The companies hope to earn the trust of the public and of scientists who have clamored for details of the studies.
Two drug companies that are leading the race to develop coronavirus vaccines bowed to public pressure on Thursday, abandoning their traditional secrecy and releasing comprehensive road maps of how they are evaluating their vaccines.
The companies, Moderna and Pfizer, revealed details about how participants are being selected and monitored, the conditions under which the trials could be stopped early if there were problems, and the evidence researchers will use to determine whether people who got the vaccines were protected from Covid-19.
Moderna’s study will involve 30,000 participants, and Pfizer’s 44,000.
Companies typically share these documents after their studies are complete. The disclosures while the trials are still underway, a rare move, are aimed at addressing growing suspicion among Americans that President Trump’s drive to produce a vaccine before the election on Nov. 3 could result in a product that was unsafe.
The plan released by Moderna on Thursday morning included a likely timetable that could reach into next year for determining whether its vaccine works. It does not jibe with the president’s optimistic predictions of a vaccine widely available to the public in October.

In this day and age, understanding bacteria and viruses and developing vaccines are national security issues. In my view sizable part of every country’s defense budget should be spent in these pursuits rather than making tanks and other weapons.
