“Avoid live virus vaccines and people who have received one
Some vaccines are made from live viruses. Currently, these include oral polio, smallpox, MMR (measles, mumps, and rubella), and nasal flu vaccines.
These vaccines may pose a threat to your child’s health. Any person with a weakened immune system, including patients with cancer or HIV infection should not receive live virus vaccines.
Do not allow people to visit your child if:
They have received oral polio or smallpox vaccines within 4 weeks;
They have received the nasal flu vaccine within one (1) week; or
They have rashes after receiving the chickenpox (varicella) vaccine or MMR (measles, mumps, rubella) vaccine.”
