Prevention and management of adverse events following COVID-19 vaccination using traditional Korean medicine: An online survey of public health doctors

BACKGROUND Since February 2021, vaccination against coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 has started in Korea. AIM To perform a questionnaire survey about the prevention and management of adverse events of COVID-19 vaccination among public health doctors of Korean Medicine (PHKMDs). METHODS An online questionnaire was developed, comprising categories about adverse events of vaccination (AEVs) and perception of using Korean medicine (KM) in managing vaccine adverse events (AEs) among PHKMDs. PHKMDs' experience of AEVs, usage of Korean medicine for AEVs, and perception and attitude in using KM for AEVs were surveyed. The survey web-link was emailed to the association of PHKMDs. Online links were sent through Survey Monkey to all PHKMDs in Korea. RESULTS A total of 143 participants were recruited for this study; 65% of participants were vaccinated at the same of the survey (n = 93). Although most participants did not take any medication for prevention of the adverse events, 62% (n = 58) of participants had taken herbal medicine to treat the adverse events (n = 52). Approximately 35% of participants (n = 33) said that they would recommend taking herbal medicine to prevent any AEVs. From various KM interventions, the participants strongly recommended taking an herbal medicine (n = 69, 74.19%) to treat AEs, and the second-highest was acupuncture treatment (n = 19, 20.43%). CONCLUSION Overall, this research demonstrated a high prevalence of KM usage by the PHKMDs. Hence, this study's results may serve as fundamental evidence for health professionals to consider using KM treatments when treating or preventing AEVs in the near future.
