How Long Can Covid Vaccine Side Effects Linger

Reactions Side Effects And Long

COVID-19 vaccine side effects

Reactions to a vaccine usually occur shortly after the vaccination and can last for several days. In the case of the COVID-19 vaccines, these can involve pain or tenderness at the injection site in other words, a sore arm or headaches. These symptoms show that the body’s immune system is dealing with the vaccine.

What can be called “side effects” are stronger reactions to a vaccine. They are “an undesirable reaction of the body to the vaccine that occurs in addition to the completely normal vaccination reaction,” said Christine Falk, president of the German Society for Immunology and professor at the Institute for Transplantation Immunology in Hannover, in an interview with DW.

They are more serious than usual reactions and, in the most extreme cases, can lead to damage that has a longer-term impact on health. Very rare side effects such as cerebral venous sinus thrombosis or heart muscle inflammation have already been reported with COVID-19 vaccines.

You Should Wait To Get The Second Shot If You Catch Covid In

The CDC says you should not get the vaccine if you are currently infected with COVID. So if you do get the coronavirus in-between the first and second dose of Pfizer or Moderna, you should postpone your second shot. “Vaccination of people with known current SARS-CoV-2 infection should be deferred until the person has recovered from the acute illness and they have met criteria to discontinue isolation,” the CDC says.

If you do need to delay your second dose, the agency says it can still be administered up to six weeks after the first dose. However, if you are just experiencing side effects after the first shot and not the virus, you should still get your second shot on time “unless a vaccination provider or your doctor tells you not to get it,” the CDC says.

Possible Side Effects After Booster Shot

Reactions reported after getting a Pfizer-BioNTech booster shot were like those after the initial two doses . Overall, most side effects were mild to moderate. However, as with the primary series, serious side effects are rare, but may occur.

Should People With Underlying Health Conditions Get The Vaccine

If you have underlying health conditions, you can get the vaccine. In fact, this is particularly important because some health conditions can put you at a higher risk of serious COVID-19 complications.

Currently, the only exception to this is if youve had a serious or immediate allergic reaction to one or more ingredients in the vaccine. In this case, you should avoid getting the vaccine.

If you have an underlying health condition and have questions about receiving the vaccine, be sure to speak with your healthcare provider.

Its pretty normal to feel mild symptoms like those described above after getting a vaccine. Although it can be unpleasant, its actually a good sign. It means that your body is in the process of generating an immune response.

While these side effects can be unpleasant, theyre typically mild or moderate and go away after a few days.

Side effects that are felt throughout your body, such as fatigue and fever, are more common after getting the second dose.

Does Johns Hopkins Medicine Recommend That I Get A Covid

Yes, we recommend that everyone who is eligible get vaccinated with one of the three currently authorized COVID-19 vaccines. Johns Hopkins Medicine is administering all three vaccines: Pfizer-BioNTech, Moderna and Johnson & Johnson. We view all three as highly effective in preventing serious disease, hospitalization and death from COVID-19 , and we believe that their benefits outweigh their risks.

Which Covid Vaccine Has The Least Side Effects

According to doctor Khan, this data is not available, so we dont know this yet.

However, doctor Liakas shares that it depends on a range of variables.

With the Pfizer vaccine, adverse reactions were reported more by younger people, rather than those over the age of 55 years, he explains.

On the other hand, the adverse reactions from the Oxford/AstraZeneca vaccine were generally seen by younger people, he shares. Plus, the strongest association between thrombosis and the Oxford/AstraZeneca vaccine was found between younger people and especially young women.

Do note: as a result, the official advice for women under the age of 40 is still to opt for one of the other vaccines.

Robust And Reassuring Data

“The safety monitoring of the mRNA COVID-19 vaccines stands out as the most comprehensive of any vaccine in U.S. history. The use of these complementary monitoring systems has provided robust and reassuring data,” Matthew S. Krantz, MD, and Elizabeth J. Phillips, MD, with the Vanderbilt University School of Medicine in Nashville, said.

Krantz and Phillips point out in a separate commentary that the v-safe reports of reactions are consistent with those reported from clinical trials and a real-life study in the United Kingdom.

“lthough approximately one in 1000 individuals vaccinated may have an adverse effect, most of these are nonserious,â Phillips said in a press release.

There were no unusual patterns, she said.

Which Vaccine Will I Get

Why does your arm hurt after the COVID-19 vaccine?

You cannot usually choose which vaccine you have. When you book, youll only be offered appointments for vaccines that are suitable for you.

Most people can have any of the COVID-19 vaccines, but some people are only offered certain vaccines.

For example:

  • if youre pregnant or under 40 youll usually be offered appointments for the Pfizer/BioNTech or Moderna vaccines
  • if youre under 18, youll only be offered the Pfizer/BioNTech vaccine

You should have the same vaccine for both doses, unless you had serious side effects after your 1st dose.

Vaccine Side Effects Show Up Within Weeks If At All

That is not to say that there have never been safety issues with vaccines. But in each instance, these have appeared soon after widespread use of the vaccine began. “The side effects that we see occur early on and that’s it,” Goepfert said. In virtually all cases, vaccine side effects are seen within the first two months after rollout.

The only vaccine program that might compare with the scale and speed of the COVID rollout is the original oral polio vaccine in the 1950s, Goepfert says. When this vaccine was first introduced in the United States in 1955, it used a weakened form of the polio virus that in very rare cases about 1 in 2.4 million recipients became activated and caused paralysis. Cases of vaccine-induced paralysis occurred between one and four weeks after vaccination. None of the COVID vaccines uses a weakened form of the SARS-CoV-2 virus all train the body to recognize a piece of the virus known as the spike protein and generate antibodies that can attack the virus in case of a real infection.

In 1976, a vaccine against swine flu that was widely distributed in the United States was identified in rare cases as a cause of Guillain-Barré Syndrome, in which the immune system attacks the nerves. Almost all of these cases occurred in the eight weeks after a person received the vaccine. But the flu itself also can cause Guillain-Barré Syndrome in fact, the syndrome occurs 17 times more frequently after natural flu infection than after vaccination.

What About The Thrombosis Cases Linked To Astrazeneca

This is a rare side effect that was discovered by health officials only after the AstraZeneca vaccine was rolled out, Förster confirmed. There were some severe cases with blood clots in different or unusual locations .

Thrombosis, which is a rare side effect of the COVID-19 vaccine, can be treated effectively

“The clinical trials can show the more common reactions to the vaccine, but unfortunately not the rare ones because of the relatively small number of cases,” immunologist Falk explained. That’s why this side effect didn’t come to light until after the vaccine was approved, she said.

According to Australian health authorities, thrombosis occurs only in a maximum of four to six people out of 1 million who are vaccinated with AstraZeneca.

According to Germany’s Federal Center for Health Education, the majority of thrombosis cases usually occurred two to three weeks after vaccination, predominantly in people under 60 years of age. That’s why, as of April 1, Germany now only recommends vaccinating people 60 and older with AstraZeneca. If the side effect is detected early enough, it can be treated.

Vaccine Rollout Takes Shaky First Steps

Vaccine rollout for children under 5 wont look like the ones for older kids and adults, according to Dr. Ashish Jha, the White House COVID response coordinator.

Instead of mass vaccination sites, other more familiar locations like doctors offices, health clinics, pharmacies, and childrens hospitals will administer most of the jabs because thats what parents prefer, Jha wrote on Twitter.

We want to build a response and an availability system that is responsive to parents needs and desires, he said, adding that well see more and more vaccines and appointments open up as sites receive their first orders, which were shipped last week.

But eager caregivers are already running into issues, an early sign that they say reveals poor planning on the governments end.

Lauren Thompson told us she called her local health department in Virginia last week to find out whether her county will have vaccines for kids under 5 as soon as they become available. She was told they were waiting to see if there was a demand for the shots before ordering any. Thompsons pediatrician then told her their office was interested in the vaccine but wont have it when its first available.

Im grateful that I have access to PTO, as well as a car to be able to make the trip there, she said. Why was there no solid distribution plan?? Why is everything so inequitable?

Vaccination Can Prevent Long Covid


COVID-19 vaccines are safe and effective, even though some patients may experience breakthrough infections, said Dr. Sanghavi. What is reassuring is that patients who were vaccinated, in those rare instances where they got a breakthrough infection those patients are 50% less likely to develop long COVID or post COVID syndrome.

The vaccines are effective. But in those rare instances where you do get an infection despite vaccination, this protects you from having post-COVID syndrometheres a double insurance.

How Long Do Covid Vaccine Side Effects Last

The most common side effects of all the coronavirus vaccines are similar and usually short-lived, shares doctor Riz Khan, GP and doctor of nutritional medicine at 24.

They typically dont last longer than a week. Symptoms to have on your radar include:

  • A sore, red or itchy arm
  • Swelling
  • Nausea
  • A temperature.

These are normal and a sign that your immune system is working to develop a response to the vaccine and subsequently create antibodies to protect you from Covid-19, he explains.

In short, you might experience flu-like symptoms, shares doctor Liakas if you think about it, you are getting injected with a live virus to enable your body to fight it off. He goes on: With all three COVID-19 vaccines, around 10% of those vaccinated have generally said complained of flu-like symptoms, like the ones outlined above, he shares.

This is the same with most vaccines, he reports. Wondering if you can exercise after your Covid vaccine? Read our expert-led guide.

Although the above side effects are common to all three vaccines, there are some more associated with a specific vaccine.

What Would A Doctors Advice Be To Anyone Worried About More Severe Side Effects

Its important to stress here: all COVID-19 vaccines can prevent serious illness or the risk of dying from coronavirus, warns doctor Liakas.

Even with the very small number of reported risks of blood clotting problems with the Oxford/AstraZeneca vaccine, the benefits of being vaccinated outweigh any risk, especially for people aged 40 and over who also have underlying health conditions, he shares.

Are Side Effects More Likely After The First Or Second Dose

With the two-shot vaccines, people are more likely to report side effects after their second dose, experts have said.

According to the CDC, side effects after your second shot “may be more intense than the ones you experienced after your first shot.”

“These side effects are normal signs that your body is building protection and should go away within a few days,” the CDC states.

In trials of both the Moderna and Pfizer vaccines, more people experienced side effects after the second dose.

But that doesn’t mean that you shouldn’t get your second shot if you get side effects after your first, experts say.

The CDC also noted that both shots are needed.

“The Pfizer-BioNTech COVID-19 Vaccine and Moderna COVID-19 Vaccine both need 2 shots in order to get the most protection,” the CDC states. “You should get the second shot even if you have side effects after the first shot, unless a vaccination provider or your doctor tells you not to get it.”

Experts Urge Vaccination As Coronavirus Evolves

7. What are the long term side effects of the COVID-19 vaccine?

Since the pandemic began, more than 2.5 million children under 5 have contracted COVID, the latest CDC data shows.

COVID has become the fourth leading cause of death among babies and the fifth for children between ages 1 and 4 in the US. More than 200 children in this age group have died from the disease, according to death certificates as of May 11.

COVID has also caused more US deaths per year in this age group than other infectious diseases did before vaccines became available for them, including those caused by meningococcal bacteria and viruses like hepatitis A, varicella, rubella, and rotavirus.

Infections in this age group soared in January when the more contagious omicron variant took over. Its the next variant, however, that doctors are worried about. Thats why they say children under 5 should still get vaccinated even if theyve already had COVID: it may offer protection against future variants.

Getting vaccinated after having COVID-19 will give your child the best defense against new variants of the virus, Dr. Diego Hijano, a pediatric infectious disease specialist at St. Jude Childrens Research Hospital, wrote in an email. If a child or anyone gets COVID-19, there is no way to predict if it is going to be a mild or a severe infection, and options to treat COVID-19 in young children are limited.

Not to mention, vaccination can prevent infection and therefore the risks of developing long COVID.

Pfizer Vaccine Side Effects

According to doctor Liakas, the most prevalent side effects with the Pfizer vaccine are the above flu-like symptom and an extended feeling of sickness or swollen lymph nodes.

However, do note here, there are much rarer at less than 1%.

Another side affect which is even more rare is possibility of developing temporary one-sided facial drooping. But this is in less than 0.1% of the vaccinated population, explains doctor Liakas.

    Magdalena Cadet, MD, a New York City-based rheumatologist, told POPSUGAR that symptoms typically last between 24 to 48 hours, but some people have reported feeling the side effects for up to 72 hours. Dr. Cadet added that discomfort in the arm may briefly intensify 24 hours after getting the shot, and she recommends resting your arm and avoiding any heavy lifting or activity. Similarly, Dr. Singh said that most mild or moderate symptoms shouldn’t last for longer than a couple days.

    Mrna Allergic Reactions And Future Doses

    Its possible for most people who experienced an allergic reaction to a COVID-19 vaccine to safely receive future doses of that same vaccine. This includes with an mRNA vaccine.

    The National Advisory Committee on Immunization has recommendations for people who experienced a severe immediate allergic reaction after a first dose of an mRNA COVID-19 vaccine. People with a history of a severe immediate allergic reaction after a first dose of an mRNA COVID-19 vaccine should:

    • consult with an allergist or another appropriate health care provider before receiving future doses of an mRNA COVID-19 vaccine
    • receive future doses of an mRNA COVID-19 vaccine in a controlled setting with someone who is experienced in managing anaphylaxis
    • be observed for at least 30 minutes after vaccination
    • the normal observation period for people who havent experienced a severe immediate allergic reaction after vaccination is 15 minutes

    If you know youre allergic to a component of an mRNA COVID-19 vaccine, consult with an allergist or your health care provider. It may still be possible for you to receive these vaccines.
