Says a lot about how many long term survivors they have. Wouldn't the number continue to go up like a prescription for a drug with chronic disease? You would have NRX and total. DCVAX BTW continues to work even after the last shot and does not require patient compliance unlike the 23 hour a day plug and play. It is bad enough for me to keep my cell phone charged. I get it to save my life I would do it but, if I had an alternative like DCVAX, I would opt to do that instead.
