The data at http://www.nasdaq.com/symbol/nwbo/short-interest does suggest that shorting of NWBO has been primarily accumulated the past year. Only ~500k short interest in Aug 2013 as maverick pointed out.

Took the yearly chart and looked at the stock price vs how many new shorts that were accumulated each month. I have two columns in my table for price, Peak PPS - which is the peak stock price that month. Very limited volume were traded at that price so I added a second column, ShortAvgPPS, which is a rough guesstimate of the average price the short positions would have been taken at that month. If you then look at the number of short positions taken each month, vs the ShortAvgPPS price you can see that most shorts were taken in Nov 2013 - where over 2 million new shares were shorted at a ShortAvgPPS around $6.00, possible below $6.00. They are under water now.

The second biggest month for shorting was Jan 2014 where another million shares were shorted at $5.10 average (roughly). They are even more under water.

The PPS were higher in March and Jun and it's not unlikely some shorts averaged up there. But I do think this graph paints a pretty clear picture. Many shorts are under water and at risk of loosing serious $$$ if stock price is allowed to run away. That explains all bashing, law firm investigations etc etc. Shorts are in trouble IMHO.
