Decision on Vaccine/Herceptin Trial

We've decided to complete 24 weeks of chemo/Herceptin before enrolling in the study. This is week 15. I think it's best not to rock the boat since it's doing the job so I'm going to play it safe; hopefully I'll be NED for sure by then! Also a factor was the possibility of the study filling up before I finished my regimen but so far 5 people are enrolled and they will take 20 so I think I'll still be able to get in.
I feel good about this decision that I'm going to have the best chance for long term control by hopefully ensuring that I'm NED before entering the trial.
