An ice dam is a ridge of ice that forms at the edge of a roof and prevents melting snow (water) from draining off the roof. The water that backs up behind the dam can leak into a home and cause damage to walls, ceilings, insulation, and other areas.
VARIVAX is a vaccine indicated for active immunization for the prevention of varicella in individuals 12 months of age or older. Each dose is approximately 0.5 mL after reconstitution and is administered by subcutaneous injection.
Children who have never had chickenpox should get two doses of chickenpox vaccine, with the 1st dose administered at 12 â 15 months of age and the 2 nd at 4-6 years of age. Two doses, administered 4-8 weeks apart, are also recommended for people 13 years of age or older. Non-immune persons who have been exposed to chickenpox should receive varicella vaccine to prevent or diminish the severity of illness. The vaccine is most effective if given within 3 days (72 hours) to 5 days (120 hours) of the exposure.
