Zostavax is a shingles vaccine made by Merck & Co. It has been on the market since 2006 and is approved for adults over 50. It contains a “live attenuated virus,” meaning it has a living herpes zoster virus that has been weakened — but the vaccine is still 14X stronger than the chickenpox vaccine for children.

Chickenpox and Shingles

Chickenpox and shingles are both caused by herpes zoster. This virus remains inactive in the body for decades after a child recovers from chickenpox. For unknown reasons, it re-activates in older adults and causes shingles.

Can Zostavax Cause Shingles?

Yes. “Shingles” was added to the list of Zostavax side effects in August 2014. The vaccine-strain of virus can also cause other infestations and infections, such as chickenpox, according to the FDA.

What About Blindness?

Yes. The FDA ordered Merck to add “necrotizing retinitis” to the list of Zostavax side effects in February 2016. Eye injuries occur when the virus gets into the eyes and causes inflammation, tissue damage, progressive vision loss, and blindness.

How Effective is Zostavax?

Zostavax only prevents shingles in about 50% of people who get the vaccine. In studies comparing Zostavax to a placebo, shingles occurred in 1.7% of people who got Zostavax vs. 3.3% of people who did not.

What is the problem?

The Clark Firm, LLP is nationally recognized as a class action law firm in Texas, but we are not filing a Zostavax class action. Instead, we are filing individual lawsuits against Merck & Co. on behalf of people who were seriously injured by side effects.

About Class Actions

Class actions are usually filed by one person on behalf of everyone who was injured. This improves efficiency, but it is not designed to maximize compensation for individual members with the most severe injuries.

Why Our Law Firm is Filing Individual Lawsuits as Opposed to a Class Action

Members of class actions may have to accept “low-ball” settlements or higher attorneys’ fees. Most consumer class actions never go to trial. Furthermore, everyone in the class action must share the payout.

Instead of a class action, our lawyers are filing individual Zostavax lawsuits. We help people who were injured by dangerous medications seek compensation for pain and suffering, medical expenses, permanent injuries, lost income, and more.
