關於麻疹，腮腺炎，風疹（MMR）疫苗
This vaccine combines three infectious agents to prevent measles, mumps and rubella (German measles). Vaccination is recommended if you are not up-to-date with routine shots. Many childhood diseases, especially measles, are still common in many parts of the world, including highly developed countries. Recently there have been major ongoing outbreaks of measles in children and adolescents who have not been vaccinated due to unfounded concerns about vaccinations in general.
If you are unsure about your or your child’s level of protection against measles/mumps/rubella, see your health care provider for your personal vaccination records and to determine if you or your children require booster shots.
Some vaccines are immediately effective and can be given just prior to departure. Other vaccines require multiple doses before they provide protection. Therefore, it is generally advisable to consult your health care provider at least 4 to 5 weeks before you depart.
排程
MMR vaccine is usually administered in childhood with a first dose at 12 to 15 months of age, followed by a second dose at 4 to 6 years of age. Persons who are 18 years of age or older and who are unsure of their vaccination history should receive one dose of the vaccine prior to travel. Infants aged 6-11 months who are traveling abroad should receive 1 dose of the vaccine. Infants who receive MMR vaccine before age 12 months should be considered potentially susceptible to all 3 diseases and should be revaccinated with 2 doses of MMR vaccine, the 1st dose administered when the child is aged 12-15 months (12 months if the child remains in an area where disease risk is high) and the 2nd dose at least 28 days later. Adolescents and adults who have not had measles or have not been vaccinated should get two doses, separated by at least 28 days.
From 2 to 5 per cent of people do not respond to their 1st dose of measles vaccine, which is why a 2nd (booster) dose is recommended. More than 99 per cent of people develops immunity to measles after 2 doses of a measles vaccine.
副作用
大多數接種MMR疫苗的人沒有任何嚴重的問題。輕度的副作用包括發燒，輕度皮疹和臉頰或頸部腺體腫脹。罕見的副作用包括癲癇發作，關節暫時疼痛或僵硬，以及嚴重的過敏反應。
