- This means the vaccine prevents people from spreading COVID-19 even when they’re asymptomatic, which has been one of the dangerous ways the coronavirus has spread throughout the world.
- The data reportedly showed the Pfizer vaccine is 94% effective in stopping the asymptomatic spread and infection, according to ABC News.
The researchers said the Pfizer vaccine is 97% effective in stopping the symptomatic spread, which is close to the 95% number Pfizer originally announced, as I wrote about for the Deseret News.
Why this matters
- “This is extremely important … for society,” Bourla told CNBC. “The asymptomatic carriers and patients are the ones spreading the disease mainly. We were expecting something good in terms of symptomatic,” he said.
- Bourla said he did not expect to see such a “high number” against asymptomatic cases.
One more thing …
The researchers said 80% of the cases were from the U.K. variant B.1.1.7, which is a sign that the Pfizer vaccine can be effective against that variant, ABC News reports.
