General questions

How do I know which COVID-19 vaccine to choose or recommend?

All COVID-19 vaccines that have received WHO Emergency Use Listing approval and/or stringent regulatory agencies’ emergency authorization have fulfilled all regulatory approvals and standards. The WHO Strategic Advisory Group of Experts has issued recommendations on the use of several vaccines and will be reviewing more in the coming months. Slight differences on age upper and lower limits, characteristics and properties of the type of vaccine used (for example mRNA, vector, protein based, live attenuated) and individual comorbidities (such as polysorbate allergic reactions or immunocompromised individuals) can lean the scale towards one type or other. Therefore, in very particular cases, a risk-assessment and clinical evaluation may need to be performed to determine the most suitable vaccine for specific vaccinees.
