Final answer:
Epinephrine should be available when administering a mumps vaccine to an adolescent in case of a severe allergic reaction. The MMR vaccine is used to prevent mumps and is typically safe and effective.
Step-by-step explanation:
When administering an adolescent's mumps vaccine, it is essential to have emergency medication on hand in case of an adverse reaction, such as an allergy. The most important medication to have available is epinephrine, which is used to treat severe allergic reactions (anaphylaxis). No specific antiviral medications like acyclovir or antibiotics like tetracycline, doxycycline, macrolides, or beta-lactams are typically required during vaccination since they do not counteract vaccine side effects or allergic reactions. The MMR vaccine is used to prevent mumps, measles, and rubella and is part of the recommended immunization schedule for children and adolescents. Vaccines, including the MMR vaccine, have made mumps a rare disease in places where vaccination rates are high.
