(Reuters) - U.S. scientists are skeptical of a one-shot regimen for Pfizer Inc and Moderna Inc COVID-19 vaccines, saying there isn't enough evidence that a single dose provides long-term protection, the Wall Street Journal reported https://www.wsj.com/articles/u-s-scientists-skeptical-of-one-shot-regimen-for-pfizer-moderna-covid-vaccines-11615064919?mod=latest_headlines.
"It is essential that these vaccines be used as authorized by FDA in order to prevent Covid-19 and related hospitalizations and death," Peter Marks, director of the FDA's Center for Biologics Evaluation and Research, told the Journal.
