What should you know about cdc flu shot?

The flu shot is a vaccination given by injection. It prepares immune defences to respond to influenza viruses included in the vaccine. It cannot cause influenza. Protection develops after the immune system has had time to respond and may not prevent every respiratory illness, because many viruses cause cold-like symptoms. The product may be an inactivated vaccine, meaning it uses virus material that cannot reproduce. Your clinician considers age, pregnancy, allergies, health conditions and previous reactions before vaccination.

Tell the vaccinator about severe allergies, a previous reaction to a vaccine, current illness, pregnancy or medicines that affect immunity. After the injection, remain where staff can observe you for the period they advise. A sore arm, mild fever, tiredness or headache can occur and usually settles with simple care. Drink fluids and rest if needed. Follow local seasonal vaccination advice because influenza viruses and vaccine recommendations can change. Keep your vaccination record and ask when the next dose is due.

Seek emergency help for difficulty breathing, swelling of the face or throat, widespread hives, fainting or sudden severe weakness after vaccination. These can signal a serious allergic reaction. Contact a clinician for a fever that is high or persistent, symptoms that are worsening, or a concern about an unusual reaction. If you are acutely unwell on the appointment day, ask whether vaccination should be postponed. A vaccine does not replace assessment when flu symptoms are severe or a person has difficulty breathing.

Is flu vaccination suitable with my health conditions and medicines? Which product will I receive? What reactions should I expect? When should I seek help after the injection?
