1. Flu Vaccines

The flu vaccine, or influenza vaccine, flu shot, or flu jab as it is called, protects against the seasonal flu and its possible clinical symptoms and outcomes. Though the flu is common, it is considered highly contagious and its complications can be severe or even fatal for an elderly if not adequately prevented or taken care of. These complications may include pneumonia, bronchitis, meningitis (brain infection), or infection of the sinus or ear.

 The recommended dosage is 1 flu shot each year, or each season in some cases.
