Do You Have To Get The Covid Vaccine Every Year

What Does Fully Vaccinated Mean

Will you have to get the COVID-19 vaccine every year?

According to CDC guidelines, you are fully vaccinated when it has been:

  • Two weeks after your second dose in a two-dose series, such as the Pfizer or Moderna vaccines.
  • Two weeks after a single dose of the Johnson & Johnson vaccine. However, data from clinical trials are clear that there is further improvement four weeks after the single-shot vaccine, especially for preventing severe COVID-19 or having asymptomatic infection. For this reason, Johns Hopkins Medicine recommends four weeks after the single-dose vaccine to be considered fully vaccinated.

If you dont meet these requirements, you are not fully vaccinated.

Access To The Vaccine

Q. How can I get the vaccine in DC?

A. It is easy to get the vaccine now! All DC residents 5 and older are eligible to receive the COVID-19 vaccine, however for children 5-11, the only authorized vaccine is the pediatric dose of the Pfizer vaccine. To find a COVID-19 vaccine, search,, or text your Zip Code to 438829. If you are unable to leave your home, call 1-855-363-0333 and we’ll come to you.

Will 1 Or 2 Booster Shots Be Enough

Ali Ellebedy, an associate professor of pathology and immunology at Washington University School of Medicine, said he has found that, six months after a second dose of an mRNA vaccine, immune response is still maturing.

“There is an ongoing reaction in our lymph nodes that’s going for six months,” Ellebedy said. “And that reaction, we are showing, that it is actually enhancing the potency of the antibodies. Even before the third dose.”

That maturation would be accelerated by a third dose and could lead antibodies to improve through a process called affinity maturation, in which the antibodies get better at recognizing their target, even if the virus changes, STAT News reports.

“If you wait six months or more between a priming and boost, what you see is not just a boosting of the immunity that you got from the first vaccine, but you see a broadening of the immune response so that it recognizes other viruses or other variants,” said David Topham, an immunologist at the University of Rochester Medical Center and director of the New York Influenza Center of Excellence. “Your immune response becomes much more cross-protective.”

Barney Graham, an immunologist and former deputy director of NIH‘s Vaccine Research Center, said he’s found in his research that antibodies induced by delayed booster shots are higher quality and generate a broader immune response that’s better at recognizing mutated viruses.

Preparing For Your Vaccine

You can get a COVID-19 vaccine and other vaccines, including a flu vaccine, at the same visit. Experience with other vaccines has shown that the way our bodies develop protection, known as an immune response, and possible side effects after getting vaccinated are generally the same when given alone or with other vaccines. Learn more about the timing of other vaccines.

You should get a COVID-19 vaccine even if you already had COVID-19.

Getting sick with COVID-19 offers some protection from future illness with COVID-19, sometimes called natural immunity. The level of protection people get from having COVID-19 may vary depending on how mild or severe their illness was, the time since their infection, and their age. No currently available test can reliably determine if a person is protected from infection.

All COVID-19 vaccines currently available in the United States are effective at preventing COVID-19. Getting a COVID-19 vaccine gives most people a high level of protection against COVID-19 even in people who have already been sick with COVID-19.

Emerging evidence shows that getting a COVID-19 vaccine after you recover from COVID-19 infection provides added protection to your immune system. One study showed that, for people who already had COVID-19, those who do not get vaccinated after their recovery are more than 2 times as likely to get COVID-19 again than those who get fully vaccinated after their recovery.

When Does It Start Working

COVID vaccine, explained: Pfizer FDA approval, side effects, Moderna

The Pfizer vaccine is given in two doses scheduled three weeks apart. It’s not ideal but, according to the Centers for Disease Control and Prevention , the second dose may be given up to 6 weeks after the first dose, if necessary. You should not get the second dose early.

These doses are given as injections and offer full protection two weeks after the second dose, the CDC says. The data suggest that after the first dose, some immune response is present in about two weeks.

A CDC report that tracked almost 4,000 healthcare personnel, first responders, and other frontline workers under real-world conditions found that the mRNA vaccines were 80% effective at least 14 days following the first dose and 90% effective at least two weeks after the second dose.

How Can I Protect My Children If They Cant Get The Vaccine

COVID-19 vaccines currently are not approved in people under age 5. There is some evidence that other vaccines, specifically MMR and Pneumovax, can help protect against COVID-19. These are routine pediatric vaccines. Check with your pediatrician to make sure your children are up to date on their vaccinations, and if they are not, talk to your health care provider about catching up on these vaccines.

Special Populations

How Long Does Covid

Right now, vaccines appear to trigger an immune response that lasts longer than natural infection, according to Andrew Pavia, MD, an infectious disease specialist at University of Utah Health, in an interview with Rochester First. That means vaccine-conferred immunity “may last longer than a year,” he said, “but it’s unlikely to be permanent the way two doses of measles vaccine is.” Dr. Pavia said it’s likely that “at some point” we’ll need to receive another COVID-19 vaccine we don’t know exactly when or how often. There’s just not enough data yet to know exactly how long immunity lasts.

However, scientists are already working to answer that question. According to The New York Times, researchers will likely track vaccinated people to see who comes down with COVID-19 even after receiving a vaccination. Both the Pfizer and Moderna vaccines are over 94 percent effective at preventing COVID-19 and Johnson & Johnson is 66 percent effective, meaning that some “breakthrough cases” are possible no matter which vaccine you receive. If vaccinated people start getting sick, that’s a sign that protection is getting weaker, which tells scientists about how long the vaccine remains effective. Scientists will also monitor levels of antibodies and T-cells in the blood of vaccinated people to see if and when another shot is required.

Will you have to get a COVID-19 vaccine shot every year?

People with chronic kidney disease at any stage and those who have a weakened immune system from a kidney transplant should understand they are at increased risk of severe illness from both COVID-19 and the flu. These individuals need to take precautions such as vaccinations and other measures to help prevent infection.

We May Have To Get The Covid

Getting the flu shot has become an annual tradition for many of us, providing yearly protection from a virus that has killed an estimated 12,000 to 61,000 Americans every year since 2010, according to the CDC. Yearly shots are the norm for the flu, but for other dangerous diseases, such as measles, just one or two shots can provide lifelong protection. The big question in 2021: where does the COVID-19 vaccine fall? Will one or two doses be enough to last for a lifetime, or at least several years? Or will COVID-19 become the “new flu shot,” requiring a dose every year?

Is It Better To Get The Flu Than The Flu Vaccine

No. The flu can be a serious disease, particularly among young children, older adults, and people with certain chronic health conditions, such as chronic kidney disease at any stage including patients on dialysis and kidney transplant recipients who have weakened immune systems. All flu infections carry a risk of serious complications, hospitalization, or death, even among otherwise healthy children and adults. Therefore, to obtain immune protection, getting vaccinated is a safer choice than risking severe illness.

None of the approved vaccines will be hard to tweak if needed for a new variant, Dr English said.

However, whether that can be approved quickly depends on whether the regulators accept tweaks, as they do for the flu vaccine every year, or if each vaccine change has to go through the full regulatory process, which can take years.

Can I Still Get Covid

The COVID-19 vaccines are highly effective against serious illness and death, but no vaccine is 100% effective.

A number of vaccinated people may get infected with COVID-19, which is called a breakthrough infection. In such cases, people are much more likely to only have milder symptoms. Their protection against serious illness and death remains strong.

With more infectious virus variants such as Delta, there have been more breakthrough infections. Thats why it’s recommended to continue taking precautions such as avoiding crowded spaces, wearing a mask and washing your hands regularly, even if you are vaccinated.

And remember, if your vaccination involves two doses, its important to receive both to have the maximum protection.

If you have been fully vaccinated but are showing symptoms of COVID-19, you should contact your doctor about whether you should get tested.

How Will I Know When To Get My Second Dose

After receiving your first shot, you will receive a paper immunization record that will be completed at the time of vaccination. It will include the vaccine you received, date and location, and date when your next shot is needed. Individuals will be reminded when its time to receive their second shot.

The vaccine you receive and when you need the second dose is confidential health information that is carefully managed to protect your privacy.

The Pfizer-BioNTech vaccine requires two shots 21 days apart. The Moderna vaccine requires two shots 28 days apart. You must receive both shots of the same type of vaccine: either two shots of Pfizer or two shots of Moderna. The Janssen vaccine only requires one shot.

Everyone 18 and older is also recommended to get a booster shot of COVID-19 vaccine. Learn more about booster shots and third shots for immunocompromised individuals here.

Doctor predicts youll have to get a COVID-19 shot every year

While there have been reports of severe allergic-type reactions in a very small number of patients, the CDC says that people with allergies to certain foods, drugs, insects, latex and other common allergens can still get the COVID-19 vaccine.

If you have had a severe allergic reaction to injectables or other vaccines, be sure to discuss the COVID-19 vaccination with your doctor, who can evaluate you and assess your risk. The vaccine provider should observe you for 30 minutes rather than the routine 15 minutes after vaccination, and if you have an allergic reaction to the first shot, you may not receive the second.

The CDC says that at this time, anyone who has a severe allergy to any of the vaccine ingredients should not get that vaccine.

Who Should Be Vaccinated First

Each country must identify priority populations, which WHO recommends are frontline health workers and those at highest risk of death due to COVID-19, such as older adults and people with certain medical conditions. Other essential workers, such as teachers and social workers, should then be prioritized, followed by additional groups as more vaccine doses become available.

Children and adolescents tend to have milder disease compared to adults, so unless they are part of a group at higher risk of severe COVID-19, it is less urgent to vaccinate them than these priority groups.

Will The Current Covid

At the moment, it appears that COVID-19 is going to continue to be a rapid mutator. For example, Omicron is the most heavily mutated version of the virus we have seen to date and early evidence suggests it has a higher reinfection risk. However, scientists say it will take about several weeks before it is known how the variant impacts on the effectiveness of vaccines.

“If we do not get the global community vaccinated at a high percentage, we continue to risk giving the virus the opportunity to find unvaccinated populations and drive mutation rates. That may mean we need to occasionally alter our vaccines to keep up with the viral changes,” says Rohde.

“However, we may also find that the vaccines continue to protect us. For example, the current data appear to show that many of the existing vaccines have protected us from the Delta variant, at least from the standpoint of high mortality and severe disease that puts people in the hospital.”

Again, however, we will have to wait to see whether COVID-19 boosters are required annually. “We must follow the science in real time to answer these questions in the best way. It could also mean that certain geographical regions may need altered vaccines while others may not,” says Rohde.

“We also desperately need not only higher acceptance of vaccines and boosters, but also vaccine equity for global protection. Without vaccine equity, we will have major pockets of unprotected populations which allows ongoing virus mutations.”

How Booster Shots Strengthen Immunity


Booster shots basically build on the immunity given in the original COVID-19 immunization series.

After we get immunized, then we have the memory T cells that are created that are circulating, and if we expose them to the antigen again then this will result in them multiplying and them forming more antibodies and more cells. And so thats what results in the additional protection, Dr. Dean A. Blumberg, chief of pediatric infectious diseases at the University of California, Davis, told Healthline.

For those 65 years of age and older, the immunity dose wanes starting at 6 months, so there is an increasing rate of hospitalization with the breakthrough infections, he explained. However, we do know that the immune memory remains strong, and thats why giving one additional dose does result in a very robust immune response.

Both Schaffner and Blumberg say its too early to tell how frequently boosters may be required.

However, a COVID-19 shot may need to occur at some frequency for years into the future.

Were learning as we go along. None of us would be surprised if there would be a need for boosters at some interval. Would it be a year, 2 years, 5 years? We dont know, Schaffner said.

He says that in anticipation of boosters being necessary, vaccine scientists are already beginning to combine the influenza vaccine with COVID-19 vaccination.

If the recommendation is there be an annual booster, they would have a combination vaccine ready to go at that time, he said.

What Do Scientists Predict About The Need For Regular Covid Vaccines

Professor Daniel Altmann, an immunologist at Imperial College London, isnt so sure boosters will be needed every year. Many, including Matt Hancock, seem to be talking about annual boosters from autumn, both to keep immunity high and in case of new vaccine versions against variants, he tells HuffPost UK.

Im less convinced this is a certainty. I wonder if theres some confused thinking, that this is going to pan out like seasonal flu vaccination.

The existing Covid vaccines are really potent, he says, and from the data hes seen, hed expect any fully vaccinated person to be protected for two years at the very least.

Then, in terms of currently known variants, the current evidence again is that anyone who receives two vaccine doses has sufficient cover, he explains.

With the latest variant B1617.2, which originated in India studies suggest theres some variation in how well vaccines work against it. The overall takeaway is after two doses, most people should have pretty good protection.

Over your lifetime, you lay down an immune memory.
