As several coronavirus vaccines inch closer towardFDA approval, the nation's leading infectiousdisease expert has called on the public to doubledown on public health measures. Dr. Anthony Fauci,in a virtual discussion with The Hastings Center onThursday, said the eventual vaccine is meant toprotect the individual from getting sick from thecoronavirus, but may not prevent that person fromspreading the virus to others.


Fauci, when discussing Pfizer and Moderna's results in clinical trials, explained that the vaccinesare being evaluated to see if they prevent clinically apparent disease in the individual, andalso to see if it prevents severe disease in a person who was inoculated. However, it is not yetclear what impact the vaccines may have on transmission.


"We have the same issue with influenza," Fauci said, noting that the two coronavirus vaccinesare far more effective than the seasonal flu vaccine. "You can get vaccinated with influenzaand you won't get sick, but it won't necessarily prevent you from getting infected – althoughyou won't know you're infected because you'll either get mild or no symptoms."


The same concept applies to the eventual COVID-19 vaccine, he said.


"The issue is that you're not going to be completely protected against a degree of infectionthat you might not even notice that you might be able to spread to others," he said. "Which isthe reason why the message you may have heard me say over the last couple weeks in themedia is that getting vaccinated with a highly efficaciousvaccine does not mean that you'regoing to abandon completely public health measures."



Much debate over mask-wearing and whether it's beneficial to the wearer or is helpful instopping the spread has divided the country, particularly as states reenter lockdown modes.Fauci said the public health measures, which include social distancing, avoiding largegatherings, and frequent handwashing should be routine until the level of virus in thecommunity becomes minuscule so that the risk of infection is no longer a threat.


Communication, especially as the issues become politically polarized, has been especiallydifficult, Fauci said, adding that part of the challenge when implementing a public healthpolicy is that it has to be an "all in this together" effort. With recent polls suggesting a decentamount of vaccinehesitancy across the nation, it doesn't indicate that massvaccinationefforts will be a particularly easy effort.


"What we need to do, in a very clear, understandable way, is explain and I try to do this asoften as I possibly can – that the speed [of vaccine development] itself is a reflection ofscientific advances," he said. "In other words, the technology of making a vaccine is not yourgrandfather's technology – it's the 21st century technology."


He added that the federal funding and billions of dollars invested at-risk for development andpre-manufacturing orders have helped speed up the timeline by months if not years.


"Speed has nothing to do with compromising safety or scientific integrity," he said.


As of Thursday, the US had tallied over 11.6 million cases of coronavirus, and more than251,000 deaths.
