Lyle resident Adrian Bradford can tell you a lot about how one of the Covid vaccines was made. He grew up around the source used for it. Bradford was raised on the shores of Delaware Bay, which connect the state of Delaware on one side and New Jersey on the other. âI grew up in New Jersey, where our family farmlands extended through salt marshes to beachfronts of the Delaware Bay,â Bradford recalls. âOnto those specific beaches, only one month of every year, big prehistoric-looking horseshoe crabs crawled out of the water to perform a function. We watched with interest and amusement, but I didnât know until 2020 they have a blood cell that could protect hundreds of millions of humans.â
