  • Tdap

    All students entering 7th grade are required by law to have proof of a whooping cough booster (Tdap) shot in order to attend classes.  Proof of immunization may be turned in to the main office or turn in a copy to the CRC from 7:30 am until 4:30 pm.   Immunizations should be obtained from your Healthcare provider. If your child does not have health insurance or has Medi-Cal, they can receive immunizations from the RUSD Health Center (5700 Arlington Ave, Riverside 92504). Walk-in Health Center hours: Monday thru Friday from 1:30 PM- 4:00 PM. Beginning August 29th, the first day of school for 2016-2017, 7th grade students who do not have documentation of this immunization will not be able to attend school until documentation is presented to the school. Thank you!
