What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing if a flu shot can help women undergoing IVF get pregnant. The study focuses on women who have had trouble with miscarriages or embryo implantation. Researchers think the flu shot might make the immune system more supportive of pregnancy.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

Is the influenza vaccine generally safe for humans?

Research shows that various influenza vaccines, including Flublok, Vaxigrip, Intanza, and Fluad, have been studied for safety in different groups, such as older adults and pregnant individuals. These studies generally found that the vaccines are safe, with some people experiencing mild side effects like soreness or mild reactions, but no major safety concerns were identified.12345

How does the influenza vaccine differ from other treatments for infertility?

The influenza vaccine, typically used to prevent the flu, is unique in this context as it is being explored for infertility, a condition with no standard vaccine treatment. Unlike conventional infertility treatments, this approach leverages the vaccine's ability to stimulate the immune system, which is not a typical mechanism used in fertility therapies.35678

Published Research Related to This Trial

In a clinical trial involving 2640 adults aged 50 and older, Flublok showed non-inferior safety compared to AFLURIA regarding hypersensitivity reactions, with only a slight difference in reported cases (0.15%).
Both vaccines had similar reactogenicity and overall adverse event profiles, indicating that Flublok is a safe alternative for seasonal influenza vaccination in older adults.

In a safety surveillance study of the Vaxigrip and Intanza 15 ยตg influenza vaccines during the 2016/17 season, 1.8% of Vaxigrip recipients and 2.1% of Intanza recipients reported suspected adverse reactions within 7 days, indicating a generally low incidence of side effects.
The safety profiles of both vaccines remained consistent with previous years, with no significant increase in adverse reactions, suggesting that both vaccines are safe for use in the population.

In a study of 483 pregnant individuals vaccinated with the quadrivalent inactivated influenza vaccine (IIV4) over four flu seasons, 98.8% reported live births, indicating a high safety profile for the vaccine during pregnancy.
The rates of adverse infant outcomes, such as preterm birth (7.2%), low birth weight (5.4%), and major congenital malformations (0.8%), were found to be lower than or similar to the general population, suggesting that IIV4 does not pose significant safety concerns for pregnant individuals.
