The MIT professor who has been appointed by Robert F Kennedy Jr to review the safety of Covid-19 vaccines has failed to meet basic scientific standards in his own research on the topic, according to more than a dozen scientists and public health experts.

Retsef Levi, an operations management professor, is a member of the US health department’s vaccine advisory committee (ACIP) which is meeting later this month and – many experts fear – could seek to rollback recommendations on who should receive Covid-19 vaccines.

Levi, who holds Israeli and American citizenship, has claimed that Covid-19 vaccines are the “most failing medical product in the history of medical products”, despite a body of research that has shown they are safe and effective. A modeling study published in 2022 in the prestigious medical journal The Lancet estimated that Covid-19 vaccines saved nearly 20 million lives in the first year they were available.
