According to officials at the U.S. Centers for Disease Control and Prevention, the Delta variant of the virus is more infectious than preceding variants.

Dr. Rochelle Walensky, director of the CDC, announced the need for everyone to get a vaccine booster eight months after vaccination on Wednesday.

"The available data makes very clear that protection against SARS-CoV-2 infection begins to decrease over time following the initial doses of vaccination, and in association with the dominance of the Delta variant, we are starting to see evidence of reduced protection against mild and moderate disease. Based on our latest assessment, the current protection against severe disease, hospitalization, and death could diminish in the months ahead, especially among those who are at higher risk or were vaccinated during the earlier phases of the vaccination rollout. For that reason, we conclude that a booster shot will be needed to maximize vaccine-induced protection and prolong its durability," Walensky said in a statement.

The booster shots will become available beginning the week of Sept. 20.
