(Human-Bovine Reassortant Rotavirus, Live, Attenuated)
Health and Safety Summary Information for Employees Working with:
Human-Bovine Reassortant Rotavirus
SECTION I-IDENTIFICATION
Organism: Human-bovine reassortant strain of rotavirus (WC3 bovine rotavirus backbone containing
one or more human rotavirus RNA segments) (5).
Characteristics: The reassortant rotavirus is not capable of causing disease in adult humans.

SECTION II-HAZARD IDENTIFICATION
Vaccine protects against: Rotavirus infection. Transmission is likely fecal-oral, with possible contact or
respiratory spread. Initial infection is characterized by vomiting and fever, followed by a watery diarrhea
occasionally associated with severe dehydration and death in infants and young children < 2 years old.
Secondary symptomatic cases among adult family contacts can occur, although subclinical infections occur
frequently. Susceptibility is greatest between 6 and 24 months of age. By three years, most individuals
have acquired rotavirus antibodies (4).
SECTION III-HEALTH HAZARDS
Special circumstances:
Immune Status: Changes in the immune system due to cancer or cancer therapy (radiation or
chemotherapy), steroid use, tuberculosis, or diseases of the immune system (including HIV/AIDS)
must be reported immediately to their occupational health group or personal physician, as
appropriate. The US Advisory Committee on Immunizations Practices (ACIP) has recommended
severely immunocompromised individuals not be exposed to live virus vaccines, as there is a risk
of severe complications (1).
Pregnancy: Women who are considering pregnancy should consult with their occupational health
group or personal physician, as appropriate, prior to conception. The wild type virus is not known
to cross the placenta or cause congenital birth defects.
SECTION IV-MEDICAL
Medical Surveillance: There is no routine medical surveillance for persons with a healthy immune system
working with the vaccine strain of rotavirus.
Medical risk for workers: The risk from exposure to the live vaccine virus to a healthy employee appears
to be low to no risk, the same as being given the vaccine. For a pregnant employee, the risk to her and her
unborn child appears to be low to no risk, but the risk cannot be quantified precisely.

SECTION V-RECOMMENDED PRECAUTIONS
Containment/Vaccination Policy regarding this agent: Containment for human-bovine reassortant
rotavirus is BSL1 (BSL1 containment is for organisms not considered to cause disease in healthy adult
humans). Containment for Vero cells is BSL1 (BSL1 containment is for organisms not considered to cause
disease in healthy adult humans).
SECTION VI-HANDLING INFORMATION
Spills: A spill clean-up SOP should be developed. In the event it is not available, the rotavirus is
inactivated by 95% ethanol or phenolics such as Vesphene and LpH. A freshly made 10% bleach solution
will also inactivate the virus, but can damage stainless steel. The standard procedure for any large spill in
an open area is to leave the area for 30 min prior to returning to disinfect the area. Wear gloves, safety
glasses, face mask or respirator (as allowed under national regulation), “bunny” suit, and shoe covers.
