Which statement is true regarding seasonal influenza vaccines?

The statement that inactivated vaccines can be given to pregnant women is correct because inactivated influenza vaccines are safe and recommended for use during pregnancy. Pregnant women are at a higher risk for severe illness from influenza, and vaccination helps protect both the mother and the fetus. The inactivated vaccine does not contain live virus, so it poses no risk of causing the disease in pregnant women or their unborn children.

Inactivated vaccines are specifically designed to evoke an immune response without the risk associated with live vaccines, making them suitable for vulnerable populations, including pregnant women. It is crucial for healthcare providers to encourage vaccination among this group to enhance their protection against influenza, especially during flu season.

The other options present challenges or inaccuracies regarding the recommendations for influenza vaccines. For example, seasonal influenza vaccines may not be effective for all populations due to various factors like individual health conditions or immune responses. Live vaccines, on the other hand, are not typically recommended for older adults as they are more suited to younger, healthier populations, and vaccines should ideally be administered before flu season begins to ensure immunity is built up in time for peak flu activity.
