1 What is Mumpsvax?

Brand: Mumpsvax

Generic: Mumps Virus Vaccine, Live

An active immunizing agent, live mumps virus vaccine is used in preventing mumps infection. The Mumpsvax works by pushing the body to produce antibodies that will protect against the viral infection.

When mumps infection manifests, it can be very severe that it may cause serious complications like meningitis and encephalitis. Furthermore, the infection may cause the condition called orchitis, which may affect adolescent boys and men.

Orchitis is a condition that causes pain and swelling in the testicles; when lef6t untreated, it may result in sterility.

Women who are pregnant and in their first trimester can experience spontaneous abortion when exposed to the mumps virus. Mumps vaccine is recommended for everyone aged 12 months and above.

It is not recommended for infants younger than one-year-old since the antibodies they had from their mothers may interfere with the vaccine’s effectiveness. If the child was immunized against mumps before 12 months, re-immunization is necessary.
