The CDC scientist says that even with the delta variant, the ability of corona vaccines to prevent hospitalization has not significantly decreased.
Dr. Sarah Oliver said vaccines are still very effective in preventing hospitalizations.
Vaccine efficacy against hospitalization ranged from 75% to 95%.
On Monday, a scientist at the Centers for Disease Control said that COVID-19 vaccines are still highly effective against hospitalization despite increasing the more transmissible delta variant.
In a presentation to the CDC's Immunization Practices Advisory Committee on Monday, Dr. Sarah Oliver said that since Delta's advent, the vaccine's effectiveness against hospitalization has ranged from 75% to 95%.
The vaccine's ability has ranged from 39% to 84% since the introduction of the Delta variant.
Slides reported that diminished protection over time and a delta variant might contribute to the reduced efficacy of vaccines.
Oliver said it's not uncommon for some vaccines to require multiple doses, including hepatitis and HPV vaccines. However, she said more information is needed before the group can assess the need for the booster injection.
Experts have warned that the spread of the virus, precisely the delta type, could lead to a more severe variant.
"This is a very cunning virus," Fauci said. "If we keep waiting without vaccinating those people who should be vaccinated, this thing could lead to developing another variant, which could be dangerous things."
The presentation added that priority should be given to people most at risk of developing severe diseases in the booster doses.
Oliver also said it's essential to make sure the vaccine is globally available. "The uncontrolled spread globally, which could lead to new variables that threaten the control of the epidemic everywhere," she said in her presentation.
