The Food and Drug Administration (FDA) added heart inflammation warnings to information about the Pfizer and Moderna Covid-19 injections.

The warning was added after thousands of vaccinated young adults and children around the world were diagnosed with myocarditis (inflammation of the heart muscle) and pericarditis (inflammation of the membrane lining the heart).

Both heart conditions can be fatal and require immediate medical attention. Heart inflammation was diagnosed in people under age 30, including at least 1,200 young adults and children in America.

The Pfizer and Moderna shots use mRNA spike protein technology and require two injections, while the Johnson & Johnson shot uses an adenovirus and requires a single dose.

In related news, the World Health Organization (WHO) is recommending face masks for everyone - vaccinated and unvaccinated - due to the spread of the so-called Covid "delta" variant.

"Vaccine alone won't stop community transmission," the WHO's Dr. Mariangela Simao said.

"People need to continue to use masks consistently, be in ventilated spaces, hand hygiene ... the physical distance, avoid crowding. This still continues to be extremely important, even if you're vaccinated when you have a community transmission ongoing."

Most Americans stopped wearing face masks and face coverings in May, after the Centers for Disease Control issued new guidelines for people who are fully vaccinated.

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.

Dr. Thomas Clark, a CDC epidemiologist, reported the data to the Advisory Committee on Immunization Practices on Saturday (click link to see the reported data).

CDC

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.

Darryl Rowe

A British hairdresser was sentenced to life in prison for deliberately infecting 5 men with the virus that cause AIDS. Daryll Rowe was sentenced Wednesday in Brighton, England for attempting to infect as many as 10 men with the HIV virus.

Rowe reportedly taunted the men with text messages that said, "I have HIV. Oops".
