Influenza Vaccination: What You Need to Know

Introduction

Influenza, commonly known as the flu, is a viral infection that affects the respiratory system, primarily the nose, throat, and lungs. It is caused by influenza viruses, which are divided into four types: A, B, C, and D. The flu virus is highly contagious and can spread through respiratory droplets when an infected person coughs, sneezes, or talks.

Influenza can cause a range of symptoms, including fever, chills, body aches, fatigue, headache, cough, sore throat, and runny nose. In severe cases, influenza can lead to complications such as pneumonia, bronchitis, and even hospitalization.

Influenza vaccination is the most effective way to prevent the flu and its complications. The influenza vaccine is a safe and effective way to protect people of all ages against the flu.

Types of Influenza Vaccines

There are two main types of influenza vaccines: inactivated influenza vaccines (IIVs) and live attenuated influenza vaccines (LAIVs).

IIVs are made with inactivated (killed) influenza viruses. They are the most common type of influenza vaccine and are available in both injectable and nasal spray forms.

LAIVs are made with live, weakened influenza viruses. They are only available as a nasal spray and are not recommended for certain people, such as pregnant women, people with weakened immune systems, and children under 2 years of age.

Influenza vaccination has many benefits, including:
