Moderna says booster likely needed before winter
By Peter Sullivan - 08/05/21 08:38 AM EDT
Moderna said Thursday that its COVID-19 vaccine maintained 93 percent efficacy six months after the second dose but said that a booster shot will likely still be needed before the winter.
The 93 percent efficacy after six months announced by Moderna ahead of an earnings call on Thursday is a positive sign and compares to 84 percent efficacy after that time for the Pfizer vaccine.
Still, Moderna CEO Stephane Bancel said on CNBC on Thursday that the data was collected before the delta variant became prevalent in the United States, meaning the equation could change now that the delta variant is widespread.
"We are pleased that our COVID-19 vaccine is showing durable efficacy of 93% through six months but recognize that the Delta variant is a significant new threat, so we must remain vigilant," Bancel said in a statement.
