There is no justification, but as humans make these things and humans make mistakes...
*Take a look at this:
*"It’s not at all clear that the presence of porcine circovirus 1 DNA in Rotarix is a problem. Circoviruses have not been associated with human disease, and porcine circovirus 1 has not been found to cause disease in any animal. Many humans have antibodies to these viruses, including porcine circovirus, indicating that they were infected at one time. Furthermore, it’s not known if the vaccine contains infectious virus or DNA fragments. Nevertheless, it’s always preferable to err on the side of caution, as the FDA has done."
The virus is unexpectedly small and didn't cause any symptoms in the trials. The PC 1 virus doesn't cause illness in humans or animals and none of the PC viruses have caused illness in humans and are quite common. It's also likely that the virus in the vaccine wasn't even infectious.*
If the contaminant had been illness causing it would've been seen in the testing and the infected batches have been pulled. I'm very sure that further vaccines will be better tested.*
If your sexually active then you are at risk of getting HPV, 70% of cervical cancer is preventable by the vaccine (HPV has been proved to cause cancer, it's causal). Of the 33 million doses given in the US as of feb 2011 there were 32 confirmed deaths (29 unconfirmed, you'd think they'd know!) connected with the HPV vaccines though none of them have been shown to be caused be the vaccine. These deaths, though unfortunate, have been up to six months after having the vaccine and have included car accidents.*
There have been many, investigations in different countries but no pattern or suspicious autopsies that credit the vaccine with the death.*
