At least three of the companies working to develop a coronavirus vaccine are putting together an unusual joint pledge promising not to seek approval for their vaccines until they have been proven safe and effective, the Wall Street Journal reported Friday. 

The Wall Street Journal said the pledge would be aimed at calming worries about a rush to approve a vaccine early, before trials have adequately demonstrated whether any experimental immunizations really work. 

“We believe this pledge will help ensure public confidence in the Covid-19 vaccines that may ultimately be approved and adherence to the rigorous scientific and regulatory process by which they are evaluated,” the newspaper quotes a draft statement as saying. 

The newspaper said it reviewed a draft of the statement that was being finalized by companies that include Pfizer, Moderna and Johnson & Johnson. Pfizer and Moderna have vaccines in late-stage, Phase 3 clinical trials in the US; Johnson & Johnson is preparing to start one.

It quoted “two people familiar with the matter” as saying the pledge may be released next week.

Moderna said in an email to CNN that it had “no comment on any potential outreach, but reaffirms our own commitment to ensuring that safety and efficacy data from our Phase 1, 2 and 3 trials drive any regulatory decisions regarding use of our COVID-19 vaccine candidate.”

Pfizer and Johnson & Johnson did not immediately return CNN’s requests for comment. A spokesperson for GlaxoSmithKline, which also has a coronavirus vaccine in clinical trials in the US, was unable to confirm reports about a pledge.
