The final result saw 66.40% of the electorate vote Yes and 33.60% vote No.
The bill repealing the Eighth Amendment was signed into law by President Michael D Higgins last month.
Health Minister Simon Harris has asked the Oireachtas Health Committee to sit during the Halloween break to progress the Abortion Bill it as quickly as possible.
