Researchers at the Centers for Disease Control and Prevention believe pregnant women can safely receive the meningococcal vaccine Menactra, by Sanofi Pasteur. The team reviewed data from the Vaccine Adverse Event Reporting System from 2005 to 2011 and available medical records. There were 103 reports in all, but only 65 described any adverse event; the remaining 38 were submitted only because of vaccine exposure during pregnancy. The most frequent adverse event was spontaneous abortion in 17 cases (16.5 percent); spontaneous abortions occur in 15 percent to 20 percent of all pregnancies, the researchers said. Urinary tract infections (3.9 percent) and fever with vomiting (2.9 percent), also common in pregnant women, were the most frequent non-pregnancy related events. “Our findings, despite being limited to passive surveillance data, did not identify any safety concerns when MCV4 is used in pregnant women,” said Dr. Yenlik A. Zheteyeva, who led the study. The findings are published in the American Journal of Obstetrics & Gynecology.
