Which Covid Vaccine Has The Least Side Effects

Everyone Should Still Get Vaccinated

Will there be long-term side effects from COVID-19 vaccine?

While the J& J vaccine pause has been lifted, some people might still be worried. But the United States has authorized use of two other safe and highly effective COVID vaccines, which use a completely different platform, said Dr. Fryhofer. Pfizer and Moderna mRNA vaccines are completely different and more than 180 million doses of mRNA COVID vaccines have been administered.

Additionally, there have been no reports of cerebral venous sinus thrombosis combined with thrombocytopenia in patients who have received mRNA vaccines by Pfizer or Moderna, she said, emphasizing that this rare, but deadly combination of blood clots and low platelets has not been seen with Pfizer and Moderna mRNA COVID vaccines.

Fortunately, based on current projections, the supply of both of these mRNA vaccines is fairly high and looks stable for at least the near future, said Dr. Fryhofer, adding that we need to encourage our patients to get vaccinated. This is the only way we can end this pandemic.

Common Side Effects Of Covid Vaccines

After getting vaccinated for COVID-19, you might experience some temporary symptoms similar to those you might notice when you get a flu shot, such as a sore, swollen arm where you got the shot. You might run a fever and experience body aches, headaches and tiredness for a day or two. Chills and swollen lymph nodes can also occur.

These symptoms do not mean you are sick. They signal that your immune system is responding to the shot and building up protection against the coronavirus.

What Are The Potential Side Effects

Side effects are possible after receiving any COVID vaccine currently being administered in the U.S.

Experiencing side effects isn’t necessarily a bad thing. In fact, it’s a sign your body is responding.

“That’s just your immune system learning the lesson of how to fight it off,” Chicago’s top doctor said in a Facebook Live Tuesday. “So people who have stronger side effects, it’s just a sign that you have a very robust strong immune system that’s learning the lesson.”

The CDC reports the most common side effects for the vaccines is at the injection site. They include:

  • Pain
  • Fever
  • Nausea

The Centers for Disease Control and Prevention advises people to stick around for 15 minutes after vaccination, and those with a history of other allergies for 30 minutes, so they can be monitored and treated immediately if they have a reaction.

When To Call The Doctor

Side effects can affect you or your childs ability to do daily activities, but they should go away in a few days.

In most cases, discomfort from pain or fever is a normal sign that the body is building protection. Contact a doctor or healthcare provider:

  • If the redness or tenderness where the shot was given gets worse after 24 hours
  • If the side effects are worrying or do not seem to be going away after a few days

If you or your child get a COVID-19 vaccine and you think you or they might be having a severe allergic reaction after leaving the vaccination site, seek immediate medical care by calling 911. Learn more about COVID-19 vaccines and rare severe allergic reactions.

The CDC Is Now Investigating This New Delayed COVID Vaccine Side Effect

Sandra Trevino, LCSW, is a founding member of Yales Cultural Ambassadors programa 10-year-old organization whose mission is to broaden community participation in clinical trials at the Yale Center for Clinical Investigationand is doubling her efforts to help educate people about COVID-19 vaccines.

In December, the Kaiser Family Foundation released results of a survey in which more than one-quarter of Americans said they would probably or definitely not get the vaccine. Republicans, and rural and Black Americans were most hesitant, according to the survey.

Its a great responsibility to make sure we continue to address the elephant in the room, which is mistrust with regard to the vaccines, says Trevino.

In a recent interview, she explained why shes encouraging everyone to get the COVID-19 vaccine and talked about her own familys experience with COVID-19.

Johnson & Johnson And Guillain

Guillain-Barré syndrome is a rare neurological disorder in which the immune system attacks the nerves. It can cause muscle weakness and sometimes paralysis. People usually recover from it, but it can lead to hospitalization and, sometimes, permanent damage to nerve cells.

So, its not surprising that people have questions upon hearing that about 100 suspected cases of GBS have been identified among 12.8 million people who have received the Johnson & Johnson vaccine. While this figure is low enough to categorize the occurrences as rare, the Food and Drug Administration has now attached a warning to the Johnson & Johnson shot about the increased risk of developing GBS in the 42 days after vaccination.

Q & A With A Vaccine Expert

We spoke with Saad Omer, MBBS, PhD, MPH, director of the Yale Institute for Global Health, to get answers to the hard questions on the safety and efficacy of the COVID-19 vaccines in development. The shortened timelines surrounding the development of these vaccines, coupled with concerns over what some feel is undue political influence over the release of them, is concerning to many Americans.

We sat down with Dr. Omer, who addresses these concerns.

Murdoch Childrens Research Institute

The Murdoch Childrens Research Institute is running a Phase III trial repurposing Bacillus Calmette-Guerin a vaccine developed nearly a century ago to prevent tuberculosis infections to prevent Covid-19. Since the vaccine has been around such a long time, there are many reports on its potential adverse effects and the vaccine itself has beenaltered to minimize many of them. Injection site reactions are common, and lymphadenitis, swelling of the lymph nodes, is common.

The Vaccine Development Process From Clinical Trials To Ongoing Monitoring Helps To Uncover And Understand Side Effects

CDC plans ’emergency meeting’ over COVID-19 vaccine side effects

Clinical trials are a key part of vaccine development and involve evaluating use in tens of thousands of study participants. All of the COVID-19 vaccines went through this rigorous process before authorization.

In reviewing results from the trials, the federal Food and Drug Administration must determine that the known and potential benefits outweigh the known and potential risks of the vaccine.

After vaccines are authorized and in use by the public, public health officials continue monitoring the data as an additional safety measure. Manufacturers must have a plan to report follow-up data, including any events such as hospitalizations and deaths, and they must continue research to generate more data on safety and efficacy.

Mix And Match Boosters

It appears getting a booster shot is going to be a choose your own adventure type of experience after the FDA stipulated that people eligible for boosters can choose any of the jabs, regardless of what brand they initially received.

There is a growing body of evidence that boosting with a different vaccine could induce a broader and longer-lasting immune response though some combinations may work better than others.

In announcing the emergency authorizations for the Moderna and J& J boosters, the FDA stated no preference for who gets what, or in what order. People who got J& J can get a second shot of Moderna or Pfizer. People who got one of the mRNA vaccines can get the J& J vaccine as their booster, the agency said.

Not stated in the FDAs announcement is the fact that this new policy will make life much easier for folks delivering booster shots, especially those trying to boost people living in long-term care, homeless shelters or prisons. They will need to bring only one vaccine when they go to administer booster shots, rather than trying to match people to their original vaccination brand.

What If I Have Breast Cancer Or A History Of Breast Cancer

Some people who get a COVID-19 vaccine might have swollen lymph nodes under the arm in which the injection was given . Because a swollen lymph node under the arm can also be a sign of breast cancer spread, most doctors recommend that people with breast cancer or a history of breast cancer get the injection in the arm on the opposite side of your breast cancer. For example, if your breast cancer/breast surgery was in the left breast, it is probably best to get the injection in the right arm. If you have had surgery on both breasts, its best to talk with your doctor about the best place on your body to get the injection.

Swollen lymph nodes after a vaccine injection might also have an effect on your mammogram results.

The Johnson & Johnson Vaccine And Blood Clots: What You Need To Know

In the minds of many, the halt of the Johnson & Johnson vaccine in April delivered doubt just as the mass COVID-19 vaccinations were making progress. There are three vaccines authorized for use in the United States, but Johnson & Johnsons was a particularly important one, partly because its one-shot dose made it seem as though we might achieve herd immunity faster. Then, the government recommended pausing the companys vaccine after six women who received it developed rare blood clotsand one woman died.

We spoke to Yale Medicine infectious diseases expert Jaimie Meyer, MD, MS, and Yale Medicine hematologist Robert Bona, MDthey shared insights about the pause and answered commonly asked questions.

CDC Warns of These COVID Vaccine Side Effects

Stem cell transplants and CAR T-cell therapy are types of cancer treatment that can have major effects on the bodys immune system. This can increase your risk of serious infections .

If youve already received one of these cancer treatments in the past, the CDC still recommends getting the COVID-19 vaccine. This might include an additional dose of vaccine , as well as a booster dose. Many doctors recommend waiting at least 3 months after these cancer treatments before getting the vaccine, to give the bodys immune system a chance to recover.

If youve already gotten the COVID-19 vaccine and are now getting one of these cancer treatments, the CDC recommends getting revaccinated at least 3 months after treatment. This is because the immune system needs to relearn how to protect the body against COVID-19.

If youre getting one of these cancer treatments, its important to talk to your doctor about your immune status, when you should get the vaccine, and if you should get additional doses of the vaccine, as well as what else you can do to help lower your risk of infection.

Trusted Sources Of Information

As previous KFF research has shown, pediatricians remain the most trusted source of information on the COVID-19 vaccine for parents. About three in four parents say they trust their childs pediatrician or health care provider to provide reliable information about the vaccines for children. Across partisans and across race and ethnicity pediatricians are the most trusted source of vaccine information for parents. About six in ten parents say they trust their local public health department and the CDC to provide reliable information about the COVID-19 vaccines for children, though there are large partisan differences with Republicans less likely than Democrats to trust either of these as sources of information. Parents trust in the CDC for information regarding vaccines for children has decreased since July when two-thirds said they had at least a fair amount of trust in the CDC to provide reliable information.

Reaching unvaccinated parents with information about the COVID-19 vaccine for children is likely to be a challenge as they are less likely than their vaccinated counterparts to trust each of the sources of vaccine information tested. Only pediatricians are trusted by a majority of unvaccinated parents to provide reliable information about the COVID-19 vaccine for children, while fewer than half of unvaccinated parents trust the CDC, their local public health department, their childs school or daycare, or other parents they know for such information.

Should I Get The Flu Vaccine As Well

COVID-19 and influenza are caused by different viruses, so getting a vaccine against one of these diseases will NOT protect against the other. Along with talking to their doctor about getting the COVID-19 vaccine, its very important for cancer patients talk to their doctor about the benefits and risks of getting the flu shot.

The flu and COVID-19 are both caused by viruses that can spread easily and can cause serious illness in older people, those with weakened immune systems, and others with certain medical conditions. These infections share many of the same symptoms, so it can be hard to tell which one you might have without having specific tests.

People who live with or care for someone at high risk of getting the flu should also get the flu vaccine.

The overlap of this years flu season on top of the COVID-19 pandemic could also put a burden on healthcare systems, so getting the flu vaccine could help lessen this.

The CDC has more information on the differences between COVID-19 and the flu, as well as more information about getting the flu vaccine.

Should You Still Choose The J& j Vaccine

The CDC says the benefits of getting the vaccine still outweigh the threat of being infected with the coronavirus.

As more people are vaccinated, fewer will become infected, and that could slow the spread of the virus, resulting in better protection for everyone. While no vaccine guarantees 100% protectionand there is more to learn about vaccine effectiveness against Omicronso far, all three COVID-19 vaccines have been very effective at preventing serious illness and death.

If you got J& J as your initial vaccine and are 18 or older, you are eligible for a booster shot two months later, regardless of which one you choose . Those ages 16 and 17 are eligible to get the Pfizer-BioNTech booster.

The Cdc Recommends Boosters For All Adults And Allows You To Mix And Match

Some Children Reporting Rare Side Effects From COVID-19 Vaccine

The CDC now recommends booster shots for all Americans ages 16 and older. People who received two doses of Pfizer’s or Moderna’s vaccine should get boosted at least six months after their second shot, the CDC advises, whereas J& J recipients can get boosted as early as two months after their first dose.

The CDC has also approved a “mix and match” approach so people can select a booster of a different vaccine type or different manufacturer than their original dose.

An funded by the US National Institutes of Health found that mix and match boosters yielded similar side effects to initial vaccine doses. More than half of the study’s 458 participants reported malaise, headaches, and muscle aches after their booster while more than 70% experienced mild arm pain.

A UK study similarly identified fatigue, headaches, and pain at the injection site as the most common side effects. The study looked at nearly 2,900 people who had received two doses of Pfizer or AstraZeneca, followed by one of seven different COVID-19 boosters. Overall, side effects from boosters were more common in people ages 30 to 69 than those ages 70 and up, the study found regardless of which vaccines the participants received.

But since the J& J vaccines arrival on the scene it has faced a number of challenges. A production snafu in the hands of a contract producer contaminated 15 million doses, which had to be destroyed. In mid-April, the FDA and CDC paused use of the vaccine as they investigated whether it triggered a rare but dangerous side effect diffuse blood clots that formed even though affected people had low levels of clot-forming platelets. Continuing concern about that condition, called thrombosis with thrombocytopenia syndrome, or TTS, led the CDC on Dec. 16 to advise people to choose Moderna or Pfizer over the J& J vaccine.

What follows is a head-to-head comparison of the vaccines developed by Pfizer and BioNTech, by Moderna, and by J& J. This article will be updated as developments occur.

Fewer Side Effects May Encourage People To Get Vaccinated

Vaccine side effects can be an important factor affecting whether people get the jab.

According to the Kaiser Family Foundation, nearly half of unvaccinated adults worry about missing work if the vaccine’s side effects make them feel sick for a day or more.

Lower rates of vaccine side effects are important, in particular for adults who are concerned about lost wages or unscheduled time away from work, Tanjala Purnell, PhD, assistant professor of epidemiology at the Johns Hopkins Bloomberg School of Public Health, tells Verywell. On average, hourly-wage workers often earn less overall income as compared with salaried workers. Therefore, these clinical trial results may be especially appealing to people who have concerns about loss of income due to sick days or potential time away from work due to vaccine side effects and/or complications.

If a vaccine like Novavax that causes fewer or less severe side effects becomes available, vaccination rates may increase among people in lower-income communities who can’t afford to miss a days worth of pay. According to recent Census Bureau data, more than half of unvaccinated Americans live in households that make less than $50,000 annually.
