Immunity & Infections

Colds, flu, vaccination and how to support the defences that keep you well.

Overview

Your immune system fends off countless threats. Understand how everyday infections spread, when antibiotics actually help, and how vaccination and simple hygiene reduce your risk.

What's worth remembering

Most coughs and colds are viral and ease with rest, fluids and time.
Antibiotics treat bacterial infections only — using them needlessly does harm.
Staying up to date with recommended vaccines protects you and those around you.
