Correlation between flu vaccines and increases in miscarriage


Has babyQ reviewed any of the information reported by V.A.E.R.S. about any correlation between the flu vaccine that contains H1N1 and increases in miscarriage? Is there validity to this?


Here is the summary statement from the Journal of Human and Experimental Toxicology dated  September 27, 2012:

The unadjusted fetal-loss report rates for the three consecutive influenza seasons beginning 2008/2009 were 6.8 (95% CI: 0.1–13.1), 77.8 (95% CI: 66.3–89.4), and 12.6 (95% CI: 7.2–18.0) cases per million pregnant women vaccinated, respectively. . Thus, a synergistic fetal toxicity likely resulted from the administration of both the pandemic (A-H1N1) and seasonal influenza vaccines during the 2009/2010 season.

It appears the multifold rise in miscarriages was primarily in women who received both vaccines, not specifically H1N1, according to the conclusion in the abstract on the web site.  We do know that women who suffer the flu during pregnancy have a slight increase in autism in their children presumably related to the effects of the flu.  So you probably want to be vaccinated with the seasonal flu vaccine to reduce that risk.  However, this article would argue against being vaccinated by both the seasonal flu vaccine and the H1N1 vaccine.  Also I we always recommend spending the extra 5 dollars for the single dose without preservative to eliminate any mercury concerns.  The nasal vaccination also contains no mercury (thimerosal) preservatives.

Here is the statement from the CDC on that issue:

The single-dose units are made without thimerosal as a preservative because they are intended to be opened and used only once. Additionally, the live-attenuated version of the vaccine (the nasal spray vaccine), is produced in single-dose units and does not contain thimerosal.
