The presence of Euclidean wormholes forms a finite value of the vacuum energy density of zero-point fluctuations. This energy has the form of the cosmological constant, and it still has an enormous value. To meet observational restrictions, such a value should be subtracted by hands. Then, the rest energy may violate the weak energy condition and allow for the creation of stable Lorentzian wormholes. Moreover, we show that the presence of Euclidean wormholes leads to a series of phase transitions in the early Universe. During those transitions, some macroscopic defects of the domain wall type, which violate energy condition, were formed, and, presumably, this should lead to the birth of a number of relic wormholes.
