As Covid’s omicron variant continues to tear throughout the United States, inflicting report numbers of infections and hospitalizations, new coronavirus myths preserve effervescent up.
The variant has been the topic of fixed scientific scrutiny because it was first detected in South Africa in late November. Recent research have unveiled its strengths and weaknesses: It’s 4 occasions extra transmissible than the delta variant, it causes much less extreme bodily signs than earlier variants, and Covid boosters considerably improve your safety towards it.
In whole, the World Health Organization has collected information from greater than 5,800 research surrounding Covid-19 from everywhere in the world. But regardless of the info, pandemic falsehoods are nonetheless circulating — and omicron appears to have given a few of them new life.
CNBC Make It requested a trio of main infectious illness specialists for the most important Covid misconceptions they’re listening to proper now. Here’s what they mentioned:
Myth: Vaccines do not work as a result of vaccinated individuals are catching omicron
It’s true that vaccinated folks can catch omicron: A two-dose routine of Pfizer’s Covid vaccine solely gives 22.5% safety towards symptomatic an infection from omicron, in accordance with an early examine from South Africa final month.
But crucially, the examine noticed, getting vaccinated helps preserve your signs gentle should you do get sick, lowering your possibilities of hospitalization or demise. And should you add a booster shot, your safety towards symptomatic an infection rises considerably to 75%, in accordance with real-world information from the U.Ok.
“The vaccine does work, and that’s been clearly shown by both death rates and hospitalization rates when comparing vaccinated people to unvaccinated people,” says Dr. Mark Sawyer, an infectious illness specialist at Rady Children’s Hospital who served on the U.S. Food and Drug Administration advisory committee that accepted Covid vaccines in 2020.
Not all states publicly monitor sufferers’ vaccination standing in hospitals, however the ones that do again up Sawyer’s claims.
According to information compiled by Time, unvaccinated folks account for a big share of hospitalized Covid sufferers in states like South Carolina, Montana and Mississippi. And latest information from New York State discovered that unvaccinated residents had a 13-times greater danger for hospitalization than vaccinated residents amid the state’s omicron surge in late December.
That’s as a result of the vaccines immediate your physique to provide an arsenal of Covid-fighting immune cells that work collectively to fend off the virus. Antibodies, which assist forestall you from getting sick, are solely the primary line of protection: If you do get contaminated, your physique’s vaccine-induced T cells goal and destroy virus-infected cells to make your signs much less extreme.
Dr. David Hirschwerk, an infectious illness specialist and medical director at Northwell Health’s North Shore University Hospital, says he continuously reminds folks that the “value of the vaccine” extends to lowering extreme sickness and hospitalizations.
“Hopefully, we can keep reminding ourselves about that fact,” he says.
Myth: Omicron infections are too gentle to be harmful
Dr. Shaun Truelove, an infectious illness epidemiologist on the Johns Hopkins Bloomberg School of Public Health, says he is seen a number of portrayals of omicron as “super mild” and “flu and cold-like.”
While omicron’s bodily signs can typically resemble the flu or frequent chilly, its fee of transmission is far greater. It’s extra transmissible and higher at evading current antibodies than earlier Covid variants, too.
In different phrases, Truelove says, omicron is much extra extreme than the chilly or influenza. And it is the rationale hospitals throughout the nation have gone into emergency mode in latest weeks, declaring they’re at full capability, he provides.
“Even if it’s same severity [of symptoms], it produces — in terms of numbers — way more hospitalizations and deaths,” he says. “I think people keep missing that point.”
Additionally, omicron remains to be a type of Covid. If you catch it, even when your signs are gentle, you are still enabling the virus to maintain circulating — and the extra Covid spreads, particularly in unvaccinated populations, the extra possibilities it has to probably mutate into one other harmful variant.
Myth: There are nonetheless many unknowns about long-term Covid vaccine security
It’s been greater than a 12 months for the reason that first Covid vaccine was administered within the U.S. Since then, almost 250 million folks throughout the nation have obtained a minimum of one vaccine dose, in accordance with the Centers for Disease Control and Prevention.
Yet Sawyer says a lot of the nation’s unvaccinated inhabitants remains to be involved about “what we might not know about these vaccines,” notably when it comes to long-term security.
“We have given hundreds of millions of doses of these vaccines, including in young children, five to 11,” Sawyer says. “So if there was some mysterious side effect that was going to emerge, we would see it by now and know about it.”
Long-term vaccine unwanted effects are extraordinarily uncommon. For instance, J&J’s one-shot vaccine carries a really small danger of “thrombosis with thrombocytopenia syndrome,” a extreme blood clotting dysfunction. Pfizer and Moderna’s mRNA vaccines can improve the chance of myocarditis, a coronary heart irritation situation, in males underneath age 29 — however these instances are sometimes gentle, sometimes resolving on their very own.
For Sawyer, the vaccine’s advantages tremendously outweigh its dangers. As of Friday, roughly 63% of the U.S. inhabitants is absolutely vaccinated, in accordance to the CDC. Of these absolutely vaccinated, roughly 38% have obtained a booster dose, which specialists say is vital in defending your self towards omicron.
