Does the flu vaccine protect against both influenza A and influenza B?

The influenza vaccine can prevent both type A and type B flu. Type A flu refers to influenza A, and type B flu refers to influenza B. The influenza vaccine protects against many strains of the influenza virus, including influenza A and influenza B viruses. Getting vaccinated against the flu effectively helps prevent infection. Additionally, individuals should get plenty of rest and avoid overexertion; maintain a light diet; drink ample warm water daily to promote metabolism; and exercise regularly to strengthen the immune system. If any symptoms occur, medical attention should be sought promptly at a hospital to avoid delaying treatment.
