It could take a year — even two — to vaccinate Riverside County if supply issues persist

“Every first shot is a promissory note on the second shot,” Andrew Noymer, an associate professor of public health at the University of California, Irvine, previously told the Desert Sun. “Immunization means getting both of the shots at the proper interval.” … The trials weren’t intended to see what would happen if thousands of people only got one of two required doses or got a second dose at a sporadic interval, so Noymer said public health officials need to follow the limited science that is available. … As he sees it, patients should leave the vaccination site with an already booked appointment for several weeks down the line to get that shot.
