How does the mRNA from the COVID-19 vaccine work?
Messenger RNA is a type of RNA that is necessary for protein production. In cells, mRNA uses the information in genes to create a blueprint for making proteins. Once cells finish making a protein, they quickly break down the mRNA. mRNA from vaccines does not enter the nucleus and does not alter DNA.
Is there a live virus in the mRNA COVID-19 vaccines?
The mRNA vaccines do not contain any live virus. Instead, they work by teaching our cells to make a harmless piece of a “spike protein,” which is found on the surface of the virus that causes COVID-19. After making the protein piece, cells display it on their surface.
Will a COVID-19 vaccine alter my DNA?
No. COVID-19 mRNA vaccines do not change or interact with your DNA in any way.
Are there any safety concerns concerning mRNA technology of the Pfizer-BioNTech COVID-19 Vaccine?
FDA does not have specific safety concerns with a vaccine that utilizes this technology.
What does the COVID-19 vaccine do in your body?
COVID-19 vaccines teach our immune systems how to recognize and fight the virus that causes COVID-19. Sometimes this process can cause symptoms, such as fever.
What are the common side effects of the Moderna COVID-19 vaccine?
The most commonly reported side effects were pain at the injection site, tiredness, headache, muscle pain, chills, joint pain, nausea and vomiting, swollen lymph nodes in the same arm of the injection and fever. Side effects typically started within two days of vaccination and resolved two or three days later.
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.
Does the mRNA covid-19 vaccine have eggs or gelatin?
In addition, because the mRNA COVID-19 vaccines do not contain eggs or gelatin, persons with allergies to these substances do not have a contraindication or precaution to vaccination.
Are you more likely to have side effects from the Pfizer and Moderna COVID-19 vaccines if you had COVID-19?
Both the Pfizer and the Moderna COVID-19 vaccinations involve two injections separated by several weeks. For these two-shot vaccinations: If you had COVID-19 before being vaccinated, the first injection may cause more noticeable side effects than for people who have not had the coronavirus.
Has there been any serious adverse events as a result of taking the Pfizer-BioNTech COVID-19 Vaccine?
Serious adverse events, while uncommon (<1.0\%), were observed at slightly higher numerical rates in the vaccine study group compared to the saline placebo study group, both overall and for certain specific adverse events occurring in very small numbers.
How does the COVID-19 vaccine boost your immune system?
Vaccines work by stimulating your immune system to produce antibodies, exactly like it would if you were exposed to the disease. After getting vaccinated, you develop immunity to that disease, without having to get the disease first.
How long will it take to build immunity after getting the COVID-19 vaccine?
It takes time for your body to build protection after any vaccination. People are considered fully vaccinated two weeks after their second shot of the Pfizer-BioNtech or Moderna COVID-19 vaccine, or two weeks after the single-dose J&J/Janssen COVID-19 vaccine.
