I am all but decided that I would like for my son (16 months) to have the chickenpox vaccine, but have just read online that, as it's a live vaccine, "It’s therefore important to avoid contact with anyone in an ‘at risk’ group for six weeks after each dose of vaccination. Those most at risk include pregnant women who haven’t had chickenpox, newborn babies of mothers who haven’t had chickenpox, or anyone with a weakened immune system." How would this work with going to nursery - I don't know everyone there and wouldn't therefore necessarily know if baby could come into contact with someone in these categories. I can't realistically keep him off nursery for six weeks, so should I not get him the vaccine? Interested to know how others who have had the vaccine have managed.
