Does H1N1 vaccine cause infertility

Answer 1

Vaccines affect different people in different ways.

That said, the H1N1/09 potential severity is an exaggeration, and there have been a large number of instances across Asia where the vaccination has been linked to a sudden onset of infertility or miscarriage in patients.

Research any vaccine that you feel you may want to take, and arm yourself with the facts, it might mean the difference between life and death.

NO.

This concern goes back to 2008 and before (before H1N1/09). It is mostly derived from information about infertility in mice, in some trials of influenza vaccines, that indicated the vaccine could be linked to problems with reproductive function...in mice. However, currently the links in humans appear to be only anecdotal and coincidental or extremely rare and not yet analyzed fully.

The data collected and reported by the Vaccine Adverse Event Reporting System (VAERS) about adverse events from H1N1/09 vaccines, does not include a concern about this for humans from use of the current flu vaccines. However, it is always evaluated and reports are encouraged for follow up study which is ongoing.

The American Congress of Obstetricians and Gynecologists (ACOG) does not list this as a reason to avoid vaccinations for the H1N1/09 influenza, and they are still strongly encouraging the use in both pregnant women and those who are desiring pregnancy because of the high risk of complications and death from the H1N1/09 flu in that population. The risk of having the flu with complications and/or death is still significantly greater than the risk of untoward effects of vaccinations in women.

Knowledge is always important in health care decisions. Read all you can find, ask your health care professionals and pharmacists often about things you read or hear. Stay alert to information from the right sources such as the Centers for Disease Control and Prevention (CDC), the US Food and Drug Administration (FDA) and the proper sources of other information, such as the ACOG and other Boards of Medical Specialties. If you are not yourself a health care professional who can evaluate and interpret the medical specialty reports, and if you have a concern, go to the proper sources on the internet and ask your doctor.

Use discretion when it comes to believing what you hear and read. There is so much available on the internet, not all of which comes from valid and reliable sources, it is difficult to discern fact from fiction from fears. Ask your doctor if what you have read is valid. There is a lot of speculation, misinformation, and undue concern along with pertinent and factual information available at our fingertips today.

Although there may be anecdotal evidence to suggest this, and there is the study in mice, there are no analyzed reports of infertility in women as an adverse effect of the vaccine or a trend in the incoming data to VAERS that have been released by the VAERS reporting system for vaccine adverse events. No changes have been made in the recommendations for use of the flu vaccines.

Remember that these vaccines contain all the same ingredients and are made the exact same way as seasonal influenza vaccinations have been for decades of use (including Polysorbate 80, the ingredient that has been the focus of this concern). The only difference in ingredients is the type of flu virus each year included in the vaccines. This has not been a trend found over all these years of use, although for the sake of safety, it is always being monitored and evaluated.

Answer 2

No. It is approved for use in pregnant women (and encouraged since they are a high risk group), so the FDA doesn't think there is any adverse effect to the reproductive system.
