Osterholm, PhD, MPH, director of the University of Minnesota’s Center for Infectious Disease Research and Policy, writer of CIDRAP News, mentioned he personally and professionally helps the message from the CDC and FDA, however he needs corporations and authorities companies may higher coordinate messages sooner or later.
“The events of the past day only add to the public’s confusion about whether we in the public health community and vaccine communities have our act together, and that’s terribly unfortunate, because it only undercuts our ability to promote these vaccines,” he mentioned.
“This is not a matter of inconvenience; this is a matter of public credibility.”
