We’re not entirely sure about the idea of a vaccination passport, but it seems like a good idea to have proof that you’re not at risk of spreading COVID-19. If it opens doors, all the better.

Personal medical information is protected under HIPPA (the Health Insurance Portability and Accountability Act of 1996), but letting the world know that you have been vaccinated doesn’t seem like something most of us want to keep private. It’s a matter of pride reflecting your concern for fellow citizens.

In the weekend baseball series between the Los Angeles Dodgers and San Diego Padres at PetCo Park, some fans were required to provide evidence that they had been vaccinated or take a test. Many other public venues have similar requirements.

It’s great news that more than half of Redlands residents have been vaccinated, according to the San Bernardino County Department of Public Health. It’s also great news that everybody 16 and older can now get a vaccination.

Vaccinations are nothing new. Vaccinations for school children for measles, chicken pox, tetanus and other public health threats have been required for generations. Responsible parents make sure that happens.

Pfizer-BioNTech has announced that its vaccine was “100% effective” and safe for children as young as 12. The company plans to ask the U.S. Food and Drug Administration to approve the vaccine for use in adolescents age 12 to 15 before the beginning of next school year.

And, of course, world travelers are required to get a “yellow card” to show that they have been vaccinated against yellow fever and other diseases.

In 1905, the U.S. Supreme Court voted 7-2 to uphold state laws that required vaccinations for communicable diseases, the Los Angeles Times reported on Monday. Justice John Marshall Harlan wrote that “the rights of the individual … may at times, under the pressure of great dangers, be subjected to such restraint, to be enforced by reasonable regulations, as the safety of the general public may be demanded.”

This remains a time of great danger, but it’s getting better. The California Department of Public Health announced that none of the state’s 58 counties remains in the Purple (widespread) Tier. There are 38 counties, including San Bernardino and Riverside, in the Orange (moderate) Tier.

It’s not time to let down our guard. We should still wear masks. If you haven’t been vaccinated, get in line. When you get that card, proudly display it to anyone who is interested.
