You can get the new Crown vaccine on the same day you have the nucleic acid done. Nucleic acid refers to nucleic acid testing, which is done in the form of a nasopharyngeal swab, pharyngeal swab, and so on. The new crown vaccine is a medication injected into the outer deltoid muscle of the upper arm that works through the body’s immune system. There is no major correlation between the two, so the vaccine can be given after the nucleic acid as long as you are not experiencing any discomfort. You should stay in the hospital for half an hour after the vaccination to avoid serious adverse reactions. Keep the local skin clean after vaccination and avoid excessive rubbing of the injection site to avoid wound infection. It should be noted that vaccination is generally not recommended if there are symptoms of fever, or if you suffer from upper respiratory tract infection, epilepsy, coagulation disorders and other diseases. Vaccination should be scheduled reasonably according to individual conditions.
