Pittsburgh Public Schools estimates that thousands of students are not up-to-date on their immunizations, so next week it will vote on paying a staff member to reach out to families over the summer, including mass calling, going door-to-door and participating in community events.

The board is scheduled to vote at its legislative meeting at 7:30 p.m. June 24 at board headquarters in Oakland.

The Allegheny County Health Department has added several required immunizations for this fall, and schools must exclude students who do not have proof of having their shots.

In addition to the shots already required, the county has added Tdap (tetanus, diphtheria and pertussis) and meningitis for grades 7 through 12.

For K-12, new requirements call for a second dose of the chicken pox shot unless the child has a history of the disease and a second dose of the mumps shot, which many children already had along with the previously required second dose of a measles shot.

Across the state, many school districts will not have to institute new immunization requirements this fall because they fall under the jurisdiction of the state Department of Health.

The state Health Department had planned to have new regulations in effect that would call for children to be excluded from school if their immunizations were not up-to-date by the end of September. In March, the department issued a letter extending the time in the proposed regulations to the 2010-11 school year. The requirements permit exemptions for medical reasons and religious beliefs.

Another item up for a vote next week includes making Pittsburgh Liberty a full Spanish magnet. Currently, most of the students are part of the magnet, but some are assigned to the school by neighborhood. The neighborhood assignment would not affect students currently enrolled at Liberty.

The board also may hire a firm to do some "green" projects, including installing solar panels at Pittsburgh Brashear High and Pittsburgh South Hills Middle.
