I have a friend who is anti mRNA vaccines as they are so new.
Are they?

Herd immunity only works if the herd is immune. If only a portion of the herd is immune, the rest of the herd will spread disease.
It requires a critical mass to work, and it protects those who can not get the vaccine for medical reasons (like allergic reactions, etc.)
It also only works if the herd remains immune. We are now seeing a return of diseases that had previously been eliminated (not eradicated), due to a decline in vaccinations. Examples include measles and whooping cough.
