Dr. Prausnitz says some people may find the microneedles uncomfortable despite their size.

普罗斯尼茨博，管这种微针头很细，也会有人觉得不舒服。

In their report, the researchers say the new technology has microneedle patches that administer a vaccine when pressed against the skin.

The microneedles are either hollow or empty, like a normal hypodermic needle, or covered with a drug which breaks down in the eye.

这种微针头像普通的皮下注射针头样是中空的，或者覆盖了眼睛里分解的药物。

These instruments, called microneedles, can put medication into the front of the eye, exactly where it is needed.

Dr. Prausnitz says some people may find the microneedles uncomfortable despite their size. But he says an anesthetic drug could be used so that a patient does not feel any pain.
