Drug maker Merck & Co. faces a growing stack of lawsuits in Philadelphia over its blockbuster shingles vaccine Zostavax, which plaintiffs allege can cause serious side effects ranging from blindness to paralysis to brain damage and even death. Merck, meanwhile, “stands behind the demonstrated safety and efficacy” of Zostavax.

Plaintiffs allege Zostavax can cause blindness, paralysis, and even death.

The U.S. Food and Drug Administration (FDA) approved Zostavax to reduce the risk of shingles in 2006. Over the past ten years, Merck says it has been administered more than 36 million times.

But attorneys say there will be hundreds if not thousands of complaints from patients who are suffering extreme side effects not listed on Zostavax’s warning label. These plaintiffs should feel encouraged by Merck’s history of settling these cases for millions, sometimes billions of dollars.

If you or a loved one received the Zostavax vaccine and experienced severe complications—such as blindness, paralysis, brain damage, liver failure, or death—please contact us today to see if you are eligible for compensation.

Zostavax Sales Totaled Roughly $700 Million in 2016

Zostavax is a more potent version of Merck’s chickenpox vaccine, Varivax. It is purported to reduce the risk of contracting shingles by about 50%.

Merck says that the vaccination has been administered more than 36 million times in more than 50 countries.

The FDA approved Zostavax in 2006; in the decade since, the vaccine has become one of Merck’s bestsellers, with sales totaling between $685 and 749 million in 2016. (These numbers vary by source.) That’s because it is the only shingles vaccine on the market, and was recommended by the Centers for Disease Control and Prevention (CDC) for people 60 and older.

(Note: Zostavax’s patent protection recently expired in the U.S., so the market will soon become much more competitive, especially with GSK’s Shingrix joining the field in the near future.)

That recommendation may fall by the wayside in the wake of this recent spate of allegations, and the hundreds or thousands of patients who may have suffered health problems as a result of Zostavax.

Merck says that the vaccination has been administered more than 36 million times in more than 50 countries—which the company considers a testament to its safety. In response to the lawsuits, Merck issued a statement:

“Nothing is more important to Merck than the safety of our medicines and vaccines. Merck stands behind the demonstrated safety and efficacy of Zostavax, which has been licensed in over 50 countries.”

But given Merck’s checkered history in these matters, one has reason to doubt this statement.

Merck Paid $5 Billion to Settle Vioxx Cases

Merck & Co. is an American pharmaceutical giant founded by George Merck in 1917. Its 2015 revenue was $39.5 billion, making it one of the most profitable pharmaceutical companies in the world.

Its most notable products include the arthritis medication Vioxx, the river blindness medication Mectizan, the osteoporosis medication Fosamax, and of course Propecia.

Like many Big Pharma corporations, Merck has a history of questionable ethics and business practices, especially pertaining to Vioxx:

  • From 2002 to 2005, Merck’s Australian affiliate paid a Dutch publisher called Elsevier to put out a “medical journal” called the Australasian Journal of Bone and Joint Medicine. The journal presented itself as independent and peer-reviewed, and featured many articles that favored Merck medications.
  • In 2007, Merck paid nearly $5 billion to settle several lawsuits related to Vioxx, which Merck pulled from the market in 2004 after the drug was shown to increase the risk of heart attacks and strokes.
  • In 2008, Merck paid $650 million to settle U.S. Justice Department charges that it overcharged the Medicaid program for its drugs. This was one of the largest settlements of its kind in American history.
  • In 2011, Merck paid $950 million settle yet another Justice Department charge, this one over its unlawful marketing of Vioxx.
  • In 2016, Merck agreed to pay $830 million to settle a class action securities lawsuit regarding Vioxx.

Given this checkered history, it is not especially surprising that Merck now faces lawsuits over Zostavax—and may have to shell out hundreds of millions to settle these cases.

Shingles Can Have Serious Complications

Complications that can arise from shingles include blindness, hearing problems, pneumonia, brain inflammation, and death.

Shingles (herpes zoster), the virus Zostavax is meant to guard against, is a rash that resembles chickenpox and usually occurs in a stripe on one side of the face or body. People with weak immune systems and those over the age of 50 are most susceptible to shingles.

In addition to itching, irritation, pain, and scabs/blisters, the side effects of shingles can include:

  • Fever
  • Chills
  • Headache
  • Stomach pain

Shingles rashes typically scab over in 7-10 days and then clear up after 2-4 weeks. But serious complications can arise from the virus, including post-herpetic neuralgia (PHN), a pain that lingers for weeks or even months after the rash has cleared up. In rare cases, people can suffer pain from PHN for years. As with shingles, the elderly and infirm are more likely to develop PHN.

Other complications that can arise from shingles include eye disease and blindness, hearing problems, pneumonia, brain inflammation, and death.

Because shingles’ side effects can be so serious, millions of people have taken the precaution of getting vaccinated against the virus. But it seems like that precaution can backfire in a devastating way.

Alleged Zostavax Side Effects

Some of the side effects alleged in the Zostavax lawsuits are extremely serious, even fatal. They include:

  • Blindness/blurred vision
  • Paralysis in the extremities
  • Brain damage
  • Liver failure
  • Death

None of the effects above are found on Merck’s list of possible Zostavax side effects. If attorneys can prove that the injuries experienced by plaintiffs are linked to the Zostavax vaccine, Merck should be held liable for failing to warn patients of these devastating side effects. 

Zostavax Lawsuit Allegations

Jorja Bentley’s complaint (filed in Philadelphia) includes claims for the following:

  • Negligence
  • Design defect
  • Failure to warn
  • Breaches of express and implied warranties
  • Fraudulent and negligent misrepresentation
  • Unjust enrichment

The complaint seeks compensation for medical bills, lost wages, pain and suffering, and punitive damages. For more information on these complaints and whether or not you might be eligible for a lawsuit, please see our Zostavax lawsuit page.
