When Should I See A Doctor Because Of The Side Effects I Experience From Shingrix
Shingrix causes a strong response in your immune system, so it may produce short-term side effects. These side effects can be uncomfortable, but they are expected and usually go away on their own in 2 or 3 days. You may choose to take over-the-counter pain medicine such as ibuprofen or acetaminophen. Contact your healthcare provider if the symptoms are not improving or if they are getting worse.
In clinical trials, Shingrix was not associated with serious adverse events. In fact, serious side effects from vaccines are extremely rare. For example, for every 1 million doses of a vaccine given, only one or two people might have a severe allergic reaction. Signs of an allergic reaction happen within minutes or hours after vaccination and include hives, swelling of the face and throat, difficulty breathing, a fast heartbeat, dizziness, or weakness. If you experience these or any other life-threatening symptoms, see a doctor right away.
Can You Get Shingles If You Havent Had Chickenpox
No. You cant get shingles if youve never had chickenpox, but you can get chickenpox from someone who has shingles. If youve never had chickenpox and you come into direct contact with the oozing, blister-like rash of someone with shingles, the varicella-zoster virus can infect you and you would develop chickenpox.
Once youve had chickenpox, you could develop shingles at some point in your life. This is because the varicella-zoster virus never fully goes away after youve had chickenpox. It lies quietly inactive in your nerve tissue. Later in life, the virus may become active again and appears as shingles.
Can you get chickenpox more than once?
Its rare to get chickenpox twice in your life. Once youve had chickenpox, youre usually immune to it for the rest of your life. However, its not totally impossible. If you have a severely weakened immune system , you can get chickenpox a second time. If youve had chickenpox, you are more likely to get shingles at some point in your life than a repeat bout of chickenpox.
How Can I Protect My Child
The best way to protect your child from chickenpox is vaccination. If your child is not yet vaccinated and comes in contact with another child or family member who has chickenpox, they may still be protected if they are vaccinated right away.
If your child has an immune system disorder and comes in contact with chickenpox, call your doctor right away. The doctor can give a special type of immune globulin with a large concentration of antibodies to chickenpox to help prevent infection, or early treatment with an antiviral drug.

If You’ve Recently Had Covid Look Out For Shingles
16 August 2022
Opinion: Can having Covid trigger shingles? Yes, probably, according to Associate Professor Helen Petousis-Harris, and you might want to think about a shingles vaccine.
There is growing evidence, both anecdotal and now in several studies, that shingles seems to be occurring at a greater rate in people shortly after Covid-19 infection than might otherwise be expected.
A large recent study in the US looked at people who had not received Covid or shingles vaccines and found that people who had had Covid were 15 percent more likely to develop shingles than the people who hadnt. People who had been hospitalised for Covid were 20 percent more likely to develop shingles than people who hadnt been infected with the virus.
Why might this be? Shingles is very common. There are an estimated 20,000 cases each year in New Zealand about 55 new cases a day, so we would expect some cases to occur following a Covid-19 infection simply by chance. But investigations do suggest this involves more than chance and that there is a causal connection between Covid and shingles.
Shingles is caused by the reactivation of the varicella zoster virus that causes chickenpox. After recovery from the pox, the virus enters the nervous system and remains dormant, usually kept at bay very effectively by your immune system your T-cells in particular.
Why would Covid increase your risk of shingles?
Who Should Be Vaccinated With Shingrix
The Shingrix vaccine is recommended for those 50 years of age and older who are in good health.
You should get the Shingrix vaccine even if:
- Youve had shingles already.
- Youve been previously vaccinated with Zostavax . If youve been vaccinated with Zostavax, wait at least eight weeks before getting vaccinated with Shingrix.
- You dont know for sure if youve ever had chickenpox.
Ask your healthcare provider, who knows your entire health history if getting this vaccine is right for you.

Why Doesnt Having Chickenpox Earlier In Life Provide Immunity Against Having Shingles Later
After having chickenpox, your body doesnt rid your system of the virus. Instead, the virus stays in a portion of the spinal nerve root called the dorsal root ganglion. In most people, the virus simply stays there quietly and doesnt cause problems. Scientists arent always sure why the virus gets active again, but they know stress can be a cause.
Vaccinate To Decrease Your Shingles Risk
Your chances of getting shingles increase as you get older. The U.S. Centers for Disease Control and Prevention recommends that adults age 50 and older get vaccinated against shingles.
Two vaccines, recombinant zoster vaccine and zoster vaccine live are available in the United States to prevent shingles. Shingrix is the preferred vaccine.
The CDC recommends Shingrix for adults 50 years and older, whether or not they have already had shingles or previously received the Zostavaxvaccine, which has been used since 2006. You should get two doses of Shingrix, two to six months apart. Two doses of Shingrix are more than 90% effective at preventing shingles. Shingrix is also 90% effective in helping to prevent PHN in those who get shingles despite being vaccinated.
While Zostavax is still available, studies show it is less effective than Shingrix.Zostavax may be used in some healthy adults 60 years and older, for example, in those who are allergic to Shingrix.
There is no specific time that you must wait after having shingles before receiving the shingles vaccine. But its probably best to hold off until the shingles rash has disappeared before getting vaccinated.

What Should I Do About An Exposure To Varicella
If you have been in contact with someone with chickenpox or shingles, or if you have a rash-associated illness that might be chickenpox or shingles, discuss your situation with your healthcare provider. Blood tests may be done to see if you have become infected with the virus or have had the disease in the past. If you are pregnant and not immune and have been exposed to chickenpox or shingles, call your healthcare provider immediately. Your provider may choose to treat you with a medication called varicella-zoster immune globulin , but in order for this medication to be most helpful, it needs to be given as soon as possible after your exposure to varicella.
Whats The Treatment For Chickenpox
If youre worried that you or your child has chickenpox, call your doctor. If its not a serious case, theyll probably recommend treating the symptoms while waiting for the disease to run its course. Treatment suggestions might include:
- Nonaspirin pain medication like acetaminophen can relieve fever.
- Over-the-counter topical lotions such as calamine lotion can relieve itching.
Children and anyone under the age of 18 should never take aspirin for an illness. This is because of the risk of a rare, but fatal, condition called Reyes syndrome.
If your doctor feels that you or your child are likely to develop a more serious case, they may recommend an antiviral medication such as acyclovir .

How Long Between Shingles Attack And Recurrence
The time between an initial shingles case and its relapse can vary a great deal, and there is no established figure. However, researchers have noted most of these flare-ups arise in the four- to eight-year window following an initial attack. Recurrence within three years is much rarer.
Factors such as overall health status and the presence of other diseases can spur attacks, and there are preventative medications and approaches.
What Is The Most Painful Stage Of Shingles
Typically, the peak pain of shingles is felt within 4 or 5 days after the first symptoms develop, and it comes along with a blistering rash. As the blisters scab over, the pain usually starts to disappear. In some cases, the pain does not go away. This is known as a condition called postherpetic neuralgia.

What Everyone Should Know About The Shingles Vaccine
CDC recommends that adults 50 years and older get two doses of the shingles vaccine called Shingrix to prevent shingles and the complications from the disease. Adults 19 years and older who have weakened immune systems because of disease or therapy should also get two doses of Shingrix, as they have a higher risk of getting shingles and related complications.
Your doctor or pharmacist can give you Shingrix as a shot in your upper arm.
Shingrix provides strong protection against shingles and PHN. In adults 50 years and older who have healthy immune systems, Shingrix is more than 90% effective at preventing shingles and PHN. Immunity stays strong for at least the first 7 years after vaccination. In adults with weakened immune systems, studies show that Shingrix is 68%-91% effective in preventing shingles, depending on the condition that affects the immune system.
Can You Get Chickenpox If You’ve Been Vaccinated
Yes. About 15% 20% of people who have received one dose of varicella vaccine do still get chickenpox if they are exposed, but their disease is usually mild. Vaccinated persons who get chickenpox generally have fewer than 50 spots or bumps, which may resemble bug bites more than typical, fluid-filled chickenpox blisters. In 2006, the Advisory Committee on Immunization Practices voted to recommend routine two-dose varicella vaccination for children. In one study, children who received two doses of varicella vaccine were three times less likely to get chickenpox than individuals who have had only one dose.

What Are The Symptoms
- Chickenpox begins with a fever, aches and pains.
- Within 1 or 2 days your child will get a rash. The rash is usually itchy and can make your child uncomfortable. It appears on the scalp and face, spreading quickly down the body and onto the arms and legs. The spots start as flat pink spots that turn into small water blisters. New spots will form even after others turn into blisters. Some children only get a few blisters, but others can have as many as 500. Blisters open, dry up and form scabs in 4 or 5 days.
- Most children lose their appetite and have a headache during the first few days.
Am I At Risk For Shingles
Everyone who has had chickenpox is at risk for developing shingles. Researchers do not fully understand what makes the virus become active and cause shingles. But some things make it more likely:
- Older age. The risk of developing shingles increases as you age. About half of all shingles cases are in adults age 60 or older. The chance of getting shingles becomes much greater by age 70.
- Trouble fighting infections. Your immune system is the part of your body that responds to infections. Age can affect your immune system. So can HIV, cancer, cancer treatments, too much sun, and organ transplant drugs. Even stress or a cold can weaken your immune system for a short time. These all can put you at risk for shingles.
Most people only have shingles one time. However, it is possible to have it more than once.

Does The Vaccine Help Prevent It
The CDC suggests getting the shingles vaccine Shingrix if you’re a healthy adult ages 50 or older, or if you are19 years of age and older and are or will be immunodeficient or immunosuppressed due to disease or therapy.. It was approved in 2017 and has been found to be more than 90% effective in preventing shingles and the complications caused by the disease. Even if you’ve already had shingles, the CDC says the vaccine can help prevent a second round of it. Shingrix is preferred over an earlier vaccine, Zostavax, which was removed from the market in 2020. You should also get it if you previously had the Zostavax vaccine.
Shingrix is also approved for those 18 years or older who may be immunodeficient or immunosuppressedbecause of an illness or treatment.
Talk to your doctor about when to get the vaccine. If you’ve just gotten over shingles, the CDC recommends waiting at least until the shingles rash has disappeared.
You should not get the Shingrix vaccine if you:
- Are pregnant or nursing
- Are allergic to the vaccine
- You tested negative for immunity to chickenpox if so, you should ask about the chickenpox vaccine.
Who Should Not Be Vaccinated With Shingrix
You shouldnt receive the Shingrix vaccine if you:
- Have ever had a severe allergy to this vaccine or any ingredient in this vaccine.
- Are breastfeeding or pregnant.
- Currently have shingles.
- Are ill and have a high fever.
- Have tested negative for immunity to varicella-zoster virus .
Ask your healthcare provider if the benefits of getting the vaccine outweigh any potential risks.

What Illnesses Does Varicella
Chickenpox first occurs as a blister-like skin rash and fever. It takes from 10-21 days after exposure for someone to develop chickenpox. The sores commonly occur in batches with different stages present at the same time. The blisters usually scab over in 5 days. A person with chickenpox is contagious 1-2 days before the rash appears and until all blisters have formed scabs. Children with weakened immune systems may have blisters occurring for a prolonged time period. Adults can develop severe pneumonia and other serious complications.
Shingles occurs when the virus, which has been inactive for some time, becomes active again. Severe pain and numbness along nerve pathways, commonly on the trunk or on the face, are present. Clusters of blisters appear 1 to 5 days later. The blisters are usually on one side of the body and closer together than in chickenpox. Shingles does not spread as shingles from one person to another. If people who have never had chickenpox come in contact with the fluid from shingles blisters, they can develop chickenpox.
Where Does Shingles Come From
When you have chickenpox as a child, your body fights off the varicella-zoster virus and the physical signs of chickenpox fade away, but the virus always remains in your body. In adulthood, sometimes the virus becomes active again. This time, the varicella-zoster virus makes its second appearance in the form of shingles.

What Are The Risk Factors For Recurring Shingles
People dont know what causes recurring shingles, but certain factors increase your chances of getting shingles again.
People with weakened immune systems are more likely to get shingles again. One study determined that the rate of shingles recurrence was among people with compromised immune systems. This is about 2.4 times higher than for those who didnt have compromised immune systems.
You may have a compromised immune system if you:
- are getting chemotherapy or radiation therapy
- have organ transplants
- are taking high doses of corticosteroids like prednisone
Additional risk factors include:
- longer-lasting and more severe pain with the first case of shingles
- pain for 30 days or more with the first case of shingles
- being over the age of 50
Having one or more blood relatives with shingles may also increase your risk of getting shingles.
How Well Does Shingrix Work
Two doses of Shingrix provide strong protection against shingles and postherpetic neuralgia , the most common complication of shingles.
- In adults 50 to 69 years old with healthy immune systems, Shingrix was 97% effective in preventing shingles in adults 70 years and older, Shingrix was 91% effective.
- In adults 50 years and older, Shingrix was 91% effective in preventing PHN in adults 70 years and older, Shingrix was 89% effective.
- In adults with weakened immune systems, Shingrix was between 68% and 91% effective in preventing shingles, depending on their underlying immunocompromising condition.
In people 70 years and older who had healthy immune systems, Shingrix immunity remained high throughout 7 years following vaccination.

How Long Do Shingles Spots Keep Appearing
Skin sensitivity, tingling, itching, and/or pain in the area of the skin before the rash appears. Rash, which typically appears after 1 to 5 days once symptoms begin and initially looks like small, red spots that turn into blisters. Blisters typically scab over in 7 to 10 days and clear up within 2 to 4 weeks.
When Should I See A Doctor
See your doctor at the first sign of shingles. Getting treated early can help it go away faster and may help you avoid related problems. For instance, shingles on the face can cause hearing or sight problems, including blindness.
If you have a weak immune system and can’t get the vaccine, early treatment is your best defense against shingles.
Sometimes what seems to be shingles is really herpes simplex. Though it usually appears as “cold sores” around the mouth or genitals, this form of herpes can show up elsewhere. A different treatment is used to clear it up. Your doctor can do tests, such as a viral culture, to confirm whether you have shingles and to get you the right treatment.
