Christine Maggiore chose not to take antiretroviral drugs or other measures which reduce the risk of mother-to-child transmission of HIV during her pregnancies. Maggiore also breastfed her children, despite evidence that breastfeeding can also transmit HIV from mother to child. Her youngest daughter, Eliza Jane, was never tested for HIV, nor did she or her older brother Charlie receive any of the recommended childhood vaccines. Maggiore later reported Charlie to have tested HIV-negative three times, and asserted that both were in good health.
