The Centers for Disease Control (CDC) issued new guidance after thousands of people reported adverse side effects after getting the new mRNA Covid-19 vaccine.
As of Dec. 18, 3,150 people reported what the agency terms "Health Impact Events" after getting vaccinated. The CDC defines "Health Impact Events" as "unable to perform normal daily activities, unable to work," or "required care from a doctor or health care professional."
The adverse effects were reported through V-safe, a smartphone app, according to theepochtimes.com.
The CDC recommends not taking the vaccine if a person has "ever had a severe allergic reaction to any ingredient in a Covid-19 vaccine."
The active ingredient in the Covid-19 vaccine is 30 mcg of modified messenger ribonucleic acid (modRNA) which contains encoding of spike protein (glycoprotein of SARS-CoV-2).
The encoding tells human cells to produce a spike protein of SARS-CoV-2 that acts as an antigen (kind of like a virus) to stimulate an immune response and create antibodies.
The amount of mRNA contained in the first injection is less than a grain of table salt. A second injection is required within 21 days of the first shot.
Other ingredients include lipids, salts, sugar (6 mg sucrose) and polyethylene glycol as a purifier.
The CDC recommends that people with a history of severe allergic reactions not related to vaccines or injectable medications can still get the mRNA vaccine.
