In anticipation of any pressure ... American pharmaceutical companies pledge not to announce any vaccine for Corona until it is proven safe and effective.

American pharmaceutical companies have decided not to announce any vaccine against the Coronavirus before they are strictly subjected to safety and efficacy standards.

The New York Times revealed that the goal of the decision, which will be announced next week, is to restore the confidence of the Americans and to confirm that these companies will not announce the production of any vaccine in response to what is said about political pressure by President Donald Trump in this regard.

The newspaper also revealed that groups of drug and drug administration experts are discussing a collective call for the necessity of judging only confirmed scientific data in the production of any vaccine.

This was also confirmed by the Wall Street Journal, which said that a number of companies developing Covid-19 vaccines, including Pfizer, Johnson & Johnson and Moderna, intend to issue a general commitment not to seek government approval for their products before they are proven to be safe and effective.

The newspaper said on Friday that these companies will pledge to adhere to a high level of scientific and ethical standards in conducting clinical studies and manufacturing processes, and cited a joint draft statement that is being finalized.

The Wall Street report, citing two people familiar with the matter, added that the pledge could be issued soon, possibly this week.

This comes amid growing concern that political pressures ahead of the US elections on the third of November will affect the safety and efficacy of any potential vaccine for this respiratory disease.

White House Press Secretary Kelly McKinani said on Thursday that despite the great importance that President Donald Trump attaches to this issue, there is no political pressure on the US health regulator to quickly approve a vaccine.

AstraZeneca, Pfizer and Moderna are among the companies leading the race to develop vaccines to prevent or reduce the severity of Covid-19 disease, as their vaccines are in the final stages of clinical trials.

Pfizer, Moderna and Johnson & Johnson did not immediately respond to Reuters' request for comment.
