Vaccines Will Be Less Effective Against Covid Variants: Johns Hopkins

The video discusses the current effectiveness of vaccines in preventing severe illness, hospitalization, and death, despite concerns about reduced efficacy against the Delta variant and other emerging variants. It explores two strategies to combat these variants: administering booster doses to increase antibody levels and modifying vaccines to target new variants, particularly using mRNA and adenovirus vectored vaccines.

What is the significance of booster doses in relation to COVID-19 vaccines?

In what ways can vaccines be altered to address new variants of COVID-19?
