^ Agreeing with the Hep A and B jabs ... but that should be part of your vaccine program living in the West.
Also, something to consider is updating your vaccine for someone over the age of 50.
Shingles is caused by the same virus responsible for chickenpox.
Shingles, also known as herpes zoster, is caused by the varicella zoster virus, which is also responsible for chickenpox. It occurs because of a reactivation of the chickenpox virus, which remains in the nerve cells of the body after an attack of chickenpox.
People who get
chickenpox are at risk of developing shingles later in life, since the virus lies dormant in the body. Fortunately, it is rare to have more than one attack of shingles.
Anyone who has had chickenpox can develop shingles. However, people who have never had chickenpox can catch the virus from another person with shingles. A person who has never had chickenpox, but comes into contact with a case of shingles, would develop chickenpox (not shingles).
Depending on where the person is staying, maybe consider the rabies shots?
