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 primary benefit of current vaccines according to the discussion?

• Eliminating the virus completely

• Protecting against severe illness and death

• Reducing the spread of the virus

• Preventing mild symptoms

What is a major concern regarding the Delta variant?

• It is completely resistant to vaccines

• It is less contagious than other variants

• It only affects older adults

• It may cause more severe disease

What is a key question raised about vaccines and new variants?

• How effective are vaccines against new variants like Lambda and Omega?

• How quickly can vaccines be distributed?

• How much do vaccines cost?

• How many doses are required for full protection?

What is one strategy to improve vaccine effectiveness against variants?

• Using herbal remedies

• Administering booster doses

• Avoiding vaccination

• Reducing the dosage

How can mRNA vaccines be adapted to target new variants?

• By changing the color of the vaccine

• By altering the gene for the spike protein

• By reducing the number of doses

• By increasing the storage temperature
