We are presenting here the new formulae for Bose-Einstein correlations (BEC) which contain effects of final state interactions (FSI) of both strong (in s-wave) and electromagnetic origin. We demonstrate the importance of FSI in BEC by analysing data for e+e- annihilation and for heavy collisions. The inclusion of FSI results in the practical elimination (at least in e+e- data) of the so called degree of coherence parameter λ (which becomes equal unity) and the long range parameter γ (which is now equal zero).
