Erin Kissane, a co-founder of the COVID Tracking Project, rolled up her sleeve for the Novavax COVID-19 vaccine in mid-October quickly after it was lastly advisable within the United States. Like many individuals with autoimmune illnesses, she desires to guard herself from a probably devastating COVID an infection.
Kissane’s autoimmune arthritis appears to make her inclined to uncommon vaccine negative effects. After getting an mRNA booster final 12 months, her joints ached so painfully that her physician prescribed steroids to dampen the irritation. She nonetheless considers the mRNA vaccines “miraculous,” realizing COVID may very well be far worse than short-term aches.
Nonetheless, when the ache subsided, she pored by way of research on Novavax’s shot, a vaccine that’s primarily based on proteins reasonably than mRNA and has been used since early 2022 in different nations. Data from the United Kingdom discovered that folks extra often reported short-term reactions — like low fevers, fatigue, and ache — as their immune system ramped up within the days following booster vaccination with Moderna’s mRNA vaccine versus the one by Pfizer. And these boosted with Novavax’s had fewer complaints than both of these. That discovering was corroborated in an evaluation of worldwide information printed final 12 months.
Such research have pushed folks with lengthy COVID and continual fatigue syndrome (also referred to as myalgic encephalomyelitis, or ME/CFS) to hunt out Novavax, too, because the FDA and the Centers for Disease Control and Prevention greenlighted Novavax’s vaccine — up to date to guard in opposition to current omicron coronavirus variants — about three weeks after recommending up to date mRNA vaccines in September.
Waiting paid off for Kissane, whose arm was briefly sore. “It was a dramatically different experience for me,” she stated. “I hope that plays out for others.”
Another group who waited on Novavax are biologists who geek out over its expertise. When requested why he opted for Novavax, Florian Krammer, a virologist on the Icahn School of Medicine at Mount Sinai, replied on X, previously often called Twitter: “Because I am [a] vaccine nerd, I like insect cell produced vaccines.”
Whereas mRNA vaccines direct the physique to supply spike proteins from the coronavirus SARS-CoV-2, which then practice an individual’s immune system to acknowledge and battle the virus, Novavax merely injects the proteins. These proteins are grown inside moth cells in a laboratory, whereas different protein-based photographs use cells from mammals. And Novavax has stated {that a} particular ingredient derived from the bark of Chilean soapbark bushes enhances the vaccine’s energy.
Research suggests that the Novavax vaccine is about as secure and efficient because the mRNA photographs. Its major drawback is arriving late to the scene. Vaccine uptake has plummeted because the first photographs grew to become extensively accessible in 2021. Nearly 70% of individuals received the first vaccines, in contrast with fewer than 20% choosing the mRNA COVID boosters launched final 12 months. Numbers have dwindled additional: As of Oct. 17, solely 5% of individuals within the United States had gotten the most recent COVID vaccines, in keeping with the Department of Health and Human Services.
Daniel Park, an epidemiologist at George Washington University, stated low charges would possibly enhance if individuals who felt awful after their final mRNA photographs gave Novavax a attempt. It protects in opposition to extreme sickness, however researchers wrestle to specify simply how efficient this and different vaccines are, at this level, as a result of research have gotten tough to conduct: New coronavirus variants repeatedly emerge, and other people have fluctuating ranges of immunity from earlier vaccines and infections.
Still, a current examine in Italy means that Novavax is corresponding to mRNA vaccines. It remained greater than 50% efficient at stopping symptomatic COVID 4 months after vaccination. Some information means that mixing and matching various kinds of vaccines confers stronger safety — though different research have discovered no profit.
Given all this, Park held out for the Novavax vaccine on account of its probably milder negative effects. “Between a demanding full-time job and two young kids at home, I wanted to stay operational,” he stated. His arm was sore, however he didn’t have the 24-hour malaise accompanying his final mRNA shot.
Most folks don’t strike a fever after mRNA photographs. Even once they do, it’s transient and subsequently far much less detrimental than many instances of COVID. In truth, most reactions are so minor that they’re onerous to interpret. During scientific trials on mRNA vaccines, for instance, as much as a 3rd of individuals within the placebo group reported fatigue and complications after injection.
People with ME/CFS and lengthy COVID — a probably debilitating situation that persists months after a COVID an infection — have responded to COVID vaccinations in all kinds of the way. Most members with lengthy COVID in an 83-person Canadian examine stated their ranges of fatigue, focus, and shortness of breath improved following vaccination. Inflammatory proteins which were linked to lengthy COVID dropped as nicely.
However, bigger research have but to corroborate the hopeful discovering. Jennifer Curtin, a physician who co-founded a telehealth clinic targeted on lengthy COVID and ME/CFS, referred to as RTHM, stated vaccines appear to quickly irritate some sufferers’ circumstances. To learn the way Novavax compares, she posted polls on X in late October asking if folks with long COVID or ME/CFS felt that their signs worsened, improved, or stayed the identical after Novavax. Most replied: unchanged.
“It’s not scientific, but we need to figure it out since these folks don’t want to get COVID,” Curtin stated. “My patients are all wondering about what vaccine to get right now.”
Adding to the uncertainty, the rollout of Novavax and mRNA vaccines has been bumpy as pharmacies wrestle to foretell demand and insurance coverage firms determine how one can reimburse suppliers for the photographs. Unlike earlier vaccine choices, these choices are now not absolutely coated by the federal authorities. A testomony to this season’s wrestle to get vaccinated is that at the very least one do-gooder has created an internet software to search out open appointments for Novavax.
Buoyed by anecdotes of aid from others with lengthy COVID, Hayley Brown, a researcher on the Center for Economic and Policy Research who has the situation, opted for Novavax lately. Unfortunately, her signs have flared. She stated a short lived discomfort will nonetheless be preferable to risking one other an infection. “As someone with long COVID, the idea of getting COVID again is terrifying.”
