Shingrix Shingles Vaccine Description
GSK's Shingrix is an adjuvanted recombinant zoster vaccine, consisting of the varicella-zoster virus glycoprotein E antigen and the AS01B adjuvant system, and a proprietary adjuvant containing QS-21 and MPL with liposomes.
Shingrix is the only shingles vaccine proven to be up to 90% effective in various clinical trials, says GSK. Shingles, also known as herpes zoster, is a painful skin rash caused by reactivation of the varicella-zoster virus the same virus that causes chickenpox.
Shingrix works to boost your body’s protection against shingles. Your immune system declines as you age, and that puts you at an increased risk for shingles. For those who are 50 years and older, Shingrix helps your immune system defend against shingles regardless of age.
Pain, redness, and swelling at the injection site, muscle pain, tiredness, headache, shivering, fever, and upset stomach are all common side effects of Shingrix.
There are two vaccines licensed in the USA and recommended by the Advisory Committee on Immunization Practices to prevent shingles. The Zoster vaccine live (ZVL, Zostavax) has been used since 2006. And, recombinant zoster vaccine (RZV, Shingrix) has been used since 2017, says the U.S. CDC.
May 22, 2020, Merck issued a letter stating it would no longer sell Zostavax in the USA, effective July 1, 2020. This decision is not related to any product safety or manufacturing issues, and only affects customers in the USA.
London, England based GlaxoSmithKline (GSK) is the producer of Shingrix, which produced about $2.2 billion in revenues during 2019.
The global shingles vaccine market is poised to grow by USD 1.08 billion during 2020-2024, progressing at a CAGR of over 7% during the forecast period.
Shingles is a painful rash that develops on the face or body. The rash consists of blisters that typically scab over in 7 to 10 days and fully clears up within 2 to 4 weeks. Before the rash appears, people often have pain, itching, or tingling in the area where it will develop. This may happen several days before the rash appears.
Most commonly, the rash occurs in a single stripe around either the left or the right side of the body. In other cases, the rash occurs on one side of the face. Shingles on the face can affect the eye and cause vision loss. In rare cases (usually in people with weakened immune systems), the rash may be more widespread on the body and look similar to a chickenpox rash.
Complications can arise with Shingles especially in older adults.
The most common complication of shingles is long-term nerve pain called postherpetic neuralgia (PHN).
PHN occurs in the areas where the shingles rash was, even after the rash clears up. It can last for months or years after the rash goes away. The pain from PHN can be so severe and debilitating that it interferes with daily life.
About 10 to 18% of people who get shingles will experience PHN. Your risk of PHN increases with age. An older adult with shingles is more likely to develop PHN and have longer-lasting and more severe pain than a younger person with shingles. People younger than 40 rarely experience PHN.
A study published on May 15, 2020, in ACR Open Rheumatology, showed that the vaccine did not prompt flares of rheumatoid conditions.
Shingrix Shingles Vaccine Indication
No matter how healthy you feel, your immune system declines as you age, and that puts you at an increased risk for shingles. Shingrix is a vaccine for the prevention of shingles (herpes zoster) in adults 50 years and older. If you’re one of the 99% of adults over 50 years old who have had chickenpox, the virus that causes shingles is inside your body and can reactivate at any time. 1 in every 3 people in the US will get shingles in their lifetime.
People should not receive Shingrix if they are allergic to any of its ingredients or had an allergic reaction to a previous dose of Shingrix. And, Shingrix was not studied in pregnant or nursing women. Tell your healthcare provider if you are pregnant, plan to become pregnant, or are breastfeeding, says GSK.
Shingrix is not used to prevent primary varicella infection (chickenpox).
Shingrix Shingles Vaccine Dosage
Shingrix is a suspension for intramuscular injection only. It is supplied in 2 vials (0.5 mL each) that must be combined prior to administration. Two doses are necessary to provide strong protection, up to 90%, the first dose at Month 0 followed by a second dose administered anytime between 2 and 6 months later.
The Shingrix vaccine series is administered as an injection into the muscle in the upper arm. It is important to complete the 2‑dose series to help prevent shingles.
The CDC has stated: If more than 6 months have elapsed since the 1st Shingrix dose, administer the 2nd dose as soon as possible. Do not restart the Shingrix vaccine series.
Shingrix Shingles Vaccine News
- August 5, 2020 - GSK launched a national campaign to help increase low rates of vaccination among older adults. The campaign, Brought to You By Vaccines, will educate adults ages 50 and older about the value of vaccines and the urgent need to talk to their healthcare provider or pharmacist about the recommended vaccines they need or may have recently missed. Since the declaration of the COVID-19 pandemic and public health measures to slow the spread of the disease in the US, ordering rates across adult vaccines among healthcare practices have dropped an average of 62 percent.
