Speaking on Good Morning Ulster, Givan said that his bill is "an opportunity for people to come together and fight a prejudicial, discriminatory piece of legislation," referring to the existing abortion law.
Laws such as the Disability Act of 1995 have provided "support" for "people with disabilities," he said - support which should be extended to the unborn.
"I believe that those rights - and these are human rights - ought to be conferred upon people before they are born and that is what this campaign is going to be about," he said.
Abortion became legal in Northern Ireland in April, 2020, after the British parliament imposed changes to the region's abortion and marriage laws and the local devolved legislature failed to block the changes.
Before March 31, abortion was legally permitted in Northern Ireland only if the mother's life was at risk or if there was risk of long term or permanent, serious damage to her mental or physical health. The region was not included in the United Kingdom's Abortion Act of 1967, which legalized abortion.
