This week, Dr. Fauci confirmed that “at some time in the future” everyone will likely need a booster shot for the Covid-19 vaccine due to “fading efficacy.”
Now, Axios reports that a new preprint study which has ‘already grabbed the attention of top Biden administration officials’ over the vaccines’ effectiveness against new variants, with Pfizer’s jab being of particular concern.
The study found the Pfizer vaccine was only 42% effective against infection in July, when the Delta variant was dominant. “If that’s not a wakeup call, I don’t know what is,” a senior Biden official told Axios.

The overall figures suggest that the vaccines provide robust (yet lower-than advertised) immunity early on, only to sharply drop in efficacy over time.
Between January and July, Moderna’s vaccine was found to be 86% effective against infection over the study period, while Pfizer’s was 76%. As far as hospitalization, Moderna’s vaccine was 92% effective, while Pfizer’s was 85%.
Bringing the averages down, of course, was the sharp drop in efficacy observed in July with Moderna proving just 72% effective against infection and Pfizer clocking in at 42%.
In other states such as Florida, the risk of infection in July among those who had taken the Moderna vaccine was around 60% lower than for people full vaccinated with Pfizer.

Why it matters: Although it has yet to be peer-reviewed, the study raises serious questions about both vaccines’ long-term effectiveness, particularly Pfizer’s.
- It’s unclear whether the results signify a reduction in effectiveness over time, a reduced effectiveness against Delta, or a combination of both.
- “Based on the data that we have so far, it is a combination of both factors,” said Venky Soundararajan, a lead author of the study. “The Moderna vaccine is likely — very likely — more effective than the Pfizer vaccine in areas where Delta is the dominant strain, and the Pfizer vaccine appears to have a lower durability of effectiveness.”
- He added that his team is working on a follow-up study that will try to differentiate between the durability of the two vaccines and their effectiveness against Delta.
Bring on the boosters.
