The NHS said: “It’s possible to get chickenpox more than once, but it’s unusual.”
If you do get chickenpox more than once, the symptoms tend to be exactly the same – though your existing immunity to it can make it less intense.
Developing the “very itchy” rash is almost guaranteed, though adults will often develop more spots than children who become infected with chickenpox.
According to the NHS, adults will usually have a higher temperature for longer too.
This means that if you have chickenpox twice – once as a child and again as an adult, you will likely experience worse symptoms the second time around.
