Can I Get Covid Vaccine While I Have Covid
Last week, our colleague at MedPage Today got her booster shot. She was ready for the vaccine'southward side effects -- fatigue, aches, maybe even a fever. What she didn't expect was a sickness that would terminal for days, and a positive rapid antigen test for COVID-19.
In retrospect, it made sense. She remembered a tickle in her throat the mean solar day of her booster shot, but she had just figured it was her torso'southward response to a decorated weekend. Later deciding to become tested, she found out she'd been in contact with someone who had tested positive.
Thankfully, it appeared to be a balmy infection. Just what happens when someone gets a booster shot when they are already infected with SARS-CoV-2? MedPage Today talked to communicable diseases and microbiology experts to find out.
Whether you become inadvertently infected with the virus right earlier or right later getting boosted, an infection may cause symptoms, but isn't likely to interfere with the booster's effects, said Amesh Adalja, MD, an infectious disease physician at Johns Hopkins Schoolhouse of Public Health in Baltimore.
"I doubtable it's non going to be a major consequence other than that you might be contending with more symptoms from the vaccine and from the infection that you lot have at the same time," he said. "It could be more unpleasant than normal."
In fact, your chances of getting infected with SARS-CoV-two are almost every bit high up to six days after getting a booster shot as with no booster, according to a study published in JAMA Internal Medicine. "If you only got your booster a day ago, and then you might as well non accept it at all," said Benjamin tenOever, PhD, a professor in the microbiology section at NYU Grossman Schoolhouse of Medicine.
When going in for a booster shot, vaccination site staff may ask if you're feeling symptoms of COVID-nineteen. This isn't considering the infection and the booster collaborate, but rather to protect everyone at the vaccination site. Still, Simone Wildes, Physician, an infectious affliction medico at South Shore Health in S Weymouth, Massachusetts, said that while an infection close to or around the time of vaccination isn't uncommon or particularly harmful, information technology makes more sense to wait until antibody levels fall after an infection, and then become a booster.
The CDC initially recommended waiting 90 days after an infection to get vaccinated. But guidelines have since inverse to reduce the chances that someone might skip the vaccine or booster altogether after waiting, she said. Co-ordinate to the updated guidelines, "People with COVID-19 who have symptoms should wait to be vaccinated until they have recovered from their illness and have met the criteria for discontinuing isolation."
Despite both the infection and vaccine potentially leading to symptoms that occur in response to a virus, the immune response to a vaccine, including the booster, and the immune response to the virus itself are different processes.
Immune Response to mRNA Vaccines
After receiving a first inoculation, a few cells in the trunk will pick upwards the injected mRNA, and begin to run what tenOever compared to a software program to produce the spike glycoprotein characterizing SARS-CoV-two. Antigen-presenting cells "are going to run into this very foreign-looking structure on the surface of muscle cells in your shoulder and they're going to manage a response to information technology, and that response takes some time," he said.
In those ii to 3 weeks in which the immune response post-vaccine grows stronger, "antigen-presenting cells volition teach your immune arrangement how to recognize this foreign protein, which in this case, is spike," he added.
The mRNA that went into your arm too teaches the immune system to recognize the foreign fasten protein in musculus cells, via immunoglobulin G -- but not in the mucosa, where it would use immunoglobulin A. Without this mucosal immunity, tenOever explained, SARS-CoV-2 tin infect the upper respiratory system after exposure to the virus, but for the virtually role, can't become any further in a vaccinated person.
Immune Response to SARS-CoV-two
If you are infected right around the time of the booster, non only are you lot missing mucosal immunity, but you as well lack the reward of the learning process the immune cells undergo in the weeks following vaccination. "The longer the time between your booster and seeing an actual virus, the better off you are, because you've given your immune system that much more time to explore different spaces and ways to cease the virus," tenOever said.
But if y'all do happen to become an infection and recover, the allowed learning process is refined in a way that the mRNA vaccine tin't induce. "When you get infected, what happens is the virus manifestly now starts killing cells and destroying cells and making a giant mess and losing lots of inflammation. Merely it as well allows your immune system to recognize other components," he noted, such as nucleocapsid poly peptide, which is inside the virus, unlike the fasten proteins.
How to Tell the Difference Between the Ii
Adalja said that though fever, muscle aches and pains, and headaches tin can come up with both immune response scenarios, vaccine side effects are distinguishable from the symptoms of a quantum infection -- to an extent.
"Upper respiratory symptoms would exist ane clue," Adalja explained. These include a sore throat, congestion, and the loss of taste and odour.
"And and so the other aspect would be if it'south prolonged," he added. While side furnishings from the booster may merely last a solar day or two, a long stretch of disease likely ways an infection.
"That's the primal thing," said Wildes. "If you're having the symptoms for more than 72 hours, so we strongly recommend that you reach out to your healthcare provider and become tested, considering it shouldn't be going beyond that point with the vaccine for nigh people."
Hybrid Immunity
Because the trunk builds such a robust response system after infection, amnesty from infection tin be highly protective -- simply is even more so with vaccination. In a written report in Nature, researchers constitute that vaccinated people with previous infection amend neutralized SARS-CoV-2 than did their vaccinated counterparts with no previous infection. A preprint written report out of Israel suggested that hybrid immunity may last longer than vaccine-induced immunity, but both decline over time.
Then, how long does hybrid immunity fend off reinfection? "If [natural amnesty] happened with a Delta variant, information technology may not exist sufficient against the Omicron variant. Simply then again, the booster might not exist sufficient confronting it either," said Adalja. "So, I think that'due south an open question."
If it was the case that you lot got enough immunity from a natural infection alone, then we wouldn't be advocating for vaccines in these individuals as well, noted Wildes. "It'southward not well sorted out considering what happens is, unlike people develop different levels of antibodies."
What to Wait
In any case, an infection that occurs before a booster shot has time to build upward the body's total defenses would probable be mild. This, of form, depends on other factors: historic period, comorbidities, and immunocompromised condition. It is yet possible to get a serious disease, and to spread the virus to others, experts said.
The lesser line is developing a breakthrough infection right earlier or right after a booster shot is possible, and the resulting hybrid amnesty confers some actress protection. And, equally with all responses to the virus, it varies from person to person.
But the most of import thing, experts emphasized, is to get vaccinated in the first identify, and to get a booster when advisable.
"Just get your booster," said Wildes. "I want to make sure that the word gets out that the information are articulate: the two-dose vaccine is non going to be constructive against the Omicron variant, which is already here."
