I’m in two minds. There’s an outbreak of chickenpox in my 5yo’s school. I have a newborn at home. So I really really don’t want her to catch chickenpox. Now, l can vaccinate my older child but he may be contagious as the vaccine is live virus. He may also have been incubating chickenpox for a while then there’s no need to vaccinate him at all. What do I do? Just leave it for now or vaccinate him ?
