Influenza is not a cold
Common colds are often caused by cold or respiratory diseases caused by rhinovirus , coronavirus, bacteria and other pathogens. They are not contagious, have mild symptoms and are self-limiting.
Influenza is usually caused by influenza A or B viruses, and is more contagious than the common cold. Symptoms include sudden fever, cough (usually dry cough), headache, muscle and joint pain, sore throat and runny nose. The cough can be severe and can last for 2 weeks or more. In severe cases, many complications may occur, such as viral pneumonia, , acute respiratory distress syndrome, shock, , diffuse intravascular coagulation, etc.
Flu vaccine common knowledge Q&A
. Is influenza vaccine vaccination every year?
Yes. You cannot be "lifelong immunity" after receiving the influenza vaccine. This is because the influenza virus mutates very quickly, and the immunity generated after vaccination has no cross-protective effect or weak cross-protective effect on the already mutated virus.
In fact, the influenza virus strains that are popular every year are different from previous years. The immunity obtained by the human body after receiving the influenza vaccine will also decay with time, so new influenza vaccines are required every year.
