Measles vaccine.

Explanation:

The measles vaccine is necessary for students to attend public schools because measles is a very contagious disease and children are easy to get.

The vaccine that protects against measles is the triple viral and the viral tetra. The triple viral vaccine protects against measles, rubella and mumps. The viral tetra, in turn, protects against measles, mumps, rubella and also chickenpox (chicken pox). The current vaccination schedule recommends one dose of the triple viral vaccine at 12 months of age and another dose, but this time of the viral tetra at 15 months of age.

This vaccine is an attenuated vaccine containing “weakened” live measles, rubella, and mumps viruses; amino acids; human albumin; neomycin sulfate; sorbitol and gelatin. It also contains traces of chicken egg protein used in the vaccine manufacturing process. Upon entering the body, the immune system can combat weakened viruses and memorize how to fight them. This way the immune system can fight a possible measles virus much faster.
