"The vaccine isn't providing significant benefit at two doses against the risk of transmission, as compared to someone unvaccinated,” Moore said. "We have to reassess the value of the passports in the coming weeks and months."

"When we see a vaccine that doesn’t provide the sterile immunity like it did provide against Delta, we have to reassess some of the public health measures we put in place, reassess whether we maintain a proof-of-vaccination certificate certification process given the decreased benefit against transmission."

Moore said ending the COVID-19 proof-of-vaccination system would ultimately be a government decision.
