Shingles (Herpes Zoster) Vaccine
Shingles (Herpes Zoster) Vaccine
Shingles (also known as herpes zoster) is a viral infection caused by the herpesvirus, which is the same virus that causes chickenpox.
The disease typically causes a painful, itchy, belt-shaped rash on the back, chest, head, or limbs. The rash may develop blisters, and the pain can last for weeks or even months after the rash has healed.
The illness can be particularly dangerous for older adults and people with suppressed immune systems.
The vaccine prevents contagion and alleviates symptoms. It is advisable to get vaccinated even if you have already had the disease because the virus can stay in your body and reactivate later.
The new vaccine, Shingrix, is recommended for adults over 65. It is covered by the health basket but requires a copayment.
What is shingles (herpes zoster)
Shingles (also known as herpes zoster) is a viral infection caused by the herpesvirus. The virus that causes shingles is called varicella zoster, and it is the same virus that causes chickenpox in children. After the illness subsides, the virus remains dormant in the nervous system for life.
Occasionally, the virus reactivates and becomes shingles. The disease causes pain and blisters all over the body. Many of the patients are adults over the age of 65 because a dormant virus is easier to reactivate with a weakening immune system.
Herpes zoster symptoms
A cluster of small, red bumps on the skin that follows the path of a nerve, typically on the face, head, or chest. The rash is accompanied by intense pain and itching, and after several days, it turns into tingling and aching blisters.
The pain may linger for days after the blisters have dried up and healed (a week to ten days), though. Usually, the discomfort comes before the rash, and on rare occasions, other general symptoms like weakness and fever also manifest. Rarely does the illness manifest without symptoms.
Possible complications
People with suppressed immune systems are more likely to experience complications from shingles, such as bacterial infections. There are medications that can help delay the spread of the virus, and a doctor may prescribe them.
People with healthy immune systems can also experience chronic nerve pain after shingles. This pain can start with the rash and last for weeks or months after the rash has healed. These pains interfere with normal functioning, and regular painkillers do not alleviate them.
Rare complications may include damage to the optic nerve and cornea of the eye and meningitis.
Why should you get the herpes zoster vaccine
The herpes zoster vaccine lowers the frequency and severity of symptoms.
It is also suggested that those who have already had the illness obtain the vaccine because it could recur. If you already have the illness, you must wait until you recover (until all the blisters have healed) in order to receive the vaccine because the vaccine does not cure it. The vaccine lasts for at least 10 years before losing its effectiveness.
The Shingrix vaccine for preventing herpes zoster
As of July 1, 2023, a new shingles vaccine administered in two doses has entered use in Israel.
The Shingrix vaccine against herpes zoster provides better immunity than Zostavax. It is also safe for people with suppressed immune systems.
The Shingrix vaccine is covered by the health basket for adults over the age of 65 and for people over the age of 18 who are at high risk of shingles, such as those with a suppressed immune system. The vaccine involves a copayment.
