All-In U.S. Push for Vaccine Raises Risk Virus Will Linger

The U.S. strategy to rely on vaccines and treatments, rather than emphasizing social distancing, masks and testing nationwide, threatens to delay the return to normal life for Americans.

While the U.S. has committed more than $10 billion to develop new shots to fight Covid-19, about half of Americans say they are wary of taking them, according to a Gallup poll reported this month. Meanwhile, any shortfalls in the vaccine program could mean the country will struggle with the virus well into 2023, according to the London-based firm Airfinity Ltd.

At the same time, cases are climbing as the weather cools and more activity moves indoors. Hospitalizations have risen at least 10% in the past week in 32 U.S. states and the nation’s capital.

Other parts of the world are also in trouble. Some European countries are seeing more new infections each day than in the dismal spring outbreak. But those regions are considering re-instituting containment measures that have become anathema in the U.S. Parts of Asia, meanwhile, seem poised to recover faster.

In the waning days before the U.S. election, the Trump administration’s response is focused on a swift roll-out of vaccines developed in its Operation Warp Speed program. On Sunday, Mark Meadows, Trump’s chief of staff, outlined the strategy on CNN.

“We’re not going to control the pandemic,” Meadows said. “We are going to control the fact that we get vaccines, therapeutics and other mitigations.”

But ending the crisis won’t be quick or easy. Vaccines may initially slow deaths among those with chronic conditions. But the logistical, production and public education challenges of immunizing 60% to 70% of national populations -- the level the World Health Organization says is needed to achieve herd immunity -- will be a time-consuming and troublesome process. The world will still need masks, social distancing, widespread testing and effective new therapies to keep the virus at bay, public-health specialists say.

A vaccine isn’t “a magic wand,” said Marie-Paule Kieny, a research director at the French health-science institute Inserm and a former World Health Organization official. “It will not be a quick fix, even if it’s effective.”
