Immunity (noun): protection against disease, harm, or negative consequences; the state of being resistant to something that would normally cause damage or reaction.

At its core, immunity is about protection over time. It’s not the fight itself, but the condition of being protected — either because your body has learned how to defend itself, or because rules, status, or experience shield you from harm.

In everyday English, immunity is used in three main areas: health, law, and metaphorical life situations. You can have immunity to a virus, legal immunity from prosecution, or emotional immunity to criticism. The common idea is always the same: something no longer affects you in the usual way.

MEANING 1: Biological Protection Against Disease — VERY COMMON

In medicine and daily life, immunity means your body is able to resist infection. This protection usually develops through vaccination or previous exposure. Immunity doesn’t always mean you never get sick — it often means the illness is weaker or shorter.

MEANING 2: Legal or Official Protection

In law and politics, immunity means someone is protected from legal action. Diplomatic immunity, parliamentary immunity, or immunity from prosecution all mean normal rules don’t apply in the same way.

MEANING 3: Resistance to Emotional or Social Influence — VERY COMMON

Metaphorically, immunity describes emotional strength. If someone develops immunity to criticism, pressure, or temptation, those things lose their power. This meaning is extremely common in spoken English.

Examples from the street:

• “Vaccination gives you immunity” → protection develops
• “He has legal immunity” → the law protects him
• “Experience builds immunity to criticism” → comments lose impact

2. Most Common Patterns
