What Is Natural Immunity
Natural immunity is the antibody protection your body creates against a germ once youve been infected with it. Natural immunity varies according to the person and the germ. For example, people who have had the measles are not likely to get it again, but this is not the case for every disease. A mild case of an illness may not result in strong natural immunity. New studies show that natural immunity to the coronavirus weakens over time, and does so faster than immunity provided by COVID-19 vaccination.
Experts React To Pauls Statement
Dr. Julie Parsonnet, an expert in adult infectious diseases at Stanford University in California, says Pauls comments suggest a lack of understanding about the immune system.
I think its a bad message and I think it reflects a lack of understanding of how immunity works. Usually the first exposure to an infection is sort of like a taste test. Your immune system sees it and it responds, but it doesnt build up very strong memory responses and you dont have the circulating cells that allow you to respond very quickly to infection, Parsonnet told Healthline.
We know that some people who have COVID dont mount an immune response at all. We also know that some people get reinfected and that some people who have gotten reinfected have gotten quite sick. Yes, he will have some immunity, but there is good data that you will have better immunity if you get a vaccine, she added.
Dr. William Schaffner is an expert in infectious diseases at Vanderbilt University in Tennessee. He says the recommendation for people who have already had COVID-19 to still get vaccinated is based on two factors.
The first is that the antibody levels after vaccination are much higher than the antibody levels after natural infection. And higher antibody levels are usually associated with a longer duration of protection, Schaffner told Healthline.
When To Get The Additional Shot
Some debate remains about the best time to get a booster shot.
Connick told Healthline that the CDC recommends getting boosted 5 months after completing the initial 2-shot series of the Pfizer or Moderna vaccine, or 2 months after receiving the 1-shot Johnson & Johnson vaccine and as soon as possible after that if youve had COVID-19 but are now feeling well.
I would suggest that individuals wait until the acute symptoms of their breakthrough infection wear off before getting the booster, so as to minimize possible unpleasant side effects from the vaccine, Dr. Richard Parker, the chief medical officer at managed care and medical data firm Arcadia, told Healthline.
Some data out of Canada suggests that waiting a month or two might result in longer protection, but theres still no solid evidence supporting such a delay in getting boosted, said Connick.
If you wait for the booster and you get COVID again, then it wasnt worth the wait, she said. If youre high-risk, youll want to get the booster ASAP.
Waiting until your natural immunity goes away is a problem because we dont know how to track that, Phil Felgner, PhD, the director of the Vaccine Research & Development Center at the University of California at Irvine, told Healthline.
The durability of the COVID-19 vaccines and boosters, on the other hand, has been really remarkable, he said.

Will I Or My Child Get Myocarditis Or Pericarditis From Receiving An Mrna Covid
Myocarditis and pericarditis are two kinds of heart inflammation that can cause symptoms like chest pain, a fast or hard heartbeat, and shortness of breath.
When they happen, they mostly happen in male adolescents and young adults, typically within several days after mRNA COVID-19 vaccination.
Patients usually recover quickly and respond well to medications and rest.
Youre actually more likely to get heart inflammation if youre unvaccinated and get sick with COVID-19. And heart inflammation from COVID-19 tends to be worse than the heart inflammation people have had after vaccination.
Is It Safe To Get The Vaccine If Youve Already Had Covid
Its absolutely safe. The CDC officially recommends that you still get the vaccine if youve already had COVID-19, as it will simply help boost your immunity or ensure that you have complete immunity, says William Schaffner, M.D., an infectious disease specialist and professor at the Vanderbilt University School of Medicine.
Like any other person who receives the vaccine, its possible to experience side effects after getting your dose. Theres no reason to think that the side effects or safety profile would be any different, says Dr. Gonsenhauser. This mainly includes pain, soreness, or swelling at the injection site, a potential fever or chills, and other flu-like symptoms, like a headache, fatigue, and muscle pain.
Also important to remember: Its totally possible you may have no side effects at all. If you do, they should pass within a few days.
Will the vaccine protect you even more if youve already had COVID-19?
OK, so if the vaccine can help ensure your immunity after having COVID-19 and you likely have some immunity already, is it possible that youll have even better results fighting off the coronavirus than someone who has never been infected?
Thats a question medical experts are still exploring. In short: We just dont know yet, Dr. Watkins says.
Bottom line: Whether youve had COVID-19 or not, experts stress the importance of getting vaccinated to ensure you stay protected.

- Use comforting positions, such as holding your child on your lap. Avoid laying your child down flat. And never pin down your child for medical procedures.
What You Need To Know About ‘natural Immunity’
When someone is infected with SARS-CoV-2, the virus that causes Covid-19, their immune system creates antibodies, which are proteins that fight off infections and help prevent future infections from occurring. That is called “natural immunity.”
At this stage, there are still lots of questions about how long natural immunity from Covid lasts and whether it could prevent reinfection, Dr. David Wohl, an infectious disease physician at the University of North Carolina, tells CNBC Make It.
Studies on people who were exposed to Covid and then recovered have shown that their antibodies remained pretty stable, and only dropped “modestly” after six or eight months. Another promising outcome: coronavirus-specific B and T cells also appear to increase and remain high after infection.
New research that hasn’t been peer-reviewed yet found that people who have already had Covid tend to have higher antibody responses after their first dose of the mRNA vaccines than two doses of the vaccine in people who haven’t had it. Some immunologists argue that people who’ve recovered from Covid should only need one dose of a vaccine.
“If you’ve had Covid-19, may augment or help increase the durability, and even maybe the breadth, of your immune response against coronavirus,” Wohl says.

It’s recommended that both of your first two shots of a two-shot series vaccine be the same brand. If your first shot was Moderna, your second shot should also be Moderna, and the same for Pfizer. However, after completing your two-shot series of either Pfizer or Moderna, you may choose to “mix and match” and receive a different brand for your booster shot. Learn more about booster shots here.
Do You Need The Coronavirus Vaccine If You Already Had Covid
If you already had COVID-19, you might be wondering if you should plan to get vaccinated.
Doctors are still looking into how long immunity from natural infection with the coronavirus lasts, but the current thinking is that antibody levels begin to drop after a few months particularly in asymptomatic and milder cases eventually leaving people susceptible to catching the virus a second time.
Though this particular issue needs more research, health experts suspect that people with a recent COVID-19 infection may be able to hold off a few months before getting the vaccine. Those who have been recovered from COVID-19 for several months, however, should plan to get the shot as soon as it becomes available to them.
Heres why, along with some other information you need to know:

When Should You Get A Booster After Covid Infection
Eligible individuals can safely get a booster after a Covid infection as soon as they are no longer contagious. For most people, that’s about 10 days after testing positive or 10 days after first noticing symptoms, Mahaley says. However, there is no hard and fast timeline.
Whether protection is gleaned from infection or vaccination, Chang explains that, when it comes to how long antibodies will last, everyone is different. If you are concerned about getting a booster soon after a Covid infection, Chang says that, If you were recently infected, its reasonable to wait around 3-5 months, as you likely had a boost in antibody levels from the infection.
Another thing to take into consideration where timing of a booster after Covid infection is concerned is what course of treatment, if any, you received while infected. If youve received monoclonal antibodies , it is best you wait 90 days before getting your booster Covid vaccine, Mahaley tells Romper.
Vaccination Is Still Necessary After Covid
While it has been argued that natural immunity is protective against coronavirus reinfection, CDC and many immunologists recommend vaccination regardless of prior infection, the New York Times reports.
So-called “natural immunity,” which is the result of having Covid-19, varies from patient to patient. According to the Times, 85% to 90% of people who recover from Covid-19 have detectable antibodies, but the strength and durability of natural immunity can vary depending on a person’s age, health, and the severity of their initial infection.
For example, research from Akiko Iwasaki, an immunologist at Yale University, and her team found a stepwise increase in antibody levels as a patient’s Covid-19 severity increases. Another study found that around 43% of Covid-19 survivors had no detectable neutralizing antibodiesthe specific type of antibodies needed to prevent reinfection. And a CDC study found that antibodies from natural immunity decrease to undetectable levels in around 30% of Covid-19 survivors after approximately two months.
In addition, most studies of natural immunity against Covid-19 have tracked people for only about a year, said Nabin Shrestha, an infectious disease physician at Cleveland Clinic. “The important question is, how long does it protect, because we’re not under any illusions that this will be a lifelong protection,” he said.

Is It Better To Gain Immunity Through Exposure To Covid
With some viruses, such as chicken pox, being infected with the virus itself grants stronger immune protection than the chicken pox vaccine however, in those cases, you then have to deal with all the complications of having the virus. When it comes to COVID-19, its really hard to know whether being exposed to the virus is more protective of future infection than the vaccine, simply because we dont know the SARS-CoV-2 virus well enough yet.
With natural immunity, which is the protection we get after being infected with a virus, the immune response can be variable. For example: the number of antibodies your body produces may depend on how much of the virus youre exposed to. And there is likely beneficial variation in the types of antibodies being produced. The vaccinations currently available in the U.S. have been shown to effectively stimulate antibodies against the virus spike protein. New vaccines are being created that make antibodies to other parts of the virus as well. Both immunity from natural infection and vaccination stimulate a T-cell response that will hopefully provide you with protection from the virus for a longer time.
On the other hand, we do know that the vaccine is very protective. In most people, getting vaccinated generates a lot of antibodies. So far, the vaccines appear to be incredibly effective, especially when it comes to preventing severe infections, hospitalizations and death.
What Are Some Symptoms Of Covid
People with COVID-19 have reported a wide range of symptoms, ranging from mild symptoms to severe illness. Symptoms may appear 2 to 14 days after exposure to the virus. Symptoms may include: fever or chills cough shortness of breath fatigue muscle or body aches headache new loss of taste or smell sore throat congestion or runny nose nausea or vomiting diarrhea.

A Q& a With Uchicago Medicine Infectious Disease Specialist Jennifer Pisano
The Centers for Disease Control announced that in most cases, vaccinated adults in the U.S. could start going without masks, even indoors a long-awaited benchmark to signal a return to a more normal life. But many people still have lingering questions about the COVID-19 vaccines and whether or not theyre needed, especially if youve already had COVID-19.
Jennifer Pisano is an Associate Professor of Medicine in Infectious Diseases at the University of Chicago. She serves as medical director of antimicrobial stewardship and infection control at the University of Chicago Medicine.
As an infectious diseases expert and someone who contracted COVID-19 myself, Im here to share my insights, said Pisano.
How Much Will It Cost Me To Get A Vaccine
The federal government is providing the vaccine free of charge to all people living in the United States. Vaccination providers can be reimbursed for vaccine administration fees by the patients public or private insurance company or, for uninsured patients, by the Health Resources and Services Administrations Provider Relief Fund. No one can be denied a vaccine if they are unable to pay a vaccine administration fee, and no one should receive a bill for receiving the vaccine.
Anyone who has received their vaccine and has a question about any charges, fees or associated costs should contact their vaccine provider.

Is There Anyone Who Shouldnt Get Vaccinated After Covid
The CDC does note that if you had COVID-19 and received treatment with monoclonal antibodies or convalescent plasma , you should hold off for 90 days before getting the vaccine to be certain it will be effective.
These treatments havent been studied with the vaccine, so you should delay in order to avoid potential interference of the therapies with vaccine responses.
Some people with certain conditions that make them more likely to have COVID-19 may have less protection from the vaccine. This just makes it more important to get the shot.
In some individuals, especially those who are older or who have an underlying disease like cancer, antibody levels following either dose of vaccine may be below the level that provides protection, so it is possible to develop COVID-19 infection, Dr. Middleton says. Still, some protection is better than none.
Can You Still Pass The Virus To Others Even If Youve Been Vaccinated
Researchers are currently studying whether someone whos been vaccinated can carry the virus and pass it on to others.
Its looking like the vaccine actually cuts down on the transmissibility of the virus. So if youve been vaccinated, theres much less likelihood that youre going to get exposed to the virus and be able to pass it on to others.
She clarifies that some of the early data has not been peer reviewed yet, although it has been published. So researchers are still finalizing this information. But she says early research indicates that being vaccinated for COVID-19 can make you 90% less likely to have an asymptomatic infection and transmit the virus to those around you.
It looks like the vaccine truly is not only protecting you, but it is protecting those around you.
