Primary prevention

Two live attenuated viral vaccines for the prevention of rubella are available in the US: a trivalent measles-mumps-rubella vaccine (MMR) and a quadrivalent measles-mumps-rubella-varicella vaccine (MMRV). MMRV is licensed for use in people ages 12 months to ≤12 years only.[12]​​​ CDC: rubella vaccination Opens in new window​​​​​ The RA 27/3 strain rubella component of each of these vaccines is identical. Rubella vaccines are reported to be approximately 97% effective in preventing disease after a single dose.[12] Although 1 dose of rubella vaccine is highly protective, 2 doses of a rubella-containing vaccine are recommended for children and adolescents because of the 2-dose recommendations for measles- and mumps-containing vaccine and to provide additional protection to people who experience primary vaccine failure.[16]​ Depending on age and risk of exposure, 1 or 2 doses are recommended for susceptible adults.[12][17]​​​​​​​ Evidence of immunity to rubella includes documentation of ≥1 dose of rubella-containing vaccine on or after the first birthday, laboratory evidence of immunity, or birth before 1957.[17]​ Adverse reactions to MMR vaccines are infrequent. The most common adverse reactions include low-grade fever, transient rash, and lymphadenopathy.[12]​ Multiple studies have failed to demonstrate a link between MMR vaccines and autism.[18][19][20]

As there is a very low incidence of mumps, measles, and rubella in the US, a health provider’s clinical diagnosis of rubella should not be considered acceptable evidence of immunity.[12]​ People at increased risk of rubella infection (healthcare professionals, educators, childcare workers) should be assessed for susceptibility to rubella and, if susceptible, should be immunized with MMR vaccine.​​ CDC: rubella Opens in new window Pan American Health Organization/WHO: rubella Opens in new window

Nonpregnant women of childbearing age who are found to be susceptible by serologic screening or whose immunization status is undocumented should be immunized with one dose of MMR vaccine unless they are known to be pregnant.[17]​ Routine prenatal screening for rubella immunity is recommended.[21]​ MMR vaccine is contraindicated during pregnancy.[17]​ Pregnant people who do not have acceptable evidence of rubella immunity should be advised to avoid travel to countries where rubella is endemic or to areas with known rubella outbreaks, especially during the first 20 weeks of pregnancy. Congenital rubella syndrome is rare when infection occurs at 20 weeks of gestation or later.​[22]​ MMR vaccination should be given to susceptible women in the immediate postpartum period.[17]

Country-specific guidelines should be followed regarding rubella vaccination prior to travel. Vaccination is recommended for all international travelers ages ≥6 months without documented immunity.[23]​ Before departure from the US, infants ages 6-11 months should receive one dose of MMR vaccine (for measles protection), and unvaccinated children ages ≥12 months should receive two doses of MMR vaccine ≥28 days apart.​[16]

Prevenção secundária

Patients with postnatal rubella should be isolated for 7 days after the onset of rash. Droplet and standard precautions are recommended for hospitalized patients.[11]​​

Contact isolation is recommended for congenitally infected infants until 2 serial nasopharyngeal and urine cultures obtained after 3 months of age are sterile, or for the first year of life.
