How Long Do Moderna COVID-19 Vaccine Side Effects Last? | Healthline

The J& J/Janssen COVID-19 vaccine also contains a piece of a modified virus that is not the virus that causes COVID-19. This modified virus is called the vector virus. The vector virus cannot reproduce itself, so it is harmless. This vector virus gives instructions to cells in the body to create an immune response.

Help Identify And Minimize Mild Side Effects

Read the vaccine information that came with your scheduling invite to refresh your knowledge about side effects.

  • Use an ice pack or cool, damp cloth to help reduce redness, soreness and/or swelling at the place where the shot was given.
  • A cool bath can also be soothing.
  • Drink liquids often for 1-2 days after getting the vaccine.
  • Take an over the counter pain reliever unless you have any specific contraindication.

For symptoms that are severe or last 72 hours or more contact your regular clinician or Primary Care Provider.

When To See A Pharmacist

A pharmacist can help determine whether over-the-counter medications are safe and appropriate for each person, and if so, which are the best options.

They consider a persons health history and make sure that any over-the-counter products will not interact with other medications. In addition, a pharmacist can recommend home remedies and advise about whether to contact a doctor. They can also explain how to use a medication, how it works, and what side effects to look out for.

a few days .

Anyone who may be having a severe allergic reaction to the vaccine should call 911 or otherwise receive emergency medical attention. This reaction can lead to anaphylaxis and may involve difficulty breathing, closing of the throat, facial swelling, and hives. These reactions to the vaccine are very rare, and anaphylaxis affects 25 in every 1 million people who receive a COVID-19 vaccine.

Anaphylactic reactions to the vaccine tend to occur quickly. After having a dose of the vaccine, a person will be observed by a healthcare professional for about 15 minutes. This is to ensure that if an allergic reaction occurs, medical professionals are on hand and prepared with treatment.

Rare Reactions That Have Been Reported

As with all vaccines, there’s a very small chance that there will be a serious side effect. Most side effects are reported within the first 42 days following immunization. All side effect reports, including the rare reactions below, continue to be monitored closely by:

  • Health Canada
  • the Public Health Agency of Canada
  • provincial and territorial health authorities
  • the manufacturers

Health Canada is:

  • continuing to monitor emerging safety information about the vaccines in Canada and internationally
  • working closely with the manufacturers to ensure the labels on vaccines reflect relevant information, such as:
  • directions for use
  • warnings about side effects when used alone or when used with other products

Vaccines: What We Know About Long

If You Have a Skin Reaction to the Moderna COVID

“We don’t know the long-term side effects of Covid vaccines.” That’s a claim that’s still common to see shared online.

But a year is actually considered relatively “long term” when it comes to vaccine safety.

This week marks the anniversary of the first delivery of Covid-19 vaccines under the Covax scheme – as well as being more than 14 months since the first dose was given.

And scientists explain that’s enough time for all but the rarest side effects to have emerged.

Full List Of Ingredients

The Moderna COVID-19 vaccine contains the following ingredients:

Type of Ingredient

  • Nucleoside-modified mRNA encoding the viral spike glycoprotein of SARS-CoV-2


Provides instructions the body uses to build a harmless piece of a protein from the virus that causes COVID-19. This protein causes an immune response that helps protect the body from getting sick with COVID-19 in the future.

Type of Ingredient

  • SM-102: heptadecane-9-yl 8- hexyl) amino) octanoate


Work together to help the mRNA enter cells.

Type of Ingredient

Salt, sugar, acid stabilizers, and acid


  • Acetic acid


Work together to help keep the vaccine molecules stable while the vaccine is manufactured, frozen, shipped, and stored until it is ready to be given to a vaccine recipient.

What About More Serious Adverse Events

Theres a small increased risk of heart inflammation in people who have received an mRNA COVID vaccine , compared to unvaccinated people.

However, COVID infection is associated with a substantially higher risk of myocarditis, and other cardiac complications, compared to a COVID vaccination.

As of February 13, approximately 10 million third doses have been administered in Australia. Only six reports of likely myocarditis and 25 reports of likely pericarditis have been reported to the TGA for Pfizer, and four reports of likely myocarditis and eight reports of likely pericarditis for Moderna.

Data from Israel and US are also reassuring, finding lower rates of myocarditis and pericarditis following a third dose compared to a second dose of mRNA vaccines.

Not Everyone Responds The Same Way

It is also important to realise that not everyone experiences a disease in the same way.

Using COVID-19 infection as an example, we have seen some people hardly affected at all, some people experiencing mild symptoms, and others experiencing severe symptoms requiring hospital admission. There are many reasons why people respond differently to the same disease age, general health, gender and previous immunity may all contribute.7

In the same way, there will be a range of responses to a particular vaccine, with some people having few or no signs or symptoms, and others experiencing some or many.

General information on vaccines from the Department of Health explains what to expect after a vaccination, and the rare cases when medical attention is needed. It also explains when to report side effects. The TGA has been collecting and reviewing these reports of side effects for many years as part of its work ensuring the safe and effective use of medicines in Australia.

You can contact the NPS MedicineWise Adverse Medicine Events Line on 1300 134 237 if you have questions about vaccines or medicines, or if you experience unwanted signs or symptoms that you think may be linked to a medicine or vaccine and would like to report reactions to the TGA.

When Should I Be Concerned About Post

Pfizer and Moderna COVID-19 vaccines, side effects from second dose

“While different studies vary, fatigue is the most commonly reported side effect, with around 40-80% of people experiencing this,” Dr. Bhuyan explains, across Moderna, Pfizer, and Johnson & Johnsonâs vaccines. The way you feel that tiredness, of course, might be much different than how your roommate does. They might have been completely knocked out and had to miss a day of work, whereas you might just need a power nap.

It’s normal for people to have varying responses to the vaccine, Dr. Bhuyan tells Bustle. “Some people report being able to work after their vaccine with no issues others report mild fatigue that is slightly distracting and yet others report they have taken naps after their vaccine.” None of that means that the vaccine is working better or worse â it’s just different people’s bodies reacting in different ways. Think about that stomach bug you and your bestie both got on spring break that one time â you both caught the same thing, but you were up all night in the bathroom and they mostly just had a bad bellyache.

You might to get concerned if the post-vaccine fatigue wipes you out for more than 48 hours, Dr. Bhuyan says. If it reaches that point, check in with your doctor to make sure everything’s OK.

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.

How Do I Treat My Fatigue After Getting My Covid Shots

Unlike with post-vaccine soreness or headaches, there’s not really medicine you can take to help with fatigue, Dr. Bhuyan says. “With any symptoms, itâs best to listen to your body,” she explains. “For fatigue, if you need to rest, that is OK. Take it easy and donât put too much pressure on yourself. Continue to eat healthily and stay hydrated.”

You might also want to take some good old-fashioned days off from your usual activities. âAvoiding strenuous activity or drinking alcohol certainly are good practice,â Dr. Cherian says. âStaying hydrated can also help to minimize not only fatigue, but also other side effects as well.â In addition to downing plenty of H2O, if you’re able to call off work or push that deadline back so you can relax, go for it. You’ll spring back to normal soon â in the meantime, the best thing you can do for your body is rest.

Reports Of Very Rare Blood Clots

How Long Do COVID Vaccine Side Effects Last for Pfizer, Moderna ...

The Medicines and Healthcare products Regulatory Agency is carrying out a detailed review of reports of a very rare blood clotting problem affecting a small number of people who have had the Oxford/AstraZeneca vaccine.

The problem can also happen in people who have not been vaccinated and it’s not yet clear why it affects some people.

The current reported rate of this condition in the UK is around 15 cases per million first doses given.

The coronavirus vaccine can help stop you from getting seriously ill or dying from coronavirus. For people aged 40 or over and those with underlying health conditions, the benefits of being vaccinated outweigh any risk of clotting problems.

For people under 40, it’s currently advised that it’s preferable to have either the Pfizer/BioNTech or Moderna coronavirus vaccine.

If you have already had a first dose of the Oxford/AstraZeneca vaccine without suffering any serious side effects you should complete the course .

This includes people aged 18 to 39 years who are health and social care workers, unpaid carers and those who live with someone with a severely weakened immune system.

Ingredients That Are Not Used In Covid

The above table lists ALL ingredients in the Moderna COVID-19 vaccine. There are NO ingredients in this vaccine beyond what is listed in the table. The Moderna COVID-19 vaccine has

  • No preservatives like thimerosal or mercury or any other preservatives.
  • No antibiotics like sulfonamide or any other antibiotics.
  • No medicines or therapeutics like ivermectin or any other medications.
  • No tissues like aborted fetal cells, gelatin, or any materials from any animal.
  • No food proteins like eggs or egg products, gluten, peanuts, tree nuts, nut products, or any nut byproducts .
  • No metals like iron, nickel, cobalt, titanium, rare earth alloys, or any manufactured products like microelectronics, electrodes, carbon nanotubes or other nanostructures, or nanowire semiconductors.
  • No latex. The vial stoppers used to hold the vaccine also do not contain latex.

What Vaccine Is Being Offered

The Pfizer/BioNTech vaccine or Moderna vaccine is being offered as a booster dose to most people, which means they might receive a different vaccine to their first two jabs.

Some people may be offered a booster dose of the Oxford/AstraZeneca vaccine if they cannot have the Pfizer/BioNTech or Moderna vaccine.

Why Are Pfizer And Moderna Side Effects Worse After The Second Shot

The second dose of the Pfizer and Moderna vaccines is likely to cause more noticeable side effects. In both the Pfizer and Moderna vaccine clinical trials, more participants had symptoms like headache, fever, and body aches after the second dose. The effects tend to be more intense after the second shot because of the way your immune system responds to vaccines.

The Pfizer and Moderna COVID-19 vaccines are both reactogenic vaccines, which means they are likely to cause side effects. This doesnt mean, however, that everyone will have side effects, or that the vaccine doesnt work if it doesnt cause side effects. Heres a breakdown of how the vaccines produce an immune response and why the second dose typically results in stronger side effects.

If you have never been exposed to COVID-19 and get your first shot of the vaccine, the virus protein that the vaccine causes your cells to produce known as the spike protein is new to the body. This protein is harmless and will not infect you with the virus.

Your body recognizes the protein as an antigen, or something foreign, and starts reacting to it with inflammation at the injection site. This is why the first shot very commonly causes arm pain.

Even if you have had COVID-19, the Centers for Disease Control and Prevention still recommends getting fully vaccinated.

How Modernas Reactions Compare To Other Shots

Understanding COVID-19 vaccine side effects, why second dose could feel worse

Reactions to the Moderna vaccine are similar to those reported after the Pfizer vaccine, which is also an mRNA vaccine.

Recipients of both the Moderna and Pfizer mRNA vaccines commonly reported pain at the injection site and redness after the first dose, along with fatigue and joint pain after the second dose.

The reactions to the mRNA vaccines have not been terribly different, certainly not to a degree that an individual should choose one or the other on the basis of side effects, said Liu.

In clinical trials, the Johnson & Johnson shot was associated with milder side effects compared to the mRNA shots.

Since Moderna and Pfizer require two shots and most side effects were from the second shot, the J& J vaccine may have slightly fewer side effects, said Swaminathan.

At What Point Should You Call A Doctor

In most cases, discomfort from pain or fever is a normal sign that your body is building protection, the CDC states. Still, the agency recommends you contact your doctor or healthcare provider if:

  • The redness or tenderness where you got the shot gets worse after 24 hours
  • Your side effects are worrying you or do not seem to be going away after a few days

Anyone who believes they are experiencing a severe allergic reaction after leaving the vaccination site should also seek immediate medical care by calling 911, the CDC recommends.

Throughout The Rest Of Your Body:

  • Tiredness
  • Fever
  • Nausea

Anyone who has had a severe allergic reaction after getting a mRNA COVID-19 vaccine , should not get another dose of either of the mRNA COVID-19 vaccines. Anyone who has had a severe allergic reaction after receiving Johnson & Johnsons Janssen COVID-19 vaccine, should not receive another dose of that vaccine.

Reactions Are More Intense After Second Dose And Developing Covid

The Moderna shot is a messenger RNA vaccine that teaches our cells to make a piece of SARS-CoV-2 protein and mount an immune response against it.

That way, if a person were to be exposed to the coronavirus, their body would already know how to fight it and prevent severe disease.

The first dose is considered the prime and trains your body to recognize the virus, according to Swaminathan.

Since that is the first exposure, reactions tend to be mild, Swaminathan said.

The second dose, the booster, further cements the immune response.

Since the patients have already seen the vaccine from the first shot, the second booster is an exaggerated response to the same, Swaminathan said.

Research also suggests reactions are more intense in people who previously had COVID-19 since they likely have some level of preexisting immunity.

Why Do We Need To Report Adverse Events


Any vaccine, including the COVID-19 vaccines, is only approved when it meets high quality standards and has been shown in clinical studies of sufficient size and rigour to be safe and effective. NPS MedicineWise has more information about clinical trials, why they are important and their role in the approval of medicines and vaccines for use in Australia.

Clinical trials are a very important part of understanding the effects and the safety of a medicine or a vaccine, but they cannot detect all possible harms:

They will not be able to detect adverse events that take longer to develop than the length of the trial.

A very rare adverse event may not be detected if it is so rare that it didnt happen to anyone in the trial.

Also, some population groups may have been excluded from taking part in the clinical trial, and so any adverse effects that only occur in these groups would not be known from the clinical trials.
