The recent history of star formation in VIIZw 403 is analyzed taking into account the dynamics of the starburst blown superbubble and the restrictions that follow from X-ray observations, and from our H$\alpha$ data. Our results show that the starburst energizing VIIZw 403 is NOT coeval, but rather the star forming phase has lasted for more than 30Myr and at such a low pace that most probably the newly processed metals will not be ejected into the intergalactic medium.
