 3  Whether a coincidence or some other reason, Chara's soul is the same color as Frisk's, which can be seen on the empty coffin in the room down the hall from the throne room.
