How Do You Pronounce "vaccine"?
"vaccine" is pronounced VAK-seen /ˈvæksiːn/. The stress is on the first syllable (VAK). As a noun, it means a substance given to protect the body against a particular disease.
In British and Indian-taught English the stress is on the FIRST syllable, VAK — not on 'SEEN' at the end.
Note: US commonly stresses the second syllable, /vækˈsiːn/ ("vak-SEEN"); the UK and Indian-taught lead is first-syllable VAK-seen.
