Vacunación antigripal en la embarazada

Objective

To describe influenza vaccination coverage in pregnant women and analyze whether influenza vaccination in these women confers protection in their neonates in the first months of life.

Material and methods

Three hundred sixteen neonates were followed-up during an epidemic season. An epidemiologic survey was performed in mothers, which included their influenza vaccination status. In all patients with symptoms compatible with respiratory infection, fortnightly telephone calls and nasopharyngeal aspiration were performed and virological diagnosis was obtained.

Results

A total of 5.7% of the cohort had been vaccinated against influenza during pregnancy and 17.4% of the same sample had been vaccinated in the previous season. The only factors significantly influencing vaccination were vaccination in the previous season (OR: 11.35 [7-31]) or in cohabitants (OR: 19.9 [6.7-59.5]). No cases of influenza virus were detected.

Conclusions

The percentage of pregnant women vaccinated against influenza is very low. Information could improve these results. No conclusions can be drawn on the study hypothesis.
