Gov. Phil Murphy once again used his COVID-19 briefing to criticize people who are questioning the effectiveness of the COVID-19 vaccine.

Last week, the governor made headlines for shouting at a group of hecklers and calling them “ultimate knuckleheads” for protesting against the vaccine.

On Monday, Murphy had a similar message for the group. He also balked at comments made by Republican nominee for lieutenant governor Diane Allen’s claim that some of the COVID-19 spike around the country is blamed on immigrants coming across the border.

“I think we've kind of had it - Is that fair to say? - in terms of being tougher and more direct. It's like this ridiculous thing about we have COVID because buses came up with illegal immigrants from the border. It's just fantasy land. And folks are saying stuff and believing stuff that's just not true,” Murphy said.

State health officials announced on Monday that there were 884 new positive PCR COVID-19 tests confirmed. The positivity rate for New Jersey stands at 5.18%.

Health officials also said that between July 20 and July 26, 18.5% of all new COVID-19 cases were people who were fully vaccinated against the virus. But the fully vaccinated only accounted for 3% of all new hospitalizations during that same time period. No one who was fully vaccinated died from the virus.

The Centers for Disease Control and Prevention has classified counties in New Jersey as either “substantial” or “high-risk” for coronavirus transmissions.
