For Massachusetts residents who have struggled to sign up for a COVID-19 vaccine over the past few weeks, the cold open of this week’s “Saturday Night Live” was very on-point. The show opened with a fake game show hosted by Dr. Anthony Fauci (Kate McKinnon) called “So You Think You Can Get the Vaccine,” in which contestants plead their case to three governors — California’s Gavin Newsom (Alex Moffat), New York’s Andrew Cuomo (Pete Davidson) and Michigan’s Gretchen Whitmer (Cecily Strong) — as to why they should be given the vaccine. “Getting the vaccine shouldn’t be a competition, but Americans will only want to get it if someone else can’t,” Fauci’s McKinnon said.
