De Vega first made an impact at the 1981 Southeast Asian Games (SEA Games) held in Manila with gold medal performances in the 200 and 400 meter events exceeding records set at the Asian Games. As Asia's sprint queen, she ran away with the gold medal in the 100-meter dash in the 1982 Asian Games in New Delhi and duplicated the feat in the same event at the 1986 edition in Seoul where she clocked 11.53 seconds. She developed a rivalry with Indian athlete P. T. Usha.

De Vega won the gold in the 100 meters at the SEA Games (1987, 1991 and 1993). She also topped the 200 meter event in 1981, 1983, 1987 and 1993.

They first met at the 1979 Asean Schools Track and Field Championships in Singapore and were together for six years prior to both of them entering separate marriages.

De Vega would marry another man named Paul Mercado in 1990, a former engineer at Meralco and an entrepreneur engaged in the fish pond business, with whom she had three children, including Stephanie (Paneng), who is a former collegiate volleyball player of the DLSU Lady Spikers. On February 13, 2001, her four-year-old son John Michael (JM) (October 31, 1996 – February 13, 2001) died in a car accident.
