The local mandate already requires children and adults over the age of 12 to show proof that they are vaccinated before entering those places. Now, city health officials are planning to extend the health order to children ages 5 to 11, the group newly eligible for the shot.

San Francisco Health Officer Susan Philip said the requirement won't kick in for at least two months.

"We definitely want to wait and make sure children have an opportunity to get vaccinated, so that will happen no sooner than about eight weeks after the vaccine is available for kids," Philip said at a town hall meeting Tuesday about youth vaccinations.
