Pregnant women and people over 60 will begin receiving their second booster vaccination against Covid-19 from today.
The Health Service Executive has urged those eligible to get the vaccine.
Since last week, people who are over 60 and women who are pregnant have been able to book their appointments through the HSE.
The injections are being administered at vaccination centres and at participating pharmacies around the country.
People aged between 50 and 64, as well as people with long-term health conditions, will also be offered booster vaccines in the coming weeks.
