How many ATG/Cyclosporin rounds

[JodyW]

My son has had 2 rounds of ATG/Cyclosporin in the last 2 years. How many times can one have them. Both were horse. Just wondering what happens if this round fails.

There seems to be no limit. See for example Andrea Pecor's Personal Profile, describing her 5 rounds of ATG (so far!).
