Shingrix vs. Zostavax: Which Shingles Vaccine is Better?

Shingles, caused by the varicella-zoster virus, can be a painful and debilitating condition. To help prevent shingles, two vaccines are commonly used: Shingrix and Zostavax. In this article, we will delve into the specific advantages and disadvantages of each vaccine, helping you make an informed decision about which one might be better for you.

Shingrix: The Clear Vaccine of Choice

Shingrix is considered the better vaccine for shingles. Studies have shown that Shingrix is 97 percent effective at preventing herpes zoster (shingles) in those over 50. It is more effective, lasts longer, and has fewer side effects compared to Zostavax. In fact, Professor Cunningham from the Journal of Infectious Diseases has highlighted that Shingrix offers protection for up to four years, with some believing it could last even longer.

Shingrix: A Comprehensive Comparison

Shingrix is a recombinant vaccine that uses an inactive form of the virus, thus making it suitable for a broader age range. It is administered in two doses, 2 to 6 months apart. The vaccine triggers a strong immune response, providing long-lasting protection. Shingrix has been associated with a lower incidence of postherpetic neuralgia (PHN) compared to Zostavax.

In contrast, Zostavax is a live attenuated vaccine similar to the one used for chickenpox. It has shown efficacy in preventing shingles in those aged 50 to 70, but its effectiveness wanes over time. Studies comparing the two vaccines have consistently shown that Shingrix outperforms Zostavax in terms of both efficacy and durability. While Zostavax was used since 2006, it has a lower success rate, with an average effectiveness of 50-64 percent in preventing shingles, especially in those over 70.

Benefits and Considerations

Shingrix:

Efficacy: 97 percent effectiveness in preventing shingles in people over 50. Duration: Protection lasts at least 4 years, with some evidence suggesting even longer-lasting immunity. Side Effects: Generally well-tolerated with minimal side effects. Common side effects include pain, redness, and swelling at the injection site, and mild to moderate fever.

Zostavax:

Efficacy: Less effective, particularly in those over 70, with an average effectiveness of 50-64 percent. Duration: Protection is not believed to last as long and may wane over time. Side Effects: More common and severe, including redness, pain, swelling, and itching at the injection site, as well as systemic symptoms like fever, fatigue, and headache.

While Shingrix is more expensive, its higher efficacy and longer-lasting protection make it a preferable choice for many individuals. It's important to note that both vaccines require medical consultation and a prescription.

Conclusion and Further Insights

When it comes to preventing shingles, Shingrix has demonstrated superior performance compared to Zostavax. If you are eligible for vaccination, Shingrix is generally the recommended option.
