COVID-19 vaccines may be co-administered with other vaccines (including live, attenuated vaccines). This may be at the same visit, or at another visit without regard to timing. 

It is recommended that the COVID-19 vaccine be administered to the left arm and the additional vaccine be administered to the right arm, noting the arm of administration on the vaccination record, where possible.
