Chickenpox - Prevention 

Preventing the spread of chickenpox 

Tips for parents

See the pregnancy and baby guide for practical advice about all aspects of parenting, plus videos and interactive tools to help you and your child stay healthy. 

If your child has chickenpox, the Health Protection Agency recommends that you inform their school or nursery, and keep them at home for five days.

If you have chickenpox, stay off work and at home until you're no longer infectious, which is until the last blister has burst and crusted over. This usually happens five or six days after the rash begins.

If either you or your child has chickenpox, it is also a good idea for you, or them, to avoid contact with:

  • pregnant women
  • newborn babies
  • anyone who has a weak immune system, such as people who are having chemotherapy (a treatment for cancer) or taking steroid tablets

If you or your child have recently been exposed to the chickenpox virus, you may not be able to visit friends or relatives in hospital. Telephone the ward to check first.

Travelling on a plane 

If you or your child have chickenpox, you may not be allowed to fly until six days after the last spot has appeared.

You and your child should be safe to fly once you're past the infectious stage and all of the blisters have crusted over. However, it's best to check the policy of your airline first. Inform the airline as soon as chickenpox is diagnosed.

It is also important to let your travel insurer know if you or your child has chickenpox. You need to make sure that you'll be covered if you have to delay or cancel your holiday, or if you need to extend your stay until your child is well enough to fly home.

Stop the virus spreading

Chickenpox can sometimes be spread through contact with objects that have been contaminated with the virus, such as children's toys, bedding or clothing.

If someone in your household has chickenpox, you can help stop the virus spreading by wiping any objects or surfaces with a sterilising solution and making sure that any infected clothing or bedding is washed regularly.


There is a chickenpox vaccine that is used to protect people who are most at risk of a serious chickenpox infection or of passing the infection on to someone who is at risk.

People who may be considered for chickenpox vaccination include:

  • healthcare workers who are not already immune – for example, a nurse who has never had chickenpox and who may pass it to someone they are treating if they become infected
  • people living with someone who has a weakened immune system – for example, the child of a parent receiving chemotherapy

The vaccine is not suitable for pregnant women. Avoid getting pregnant for three months after having the vaccine. The vaccine is also not suitable for people with weakened immune systems.

Phayward - its only a rough estimate, as it doesn't include various costs, but the chicken pox vaccines licensed for use in children are around £30+ / dose, and as you probably know, protection is normally based on 2 doses.

A free account is needed to get in, but here's your evidence:

As you'll also see from various medical sites, 90% of the UK population have had chicken pox by the time they're adults, and for the vast majority of children its just a nuisance - like many other childhood diseases - slapped cheek, glandular fever, etc. - which is one of the reasons we don't vaccinate the general population against it.

Some people are more at risk of dangerous complications, which is why their close associates are offered the vaccine - to stop them spreading it to vulnerable people.

As for whether it would be worth vaccinating the entire population, I guess that's one for the politicians - there's no medical reason for it.

One thing we don't really know yet with any certainty - how long vaccine protection lasts - mainly as the vaccine has only been around for a few years. In time we'll know better whether boosters are needed.

There's a vaccination for this which is not routinely even offered and I guess would probably not even be given except in the exceptional circumstances. What about lost work time, distress to the child and the possibility of scarring. Probably the vaccine is less than 50p per child, and the NHS doesn't even make the effort to offer this.
