“Y'all Need Vaccine” (First posted in February, but looks like I need to post this a second time.) My weekly image & link to a T-shirt. Conceived & designed by fans. Approved by me. After fees to the artist, proceeds go to educational organizations. https://t.co/IMf0ispB6q https://t.co/HIXH702Bvx — PolitiTweet.org
