Many people with these adverse effects recover with prompt treatment.\nGetting the\nCOVID-19 vaccine\nis important for preventing serious illness and death from the coronavirus. As with any vaccine, the COVID-19 vaccine can have side effects. Many of these are mild and go away in a few days.\nIn rare cases, more serious adverse effects that cause shortness of breath can occur. Keep reading to learn more about the causes of shortness of breath after COVID-19 vaccination and how they’re diagnosed and treated.\nIn rare instances, a few things may cause\nshortness of breath\nafter getting the COVID-19 vaccine. These include:\nmyocarditis\npericarditis\nanaphylaxis\nMyocarditis and pericarditis\nMyocarditis\nand\npericarditis\nare both types of heart inflammation. In addition to shortness of breath, a person with myocarditis or pericarditis can experience symptoms like:\nchest pain\nracing or pounding heart\nweakness\nfatigue\nThe\nCDC\nnotes that myocarditis and pericarditis are rare adverse effects of the COVID-19 vaccine that mostly happen in adolescent and young adult males. These rare effects typically occur:\nafter getting an\nmRNA COVID-19 vaccine\n, like the Pfizer-BioNTech or Moderna vaccine\nwithin a week of getting a vaccine dose\nafter getting the second dose in the primary vaccine series\nA\n2022 study\nfound that the rates of myocarditis in adolescent and young adult males after the second vaccine dose were:\n70.7 cases per 1 million doses of the Pfizer-BioNTech vaccine in males ages 12 to 15\n105.9 cases per 1 million doses of the Pfizer-BioNTech vaccine in males ages 16 to 17\n52.4 cases and 56.3 cases per 1 million doses of the Pfizer-BioNTech and the Moderna vaccine, respectively, in males ages 18 to 24\nSeveral\nstudies have\nfound\nthat the risk of myocarditis and pericarditis is actually\nhigher\nafter getting\nCOVID-19\nthan it is after getting vaccinated.\nAnaphylaxis\nAnaphylaxis\nis a severe, life threatening allergic reaction. It may cause symptoms like:\nbreathing problems, which can include:\nshortness of breath\nrapid, shallow breathing\nwheezing\ndifficulty breathing\nswelling of the\ntongue\nor throat\ndizziness\n,\nlightheadedness\n, or\nfainting\nrash\nclammy skin\nrapid heart rate\nnausea or\nvomiting\nabdominal pain\ndiarrhea\nanxiety\nor a\nfeeling of impending doom\nIt’s possible for anaphylaxis to occur after any type of COVID-19 vaccine. However, it’s still very rare. The CDC estimates it occurs at a rate of\n5 cases per 1 million vaccine doses\n.\nMost instances of myocarditis or pericarditis are\nmild or moderate\n. The\nCDC\nnotes that most people with these adverse effects who receive treatment respond well and feel better quickly.\nA\n2023 study\nalso found that the outlook for people with myocarditis after COVID-19 vaccination was better when compared with people with conventional myocarditis or COVID-19-associated myocarditis.\nPeople who have had myocarditis or pericarditis after getting sick with COVID-19\nshould not\nreceive another dose of that particular vaccine unless cleared by their doctor.\nAnaphylaxis typically resolves after treatment.

If you have symptoms of anaphylaxis in the minutes or hours after getting a COVID-19 vaccine, call 911 or local emergency services.\n### Myocarditis and pericarditis\nA doctor can diagnose and treat myocarditis or pericarditis by:\n\n- performing a physical exam and taking your medical history\n- ordering blood tests, like tests for:\n  - [troponin](https:\/\/www.healthline.com\/health\/troponin-levels)\n  - [C-reactive protein](https:\/\/www.healthline.com\/health\/c-reactive-protein)\n  - [erythrocyte sedimentation rate](https:\/\/www.healthline.com\/health\/esr)\n- doing an [electrocardiogram (EKG)](https:\/\/www.healthline.com\/health\/electrocardiogram)\n- using imaging, such as a:\n  - [chest X-ray](https:\/\/www.healthline.com\/health\/chest-x-ray)\n  - [echocardiogram](https:\/\/www.healthline.com\/health\/echocardiogram)\n  - [MRI](https:\/\/www.healthline.com\/health\/heart-mri)\n\nA [cardiologist](https:\/\/www.medicalnewstoday.com\/articles\/248935) typically treats these conditions. Treatment may involve medications geared toward reducing inflammation, such as:\n\n- [nonsteroidal anti-inflammatory drugs (NSAIDs)](https:\/\/www.healthline.com\/health\/side-effects-from-nsaids)\n- [steroids](https:\/\/www.healthline.com\/health\/corticosteroids-what-are-they)\n- [intravenous immunoglobulin (IVIG)](https:\/\/www.healthline.com\/health\/ivig-infusion)\n\nYou’ll also need to get plenty of rest as you recover.\n\n### Anaphylaxis\nAnaphylaxis typically comes on suddenly [15 to 30 minutes](https:\/\/www.cdc.gov\/vaccines\/covid-19\/clinical-considerations\/managing-anaphylaxis.html) after vaccination. However, sometimes it may take hours to develop. Diagnosis is typically made based on the appearance of symptoms after a specific trigger.\n\nTreatment involves an [epinephrine](https:\/\/www.healthline.com\/health\/epinephrine-vs-norepinephrine) injection, typically with an [EpiPen](https:\/\/www.healthline.com\/health\/anaphylaxis\/how-to-use-epipen), as well as supportive care in a hospital.\n\n## [What’s the outlook for people with shortness of breath after the COVID-19 vaccine?]()\nMost instances of myocarditis or pericarditis are [mild or moderate](https:\/\/www.nejm.org\/doi\/full\/10.1056\/NEJMoa2110737).

Meta Canonical	null
Boilerpipe Text	Shortness of breath isn’t common after the COVID-19 vaccine. However, it may happen due to rare adverse effects, like myocarditis, pericarditis, or anaphylaxis. Many people with these adverse effects recover with prompt treatment. Getting the COVID-19 vaccine is important for preventing serious illness and death from the coronavirus. As with any vaccine, the COVID-19 vaccine can have side effects. Many of these are mild and go away in a few days. In rare cases, more serious adverse effects that cause shortness of breath can occur. Keep reading to learn more about the causes of shortness of breath after COVID-19 vaccination and how they’re diagnosed and treated. In rare instances, a few things may cause shortness of breath after getting the COVID-19 vaccine. These include: myocarditis pericarditis anaphylaxis Myocarditis and pericarditis Myocarditis and pericarditis are both types of heart inflammation. In addition to shortness of breath, a person with myocarditis or pericarditis can experience symptoms like: chest pain racing or pounding heart weakness fatigue The CDC notes that myocarditis and pericarditis are rare adverse effects of the COVID-19 vaccine that mostly happen in adolescent and young adult males. These rare effects typically occur: after getting an mRNA COVID-19 vaccine , like the Pfizer-BioNTech or Moderna vaccine within a week of getting a vaccine dose after getting the second dose in the primary vaccine series A 2022 study found that the rates of myocarditis in adolescent and young adult males after the second vaccine dose were: 70.7 cases per 1 million doses of the Pfizer-BioNTech vaccine in males ages 12 to 15 105.9 cases per 1 million doses of the Pfizer-BioNTech vaccine in males ages 16 to 17 52.4 cases and 56.3 cases per 1 million doses of the Pfizer-BioNTech and the Moderna vaccine, respectively, in males ages 18 to 24 Several studies have found that the risk of myocarditis and pericarditis is actually higher after getting COVID-19 than it is after getting vaccinated. Anaphylaxis Anaphylaxis is a severe, life threatening allergic reaction. It may cause symptoms like: breathing problems, which can include: shortness of breath rapid, shallow breathing wheezing difficulty breathing swelling of the tongue or throat dizziness , lightheadedness , or fainting rash clammy skin rapid heart rate nausea or vomiting abdominal pain diarrhea anxiety or a feeling of impending doom It’s possible for anaphylaxis to occur after any type of COVID-19 vaccine. However, it’s still very rare. The CDC estimates it occurs at a rate of 5 cases per 1 million vaccine doses . Most instances of myocarditis or pericarditis are mild or moderate . The CDC notes that most people with these adverse effects who receive treatment respond well and feel better quickly. A 2023 study also found that the outlook for people with myocarditis after COVID-19 vaccination was better when compared with people with conventional myocarditis or COVID-19-associated myocarditis. People who have had myocarditis or pericarditis after getting sick with COVID-19 should not receive another dose of that particular vaccine unless cleared by their doctor. Anaphylaxis typically resolves after treatment. If you experienced anaphylaxis after a dose of a COVID-19 vaccine, you should not receive another dose of that type of vaccine.

However, it may happen due to rare adverse effects, like myocarditis, pericarditis, or anaphylaxis. Many people with these adverse effects recover with prompt treatment. Getting the [COVID-19 vaccine](https://www.healthline.com/health-news/heres-exactly-where-were-at-with-vaccines-and-treatments-for-covid-19) is important for preventing serious illness and death from the coronavirus. As with any vaccine, the COVID-19 vaccine can have side effects. Many of these are mild and go away in a few days. In rare cases, more serious adverse effects that cause shortness of breath can occur. Keep reading to learn more about the causes of shortness of breath after COVID-19 vaccination and how they’re diagnosed and treated. ### Common side effects of the COVID-19 vaccine According to the [Centers for Disease Control and Prevention (CDC)](https://www.cdc.gov/coronavirus/2019-ncov/vaccines/expect/after.html), the common side effects of the COVID-19 vaccine in adults include: - pain, redness, or swelling at the injection site - [fatigue](https://www.healthline.com/health/fatigue) - [fever](https://www.healthline.com/health/fever-symptoms) - [chills](https://www.healthline.com/health/chills) - [muscle aches](https://www.healthline.com/health/muscle-aches) - [headache](https://www.healthline.com/health/headache) - [nausea](https://www.healthline.com/health/nausea) ## [What might cause shortness of breath after the COVID-19 vaccine?]() In rare instances, a few things may cause [shortness of breath](https://www.healthline.com/health/what-does-shortness-of-breath-feel-like) after getting the COVID-19 vaccine. These include: - myocarditis - pericarditis - anaphylaxis ### Myocarditis and pericarditis [Myocarditis](https://www.healthline.com/health/heart-disease/myocarditis) and [pericarditis](https://www.healthline.com/health/pericarditis) are both types of heart inflammation. In addition to shortness of breath, a person with myocarditis or pericarditis can experience symptoms like: - [chest pain](https://www.healthline.com/health/causes-of-chest-pain) - [racing or pounding heart](https://www.healthline.com/health/dangerous-heart-rate) - [weakness](https://www.healthline.com/health/weakness) - fatigue The [CDC](https://www.cdc.gov/coronavirus/2019-ncov/vaccines/safety/myocarditis.html) notes that myocarditis and pericarditis are rare adverse effects of the COVID-19 vaccine that mostly happen in adolescent and young adult males. These rare effects typically occur: - after getting an [mRNA COVID-19 vaccine](https://www.healthline.com/health/how-does-mrna-vaccine-work), like the Pfizer-BioNTech or Moderna vaccine - within a week of getting a vaccine dose - after getting the second dose in the primary vaccine series A [2022 study](https://jamanetwork.com/journals/jama/fullarticle/2788346) found that the rates of myocarditis in adolescent and young adult males after the second vaccine dose were: - 70\.7 cases per 1 million doses of the Pfizer-BioNTech vaccine in males ages 12 to 15 - 105\.9 cases per 1 million doses of the Pfizer-BioNTech vaccine in males ages 16 to 17 - 52\.4 cases and 56.3 cases per 1 million doses of the Pfizer-BioNTech and the Moderna vaccine, respectively, in males ages 18 to 24 [Several](https://www.nature.com/articles/s41591-021-01630-0) studies have [found](https://www.ahajournals.org/doi/full/10.1161/CIRCULATIONAHA.122.059970) that the risk of myocarditis and pericarditis is actually [higher](https://www.cdc.gov/mmwr/volumes/71/wr/mm7114e1.htm) after getting [COVID-19](https://www.healthline.com/health/coronavirus-covid-19) than it is after getting vaccinated. ### Anaphylaxis [Anaphylaxis](https://www.healthline.com/health/anaphylaxis) is a severe, life threatening allergic reaction. It may cause symptoms like: - breathing problems, which can include: - shortness of breath - [rapid, shallow breathing](https://www.healthline.com/health/rapid-shallow-breathing) - [wheezing](https://www.healthline.com/health/wheezing) - [difficulty breathing](https://www.healthline.com/health/breathing-difficulties) - swelling of the [tongue](https://www.healthline.com/health/tongue-problems) or throat - [dizziness](https://www.healthline.com/health/dizziness), [lightheadedness](https://www.healthline.com/health/lightheadedness), or [fainting](https://www.healthline.com/health/fainting) - [rash](https://www.healthline.com/health/rashes) - [clammy skin](https://www.healthline.com/health/skin-clammy) - rapid heart rate - nausea or [vomiting](https://www.healthline.com/health/vomiting-causes-treatment) - [abdominal pain](https://www.healthline.com/health/abdominal-pain) - [diarrhea](https://www.healthline.com/health/diarrhea) - [anxiety](https://www.healthline.com/health/anxiety-symptoms) or a [feeling of impending doom](https://www.healthline.com/health/feeling-of-impending-doom) It’s possible for anaphylaxis to occur after any type of COVID-19 vaccine. However, it’s still very rare. The CDC estimates it occurs at a rate of [5 cases per 1 million vaccine doses](https://www.cdc.gov/coronavirus/2019-ncov/vaccines/safety/adverse-events.html). ### Other causes of shortness of breath after the COVID-19 vaccine There are also some other rarer causes of shortness of breath that have been associated with mRNA COVID-19 vaccines: - Interstitial lung disease (ILD): [ILD](https://www.healthline.com/health/interstitial-lung-disease) refers to conditions that lead to scarring of the lungs. [Reports](https://thorax.bmj.com/content/77/1/9) of ILD after the COVID-19 vaccine are [limited](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8942814/) to several case [reports](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8450284/) . - Pneumonitis: [Pneumonitis](https://www.healthline.com/health/pneumonitis) is a general term for lung inflammation. A [couple](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9548798/) of case [reports](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8810239/) have described pneumonitis after the COVID-19 vaccine. Case reports are detailed descriptions of disease in a single person. As such, compared with the number of vaccine doses given worldwide, these adverse effects are exceedingly rare. ## [How is shortness of breath after a COVID-19 vaccine diagnosed and treated?]() ### What to do if you have serious side effects after the COVID-19 vaccine Seek medical care if you develop symptoms of myocarditis or pericarditis in the days after getting the COVID-19 vaccine. These conditions can become serious if they’re not treated. Anaphylaxis is a medical emergency. If you have symptoms of anaphylaxis in the minutes or hours after getting a COVID-19 vaccine, call 911 or local emergency services. ### Myocarditis and pericarditis A doctor can diagnose and treat myocarditis or pericarditis by: - performing a physical exam and taking your medical history - ordering blood tests, like tests for: - [troponin](https://www.healthline.com/health/troponin-levels) - [C-reactive protein](https://www.healthline.com/health/c-reactive-protein) - [erythrocyte sedimentation rate](https://www.healthline.com/health/esr) - doing an [electrocardiogram (EKG)](https://www.healthline.com/health/electrocardiogram) - using imaging, such as a: - [chest X-ray](https://www.healthline.com/health/chest-x-ray) - [echocardiogram](https://www.healthline.com/health/echocardiogram) - [MRI](https://www.healthline.com/health/heart-mri) A [cardiologist](https://www.medicalnewstoday.com/articles/248935) typically treats these conditions. Treatment may involve medications geared toward reducing inflammation, such as: - [nonsteroidal anti-inflammatory drugs (NSAIDs)](https://www.healthline.com/health/side-effects-from-nsaids) - [steroids](https://www.healthline.com/health/corticosteroids-what-are-they) - [intravenous immunoglobulin (IVIG)](https://www.healthline.com/health/ivig-infusion) You’ll also need to get plenty of rest as you recover. ### Anaphylaxis Anaphylaxis typically comes on suddenly [15 to 30 minutes](https://www.cdc.gov/vaccines/covid-19/clinical-considerations/managing-anaphylaxis.html) after vaccination. However, sometimes it may take hours to develop. Diagnosis is typically made based on the appearance of symptoms after a specific trigger. Treatment involves an [epinephrine](https://www.healthline.com/health/epinephrine-vs-norepinephrine) injection, typically with an [EpiPen](https://www.healthline.com/health/anaphylaxis/how-to-use-epipen), as well as supportive care in a hospital. ## [What’s the outlook for people with shortness of breath after the COVID-19 vaccine?]() Most instances of myocarditis or pericarditis are [mild or moderate](https://www.nejm.org/doi/full/10.1056/NEJMoa2110737). The [CDC](https://www.cdc.gov/coronavirus/2019-ncov/vaccines/safety/myocarditis.html) notes that most people with these adverse effects who receive treatment respond well and feel better quickly. A [2023 study](https://bmjmedicine.bmj.com/content/2/1/e000373) also found that the outlook for people with myocarditis after COVID-19 vaccination was better when compared with people with conventional myocarditis or COVID-19-associated myocarditis. People who have had myocarditis or pericarditis after getting sick with COVID-19 [should not](https://www.cdc.gov/vaccines/covid-19/clinical-considerations/interim-considerations-us.html#myocarditis-pericarditis) receive another dose of that particular vaccine unless cleared by their doctor. Anaphylaxis typically resolves after treatment. If you experienced anaphylaxis after a dose of a COVID-19 vaccine, you [should not](https://www.cdc.gov/coronavirus/2019-ncov/vaccines/safety/allergic-reaction.html) receive another dose of that type of vaccine. »MORE:[Get an online treatment plan for COVID-19 in as little as 15 minutes with Optum Now Online Care.](https://now.optum.com/online-care/app/cp_12q_449a_covid19coronavirus?utm_source=healthline&utm_medium=organic-onlinecare-on&utm_content=linkto-oc-on-covid-19&utm_campaign=hl-article-oc-on-backlink) Optum Now is operated by RVO Health.

This can be caused by rare adverse effects like myocarditis, pericarditis, or anaphylaxis. With treatment, many people with shortness of breath after the COVID-19 vaccine recover without lingering problems. Myocarditis and pericarditis can become serious, while anaphylaxis is a medical emergency. Always seek prompt medical care if you have concerning symptoms like shortness of breath, chest pain, or rash after getting the COVID-19 vaccine. ### How we reviewed this article: Sources History Healthline has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical journals and associations.
