Shares in Hvivo, a UK-based medical and scientific research firm, were up 35p to trade at 65.1p after the company announced on Monday it had moved nearer to discovering a universal flu vaccine.
The share price move followed what Hvivo termed a “significant advance in the management of influenza disease” after seeing positive results in a phase llb trial of its FLU-v treatment.
On Wednesday morning Hvivo shares were trading higher still, hitting 86.5p before dipping slightly to 79p and then levelling around 72p. However, they remain down about 70% over the last calendar year.
The move shows a sharp reversal in fortune for a company that in April issued a statement after its shares plummeted about 50% noting the “sudden and extreme fall” in its share price and admitting it “knows of no reason for such a fall”.
It said at the time it was optimistic that its investment in FLU-v had “potentially significant future value”.
Earlier this week, analysts at Numis Securities reissued a buy rating on the firm.

Woodford’s Prothena holding became the focal point of the latest annual results for his Patient Capital Trust.
