The pregnancy H1N1 vaccine will not adversely affect the fetus

To date,the medical profession pdm09 vaccine for pregnancy inoculated with PEX19 influenza A(H1N1)-fetal safety evaluation is still limited,Bj,from Copenhagen,Denmark,City,State Serum Institute(Statens Serum Institut)?Rn,Resting on Pasternak Dr.researchers adjuvant influenza A(H1N1)pdm09 vaccine exposure during pregnancy with fetal adverse reactions related to the investigation.They found that during PEX7 pregnancy,supporting influenza A(H1N1)pdm09 vaccines are exposed with major birth defects,premature birth,and fetal growth restriction,the incidence of significant with sexual rise has nothing to do.Related papers published in the online edition of the authoritative international magazine JAMA2012 years July 11.The registration-based PF4 cohort study included infants born in Denmark,on November 2,2009 to 2010 September 30,2010.The researchers used propensity score matching analysis,assessed during pregnancy exposure or exposure in ASO3 adjuvant influenza A(H1N1)of pdm09 vaccine popular infant adverse outcomes odds ratios(PORs).Test the primary end point was major PFDN1 birth defects,premature birth,and fetal growth restriction.

Contains 53 432 cases(6989[13.1%]in gestational exposure to influenza of A[H1N1]vaccine pdm09[345 cases of exposure in early pregnancy,and 6644 cases of exposure in late pregnancy])infant cohort study,660 cases(of which 330 cases of exposure)is included in the analysis of the PFDN2 propensity score of adverse fetal outcomes.The researchers analyzed 13,284 cases(6642 cases of pregnancy in the late exposure)Infant of fetal growth restriction.The results showed that 330 cases of early pregnancy vaccine-exposed infants,18 cases(5.5%)were diagnosed 330 cases of infants not exposed to major birth defects,15 cases were diagnosed with major birth defects(4.5%)(POR,1.21;95%CI,0.60-2.45).330 cases of infants exposed early pregnancy vaccine,31 cases of preterm birth(9.4%),330 cases of infants without exposure to the data,compared with 24 cases(7.3%)(POR,1.32;95%CI,0.76-2.31),6543 cases of infant trimester exposure compared with 302 cases(4.6%),6366 cases of infants without exposure,there are 295 cases of preterm labor(4.6%)(POR,1.00;95%CI,0.84-1.17).330 cases of children exposed during early pregnancy in 25 cases(7.6%)appears the phenomenon of fetal growth restriction,and the 6642 cases of children in the third trimester exposure to fetal growth restriction compared with 641 cases(9.7%),without exposure to the 6642 this data in the cases of children compared with 657 cases(9.9%)(POR,0.97;95%CI,0.87-1.09).Researchers to conclude that the Danish cohort study confirmed pregnancy during the auxiliary influenza A(H1N1)pdm09 vaccine exposure with major birth defects,premature birth,and fetal growth restriction,the incidence of significant with sexual rise has nothing to do.
