Why there is no vaccine for Roseola?

[Guest guest]

I have a question that maybe someone can answer. Roseola is pretty

common among kids. It was the first " disease " my son had at about 1.3

years old. High fever really scarred me but he was surprisingly

unaffected (good mood/appetite).

My question is, why didn't pharma come up with a vaccine against

Roseola yet? It's seems to be pretty common and with the scarry high

fever and rush afterwards, it would be pretty good business for them. I

can see people vaccinating their infants for it. Just a thought i've

been carrying in my head.
