For grown-ups
Your child just met their body's four everyday defences — the immune "army", white blood cells, the skin barrier, and vaccines as practice drills — and practised a proper 20-second hand wash. The habit they're taking home is G.U.A.R.D. A quick way to make it stick: let them "teach" it back to you tonight.
A child's immune system is still learning. Simple everyday habits — thorough hand-washing, covering coughs, good sleep and varied nutrition — plus on-time vaccination give it the best chance to keep infections mild and rare.
Clinically reviewed · Dr S. P. Rath · Jul 2026
Immunity is one of 16 things we check — vision, hearing, growth, sleep, focus, behaviour and more. Think of it as the holistic vaccine: care that begins before the cry.
