सुरक्षा सलाह: यह टीका डॉक्टर या प्रशिक्षित स्वास्थ्यकर्मी द्वारा लगाया जाता है। अगर आपको पहले किसी टीके या अंडे से गंभीर एलर्जी हुई है तो डॉक्टर को बताएं। अगर आपको खून पतला करने वाली दवा चल रही है या रक्तस्राव विकार है तो सावधानी बरतें। गर्भवती महिलाओं के लिए यह टीका सुरक्षित और लाभकारी है। बुखार या तीव्र बीमारी के दौरान टीका न लगवाएं। टीके के बाद 15 मिनट तक क्लिनिक में रुकें। इंजेक्शन वाली जगह को रगड़ें नहीं।

🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine contains inactivated influenza virus strains. After injection, the immune system recognises the viral proteins as foreign and produces antibodies against them. These antibodies, mainly against haemagglutinin and neuraminidase surface proteins, neutralise the virus if the person is later exposed to similar influenza strains. The vaccine also stimulates memory B cells and T cells, providing longer-term protection. Because the virus is inactivated, it cannot cause influenza.
Mechanism Steps
💡 How to Take fluarix tetra 2021/2022 nh vaccine
Strength: Injection: 0.5 mL single-dose prefilled syringe or vial. Each dose contains inactivated influenza virus strains (NA).
Dosage Information
| Adult Dosage | For adults, a single 0.5 mL dose is given intramuscularly, preferably in the deltoid muscle. The dose is the same for all adults regardless of age. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. Annual vaccination is recommended before the influenza season. |
| Pediatric Dosage | For children aged 6 months to 8 years, the dose is 0.25 mL or 0.5 mL depending on the product, given intramuscularly. Children receiving influenza vaccine for the first time may need two doses given at least four weeks apart. For children 9 years and older, a single 0.5 mL dose is given. Pediatric dosing is not established from available information for infants under 6 months. Consult a pediatrician. |
| Elderly Dosage | The dose for elderly patients is the same as for younger adults: a single 0.5 mL intramuscular injection. However, the immune response may be lower, so high-dose or adjuvanted formulations may be recommended for those above 65 years. Consult your doctor. |
| Renal Impairment | No dose adjustment is required for patients with renal impairment. |
| Hepatic Impairment | No dose adjustment is required for patients with hepatic impairment. |
