Characteristics of COVID-19 Vaccines

COVID-19 vaccines are effective in preventing severe illness and symptoms such as fever or coughs. Vaccination is expected to reduce the number of severe COVID-19 patients and deaths.
Some cases of side effects such as localized pain in the injected site, headache, fatigue, muscle and joint pain, and anaphylaxis (acute allergic reaction) after vaccination in some rare cases have been reported.
Through their pharmaceutical approvals, effectiveness and safety of vaccines for COVID-19 has been verified based on clinical trials and scientific findings.
