How long does dizziness last after the COVID-19 vaccine before resolving spontaneously?
The term “COVID-19 vaccine” generally refers to vaccines developed against the novel coronavirus (SARS-CoV-2). Dizziness following vaccination typically resolves spontaneously within two to three days, although individual responses may vary.
The novel coronavirus vaccine is designed to prevent infection with SARS-CoV-2. If dizziness occurs after vaccination, it is usually related to individual constitution or emotional stress and represents a relatively common adverse reaction. Other associated symptoms may include itching or redness at the injection site, as well as diarrhea or fever. These symptoms are generally mild and resolve spontaneously within two to three days; therefore, excessive concern is unwarranted. However, recovery time may differ among individuals due to variations in physical constitution. During recovery, patients should monitor their blood pressure, rest adequately, and drink plenty of warm water. If dizziness persists beyond three days or progressively worsens, it is unlikely to be attributable to vaccine-related adverse effects. Instead, it may indicate other conditions—such as the common cold, hypotension, cervical spondylosis, or vestibular vertigo—and warrants medical evaluation and treatment at a hospital.
Note: After vaccination, care must be taken to protect the injection site—avoid contact with water or touching it with hands—to prevent local infection.
