If you have a cold after receiving the vaccine, you can take medication, but the medication should be taken under the guidance of a medical professional and should not be taken without authorization.
The vaccines used in the clinic are mainly adenovirus vector vaccine, inactivated vaccine and recombinant subunit vaccine. Taking medication to treat colds after vaccination will not affect the effectiveness of the vaccine, and the medication will not have an adverse reaction with the vaccine components, so medication can be taken to treat a cold after vaccination.
It should be noted that there are two types of colds: common colds and influenza. You should not take medication without authorization, but should go to the hospital and take the appropriate medication under the guidance of a doctor.
