Although the character must survive entirely on energy shield instead of life, immunity to chaos damage can be a significant advantage.
The chance and duration of both being stunned and receiving an elemental status ailments is based on your base life before CI takes effect. Maximum Life modifiers such as increased maximum Life, reduced maximum Life, etc. apply to the life before CI is applied. Since this base life value is then overwritten by CI, the only advantage life modifiers provide to a CI character is the reduction on stun and status ailment.

Chaos resistance reduction/penetration
It is generally best to wait until you have high energy shield before taking CI because it's much easier to survive on life at lower levels. Don't be afraid to take life passive skills for survivability while leveling up, since you can remove them later.
Characters with CI are usually more susceptible to stun and status ailments because of their low base life. Rather than taking otherwise useless life nodes as described above, Stun can be mitigated by increasing the Stun Recovery stat with items and passives or unique items such as Eye of ChayulaEye of Chayula

Chaos Inoculation works well with some other keystone passives, such as:
- Ghost Reaver converts life gained from life leech into energy shield. Vaal Pact only disables any regeneration granted from passives that's converted by Zealot's Oath as of 3.0.0
- Zealot's Oath applies life regeneration to energy shield. Regen effects that are based on maximum life become based on maximum ES. Note that "regeneration" does not include life flasks, as they are just "Recovery".
