A shingles vaccine is recommended for adults once they turn 50, and it can help prevent the rash and other complications associated with shingles.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Most people have been infected with the varicella-zoster virus if they\u2019ve ever had chickenpox. After chickenpox resolves, the varicella-zoster virus lies dormant in the body for years, if not forever. Later in life, the virus can reactivate as shingles and cause a painful rash that usually wraps around the face or torso.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Although Shingrix and Zostavax work in similar ways to prevent shingles, there are some important differences between the two.<\/span><\/p>\n<h2 id=\"drug-overview-differences\">What are the main differences between Shingrix and Zostavax?<\/h2>\n<p><span style=\"font-weight: 400;\">Shingrix <\/span><a href=\"https:\/\/www.singlecare.com\/prescription\/shingrix\/what-is\"><span style=\"font-weight: 400;\">(What is Shingrix?<\/span><\/a><span style=\"font-weight: 400;\">) is a recombinant, adjuvanted zoster vaccine that was first FDA-approved in 2017. It contains a certain protein called the varicella-zoster glycoprotein E (gE) antigen to produce an immune response in the body. Shingrix also contains an adjuvant, or added ingredient, to help boost the body\u2019s immune response to the virus. The adjuvant suspension in Shingrix contains an extract from the <\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC6337100\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">Quillaja saponaria tree<\/span><\/a><span style=\"font-weight: 400;\">, known to modulate immune activity. Because Shingrix is an inactivated or non-live vaccine, it can be used in immunocompromised patients or those with a weakened immune system.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Shingrix is administered as an injection into the muscle (intramuscular). It is given in two separate doses with a period of <\/span><a href=\"https:\/\/www.fda.gov\/media\/108597\/download\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">two to six months<\/span><\/a><span style=\"font-weight: 400;\"> between the first and second doses. The second dose is necessary to ensure long-term effectiveness. Immunocompromised or immunodeficient individuals may require a shorter vaccine schedule and can get the booster one to two months after the first shot.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Shingrix is currently the <\/span><a href=\"https:\/\/www.cdc.gov\/vaccinesafety\/vaccines\/shingles-herpes-vaccine.html\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">preferred shingles vaccine<\/span><\/a><span style=\"font-weight: 400;\">, according to the Centers for Disease Control and Prevention (CDC).\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Zostavax, approved in 2006, is a live, attenuated herpes zoster vaccine. In other words, Zostavax contains a weakened version of the actual virus to produce an immune response. For this reason, Zostavax is not recommended for those who are immunocompromised. Otherwise, the vaccine may cause a symptomatic infection, even weeks following vaccination.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Zostavax is administered as a single injection underneath the skin (subcutaneous).

It is administered in two doses, with two to six months between the first dose and second dose. Shingrix is manufactured by GlaxoSmithKline.\u00a0<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">What is Zostavax?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Zostavax is a live attenuated zoster vaccine that was FDA-approved in 2006. As a live attenuated vaccine, Zostavax contains a live, weakened version of the varicella-zoster virus. Zostavax is administered in a single dose in adults aged 50 years or older. It is manufactured by Merck. As of November 2020, Zostavax has been discontinued in the U.S.\u00a0<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Are Shingrix and Zostavax the same?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Both Shingrix and Zostavax can decrease the risk of shingles. However, they differ in effectiveness, administration, and side effects. Shingrix is a recombinant zoster vaccine and Zostavax is a live vaccine. Meaning, Shingrix contains an inactivated form of the varicella-zoster virus and Zostavax contains a live, weakened form of the virus. Another difference is that Shingrix is injected into the muscle while Zostavax is injected underneath the skin. Compared to Zostavax, Shingrix is a newer, more effective shingles vaccine.\u00a0<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Is Shingrix or Zostavax better?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Shingrix is more effective than Zostavax. Shingrix is 97% effective at preventing shingles in adults aged 50 to 69 years old, whereas Zostavax is only 70% effective at preventing shingles in the same age group. Shingrix consistently prevents shingles in older adults, while the effectiveness of Zostavax decreases with increasing age. However, Shingrix may cause more systemic side effects than Zostavax.\u00a0<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Can I use Shingrix or Zostavax while pregnant?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">The Centers for Disease Control and Prevention (CDC) does not recommend Shingrix or Zostavax in women who are pregnant. There are not enough studies to determine the <\/span><a href=\"https:\/\/www.cdc.gov\/vaccines\/vpd\/shingles\/hcp\/shingrix\/recommendations.html\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">safety of Shingrix<\/span><\/a><span style=\"font-weight: 400;\"> or <\/span><a href=\"https:\/\/www.cdc.gov\/vaccines\/vpd\/shingles\/public\/zostavax\/index.html\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">Zostavax in pregnant women<\/span><\/a><span style=\"font-weight: 400;\">. Consult your doctor or healthcare provider before getting a shingles vaccine.\u00a0<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Can I use Shingrix or Zostavax with alcohol?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Drinking alcohol does not alter the effectiveness of Shingrix or Zostavax. It is generally safe to drink in moderation after getting vaccinated with a shingles vaccine.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Does Shingrix require two shots?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Shingrix is approved as a two-dose vaccine. It is not recommended to skip the second dose of Shingrix. Typically, the second Shingrix dose is administered two to six months after the first dose in adults aged 50 years and older. However, in people who are immunocompromised, the second dose can be given one to two months after the first dose.\u00a0<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">What happens if you don&#8217;t get a second Shingrix shot?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">The second Shingrix shot is important to ensure complete protection with the vaccine. Skipping the second dose of Shingrix may lead to reduced protection from shingles. However, you don\u2019t need to worry if more than six months have passed before you receive the booster shot. Just make sure you receive the second shot as close to the two- to six-month timeframe as possible.\u00a0<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">How long does the Shingrix last?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Clinical trials have shown that Shingrix <\/span><a href=\"https:\/\/www.tandfonline.com\/doi\/full\/10.1080\/14760584.2018.1495565\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">remains effective for at least four years<\/span><\/a><span style=\"font-weight: 400;\"> after the second dose. It is suggested that Shingrix lasts even longer than that. Still, more studies are being conducted on the effectiveness of Shingrix in the long term.\u00a0<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Does Shingrix cause Guillain-Barr\u00e9 Syndrome?\u00a0<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Shingrix may be associated with an increased risk of Guillain-Barr\u00e9 syndrome, a rare nervous system disorder. The <\/span><a href=\"https:\/\/www.fda.gov\/vaccines-blood-biologics\/safety-availability-biologics\/fda-requires-warning-about-guillain-barre-syndrome-gbs-be-included-prescribing-information-shingrix\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">FDA required that the vaccine label be changed<\/span><\/a><span style=\"font-weight: 400;\"> to include this information and reflect the potential risk of Guillain-Barr\u00e9 syndrome. A postmarketing observational study found that there may be an increased risk of Guillain-Barr\u00e9 syndrome during the 42 days following vaccination. Still, the FDA asserts the benefits of the vaccine outweigh the potential risk of adverse effects.\u00a0<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">How long is Zostavax effective?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Protection from shingles lasts around <\/span><a href=\"https:\/\/www.cdc.gov\/vaccines\/vpd\/shingles\/public\/zostavax\/index.html\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">five years after vaccination with Zostavax<\/span><\/a><span style=\"font-weight: 400;\">. After five years, the effectiveness of Zostavax may decrease over time. The CDC recommends getting the new shingles vaccine, Shingrix, even if you have already received the Zostavax vaccine in the past.\u00a0<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Drug overview &amp; main differences | Conditions treated | Efficacy | Insurance coverage and cost comparison | Side effects | Drug interactions | Warnings | FAQ As of November 2020, Zostavax has been discontinued in the U.S. Additionally, in March 2021, the FDA approved a safety labeling change for Shingrix.
