USA TODAY panel says US has nailed the science behind COVID-19 vaccines, but logistics, trust remain a concern – USA TODAY
Experts are thrilled about the reported safety and effectiveness of two COVID-19 vaccines rolling out across the country.But they remain concerned about what still could go wrong to shake the public's fragile faith in it.
Nearly everything about the process has gone well so far, shepherded by the Trump administration's Operation Warp Speed.
Thefirst two vaccines, one from Pfizer-BioNTech and the other from Moderna,were ready well before anyone expected. Trials showed them tobe among the most effective vaccines ever, particularly for a notoriously hard-to-prevent respiratory virus.
And the initial days of the rollout, while far from perfect, have already led to 1million vaccinations in the U.S., mostly among front-line health care workers.
Federal officials expect 20 million doses to be manufactured and available for shipping by early January, an additional30 million doses by the end of that month, and 50 million more by the end of February.
Vaccinesshould becomeavailable for the general public as soon as late February or early March, according to Health and Human Services Secretary Alex Azar.
In interviews with USA TODAYover the past several days, a dozen vaccine experts were more guarded. Most believe vaccines won't become widely available until late spring or early summer, assuming no production problemsand the authorization of two additional vaccines by sometime in February.
The federal government should underpromise and overdeliver, advised panel member Dr.Kelly Moore,associate director of immunization education at theImmunization Action Coalition, a nonprofit thatdistributes information about vaccines and the diseases they prevent.
"Projecting concrete dates that we cannot know risks setting the public up for needless frustration and disappointment," she said.
The panel members'concernsmainly revolvearound what will happen before vaccines are widely available.
They worrythe public could lose faith in the vaccinebecause of more allergic reactions like those already seen a few times or some other symptom whether it's actually linked to the vaccine or not.
And they're concerned about potentialglitches in distribution or any of the thousands of other things that could go awry with such a complex scientific, logistical and political process.
"Areas of particular concern," Moore said, "include unpredictable supply issues, storage and handling failures resulting in vaccine waste, and all sorts of data management and data sharing challenges resulting from the use of several new IT systems."
Every month, members ofUSA TODAY'sexpert panelgauge theprogress of COVID-19 vaccines by choosingthe time on an imaginary clock that beganat midnight with the discovery of the virus in early 2020and ends at noon,when a vaccine is freely available across the U.S. Each month, we calculate the median time the midpoint of their estimates.
In June, that was 4 a.m. By October, the sun had risen and their consensus fell at8 a.m. The time for Novembershot ahead to 9:30 a.m. the biggest advance in a month to that point. For December, the panel returned to its steady pace and advanced the clock one hour to 10:30 a.m.
Overall, panelists said they'reimpressed with the development and manufacturing of the first two authorizedvaccines.
"Manufacturing has been managed remarkably well," saidPrashant Yadav, a medical supply chain expert andsenior fellow with theCenter for Global Development, an international development think tankbased in Washington, D.C., and London.
Typicallywith a fast scale-up, "we usually have more hiccups," Yadav said.
Concerns have turned out to be overblown aboutmaintaining the Pfizer-BioNTech vaccine at the necessarysupercold temperature, saidPrakash Nagarkatti, vice president for research at the University of South CarolinainColumbia.
Several panel members said they were pleasantly surprised bothvaccines appearsafe with no major, long-term problems and aremore than 94% effective.
"I was worried that the vaccine(s) would not be this effective but was thrilled with the results," said Dr.Monica Gandhi,an infectious disease researcherat the University of California, San Francisco.
"This is amazing and very impressive," said Pamela Bjorkman, astructural biologist at the California Institute of Technology. "I was worried about serious side effects from vaccinations, but there appears to be little to no evidence ofthis so far."

Many of the panelists said they're still worriedsomething will go wrong, causing the public tolose trust in the vaccine.
Right now, the biggest concernsare allergic reactions, which are rare but seem to be occurring more frequently than they should be,and a handful of cases of Bell's palsy, a neurological condition affecting muscles on one side of the face.
It's usually temporary, but Dr. Paul Offit,director of the Vaccine Education Center and an attending physician in the Division of Infectious Diseases at Children's Hospital of Philadelphia, fretsthat more cases may drive people away from getting vaccinated.
"I'd like to see that not be a big problem," he said.
Sometimes, relatively rare events like Bell's palsy crop up more often than they should purely by chance. If you flipped a coin as many times as there were people in both vaccine trials, you could end up with heads five times in a row, henoted. "That's the tyranny of small numbers in large databases."

Offit, who is eager to get the vaccine himself in the next week or two, said he was concerned recently when he met a phlebotomist who won't take the vaccine because he's convinced that Black Americanssuch as him will get a different vaccine from white Americans though of course that's not true.
"What worries all of us is that there would be a serious adverse event that was permanent," Offitsaid. "Then people would recalculate whether they think it's worth gettingthe vaccine."
Even if a side effectis extraordinarily rare and the likelihood of being infected withCOVID-19remains quite high, people may turn away from the vaccine, he said.
"Statistically, they'reprobably still so much better off getting the vaccine, because this is a common virus, a virus which even if it doesn't kill you can cause permanent harm," he said. "But people don't view risk that way," andpeople may conclude against scientific evidence that the danger posed by the vaccine outweighs that of the virus.
Among the panelists' other worries: There's plenty of time for serious production problems. Rich people could try to jump the line. Andone scenario is out of anyone's control: The virus could mutate to make the vaccines less effective.
The risk of mutation "increases the longer we let millions of people continue to get infected and transmit the virus from one to another," saidDr.Gregory Poland,director of theMayo Clinic's Vaccine Research Group andeditor-in-chief of the journalVaccine.

Still more panelists expressed concern about the lack of federal outreachto reassure people that the vaccine is safe.
Peter Pitts, president and cofounder of the Center for Medicine in the Public Interest, said it'simportant that Vice President Mike Pence was publicly vaccinated this week. That"sends an important message to his core constituency many of whom are vaccine skeptics that now is not the time to allow lingering political animus to trump public health priorities."
More still needs to be done, he said, to reach out to communities of color who are hesitant to take the vaccine.
"Having an abundance of safe and effective vaccines is a tremendous victory," saidPitts, a former Food and Drug Administration associate commissioner for external relations."Failing to coordinate access and convince our fellow citizens to roll up their sleeves and do the right thing would be an inexcusable failure."
People will need to be remindedto get their booster shots both vaccines authorized so far require two doses andto continue taking precautions like wearing masks and maintaining distance until transmission has been stopped, saidSandra Crouse Quinn,senior associate director of the Maryland Center for Health Equityand chair of the department of family science at the University of Maryland School of Public Health.
"All of that said, and of course, I could say more," she said,"these are fabulous developments the first glimmer of a light at the end of the tunnel."
USA TODAY asked scientists, researchers and other expertshow far they think the vaccine development effort has progressed since Jan. 1, when the virus was firstrecognized. A dozen responded.Weaggregated their responses and calculated themedian, the midway point among them.
