The city Guildhall was transformed into a walk-in vaccine clinic.
Residents over the age of 18 were able to drop by and get their dose throughout Saturday and Sunday.
It was open between 9.30am and 7.30pm with vaccines available on a first-come, first served basis.
And it had some special guests the day before with members of Southampton FC turning up for their jab.
Fantastic to be joined yesterday by @SouthamptonFC players as we prepare our walk-in COVID-19 vaccination centre in Southampton Guildhall ��⚽��
If you're aged 18+ & haven't had your first jab, it's open on Saturday and Sunday from 9.30am #grabajabsoton#covidvaccine#grabajabpic.twitter.com/Of4EcXytpd— Hampshire and Isle of Wight Integrated Care System (@HIOW_ICS) July 9, 2021
