Answer 2

Answer:

They are the most effective way of inserting medicine.

If they weren't needles, they would definitely be used more.

Explanation:

Many times vaccines need to be administrated into muscles and strong tissue, so they need a needle to get all the way through. Other ways of giving vaccines are proved to be less potent and do not work as well.

Research also shows that 24% of parents fear needles and 63% of children fear needles.
