Vaccine-Associated Disease Enhancement (VADE): Considerations in Postvaccination COVID-19

Figure 1

The history of vaccinations and development of symptoms in patient 1 after 1 dose of CoronaVac vaccine and in patient 2 after 2 doses of CoronaVac vaccine. In patient 1, two vaccination doses were completed 18 days before the first appearance of symptoms. In patient 2, the patient was vaccinated on the day the symptoms appeared. In both patients, exposure to confirmed COVID-19 cases occurred within 2 weeks prior to the presentation of symptoms.
