Novavax RSV vaccine given to mothers safe for fetus - study

(Corrects paragraph 1 to "safe for her fetuses" from "effective in protecting infants from the virus"; also fixes headline to comply)

Sept 29 (Reuters) - Biotechnology company Novavax Inc said data from a mid-stage study showed that immunizing a pregnant woman with its RSV vaccine was safe for her fetus.

The trial tested the vaccine against a placebo in 50 healthy pregnant women in their third trimester.

Women who received placebo showed no significant change in their antibody levels, the company said.
