Intervacc is trading 3.9% up at €0.10 in pre-market action, extending a volatile rebound after recent sharp swings despite a lack of company-specific catalysts.

  • The move follows a low-volume pullback on July 28 after unexplained gains earlier in the week.
  • Trading appears driven primarily by sentiment and volatility rather than fundamentals, especially as the broader biotech sector remains under pressure.
