Answer: The cornea is avascular.
Explanation:
The cornea can be defined as the clear front membrane on the surface of eyeball. It lies in the front of the iris and pupil. It allows the light to enter the eye. A cornea transplant is recommended in patients who suffer from vision problems due to thinning of cornea, keratoconus, loss of vision and cloudiness of cornea.
It takes about 2 to 3 months to recover after surgery. The healing is slow because the cornea is avascular. The tissue of cornea does not provide blood vessels to deliver nutrients and oxygen which could aid in speedy recovery.

A primary reason for needing a new vaccine for influenza each year is that there could be mutation of surface proteins leading to a new outbreak
<h3>What is antigenic drift?</h3>
Antigenic drift is a phenomenon that causes small changes or mutations in the genes of influenza viruses leading to changes in their surface proteins of the virus, which are HA (hemagglutinin) and NA (neuraminidase).
For this reason, new influenza vaccines are produced yearly to alter the effects that may emerge as a result.
Thus, a primary reason for needing a new vaccine for influenza each year is that there could be mutation of surface proteins leading to a new outbreak
