Which of the following statements regarding the inactivated influenza vaccine (IIV) is true?

The statement that pregnant women can safely receive the inactivated influenza vaccine (IIV) is accurate. The IIV is recommended for pregnant individuals because it helps protect both the mother and her developing fetus from influenza, which can pose serious health risks during pregnancy. The vaccine is made from killed virus particles, meaning it cannot cause the infection itself, making it safe for this population. Furthermore, vaccination during pregnancy can also provide some immunity to the baby after birth.

The other statements are not correct. The IIV does not contain a live virus; it is composed of inactivated strains of the virus. It is also not limited to only healthy individuals; people with chronic health conditions, older adults, and those with compromised immune systems can receive the vaccine. However, while the IIV significantly reduces the risk of influenza illness, it does not provide complete protection against all strains of the virus, as the circulating strains can vary from year to year.
