US coronavirus: There is no question about the effectiveness of vaccines, expert

There is widespread agreement that the vaccines are primarily intended to reduce hospitalizations and deaths — which data shows they do well, CNN Medical Analyst Dr. Leana Wen said.

“What not everybody would agree to is the second thing, which I believe, that the point of vaccination is to also reduce the level of infection,” Wen said.

That is the issue now being debated by officials and health experts, just as the average of new daily cases has shot up over the past two months.

President Joe Biden and many experts say there’s a good reason for a third booster dose. And three reports published Wednesday support the argument that people may need a booster dose of Pfizer’s Covid-19 vaccine over time, and suggest such boosters would be safe.

The reports are part of a batch of data that will be discussed by the FDA’s vaccine advisers as it considers a request by Pfizer to approve a third, booster dose for most people six months after they get their first two doses of vaccine.

But there isn’t unanimity right now. On Monday, a group of international vaccine experts, including some from the FDA and the World Health Organization, wrote in the Lancet that current evidence does not appear to support a need for booster shots in the general public right now.

There also is fear that a focus on boosters will distract from the mission of getting a greater proportion of the public to get their initial doses.

Only around 54% of the US population is fully vaccinated, which experts agree is the best form of protection against the virus.

There is no clear answer yet on whether vaccine boosters are necessary, Dr. Francis Collins, director of the National Institutes of Health, said Wednesday, but there is “a mountain” of data for experts to consider before making a decision.

Friday’s discussion will be public, he added, so people can see the data that goes into the decision.

Local health departments are planning on being ready to roll out booster doses next week if given the green light from the FDA, but many still have questions, Lori Tremmel Freeman, chief executive officer of the National Association of County and City Health Officials, told CNN on Wednesday.

“What is the interval for boosters? Is it any shorter than eight months at this point? What is the age cut-off? Will there be priority groupings?” Freeman said. “We don’t want to be unprepared. We don’t want to appear uncoordinated on boosters.”

Numb to tragedy

As the pandemic continues to take a toll — Covid-19 has killed more than 666,000 people and infected 41.5 million in the US since January 2020 — the public is becoming numb to the tragedy, the former commissioner of the FDA Dr. Scott Gottlieb said Wednesday.

“We are somewhat complacent with a very excessive amount of death and disease,” he said during an appearance at the SALT hedge fund conference in Manhattan.

The US marked another grim milestone Wednesday: 1 in 500 Americans has died of Covid-19.

It’s a number that can be hard to process, Wen said.

“Imagine if 1 in 500 Americans had died in a war due to a foreign adversary in the last year and a half. How would we be processing that information now? What would we be doing differently?” she asked. “Wouldn’t we be doing everything we can to end the war, end the suffering and deaths?

“For us to not do everything we can with vaccines and masks in the meantime, it’s really unconscionable.”

The increasing number of cases among young people is also alarming experts. In the first nine months of 2021, Covid-19 infections among children and adolescents in the Americas (including the US and Canada) reached over 1.9 million, according to Dr. Carissa Etienne, Director of the Pan American Health Organization on Wednesday.

That is more than 400,000 more than there were all of last year — before Covid-19 vaccines were available to young people over the age of 12.

In the US, cases are likely to rise now that schools have reopened in the Northeast, Gottlieb said.

“That’s going to build,” Gottlieb said, pointing to school outbreaks in other regions hit by the Delta variant. “The schools will become sources of spread in the Northeast as well.”

However, Gottlieb, who sits on the board of Pfizer, doesn’t expect the Northeast to get hit nearly as hard as the South, mostly because of prior infections and high vaccination rates.

Most Americans support Covid-19 restrictions

Other strategies officials have promoted to increase virus protection are vaccine mandates and mask requirements.

Last week, Biden announced a plan to tackle the pandemic, which included mandating businesses with more than 100 employees to require their workforce be either vaccinated or regularly tested.

Many states and workplaces had already introduced similar measures.
