A new study raises concerns about the mRNA vaccines’ effectiveness revealing that Pfizer COVID-19 vaccine is only 42% effective against the Delta variant.
A new preprint study (read below) that raises concerns about the mRNA vaccines’ effectiveness against Delta — particularly Pfizer’s — has already grabbed the attention of top US administration officials.
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 study, conducted by nference and the Mayo Clinic, compared the effectiveness of the Pfizer and Moderna vaccines in the Mayo Clinic Health System over time from January to July.
- Overall, it found that the Moderna vaccine was 86% effective against infection over the study period, and Pfizer’s was 76%. Moderna’s vaccine was 92% effective against hospitalization and Pfizer’s was 85%.
- But the vaccines’ effectiveness against infection dropped sharply in July, when the Delta variant’s prevalence in Minnesota had risen to over 70%.
- Moderna was 76% effective against infection, and Pfizer was only 42% effective.
- The study found similar results in other states. For example, in Florida, the risk of infection in July for people fully vaccinated with Moderna was about 60% lower than for people fully vaccinated with Pfizer.
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.
The Pfizer coronavirus vaccine may be linked to a form of severe eye inflammation called uveitis which can lead to permanent loss of vision, according to a multicenter Israeli study led by Prof. Zohar Habot-Wilner from Tel Aviv’s Sourasky Medical Center.
The U.S. Food and Drug Administration earlier added a warning to patient and provider fact sheets for the Pfizer and Moderna Covid-19 vaccines to indicate risk of heart inflammation.
Recently, Health Canada, the department of the Government of Canada responsible for national health policy added Bell’s Palsy as a warning to Pfizer COVID-19 vaccine labels.
Women who have had the Pfizer vaccine are reporting an unexpected side effect – claiming their breasts have grown bigger after having the jab.
The Israeli Peoples Committee (IPC), a civilian body made of leading Israeli health experts, in its April report published the Pfizer vaccine’s side effects indicating damage to almost every system in the human body.
Meanwhile, it has been revealed that Pfizer manipulated COVID vaccine trial protocols in order to obtain emergency FDA authorisation for children.
