Dr Fauci dismisses Mayo Clinic study that claims Moderna COVID vaccine is more effective at preventing Delta variant infection than Pfizer rival
- Fauci urged caution over the data, which he stressed is preliminary
- Suggested fully-vaccinated people who’ve had Moderna shot less likely to catch COVID
- Research was conducted on people who caught COVID in Minnesota during June and July
- Last week, FDA gave emergency approval for booster shots for some fully-vaccinated people who are medically-vulnerable
Asked about the study – done by biotech firm nfrench, which is based at the prestigious Mayo Clinic and Cambridge, Massachusetts, the White House COVID tsar said: ‘That study … is a pre-print study, it hasn’t been fully peer-reviewed.’
Speaking on CBS’s Face the Nation, Fauci added: ‘I don’t doubt what they’re seeing, but there are a lot of confounding variables in there.
‘I don’t doubt what they’re seeing, but there are a lot of confounding variables in there, about when one was started, the relative amount of people in that cohort who were delta vs alpha – right now, if we get boosters … it’s clear we want to make sure we get people, if possible, to get the boost from the original vaccine.’
The study was shared on medrvix last week – a site which publishes preliminary findings, before they have been peer-reviewed and rubber stamped.

It was complied by monitoring samples of people who contracted COVID’s Delta variant – and what shot they had – in Minnesota from January to July.
Fauci was also keep to dispute suggestions that this means Americans wanting to have a third ‘booster shot’ of a COVID vaccine should seek out Moderna’s injection.
Last week, the Food and Drug Administration (FDA) gave emergency approval to a third booster shot of COVID for people who are immunocompromised or have certain underlying conditions.
