The Robstown Independent School District is urging parents to ensure their children meet new immunization requirements for the coming school year.

Students entering kindergarten and the seventh grade in particular will be affected by the new rules, RISD Director of Nurses Phyllis Castro said.

"Our students are being urged to see their family doctor or visit one of our local clinics to receive these vaccines during the month of June or early part of July to receive their updates and avoid delaying entry to our schools," Castro said. "All students seeking enrollment to the RISD must meet the new requirements."

Changes to school immunization requirements for five vaccines take effect Aug. 1 according to Texas Department of State Health Services officials.

"The changes were made to update the Texas elementary and secondary school immunization requirements to more closely match recommendations by the U.S. Centers for Disease Control and Prevention and the Advisory Committee on Immunization Practices," Jack Sims, DSHS immunization branch manager, said in a press release.

Changes affect mainly students entering kindergarten and seventh grade.

All immunizations must be completed by the first day of attendance at public and private schools.

The vaccines and new requirements are as follows:

Hepatitis A vaccine

Students entering kindergarten statewide must have had two doses of the hepatitis A vaccine.

Measles, mumps, rubella vaccine

Students entering kindergarten must have had two doses of the MMR vaccine. Students in grades 1 through 12 must continue to meet the current requirement, which is two doses of a measles-containing vaccine and one dose each of mumps and rubella vaccine.

Varicella vaccine

Students entering kindergarten and seventh grade must have had two doses. Students in grades 1 though 6 and 8 through 12 must continue to meet the current requirement, which is one dose of varicella vaccine.

Tetanus, diphtheria, acellular pertussis-containing vaccine

Students entering seventh grade must have had one dose of TDAP vaccine.

Students in seventh grade must have had a booster dose of Tdap, but only if it has been five years since their last dose of a tetanus-containing vaccine.

Students in grades 8 through 12 must have had a booster dose of Tdap if it has been 10 years since their last dose of a tetanus-containing vaccine.

Meningococcal vaccine

Students entering seventh grade must have had one dose.

"A student may be enrolled provisionally if the student has received at least one dose of each required vaccine," Sims said. "To remain enrolled, the student must complete the required doses in each vaccine series on schedule and as quickly as is medically feasible."

Parents who may need more information may contact one of two school nurses who will be on duty at the district during summer school. Those nurses will be locates at Seale Junior High School and Salazar Elementary School, Monday through Thursday, from 8 a.m. to 1 p.m. Summer school ends June 25.
