          "valueMarkdown": "Countries where varicella is an important public health burden could consider introducing \nvaricella vaccination in the routine childhood immunization programme. However, resources should be \nsufficient to ensure reaching and sustaining vaccine coverage ≥ 80%. Decision-making on childhood \nvaricella vaccination should also include consideration of the possible impact on herpes zoster. \nThe number of doses recommended is dependent on the goal of the vaccination programme. One dose is \nsufficient to reduce mortality and severe morbidity from varicella but not to prevent limited virus \ncirculation and outbreaks. Two doses have higher effectiveness and should therefore be recommended in \ncountries where the programmatic goal is, in addition to decreasing mortality and severe morbidity, to \nfurther reduce the number of cases and outbreaks.\n\nDepending on the goal of the vaccination programme, 1–2 doses should be given with the first dose administered \nat 12–18 months of age.\n\nVaricella-containing vaccine can be administered concomitantly with other vaccines included in the routine \nchildhood immunization programme. Unless given together with other live viral vaccines (measles, MR \n[measles and rubella], MMR [measles, mumps and rubella]), it should be administered at a minimum interval \nof 28 days.\n\nThe minimum interval between doses should be as recommended by the manufacturer, ranging from 4 weeks to 3 months."
