## Definition

having received a medical treatment, usually a needle, that protects you from a specific disease.

For teachers: having been treated with a vaccine to produce immunity against a particular pathogen. Often used predicatively after linking verbs like 'be' or 'get'.

## Examples

- Most children are vaccinated against measles before they start school.
- The clinic confirmed that all staff members were fully vaccinated before the winter flu season began.
- Public health officials emphasized that even vaccinated individuals should remain vigilant during the initial phase of the outbreak to ensure community-wide protection.

## Pitfalls

- Not "I am vaccinated of the flu" but "I am vaccinated against the flu" — The adjective 'vaccinated' typically takes the preposition 'against' rather than 'of' or 'from'.

## Usage notes

- Commonly follows the linking verbs 'be' or 'get'; frequently takes the preposition 'against' followed by the name of a disease.
