The HSE Crisis Pregnancy Programme is launching its new sexual health promotion campaign later today.
It is aimed at encouraging consistent use of contraception among sexually active young adults.
The new phase of the Think Contraception campaign will use TV sponsorships, on-the-street promotion, poster and digital advertising and social media to promote its key message.
Research by the HSE has shown that 20% of 18-25 year olds did not report consistent use of contraception last year.
