The US could soon see Covid-19 cases return to 200,000 a day, a level not seen since among the pandemic’s worst days in January and February, the director of the National Institutes of Health warned on Sunday.
While the US currently is seeing an average of about 129,000 new infections a day – a 700% increase from the beginning of July – that number could jump in the next couple of weeks, Dr Francis Collins said on Fox News Sunday.
“I will be surprised if we don’t cross 200,000 cases a day in the next couple of weeks, and that’s heartbreaking considering we never thought we would be back in that space again,” Collins said.
Collins pleaded anew for unvaccinated Americans to get their shots, calling them “sitting ducks” for a Delta variant that is ravaging the country and showing little sign of letting up.
“That was January, February, that shouldn’t be August. But here we are with the Delta variant, which is so contagious, and this heartbreaking situation where 90 million people are still unvaccinated, who are sitting ducks for this virus, and that’s the mess we’re in.
“This is going very steeply upward with no signs of having peaked out,” he said.
Collins also said the US could decide in the next couple weeks whether to offer coronavirus booster shots to more Americans this fall.
Federal health officials have been actively looking at whether extra shots for the vaccinated may be needed, reviewing case numbers in the US “almost daily” as well as the situation in other countries such as Israel, where preliminary studies suggest the vaccine’s protection against serious illness dropped among those vaccinated in January.
Israel has been offering a coronavirus booster to people over 60 who have already been vaccinated.
No US decision has been made because cases here so far still indicate that people remain highly protected from Covid-19, including the Delta variant, after receiving the two-dose Pfizer or Moderna regimen or the one-shot Johnson & Johnson vaccine.
But US health officials made clear on Sunday they were preparing for the possibility that the time for boosters may come sooner than later.
“There is a concern that the vaccine may start to wane in its effectiveness,” Collins said. “And Delta is a nasty one for us to try to deal with. The combination of those two means we may need boosters, maybe beginning first with healthcare providers, as well as people in nursing homes, and then gradually moving forward” with others, such as older Americans.
He said because the Delta variant only started hitting the US hard in July, the “next couple of weeks” of case data will help the US make a decision.
The Moderna president, Stephen Hoge, said seeing some “breakthrough” infections emerge among the vaccinated within six months had been surprising, even if most symptoms so far have not been life-threatening. “I think that suggests we are going to need booster vaccines to get through the winter,” he told Fox News’s Sunday Morning Futures.
Last week, the Food and Drug Administration(FDA) said people with weakened immune systems can get an extra dose of the Pfizer or Moderna vaccines to better protect them as the Delta variant continues to surge.
“If it turns out as the data come in, we see we do need to give an additional dose to people in nursing homes, actually, or people who are elderly, we will be absolutely prepared to do that very quickly,” said Dr Anthony Fauci, who is Joe Biden’s chief medical adviser.
Both Collins and Fauci stressed that the best way to stem the virus was for the unvaccinated to get their shots.
Currently, about 60% of the US population has had at least one dose and nearly 51% are fully vaccinated, according to the Centers for Disease Control and Prevention (CDC). Areas with low vaccination rates, such as Louisiana, Texas, Florida and Mississippi, have been hit particularly hard with infections.
“That’s heartbreaking considering we never thought we would be back in that space again,” Collins said of surging infections. “But here we are with the Delta variant, which is so contagious, and this heartbreaking situation where 90 million people are still unvaccinated who are sitting ducks for this virus, and that’s the mess we’re in. We’re in a world of hurt.”
Fauci told CBS’s Face the Nation that as more people get their shots, in many places everyone – both the vaccinated and unvaccinated – will have to do their part with “mitigation”, such as mask-wearing in schools and other public spaces.
“We’ve just got to realize that we’re dealing with a public health crisis,” he said. “The more you get infections, the more spread you get, the greater opportunity the virus has to continue to evolve and mutate.”
