Beware of covid-19 vaccine trials designed to succeed from the start
In response to widespread demand for more transparency, pharmaceutical companiesModernaandPfizerhave released clinical study protocols for their Covid-19 vaccine trials. The goal is to reassure the public that the trials are being conducted responsibly and that any approved vaccine would be safe for all.
But the protocols should heighten anxiety rather than alleviate it. A close reading suggests the clinical trials have been designed to ensure the greatest possible success for these candidates — and that could overstate their effectiveness.
