Some people are seeking out a second dose of Covid-19 vaccine after getting J&J shot

Jason Gallagher, an infectious disease pharmacist in Philadelphia had gotten the Johnson & Johnson Covid-19 vaccine through a clinical trial in November, but this summer he didn't like the direction Covid-19 cases were taking due to variants. 'Come June, I started to get nervous about this Delta variant spreading and had some travel plans,' said Gallagher, a clinical professor at Temple University School of Pharmacy. So, Gallagher decided to get a dose of a different mRNA vaccine, even though he was already considered fully protected with his single dose of the J&J vaccine.
