Shingles Vaccine Shingrix Gets Fda Approval For Prevention In Immunocompromised Adults
GlaxoSmithKline today announced that the US Food and Drug Administration has approved Shingrix for the prevention of shingles in adults aged 18 years and older who are or who will be at increased risk of shingles due to immunodeficiency or immunosuppression caused by known disease or therapy. Immunocompromised individuals are at greater risk of shingles and associated complications than immunocompetent individuals.
Shingrix, a non-live, recombinant sub-unit adjuvanted vaccine, given intramuscularly in two doses, was initially approved by FDA in 2017 for the prevention of shingles in adults 50 years of age or older. Shingrix is not indicated for prevention of primary varicella infection . The approval for this new population expands the number of people who can be protected against shingles by Shingrix.
Were proud to offer Shingrix in the US for the prevention of shingles in those who are immunocompromised, with FDA granting a broad indication for use in adults at increased risk of this disease, said Thomas Breuer, Chief Medical Officer, GSK Vaccines. Older age and being immunocompromised are the most common risk factors for shingles disease. GSK is committed to this important patient population at increased risk for shingles disease and its complications by bringing them a vaccine option that can help prevent this painful condition.
Administering And Storing Shingrix
- Adults 50 years and older should receive 2 doses of Shingrix. Give the second dose 2 to 6 months after the first.
- Administer Shingrix intramuscularly in the deltoid region of the upper arm with a 1- to 1.5-inch needle.
- Both vials of Shingrix must be refrigerated at a temperature of 36-46° F. Do not use if exposed to temperatures below 36° F.
Live Shingles Vaccine Vs Non
A live vaccine is one that contains a weakened form of a germ. Shingrix is not a live vaccine. Its an inactive vaccine, which is a vaccine thats made from a germ thats been killed.
Because Shingrix is inactive, more people can receive it. This includes people with a weakened immune system .
Zostavax was a shingles vaccine that was live.
People with weakened immune systems are typically advised against receiving live vaccines. This is because on very rare occasions, live vaccines can mutate back to the full-strength germ that causes a disease. If this happens, people with weakened immune systems would have a much higher risk for developing the disease that the vaccine is meant to prevent.

Who Shouldnt Get The Shingles Vaccine
There are a few situations in which shingles vaccination may not be right for you. You should not get Shingrix if youâve ever had a severe reaction to a vaccine. This means you had trouble breathing or swelling in your mouth or airway, a life-threatening condition called anaphylaxis.
You should also skip Shingrix if:
- You have allergies to any parts of the vaccine. These include gelatin and the antibiotic neomycin. If you have other allergies, tell your doctor or pharmacist about them before you get Shingrix.
- You currently have shingles or another illness. You can get the vaccine when youâre well.
- You are pregnant or breastfeeding. You should wait until youâve stopped breastfeeding to get vaccinated.
- You happened to test negative for VZV, the virus that causes chickenpox. If youâre older than 50, you probably had chickenpox even if you donât remember it. The CDC does not recommend testing for this. However, if a blood test shows youâve never had the childhood illness, you should get the chickenpox vaccine instead.
If you have a disease or take medications that affect your immune system, talk to your doctor about the pros and cons of Shingrix.
âItâs an individualized decision based on factors such as the specific medications and conditions of the person sitting in front of you,â Kistler says. She often consults with her patientsâ specialist doctors to make decisions about Shingrix.
Gsks New Shingles Vaccine May Win Nod Over Mercks Zostavax
We are absolutely thrilled to get to this point because the science behind this vaccine offers tremendous potential for helping patients, protecting them against getting shingles and its complications, said Dr. Leonard Friedland, vice president for scientific affairs and public health for GSKs North American vaccines unit.
Shingles is a delayed complication of chickenpox, a highly infectious disease most children suffered through in the era before the chickenpox vaccine was developed.
People who have had chickenpox harbor the varicella zoster virus the bug that causes the disease in their bodies after infection.
Healthy immune systems keep the virus in a dormant state. But people who have weakened immune systems, either because of an illness or because the immune system declines with age, can develop shingles.
The condition typically manifests as a painful, itchy rash, either on one side of the torso or one side of the face. The blisters can lead to ulcers and scars.
Theres nothing good about shingles, said Dr. Anne Louise Oaklander, a shingles expert who is director of the nerve unit at Massachusetts General Hospital.
And it can be quite bad. In the worst cases, people may not be able to put their clothing on. And it can leave ulcers and scars.
Shingles can also lead to strokes, vision and hearing loss, and other complications, Oaklander said.

Fda Approves New Shingles Vaccine
A new, more effective shingles vaccine has been approved by the U.S. Food and Drug Administration.
The new vaccine from GlaxoSmithKline will be the second shingles vaccine available in the U.S. market. The other is from Merck and was introduced in 2006, the Associated Press reported.
Shingles is a painful condition caused by the chickenpox virus. Anyone who’s had chickenpox carries the virus that causes shingles.
A study funded by Glaxo found that the company’s Shingrix vaccine prevented shingles in about 90 percent of people. Merck’s Zostavax vaccine is about 50 percent effective, the AP reported.
Shingrix will cost $280 for the required two shots. Zostavax costs $223. Most insurance plans cover the vaccination.
Both vaccines are for adults 50 and older, but the Centers for Disease Control and Prevention recommends vaccination for people 60 and older, partly because vaccination loses effectiveness over time, the AP reported.
How Safe Is Shingrix
studies showed that Shingrix was safe and effective.
There have been concerns about ingredients, such as thimerosal, that may be added to vaccines. Thimerosal is a kind of preservative that contains mercury. Its added then taken out of some vaccines to keep other germs and bacteria from growing. The concern arose when early research connected thimerosal to autism. This link has since been found to be false. Shingrix doesnt contain thimerosal.

How Cdc Monitors Vaccine Safety
CDC and FDA monitor the safety of vaccines after they are approved or authorized. If a problem is found with a vaccine, CDC and FDA will inform health officials, health care providers, and the public.
CDC uses 3 systems to monitor vaccine safety:
- The Vaccine Adverse Event Reporting System : an early warning system, co-managed by CDC and FDA, to monitor for potential vaccine safety problems. Anyone can report possible vaccine side effects to VAERS.
- The Vaccine Safety Datalink : a collaboration between CDC and 9 health care organizations that conducts vaccine safety monitoring and research.
- The Clinical Immunization Safety Assessment Project: a partnership between CDC and several medical research centers that provides expert consultation and conducts clinical research on vaccine-associated health risks.
How Do Vaccines Work
This article is part of a series of explainers on vaccine development and distribution. Learn more about vaccines from how they work and how theyre made to ensuring safety and equitable access in WHOs Vaccines Explained series.
Germs are all around us, both in our environment and in our bodies. When a person is susceptible and they encounter a harmful organism, it can lead to disease and death.
The body has many ways of defending itself against pathogens . Skin, mucus, and cilia all work as physical barriers to prevent pathogensfrom entering the body in the first place.
When a pathogen does infect the body, our bodys defences, called the immune system, are triggered and the pathogen is attacked and destroyed or overcome.

Can I Get Shingrix If Ive Never Had Chickenpox
If youve never had chickenpox , the CDC recommends that you get the chickenpox vaccine instead of Shingrix. Researchers havent studied Shingrix in people who have never had chickenpox. And Shingrix is not approved for preventing chickenpox.
If you cant recall whether youve had chickenpox, you may need to be screened for it. But this will depend on your age.
Its assumed that people born in the United States and elsewhere before 1980 have been exposed to chickenpox. Therefore, you may be able to receive Shingrix. You should check with your doctor first to make sure.
Can Shingrix Cause A Rash
Its unlikely that a Shingrix injection will cause a rash. But note that an injection site reaction is different from a shingles rash.
A shingles rash, which is caused by shingles itself, is often painful. It commonly appears as blisters around the torso, neck, or face.
People who received Shingrix in didnt report shingles-like rashes.
The Food and Drug Administration approves vaccines such as Shingrix to prevent certain conditions.

Fda Approves Shingrix Vaccine For Immunocompromised Patients
The newest FDA indication allows for greater distribution to younger but equally vulnerable immunocompromised patients.
The US Food and Drug Administration approved the non-live, recombinant sub-unit adjuvanted vaccine Shingrix for the prevention of shingles in adults aged 18 years and older with increased risk of immunodeficiency or immunosuppression.
The GlaxoSmithKline vaccine, which is given intramuscularly to patients through 2 doses, was originally approved by the FDA in 2017 for the prevention of shingles in adults 50 years or older. The newest indication by the FDA is set to expand upon the number of patients who can be protected against shingles.
Were proud to offer Shingrix in the US for the prevention of shingles in those who are immunocompromised, with FDA granting a broad indication for use in adults at increased risk of this disease, said Thomas Breuer, Chief Medical Officer, GSK Vaccines, in a recent statement by the company.
Breuer mentioned that in addition to old age, being immunocompromised is among the most common of risk factors for shingles, and that GSK is committed to aiding this vulnerable group with the Shingrix vaccine.
According to a report by Avalere Health, more than 17 million doses of recommended vaccines were missed by adults during the ongoing COVID-19 pandemic. However, more than 100 million adults 50 years and older received Shingrix prior to COVID-19.

The Body’s Natural Response
A pathogen is a bacterium, virus, parasite or fungus that can cause disease within the body. Each pathogen is made up of several subparts, usually unique to that specific pathogen and the disease it causes. The subpart of a pathogen that causes theformation of antibodies is called an antigen. The antibodies produced in response to the pathogens antigen are an important part of the immune system. You can consider antibodies as the soldiers in your bodys defense system. Eachantibody, or soldier, in our system is trained to recognize one specific antigen. We have thousands of different antibodies in our bodies. When the human body is exposed to an antigen for the first time, it takes time for the immune system torespond and produce antibodies specific to that antigen.
In the meantime, the person is susceptible to becoming ill.
This means that if the person is exposed to the dangerous pathogen in the future, their immune system will be able to respond immediately, protecting against disease.
Why Can’t You Get The Shingles Vaccine Before 50
Shingles is a painful belt-like patterned rash caused by varicella-zoster virus . Shingles is more common in adults over 50 years of age and in people with conditions that weaken the immune system.
The varicella-zoster virus is a type of herpesvirus. Other herpesviruses include the herpes simplex virus, which causes cold sores and genital herpes.
The shingles vaccine is available for adults 50 years and older to reduce the chance of developing shingles. Shingrix requires two doses administered two to six months apart. The two doses of Shingrix are more than 90% effective at preventing shingles and postherpetic neuralgia. Protection from the Shingrix shingles vaccine stays above 85% for at least four years after vaccination.
The Shingrix shingles vaccine is not approved by the Food and Drug Administration for use in people under 50 years of age. However, adults 19 years and older with weakened immune systems may also get two doses of shingles vaccine, due to a higher risk of getting shingles and related complications.
The vaccine has only been tested in adults 50 years and older and The Advisory Committee on Immunization Practices , a committee that is part of the Centers for Disease Control , does not recommend zoster vaccination for people younger than age 50 years regardless of their history of 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.
Who Is Getting The Vaccine
In this outbreak, the vaccine is being deployed to close contacts of individuals with confirmed monkeypox cases, Adalja tells Healthline.
The United Kingdom is currently offering vaccines, however not to the public. It is currently isolating those with confirmed infections and offering the vaccine to close contacts to help prevent the spread.
Schaffner tells Healthline that the makers of JYNNEOS are actively making the vaccine as many countries in Europe are likely reaching out to them for supply.
There are other manufacturers such as Tonix Pharmaceutical who are developing new ways to vaccinate the public against pox viruses, but currently, these vaccines are still in development.
Avoiding people with known monkeypox is the first step someone can take to avoid the virus. Similarly, if you know someone who has been potentially exposed, avoid close or intimate contact until the incubation period of up to three weeks has passed.
As with most bacteria and viruses, good hand hygiene after contact with infected animals or humans is important. This includes washing your hands with soap and warm water or using an alcohol-based hand sanitizer.
You can avoid contact with animals who may have been exposed to the virus or been found dead in areas where monkeypox is endemic. Additionally, avoid contact with any materials such as bedding, which has touched a sick animal with monkeypox.

Two Current Smallpox Vaccines Also Effective Against Monkeypox
ACAM2000 is a vaccine that was created for smallpox but also has some cross coverage with monkeypox. This vaccine is approved for people who are 18 and older and are at high risk for smallpox infection. For monkeypox, this same vaccine can be used in people exposed to monkeypox if used under an expanded access investigational new drug protocol, according to the
to prevent the spread of both monkeypox and smallpox.
This vaccine is approved to help prevent the viruses in adults 18 years and older who are at high risk for infection. It is administered as a two-dose regimen 4 weeks apart.
JYNNEOS is expected to be at least 85 percent or so effective at the prevention of monkeypox and more effective at the prevention of severe monkeypox, says Dr. Amesh Adalja, Senior Scholar at Johns Hopkins Center for Health Security.
Although not directly studied in pregnant human subjects, animal studies in rabbits show that this vaccine has no evidence of harm to a developing fetus. It is, however, unknown if this vaccine is safe for breastfeeding.
Fda Approves Gsks Shingrix To Prevent Shingles In Immunocompromised Adults
By Brian Buntz | July 26, 2021
GlaxoSmithKline received permission from FDA to expand the use of its Shingrinx shingles vaccine to include immunocompromised and immunosuppressed adults 18 years old or older.
Having won initial FDA approval in 2017 for individuals 50 and older, the shingles vaccine is a non-live, recombinant subunit adjuvanted vaccine. Shingrix is the first shingles vaccine to win an indication for people who are immunodeficient or immunosuppressed.
Approximately 1 million people develop shingles in the U.S. each year, according to the CDC.
GSK has gained shingles vaccine market share since November 2020, when Merck discontinued Zostavax, a rival shingles vaccine. Zostavax initially won approval in 2017 and was previously the only shingles vaccine available in the U.S.
The FDA decided based on clinical studies involving adults 18 or older who had undergone an autologous hematopoietic stem cell transplant . Additionally, it reviewed a posthoc analysis from vaccine recipients who had received treatment for hematological malignancies. The agency also reviewed safety and immunogenicity data in adults likely to be immunodeficient or immunosuppressed due to HIV, solid tumors or kidney transplants.
The COVID-19 pandemic has resulted in slowing shingles vaccination rates. A recent report from Avalere Health that received support from GSK concluded that the pandemic forced more adults to miss more than 17 million vaccine doses.
