Herd Immunity Is Humanity’s Great Hope, and It’s Proving Elusive

[andhra_jp]

Variants have become so significant that researchers now say ending the pandemic will be gradual, with bumps along the way. 

The rainforest city of Manaus, Brazil, shows how difficult the virus will be to wrestle into submission without high vaccination rates. 
The city was hit hard early in the pandemic, and one study found that 76% had been infected by October. 
That should have put it in herd immunity territory. 
But in December a deadly new wave struck, driven by the P.1 variant, which suggests there were people who got sick twice. 

There’s no question that widespread vaccination will blunt the pandemic, invigorate the economy, and allow more normal social activities. 
The numbers of deaths and severe cases have plummeted in Israel, which is leading the world’s race to immunize its population. 
But in the bigger and more diverse U.S., vaccines have become a politically polarized issue. 
While more than a quarter of the population is fully immunized, vaccine hesitancy may stymie fuller uptake. 
(Republicans and White evangelical Christians are most likely to say they will abstain, polling shows.) Vaccine supply is already outpacing demand in parts of the country.

Globally the vaccination campaign has barely begun, with enough doses administered to cover just 6% of the world population, according to Bloomberg’s vaccine tracker.
“It boggles my mind to think we can have an immune fortress in America and learn to live with the risk of variants being imported.”

In the long term, the biggest wild card is variants, especially those that reduce vaccine efficacy. 
“I had thought we would see pretty much a normal lifestyle by the second half of 2021,” says David Ho, who heads the Aaron Diamond AIDS Research Center at Columbia University.
Although he still expects steady improvement, the explosion of variants has “decreased my optimism” for a quick conclusion to the pandemic.

Conclusion : 
Eventually the coronavirus could become something more like influenza, steadily mutating in a way that necessitates a never-ending series of booster shots. 
Or 
SARS-CoV-2 could settle down and turn into another common cold.
