The most ambitious mass immunization program in human history began one year ago this month.

For all the social tumult and political noise surrounding the campaign, its successes are notable. Nearly 500 million doses of COVID-19 vaccine have been administered in the U.S., more than 8.7 billion around the world.

In the U.S., 73% of the population has received at least one dose, 61.6% is fully vaccinated (not including boosters), and 30% of those eligible for a booster have had one.

The Commonwealth Fund estimates that the COVID-19 vaccination effort in this country has saved 1.1 million lives and prevented 10.3 million hospitalizations.

And yet the pandemic surges on with newly gathered strength, refueling its toxic tank with another version of the virus. In just three weeks, the Omicron variant has leapfrogged Delta, jumping from 3% to 73% of new U.S. infections.

As we turn our calendars toward another global pandemic year, the immunization campaign has miles to go and millions of arms to reach on the planet. It’s time to take a deep breath, a look back and a look ahead.

In that spirit, we share a timeline snapshot of the year and offer 10 takeaways to carry us into what we can hope will be a better and brighter, safer and healthier 2022.

Parting shot: 10 key takeaways

10. We have to learn to live with this virus. It beats dying from it.

9. 2022 will be a year of reckoning for vaccination mandates. If you have a case of whiplash trying to follow the ups and downs, vax on/vax off, chutes-and-ladders pattern of court rulings, you are not alone. Look to the Supreme Court to provide clarity.

8. Achieving vaccine equity at home and around the world remains high on our to-do list. May we never tire of the WHO message that “none of us are safe until all of us are safe.”

7. When it comes to communicating, we can do much better. MM+M Editor-in-Chief Larry Dobrow laments the “messaging miasma” plaguing this pandemic: soft, shape-shifting and scattershot. The public conversation has become politicized and polarizing. We have to get past this.

6. Core messaging needn’t change. Get vaccinated. Get your booster. Mask up. Socially distance. Wash hands. Be considerate of others. They say we have the basic tools to contain the virus, so let’s use them.

5. Science still rocks. As Sara Holoubek pointed out in MM+M, mRNA technology is “the penicillin of our age.”

4. We must learn to live with uncertainty. Omicron will not be the last variant. Will there ever be an Omega? Will “Succession” ever end?

3. We keep hearing about widespread COVID fatigue. One of the biggest threats to our well-being is the loss of frontline health professionals, who are burned out and walking away “in droves.” That is the not-so-great resignation.

2. Vaccines alone are not the answer. Outmaneuvering the pandemic will require a chess master’s strategy combining prevention (vaccination, public health measures) with widespread testing (vastly underused, we belatedly recognize) and effective treatment (monoclonal antibodies, pills and more)

1. As a new year arrives, let us self-administer a daily dose of hope. Let the pandemic bring out the best in us, the civic spirit that surely lies within. Where there’s a will there’s a way. If we can summon the will, we can find the way.
