Why do kids not get hardly any immunity to strep throat? are there too many different strains?

No One Knows: A good question! at present there is no understanding as to why certain infections trigger life long immunity such as chicken pox and some do not such as strep throat.

Its the germ: In general, you can develop strong immunity to viruses that tend to involve your whole body and trigger the response of your whole immune system (measles).Bacteria cause localized infections and the immune response if any is temporary.(strep) you can get the same strain of strep repeatedly within the same year.
