How Do You Catch Shingles
You do not “catch” shingles it comes on when there’s a reactivation of chickenpox virus that’s already in your body.
After you’ve recovered from chickenpox, the varicella-zoster virus lies dormant in your nerve cells and can reactivate at a later stage when your immune system is weakened.
Anyone who has had chickenpox can get shingles.
Symptoms And Signs Of Shingles
The primary symptom of shingles is a painful rash that usually develops on one side of the body, frequently on the torso, although it can appear anywhere on your skin. Before the shingles rash becomes visible, you will probably experience pain, tingling or itching in the area where the rash will appear. Once the rash appears, that area will be sensitive to touch, itchy and/or painful. The rash will be made up of blisters that will open and scab over in about a week and then disappear in 2-4 weeks. Other symptoms of shingles can include upset stomach, headache, fever, body aches and chills. Once the rash has disappeared, it is likely that you wont have a recurrence. Most people who get shingles only have one episode in their lifetime. However, some people experience complications from shingles. The most common health problem stemming from shingles is postherpetic neuralgia . PHN occurs when nerves become damaged by the shingles virus, causing lingering pain in the affected area for months to years. Approximately 15% of people who have shingles develop PHN, and it is more likely to have PHN if you are an adult over 40.
More Information On Side Effects
Reactions listed under possible side effects or adverse events on vaccine product information sheets may not all be directly linked to the vaccine. See Vaccine side effects and adverse reactions for more information on why this is the case.
If you are concerned about any reactions that occur after vaccination, consult your doctor. In the UK you can report suspected vaccine side effects to the Medicines and Healthcare products Regulatory Agency through the Yellow Card Scheme . See more information on the Yellow Card scheme and monitoring of vaccine safety.

What Is Causing The Shingles Epidemic
While there has been a rise in cases of shingles, despite what you will read on most anti-vax websites, it is not because of the chickenpox vaccine .
In fact, it has been shown that:
- The trend in rising shingles cases in adults began before we even started giving kids the chickenpox vaccine in the United States
- The trend in rising shingles cases in adults did not continue to increase after we started giving kids the chickenpox vaccine in the United States
- The trend in rising shingles cases in adults also exists in other countries that do not routinely give kids the chickenpox vaccine
Whatever the reason for the trend in rising shingles cases in adults, it isn’t because more kids are protected from chickenpox now.
Can You Get Shingles After Being Vaccinated
Shingles is a viral infection. It presents with a rash followed by an episode of intense pain in the infected area. This is caused by the virus called varicella zoster. This virus also causes chickenpox. If a child has had chickenpox, the virus may not completely go away, lie dormant in the body and come back years later as shingles. Older individuals and immunocompromised individuals are more likely to develop shingles. The shingles vaccine is generally recommended for those older than 50 years of age and immunocompromised individuals .
The United States Food and Drug Administration has approved two vaccines to effectively prevent shingles: Zostavax and Shingrix. Shingrix provides strong protection against shingles and postherpetic neuralgia . Two doses of Shingrix are more than 90 percent effective at preventing shingles and postherpetic neuralgia. The vaccine is more than 85 percent effective for at least the first four years after vaccination. It is possible to get shingles after being vaccinated since no vaccine is 100 percent effective. However, the vaccine can considerably reduce the risk and intensity of shingles episodes.

What Is The Brand Name Of The Shingles Vaccine
There are 2 shingles vaccines used in the UK:
- Zostavax, a live vaccine given as 1 dose
- Shingrix, a non-live vaccine given as 2 doses, 2 months apart
Most people will have the Zostavax vaccine. The Shingrix vaccine is recommended if Zostavax is not suitable for you, for example if you have a condition that affects your immune system.

Why You Cant Get Shingles But You Can Still Get Chickenpox
Shingles are a reactivation of the same virus that caused chickenpox. Therefore, you need to have had exposure to VZV earlier in life.
Chickenpox tends to be more prevalent in children and is transmitted very quickly through groups. Even so, its still a real risk for adults. Chickenpox is a highly infectious disease that can spread to about 90 percent of unvaccinated household contacts of a person who has it.

Who Should Not Get The Shingles Vaccine
Some people shouldnt get the shingles vaccine. These people include those:
- Who currently have shingles.
- Who have had a severe allergic reaction to the shingles vaccine in the past.
- Who have tested negative for immunity to the varicella-zoster virus, meaning youve never had chickenpox. If youve never had chickenpox, you should get the chickenpox vaccine.
- Who are ill. You should wait until your illness has passed before receiving the shingles vaccine.
- Who are pregnant or breastfeeding.
How Is The Shingles Vaccine Made
The shingles vaccine available in the U.S., Shingrix®, contains a single protein from the surface of herpes zoster virus as well as two adjuvants: QS21 and monophosphoryl lipid A. QS21 is a soap-based molecule isolated from the bark of the Quillaja saponaria tree. Monophosphoryl lipid A is a detoxified form of lipopolysaccharide, a potent adjuvant taken from the surface of common bacteria.
The first shingles vaccine, called Zostavax®, is no longer available in the U.S. However, this version contained a more concentrated version of the same live, weakened virus as the current chickenpox vaccine. It contained about 14 times the amount of weakened chickenpox virus than the vaccine for children. This amount of virus was necessary to obtain a protective response in the aging immune systems of older adults. The introduction of Shingrix vaccine was important because adjuvants in the vaccine improved immune responses in older adults and decreased the need to use large quantities of the live, weakened virus also necessary to make chickenpox vaccine. For these two reasons Zostavax is no longer available in the U.S.

What Are The Side Effects
Shingrix can make the area where you get the shot swell or feel sore. Other effects include:
- Many people who get the vaccine have muscle aches, headaches, or feel tired.
- About 1 in 4 people have a fever or an upset stomach.
Younger people are more likely to have these side effects, and they typically last 2 or 3 days.
Itâs also possible to have an allergic reaction to an ingredient in the vaccine. If you have problems breathing, feel your face or throat swelling, or feel weak or dizzy after the shot, call 911 and get medical help right away.
How You Get Shingles
You dont catch shingles. Chickenpox virus caught earlier in your life reactivates later to cause shingles. You cant catch shingles from someone who has chickenpox.
However, if you have shingles blisters, the virus in the fluid can infect someone who has not had chickenpox and they may develop chickenpox.

Shingles Disease And How To Protect Against It
Shingles, or herpes zoster, is a painful skin rash that develops on one side of the face or body. It is caused by the varicella-zoster virus , the same virus that causes chickenpox. Anyone who has had chickenpox in the past can get shingles because VZV remains in the body after a person recovers from chickenpox. VZV can reactivate many years later, causing shingles.
Shingles is more common in older adults, people who have medical conditions that weaken the immune system, and people who take medications that suppress their immune systems. Getting vaccinated is the best way to prevent shingles.
Administration With Other Vaccines
CDC general recommendations advise that recombinant and adjuvanted vaccines, such as Shingrix, can be administered concomitantly, at different anatomic sites, with other adult vaccines, including COVID-19 vaccines. Concomitant administration of Shingrix with Fluarix Quadrivalent , 23-valent pneumococcal polysaccharide vaccine and Tetanus Toxoid, Reduced Diphtheria Toxoid and Acellular Pertussis Vaccine, Adsorbed , and 13-valent pneumococcal conjugate vaccine has been studied, and there was no evidence for interference in the immune response to either vaccine or safety concerns. Coadministration of Shingrix with adjuvanted influenza vaccine and COVID-19 vaccines is being studied.
Shingrix and pneumococcal vaccine can be administered at the same visit if the person is eligible for both. When both pneumococcal conjugate vaccine PCV13 and PPSV23 are recommended for an adult, PCV13 should always be administered first and can be administered concomitantly with Shingrix.

Shingles Vaccine And Insurance
Private health insurance plans often cover vaccination costs. Still, a patient might have a charge depending on the specific insurance plan.
Medicaid may or may not cover the vaccine cost.Medicare Part D plans cover the shingles vaccine, but there may be a cost to the patient depending on the plan. Usually, the fees are less than $50 per dose.
Medicare Part B does not cover the shingles vaccine.
Are There Complications Of Shingles
As we mentioned earlier, shingles is rarely deadly, but you can experience more than just a skin rash. Over 10 percent of people who get shingles suffer from postherpetic neuralgia, lasting nerve pain in previously infected areas. Postherpetic neuralgia can last for months or years and become quite severe.

Who Is At Risk For Developing Shingles
For most people, the chickenpox virus remains in the body quietly and doesnt cause any other problems. Researchers are not entirely sure why the virus gets reactivated in some individuals. They have noticed a correlation between stress and shingles outbreaks.
Obviously, individuals who have previously had the chickenpox are at risk for shingles. Of those individuals, those with an increased risk include people:
- With a weakened immune system
- Over the age of 50
- Who have been ill
- Who are under stress
What Are The Risks Of Shingles
About one in five people who get shingles will have severe pain after the rash goes away. This pain can last months or even years. This pain is known as post-herpetic neuralgia.
Rare complications of shingles include scarring, pneumonia, loss of hearing or vision, swelling of the brain and bacterial superinfections of the rash.

Who Should Not Get Shingrix
You should not get Shingrix if you:
- Have ever had a severe allergic reaction to any component of the vaccine or after a dose of Shingrix.
- Currently have shingles.
- Currently are pregnant. Women who are pregnant should wait to get Shingrix.
If you have a minor illness, such as a cold, you may get Shingrix. But if you have a moderate or severe illness, with or without fever, you should usually wait until you recover before getting the vaccine.
Shingles Virus Can Sleep Reactivate
Shingles is caused by the same virus the varicella zoster virus that causes chickenpox. Once you have had chickenpox, the virus that caused it remains inside your nerves. It is inactive, but it can be reactivated later in life. This causes shingles.
When the virus reactivates, the infected nerves, and the skin the nerves go to, become inflamed, causing a burning or stabbing pain. A few days later, when the virus reaches the skin, a rash of blisters appear along the affected nerve. The skin may be very sensitive, unable to tolerate even the lightest touch.
About 1 in 10 adults who get shingles experience long-term pain, even after the rash has healed completely. This condition is called post-herpetic neuralgia . It may last for months, or even years. And it can be debilitating.
After causing shingles, the virus again goes “back to sleep” inside your nerves. But it can still flare up again.

A Closer Look At The Safety Data
Both Shingrix and Zostavax shingles vaccines have been shown to be safe and well tolerated. Common side effects, such as soreness and redness at the injection site, are usually mild to moderate in intensity and resolve quickly on their own.
Shingrix
In 8 clinical trials of more than 10,000 participants:
- Grade 3 reactions were common after patients received Shingrix.
- About 1 out of 10 adults who received Shingrix reported grade 3 injection-site symptoms such as pain, redness, and swelling.
- About 1 out of 10 reported grade 3 systemic reactions such as myalgia , fatigue , headache, shivering, fever, and gastrointestinal illness.
- Most people who got Shingrix reported at least some pain at the injection site.
Zostavax
- A 2013 study showed that patients with a history of a previous shingles rash had the same side effects after Zostavax as those with no history of shingles. See Safety of zoster vaccine in elderly adults following documented herpes zoster.
How Much Does The Shingles Vaccine Cost
Shingles vaccines are not publicly funded in B.C. One dose of Zostavax costs about $200 each dose of Shingrix is about $150. Both vaccines are available at most travel clinics and pharmacies. Check with your health insurance provider to see if your plan covers the cost of these vaccines.Get immunized against shingles by making an appointment with your doctor, pharmacist or travel clinic.

Getting Vaccinated Against Chickenpox And Shingles
Vaccination is available for the prevention of both chickenpox and shingles.
Most insurance plans cover the cost of both vaccines. Medicare Part D and Medicaid may pay for at least part of the cost of shingles vaccination.
If you do not have health insurance or cannot afford vaccination, check for vaccine assistance programs directly with the shingles vaccine manufacturer, GlaxoSmithKline. For chickenpox, contact the Vaccines for Children program to see if you are eligible for help.
What Vaccines Can Help Prevent Shingles
There is currently one vaccine available in the U.S. to prevent shingles. Shingrix was approved in 2017 and it is more than 90% effective in preventing shingles. With Shingrix, you get two shots between 2 and 6 months apart and protection lasts an estimated 4-5 years. Doctors recommend it for healthy people over 50 as well as those 19 years of age and older who are or will be immunodeficient or immunosuppressed due to disease or therapy..
An earlier vaccine called Zostavax was removed from the market in 2020. That vaccine used a weak form of the chickenpox virus to send your bodyâs immune system into action to fight the disease. Shingrix does not. If you received the Zostavax vaccine, it is recommended that you also receive Shingrix.

Who Needs Shingles Vaccine
Asked by: Miss Cecilia Bode DVM
CDC recommends that healthy adults 50 years and older get two doses of the shingles vaccine called Shingrix , separated by 2 to 6 months, to prevent shingles and the complications from the disease. Your doctor or pharmacist can give you Shingrix as a shot in your upper arm.
Shingles And Contagious Transmission
Chickenpox is highly contagious. A person with the infection can easily pass it on to another person via direct contact or through the air.
If you have shingles, however, you cannot give it to another person. Instead, you can transmit the varicella-zoster virus to someone, and they can develop chickenpox if they are not immune to it.
When shingles develops into open blisters, the fluid inside the blisters contains the infectious virus.
Because of this, anyone who comes into direct contact with these blisters or inhales infected droplets can contract the virus if they are not immune to chickenpox. However, the rates of transmission are low.
Experts say that the virus cannot spread when the rash crusts. The risk of spreading also reduces when you cover the rash properly and wash your hands well.
