If Gov. Gavin Newsom wants to “fully reopen the economy” in California by June 15, he needs to provide employers, business owners and residents with a vaccine verification method so they can feel safe resuming their normal lives.

California’s economic reopening will still require masks for those who are not vaccinated. The problem is ensuring that they follow the rules. Whether it’s at work, sporting events, movies or grocery stores, Californians deserve the assurance that those around them without masks have been fully vaccinated.
