But many say they don’t plan to get vaccinated — which has bigger consequences than they might think.
“We really need to get people 20 to 49 years old vaccinated because they are the ones driving the pandemic right now,” said Dr. Carlos del Rio, executive associate dean at Emory University School of Medicine.
Here are the top 10 reasons why young, healthy adults need to get vaccinated as soon as possible:
‘Covid-19 doesn’t have to kill you to wreck your life’
“Even for young people who consider their risk of severe Covid to be low, the long-term consequences can be quite serious,” said Dr. Francis Collins, director of the National Institutes of Health.
“Long Covid represents one more reason to encourage everyone age 16 and over to get vaccinated as quickly as possible.”
“I cannot tell you how many people I’ve taken care of in the ER — who are in their 20s, 30s and 40s — who are never sick enough to end up in the ER with Covid but who now have long-lasting respiratory difficulties,” Ranney said.
“Or they have persistent loss of taste and smell, and they’re losing weight because there’s no joy from eating. Or they have that kind of brain fog that we hear about with long Covid,” she said.
“I think there’s this false sense of both ‘I’m immune to it just because I’m young,’ and ‘Even if I catch it, I’ll be fine.’ You may be lucky. And that may be true — that if you catch it, you’ll be fine. But there’s also a chance that you won’t.”
Some long-haul symptoms in young people have lasted a year now — “debilitating symptoms that have come in the aftermath of their coronavirus infection,” said Dr. Jonathan Reiner, professor of medicine and surgery at George Washington University.
“So what I would say to young people is that Covid-19 doesn’t have to kill you to wreck your life.”
Strong, healthy immune systems can backfire
When young, healthy people do succumb to Covid-19, cytokine storms are often a factor, said Dr. Paul Offit, director of the Vaccine Education Center at Children’s Hospital of Philadelphia.
“But the reason the young died was because they had a vigorous immune response — the so-called cytokine storm, where your body makes immunological proteins that actually cause harm.”
If young people don’t get vaccinated, it could leave everyone vulnerable
The longer coronavirus spreads, the more it mutates. And if the mutations are significant, they could lead to new strains that can’t be fought off with current vaccines.
“They don’t completely escape, but they’ve started to escape,” he said. “They’re warning shots.”
While vaccines still work against those strains and the highly contagious B.1.1.7 strain, “there may be future variants for which we are not so lucky,” Ranney said.
So the key to ending this pandemic isn’t just to get vaccinated. It’s to get vaccinated as soon as possible, before the virus mutates into new strains that can’t be controlled with current vaccines.
Getting vaccinated will help the economy
Many restaurants, bars, movie theaters and sporting venues aren’t open at full capacity — either because Covid-19 case numbers are still too high or because not enough people have been vaccinated.
By getting vaccinated, young people can help more businesses fully reopen safely by increasing safety and driving down infections. That would also help young employees who have been hit hard economically.
“It’s important to vaccinate as many adults as possible as soon as possible,” Los Angeles internal medicine specialist Dr. Jorge Rodriguez told CNN.
“If you want to open up America, get vaccinated.”
Vaccines can save people lots of money
Covid-19 could get very expensive. Medical bills. Lost work days. And the potential for more doctors’ visits if you get long Covid.
The cost of a Covid-19 vaccine? “It’s all free,” Offit said. “The government is paying for this.”
“If you get the virus, and you’re out of work for weeks or months, how do you pay your bills?” Reiner said.
Getting vaccinated can up your dating game
For those on the dating scene, “getting vaccinated or being open to getting it is the hottest thing you could do,” said Michael Kaye, spokesperson for the dating site OKCupid.
Vaccines are also playing a bigger role on Tinder.
In just three months, the dating app had a 258% increase in profile mentions of the word “vaccine,” spokesperson Dana Balch said.
Young people (or their friends) may be at higher risk than they think
And more than 40% of all US adults have at least one underlying condition that can put them at higher risk of severe complications, according to the US Centers for Disease Control and Prevention.
As a person’s body mass index (or BMI) increases, so does their risk for severe Covid-19 — and this risk “is particularly notable” in adults younger than 40, according to the study based in the UK.
“People with excess weight, even without other comorbidities, are at substantially increased risk of admission to hospital and ICU and death due to COVID-19, especially for younger adults and Black people,” the researchers wrote.
A new strain is spreading rampantly
“The B.1.1.7 variant has mutations that allow it to bind more” to cells, Reiner said.
In other words: “You can be in a place and maybe have a briefer exposure or have a smaller exposure — more casual exposure — and then get infected.”
That’s a big problem for young adults, who are more likely to be socializing without being vaccinated.
And it’s hard to tell who may be infected. People can spread coronavirus days before symptoms appear, just by talking or breathing.
All of America needs young adults’ help to stay safe
Refusing the Covid-19 vaccine can impact a lot of people — from individuals to their loved ones to the country as a whole.
And as Americans go back to crowded bars, concerts, sporting events and movie theaters, the need for widespread vaccination becomes even more important.
Second, it’s a mistake to think everyone who wants a vaccine can just get one. “Some people are on cancer chemotherapy. They can’t be vaccinated — they depend on the herd to protect them,” Offit said.
So many of the most vulnerable are counting on their fellow Americans to get vaccinated.
It’s critical to protect children
Right now, vaccines aren’t available to children under 16. But children are still at risk getting and spreading coronavirus, including the B.1.1.7 strain.
And about 11% to 15% of children with coronavirus go on to develop long Covid, said Collins, the director of the National Institutes of Health.
So to anyone who has a child or interacts with children, get vaccinated, doctors say.
It’s also especially important as cases of MIS-C, or multisystem inflammatory syndrome in children, are on the rise.
MIS-C is a condition that happens when “the virus induces your body to make an immune response against your own blood vessels,” Offit said. That can cause inflammation of the blood vessels.
Often, children with MIS-C had coronavirus but only mild or no symptoms.
“Usually children are picked up incidentally as having (Covid-19). Someone in the family was infected, a friend was infected, so they got a PCR test. And they’re found to be positive. … Then they’re fine,” Offit said.
“Then a month goes by, and they develop a high fever. And evidence of lung, liver, kidney or heart damage (problems). That’s when they come to our hospital. … They have an antibody response to the virus,” he said.
For both parents and young adults, “you can’t believe it’s going to happen to you until it happens to you,” Offit said.
“I work at a hospital, and I can tell you there are a lot of people who can’t believe what has just happened to them or to their children.”
He said he had one message for young, healthy people who think they don’t need a vaccine:
“You’re not invulnerable. I know when you’re young, you feel you’re invulnerable. But you’re not.”
