During ONE Valentine’s week, ONE’s UK youth activists headed to Parliament to declare their love for life-saving vaccines. At ONE, we brought together voices from across the UK, including volunteers, charities and MPs for a jam-packed day of action to talk about Gavi, the Vaccine Alliance. Great to see @ella_r03 again campaigning on vaccinations. One of the best uses of the #UKAid budget. Saves huge numbers of lives and helps global health security. @gavi @DFID_UK @ONECampaign pic.twitter.com/KOr6jXgpqe — Penny Mordaunt (@PennyMordaunt)...
