[Effectiveness of rubella vaccination in the puerperium].

This study investigates the degree of effectiveness of post partum rubella vaccination, measured as percentage of true seroconversions. The vaccine used was RA 27/3. In the years 1983/84 the seronegative rate was 7% of the total number of births. The 270 seronegative women who had given birth during these two years had all been vaccinated post partum. 128 of them were controlled, and a seroconversion rate of 91.4% was obtained.
