Are long-term side effects possible with the COVID-19 vaccine?
Benefits of Vaccination Outweigh the Risks Serious side effects that could cause a long-term health problem are extremely unusual following any vaccination, including COVID-19 vaccination.
Is the COVID-19 vaccine safe?
COVID-19 vaccines are safe and effective. You may have side effects after vaccination, but these are normal.
Are COVID-19 vaccines safe even though the vaccines were developed rapidly?
See full answerAlthough COVID-19 vaccines were developed quickly, research and development on vaccines like these have been underway for decades. All vaccine development steps were taken to ensure COVID-19 vaccine safety and effectiveness, including:
- Clinical Trials – All vaccines in the United States must go through three phases of clinical trials to ensure they are safe and effective. The phases overlapped to speed up the process, but all phases were completed.
- Authorization or Approval – Before vaccines are available to people, the U.S. Food and Drug Administration (FDA) reviews data from clinical trials. FDA has determined three COVID-19 vaccines meet FDA’s standards and has granted those vaccines Emergency Use Authorizations (EUAs)external icon or full FDA approval.
Do COVID-19 mRNA vaccines have long-term effects?
The Pfizer and Moderna vaccines were created using messenger RNA (or mRNA) technology, which has been used for about 10 years in cancer treatment, with no long-term effects detected. And even before that, scientists had been working with mRNA technology for years. 3. mRNA technology does not alter your DNA.
What are some of the long-term side effects of COVID-19?
The effects of COVID-19 can persist long after the initial symptoms of the illness are gone. These effects, called post-acute sequelae of COVID-19 (or PASC), can include brain fog, fatigue, headaches, dizziness, and shortness of breath.
What are some of the side effects of the Pfizer COVID-19 vaccine?
Adverse Reactions in Clinical Trials Adverse reactions following administration of the Pfizer-BioNTech COVID-19 Vaccine that have been reported in clinical trials include injection site pain, fatigue, headache, muscle pain, chills, joint pain, fever, injection site swelling, injection site redness, nausea, malaise.
What exactly does the COVID-19 vaccine do to the body?
COVID-19 vaccines help our bodies develop immunity to the virus that causes COVID-19 without us having to get the illness.
How was the COVID-19 vaccine developed so quickly?
Scientists began work on the COVID-19 vaccine in January 2020. Dedicated vaccine funding helped move vaccine candidates through the pre-clinical/clinical assessments and trials both quickly and thoughtfully. This has enabled researchers to advance into phase 3 clinical trials (testing the vaccine on large groups of people to evaluate safety and effectiveness) in six months instead of the typical two years. The vaccine was mass produced before the clinical studies were complete to save time.
Is it recommended to get the new COVID-19 Omicron booster?
Yes. Even if youve been infected with COVID in the past year and/or received the prior series of primary vaccines and boosters, you should get a bivalent Omicron shot. Doing so will give you broader immunity against COVID and also help limit the emergence of other variants.
Do mRNA COVID-19 vaccines cause heart inflammation?
These cases typically occur in male adolescents and young adults after the second dose, and within a week of vaccination. It is important to seek medical care if symptomatic (chest pain, shortness of breath, having a fast beating, fluttering, or pounding heart).
Can COVID-19 cause problems years later?
In some people, post- COVID-19 syndrome lasts months or years or causes disability. Research suggests that between one month and one year after having COVID-19 , 1 in 5 people ages 18 to 64 has at least one medical condition that might be due to COVID-19 .
How many times can a person get COVID-19?
Maybe you thought it was like chickenpox — if youve had it once, youre immune forever, and you can put your worries away for good. Unfortunately, thats not the case. You can get COVID-19 more than once. Many times, in fact.
What are the side effects of the new COVID-19 booster?
Side effects are not expected to differ from those associated with the current vaccine, which include redness and swelling at the vaccine site, as well as occasional fatigue, headache and muscle soreness, according to the CDC. More serious reactions are rare.
What side effects besides pain at the injection site are reported after receiving the updated COVID-19 booster vaccination?
About 80 percent of trial participants reported it, followed by fatigue, headache, muscle and joint pain, chills, nausea and vomiting, and fever.
Will a COVID-19 vaccine alter my DNA?
No. COVID-19 mRNA vaccines do not change or interact with your DNA in any way.
Does the COVID-19 vaccine have a live virus?
None of the vaccines authorized for use in the U.S. contain a live virus. mRNA and viral vector vaccines are the two types of currently authorized COVID-19 vaccines available.
How long has the mRNA vaccine been around?
mRNA vaccines have been studied before for flu, Zika, rabies, and cytomegalovirus (CMV). As soon as the necessary information about the virus that causes COVID-19 was available, scientists began designing the mRNA instructions for cells to build the unique spike protein into an mRNA vaccine.
Who is the scientist that developed the Pfizer COVID-19 vaccine?
Katalin Kariko, PhD, a senior vice president at BioNTech, and Drew Weissman, MD, PhD, a professor in vaccine research at the University of Pennsylvania, Philadelphia, Pennsylvania, made a breakthrough discovery by modifying messenger RNA (mRNA), which provides instructions to cells to make proteins.
When should I get the new bivalent Omicron COVID-19 booster?
You should take the bivalent booster as soon as you can. The variants targeted by the updated bivalent booster (Omicron BA.4/5) are expected to continue to circulate throughout the U.S.
Is the new omicron Pfizer-BioNTech and Moderna COVID-19 booster shot available?
The Centers for Disease Control and Prevention is recommending updated COVID boosters, for people ages 12 and older. These newly authorized shots are reformulated versions of the Moderna and Pfizer-BioNTech COVID-19 vaccines and theyre available at pharmacies, clinics and doctors offices around the country.
What are the average ages of people who had myocarditis after mRNA-based COVID-19 vaccination during the first 8 months of 2021?
Of the 1626 reports that met the CDCs case definition for myocarditis, 1195 (73%) were younger than 30 years of age, 543 (33%) were younger than 18 years of age, and the median age was 21 years (IQR, 16-31 years) (Figure 1).
Are there any COVID-19 vaccines linked to myocarditis?
Only the mRNA vaccines (Pfizer-BioNTech and Moderna) have been linked with myocarditis. Myocarditis related to COVID-19 vaccines seems to be caused by the body’s immune response to vaccination.
Which organ system is most often affected by COVID-19?
COVID-19 is a disease caused by SARS-CoV-2 that can trigger what doctors call a respiratory tract infection. It can affect your upper respiratory tract (sinuses, nose, and throat) or lower respiratory tract (windpipe and lungs).
Can you be infected with COVID-19 twice?
It’s possible. Research shows you can get it twice. Even more than twice, in some cases.
Can you get reinfected with COVID-19?
Reinfection with the virus that causes COVID-19 means a person was infected, recovered, and then later became infected again. After recovering from COVID-19, most individuals will have some protection from repeat infections. However, reinfections do occur after COVID-19.
