In the public imagination, the arrival of a coronavirus vaccine looms large: Its the neat Hollywood ending to the grim and agonizing uncertainty of everyday life in a pandemic.But public health experts are discussing among themselves a new worry: that hopes for a vaccine may be soaring too high. The confident depiction by politicians and companies that a vaccine is imminent and inevitable may give people unrealistic beliefs about how soon the world can return to normal and could lead to resistance to simple strategies that can tamp down transmission and save lives in the short term.
-------
As the plotline advances, so do expectations: If people can just muddle through a few more months, the vaccine will land, the pandemic will end and everyone can throw their masks away. But best-case scenarios have not materialized throughout the pandemic, and experts who believe wholeheartedly in the power of vaccines foresee a long path ahead.
It seems, to me, unlikely that a vaccine is an off-switch or a reset button where we will go back to pre-pandemic times, said Yonatan Grad, an assistant professor of infectious diseases and immunology at the Harvard University T.H. Chan School of Public Health.
--------------
The declaration that a vaccine has been shown safe and effective will be a beginning, not the end. Deploying the vaccine to people in the United States and around the world will test and strain distribution networks, the supply chain, public trust and global cooperation. It will take months or, more likely, years to reach enough people to make the world safe.
For those who do get a vaccine as soon as shots become available, protection wont be immediate it takes weeks for the immune system to call up full platoons of disease-fighting antibodies. And many vaccine technologies will require a second shot weeks after the first to raise immune defenses.
Immunity could be short-lived or partial, requiring repeated boosters that strain the vaccine supply or require people to keep social distancing and wearing masks even after theyve received their shots. And if a vaccine works less well for some groups of people, if swaths of the population are reluctant to get a vaccine or if there isnt enough to go around, some people will still get sick even after scientists declare victory on a vaccine which could help foster a false impression that it does not work.

But, an effective vaccine or treatments would change the calculus.
