Varicella In Vaccinated Persons
Breakthrough varicella on the abdomen of a vaccinated child.
Breakthrough varicella is infection with wild-type varicella-zoster virus occurring in a vaccinated person more than 42 days after varicella vaccination. Breakthrough varicella is usually mild. Patients typically are afebrile or have low fever and develop fewer than 50 skin lesions. They usually have a shorter illness compared to unvaccinated people who get varicella. The rash is more likely to be predominantly maculopapular rather than vesicular. However, 25% to 30% of people vaccinated with one dose who get breakthrough varicella will have clinical features similar to unvaccinated people with varicella.
Since the clinical features of breakthrough varicella are often mild, it can be difficult to make a diagnosis on clinical presentation alone. Laboratory testing is increasingly important for confirming varicella and appropriately managing the patients and their contacts. Breakthrough varicella occurs less frequently among those who have received two doses of vaccine compared with those who have received only one dose disease may be even milder among two-dose vaccine recipients, although the information about this is limited.
Who Shouldnt Receive Shringrix
Although vaccines go through rigorous safety testing to ensure they are safe, they arent suitable for everyone. You shouldnt receive Shingrix if you:
- have an active shingles infection
- have a severe illness or a fever of 101.3°F or higher
- have had a severe allergic reaction to Shingrix or any ingredient in the vaccine
- have no immunity to varicella based on a blood test carried out for other reasons
- are pregnant or breastfeeding
If you currently have shingles, another serious illness, or a fever of 101.3°F , wait until these issues have resolved to receive a Shingrix vaccination.
What Are The Shingles Vaccines
There are 2 vaccines, Shingrix® and Zostavax® II, that protect against shingles. Shingles is caused by the varicella zoster virus, which also causes chickenpox. Zostavax® II contains a weakened form of the virus while Shingrix® contains only a part of the virus. The vaccines are approved by Health Canada.

What Are The Advantages Of Getting The Shingles Vaccine
The shingles vaccine reduces your risk of getting shingles. Shingles causes a painful rash that usually develops on one side of your body or face. Some people describe the pain as an intense burning or shooting sensation. The rash is often a single strip that wraps around one side of your body or is on one side of your face. It consists of blisters that normally crust over in seven to 10 days. The rash generally clears up within a month.
Some people with shingles also experience additional symptoms including fever, headache, chills or upset stomach.
For some people, the pain from the rash can last for months or even years after the rash goes away. This long-term pain is called postherpetic neuralgia , and it is the most common complication of shingles.
How Long Does Shingrix Last
The immunity conferred from Shingrix for the prevention of shingles is thought to last longer, and be more effective than the previous shingles vaccine, Zostavax.
The immune response from the shingles vaccine Shingrix is reported to be at least nine years based on the cellular response to the vaccine according to the CDC. However, âimmune responseâ doesnât necessarily correlate to vaccine effectiveness in terms of preventing episodes of shingles.
Other data indicates that the Shingrix vaccine maintains greater than 90% efficacy at least four years after vaccination according to GlaxoSmithKline, the manufacturer of the vaccine.
In addition, the New England Journal of Medicine has reported that Shingrix maintains around 88% efficacy at least four years after vaccination in patients vaccinated 70 years of age or older.

What Is Shingles / Herpes Zoster
- Shingles, also known as herpes zoster, is caused by the same virus as chickenpox. After chickenpox blisters heal, the herpes zoster virus stays, hiding in the bodys nerve cells.
- The virus may be inactive for many years, but for unknown reasons, it can become active again and cause shingles. It can happen to anyone who has had chickenpox, but the risk increases as you get older, especially if you are over 50 years of age two thirds of shingles cases occur over the age of fifty.
- Nearly one in three Canadians develops shingles during their lifetime.
- Shingles causes a painful, blister-like rash that usually appears on one side of the body or face. Up to 4 days before the rash appears, there is often pain, itching or tingling at the site.
- The blisters scab over in 3 to 5 days and can last for 2 to 4 weeks. You might also have a fever, chills, headache and upset stomach.
- In addition to the pain from the rash, the underlying nerve pain caused by shingles has been described as burning, throbbing and/or stabbing. It can last for months or years.
- People with shingles may have other complications, including scarring, bacterial skin infections, weakness, muscle paralysis and loss of hearing and/or vision.

Impact Of The Varicella Vaccination Program
Varicella used to be very common in the United States. In the early 1990s, an average of 4 million people got varicella, 10,500 to 13,000 were hospitalized, and 100 to 150 died each year.
Varicella vaccine became available in the United States in 1995. Each year, more than 3.5 million cases of varicella, 9,000 hospitalizations, and 100 deaths are prevented by varicella vaccination in the United States.
Highlights from Our Data
Why Is Shingrix Administered In Two Doses
Shingrix is typically given in two doses, usually as a shot to the upper arm.
A 2021 study found that adults over 65 were significantly less likely to develop either shingles or PHN after getting two doses of Shingrix than they were after one dose. Two doses of Shingrix also offered better protection against shingles complications to adults over 80 and immunocompromised adults.
Previously, Zostavax was offered to older and immunocompromised adults to prevent shingles, PHN, and other shingles-related health problems. Zostavax is a live vaccine, which means it contains a weakened version of the herpes zoster virus. Shingrix is a recombinant vaccine, meaning that it uses only a small piece of the virus.
In 2017, the Food and Drug Administration approved Shingrix for the prevention of shingles and related complications. Zostavax is no longer available in the U.S. People who have gotten Zostavax in the past should now get Shingrix.
Studies have shown that Zostavaxa one-dose vaccineis generally less effective than two doses of Shingrix in preventing shingles complications among older and immunocompromised adults. Shingrix currently offers the best chance of protection against shingles, PHN, and shingles-related hospitalization.

- treatment with drugs that affect the immune system, such as steroids,
- cancer treatment such as radiation or chemotherapy, or
- cancer affecting the bone marrow or lymphatic system, such as leukemia or lymphoma.
Someone with a minor acute illness, such as a cold, may be vaccinated. But anyone with a moderate or severe acute illness should usually wait until they recover before getting the vaccine. This includes anyone with a temperature of 101.3°F or higher.

Why Is The Shingles Vaccine Important
Shingles causes a painful rash and blisters and it can lead to serious complications. The most common complication is post-herpetic neuralgia , a condition that causes burning pain that can last long after the shingles rash and blisters go away. The older you are when you get shingles, the more likely you are to develop PHN.
Getting vaccinated is the best way to prevent shingles and PHN.
Shingles is caused by the same virus that causes chickenpox. After you have chickenpox, the chickenpox virus stays dormant in your body. The virus can activate years later and cause shingles.
Symptoms of shingles include:
Shingles cant spread from person to person like chickenpox. But if you have shingles, you can spread the virus to someone who isnt immune to chickenpox meaning someone who hasnt had chickenpox and isnt vaccinated against it. If that happened, the person might get chickenpox but not shingles. Learn more about shingles.
- Adults age 50 and older
- Adults 19 years and older who have a weakened immune system because of disease or treatments

If you have a weakened immune system a GP or practice nurse will assess which vaccine is suitable for you. Discuss any health concerns with the GP or practice nurse before you have the vaccine.
Zostavax is not suitable for people who have a weakened immune system due to a condition, treatment or medicine.
Incubation Period And Prodrome
The average incubation period for varicella is 14 to 16 days after exposure to a varicella or a herpes zoster rash, with a range of 10 to 21 days. A mild prodrome of fever and malaise may occur 1 to 2 days before rash onset, particularly in adults. In children, the rash is often the first sign of disease.

Treating Shingles On The Face
Treatment is the same no matter where shingles develop. Treatment will involve taking an antiviral drug to reduce the severity of the outbreak and help it disappear more quickly.
People will see the best results if they take antiviral medication within 72 hours of the rash appearing.
In most cases, a doctor will prescribe the drugs famciclovir and valacyclovir. People with weak immune systems may need to take a different drug, such as acyclovir, instead.
Most research suggests anti-shingles drugs are safe for people who are breast-feeding, but those who are pregnant or breast-feeding should discuss medications with their doctors.
People who develop PHN may also require pain medication. PHN medication may include oral drugs, such as opioids or creams that people can apply directly to the skin.
The typical shingles red rash or blisters occur after pain, itching, and tingling. They are usually limited to one side of the face and body.
