How long has the mRNA vaccine been around?
Is there a live virus in the mRNA COVID-19 vaccines?
How is the Moderna COVID-19 vaccine similar to the Pfizer vaccine?
Moderna’s vaccine was authorized for emergency use in the U.S. last December, about a week after the Pfizer vaccine. Moderna uses the same mRNA technology as Pfizer and has a similarly high efficacy at preventing symptomatic disease.
Can you get the mRNA COVID-19 vaccine if you are allergic to the ingredient in the vaccine?
If you are allergic to an ingredient in a COVID-19 vaccine
If you have had a severe allergic reaction or an immediate allergic reaction—even if it was not severe—to any ingredient in an mRNA COVID-19 vaccine, you should not get either of the currently available mRNA COVID-19 vaccines (Pfizer-BioNTech and Moderna).
Is the COVID-19 vaccine a live or inactivated vaccine?
Neither the mRNA (Moderna and Pfizer) nor adenovirus (J&J/Janssen and AstraZeneca) vaccines contain live virus. Each of these contain a single gene from the virus that causes COVID-19.
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.
Should you take the J&J COVID-19 vaccine if you are allergic to it?
If you have had a severe allergic reaction or an immediate allergic reaction to any ingredient in Johnson & Johnson’s Janssen (J&J/Janssen) COVID-19 vaccine, you should not get the J&J/Janssen vaccine.
How do you know if you are allergic to the COVID-19 vaccine?
An immediate allergic reaction happens within 4 hours after getting vaccinated and could include symptoms such as hives, swelling, and wheezing (respiratory distress).
Who should not take the Pfizer-BioNTech COVID-19 vaccine?
If you have had a severe allergic reaction to any ingredient in the Pfizer-BioNTech COVID-19 vaccine (such as polyethylene glycol), you should not get this vaccine. If you had a severe allergic reaction after getting a dose of the Pfizer-BioNTech COVID-19 vaccine, you should not get another dose of an mRNA vaccine.
What are the ingredients in the Janssen COVID-19 vaccine?
What are the common side effects of the Janssen COVID-19 vaccine?
Does Johnson and Johnson COVID-19 vaccine have egg by product in it?
No food proteins like eggs or egg products, gluten, peanuts, tree nuts, nut products, or any nut byproducts (COVID-19 vaccines are not manufactured in facilities that produce food products).
How effective is the J&J Janssen COVID-19 vaccine?
The J&J/Janssen COVID-19 Vaccine was 66.3% effective in clinical trials (efficacy) at preventing laboratory-confirmed COVID-19 infection in people who received the vaccine and had no evidence of being previously infected. People had the most protection 2 weeks after getting vaccinated.
Are egg products used in COVID-19 vaccines?
The COVID-19 vaccines currently authorized by the FDA are not manufactured using egg products or egg culture. See COVID-19 vaccines for more information.
Does COVID-19 vaccine increase your blood sugar?
There is no known interaction with the vaccine and diabetes medications, so it is important to continue on your medications and insulin. Some patients with diabetes experience higher blood sugars for 1-7 days or more after the vaccine, so monitor your blood sugars very closely after vaccination.
Does the Single-shot Janssen/Johnson & Johnson COVID-19 vaccine produce a strong immune response?
•The immune response to the single-shot Janssen/Johnson & Johnson COVID-19 vaccine remained robust against variants of SARS-CoV-2.•Although the vaccine produced fewer neutralizing antibodies against the variants than the original virus, the overall immune response suggests strong protection.
How does the Johnson and Johnson COVID-19 vaccine work?
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.
Can you get Pfizer or Moderna vaccine after the Johnson & Johnson COVID-19 vaccine?
If you got J & J as your initial vaccine and are 18 or older, you are eligible for a booster shot two months later, regardless of which one you choose (you’re eligible six months later if you had Moderna or Pfizer-BioNTech as your primary series).
