New York City Mayor Bill de Blasio (D) issued an ultimatum to parents Monday, warning them that their children, ages 5-11, will not be able to particulate in “great things” such as dining in indoor restaurants or going to entertainment venues if they do not show proof of vaccination.

The far-left mayor on Monday announced a series of new vaccine mandates for the city, describing the moves as a “preemptive strike” in the face of the winter months, holiday gatherings, and the omicron variant.

Currently, New York City has a vaccine passport program in place, which requires certain private businesses to discriminate against unvaccinated individuals by denying their entry into the establishments. That discrimination will now extend to children ages 5-11, beginning December 14.
