Between 10 days and three weeks after their birth, the calves would begin bleeding uncontrollably from their eyes, ears, and even their skin. Farmers called the illness “bleeding calf syndrome” or even “blood sweating.”
The disease spread from Germany to other European countries, killing up to 15 percent of calves at some farms. Thousands died. Scientists found that the bone marrow and blood cells of the calves had been destroyed.

The connection between the vaccine and the bleeding disorder was evident as early as March 2009, German public health regulators reported in 2011. But Pfizer continued to sell the vaccine in Germany for another year, stopping only weeks before the German government officially opened an investigation into the medicine in late April 2010.

A month later, Pfizer stopped selling PregSure BVD worldwide. Even so, the company continued to insist it did not think its vaccine was unsafe.
“The evidence currently available at European level indicates that BNP is likely to have a multifactorial cause," Pfizer told an Irish newspaper in September 2010, when European regulators officially recalled the vaccine. "The association of BNP with the use of PregSure BVD is not clear.”
Eventually it would be. In the meantime, regulators and Pfizer didn’t continue to expose vulnerable calves to the vaccine.
