Even a large fund won't typically sway decision of another fund. Hence why you sometimes see public battles between Hedge Funds over some stocks ... Herbalife.

Dendritic Cell therapy has a long history of failed treatments. Other Funds probably weighed that history against NWBO's current valuation against Woodford's track record and investment along with other variables such as AF's bashing, Cash Burn, Public/Doctor's Knowledge, etc and decided history will repeat itself.

They also might be betting that people are jumping on to a bandwagon by tagging along with Woodford. Thus, the valuation they are buying in is far to rich for where it truly should be at it's current stage.

Tons of reasons to explain a short interest increase.

Why short interest hasn't dropped, it could be because Funds are not able to deliver the shares BUT these funds are Hedged.

For example, Funds that have shorted shares might have purchased long term Call options as hedges. Unfortunately, to unwind the trade the fund will have to wait until the option expires. It cannot just sell all of the options and use those proceeds to buy shares on the open market. As this kind of buying volume buying will increase their losses on the short positions AS WELL AS increase the cost of acquiring the required number of shares in order to exit the trade. Thus, to properly exit the trade, the fund has to wait till the option expires and receive the promised shares.

Probably a simplistic example, but COULD explain why Short Interest only increases. Holders can't get out, but speculators keep entering.
