Factsheets on COVID-19 Vaccines
In partnership with the Asian Development Bank, IVAC developed factsheets summarizing key measures for COVID-19 vaccines such as effectiveness and protection against severe disease.

Key Facts:

- Vaccine protection against symptomatic disease drops quickly
- Protection against severe disease, like hospitalization and ICU admission, is better and durable for many months
- A booster shot substantially improves protection against Omicron infection and disease
- Booster protection against severe disease lasts for many months
