This message is for parents of all incoming 7th grade students coming to the William S. Hart Union High School District for fall, 2021. It is important to know that when your student gets the required Tdap booster vaccine for 7th grade entry, it can not be taken at the same time as the voluntary COVID vaccine. There is a manufacturer waiting period in between vaccines, which may exceed 2 weeks. Please consult your medical provider for more information. Separate appointments may need to be made if both vaccines are administered during the summer months. Please keep in mind that only the Tdap vaccine is a required booster for 7th grade entry as long as all other immunizations are up to date.
