Influenza virus vaccine, trivalent (RIV3), derived from recombinant DNA, hemagglutinin (HA) protein only, preservative and antibiotic free, for intramuscular use
CPT4 code
Name of the Procedure:
Influenza Virus Vaccine, Trivalent (RIV3), Derived from Recombinant DNA, Hemagglutinin (HA) Protein Only, Preservative and Antibiotic-Free, for Intramuscular Use
Summary
This procedure involves administering a flu vaccine to protect against three different strains of the influenza virus. The vaccine is given through an intramuscular injection and is designed using recombinant DNA technology, which includes only the hemagglutinin (HA) protein to stimulate an immune response.
Purpose
The primary purpose of this vaccine is to prevent influenza (the flu), a contagious respiratory illness caused by influenza viruses. The goal is to reduce the risk of flu-related complications, hospitalizations, and mortality, particularly during the flu season.
Indications
This vaccine is recommended for:
- Individuals aged 18 years and older.
- People with chronic health conditions like asthma, diabetes, or heart disease.
- Anyone with a high risk of flu complications, including pregnant women and the elderly.
- Those working in healthcare or other settings with increased risk of flu exposure.
Preparation
- Patients should inform their healthcare provider of any allergies, especially to eggs or prior vaccinations.
- No specific fasting or medication adjustments are typically required.
- An initial health assessment may be conducted to ensure the patient is free from acute illness or fever.
Procedure Description
- The patient is seated comfortably.
- The injection site, typically the upper arm, is cleaned with an antiseptic.
- Using a sterilized needle and syringe, the healthcare provider administers the vaccine intramuscularly.
- The injection site is covered with a bandage, and the patient is monitored for a brief period for any immediate adverse reactions.
Duration
The vaccination procedure typically takes less than 5 minutes, with an additional 15 minutes of observation time recommended.
Setting
This vaccine can be administered in various settings, including outpatient clinics, pharmacies, doctor's offices, or healthcare facilities.
Personnel
- Registered Nurse (RN) or Licensed Practical Nurse (LPN) usually administers the vaccine.
- Physician or Nurse Practitioner may be available for supervision and immediate care in case of adverse reactions.
Risks and Complications
- Common side effects include mild pain or swelling at the injection site, low-grade fever, and muscle aches.
- Rare but serious risks include severe allergic reactions (anaphylaxis), which require immediate medical attention.
Benefits
- Reduced risk of contracting influenza.
- Lowered incidence of severe flu-related complications.
- Protection typically begins approximately two weeks after vaccination.
Recovery
- Patients can return to their normal activities immediately after the procedure.
- It is advisable to monitor the injection site for signs of significant swelling or pain.
- Follow-up is generally not required unless adverse reactions occur.
Alternatives
- Quadrivalent influenza vaccines, which protect against four influenza strains.
- Nasal spray flu vaccines for certain age groups and health conditions.
- Antiviral medications for the treatment of influenza post-exposure.
Patient Experience
- Patients may feel a quick pinch or sting during the injection.
- Mild soreness at the injection site is common and can be managed with over-the-counter pain relievers.
- Most individuals experience minimal discomfort and can resume normal activities shortly after.
By understanding this procedure, patients can be better prepared for their flu vaccination and its benefits in preventing influenza and its complications.
