Vaccine – Meaning, Definition, Synonyms and Antonyms
Vaccine (noun) means a medical preparation that helps the body build protection against a particular disease.
Meaning:
A vaccine is a medical biological preparation that provides immunity against a specific infectious disease by training the body’s immune system to recognize and fight pathogens, such as bacteria or viruses.
Definition:
It typically contains weakened, inactivated, or synthetic components of a microorganism, such as proteins or genetic material, that mimic the actual pathogen without causing the disease itself. After vaccination, the immune system can produce antibodies and memory cells, helping the body respond more quickly and effectively if it later encounters the real pathogen. In practice, vaccines are one of the key tools used in modern medicine to reduce outbreaks and protect both individuals and communities.
Example Sentences:
- The widespread rollout of the vaccine significantly reduced the number of measles cases in the region.
- Researchers are studying a new vaccine strategy to improve protection against future viral variants.
- My doctor advised me to get the flu vaccine each season.
- Community outreach efforts helped address vaccine hesitancy by sharing clear information.
