San Diego — CDC is planning to hold an emergency meeting next week to discuss higher-than-expected reports of young people with heart inflammation following the second dose of Pfizer and Moderna COVID vaccine.

The CDC has received nearly 300 reports involving people between 16 and 24 years old, most of whom are men. These conditions are called myocarditis and pericarditis.

“It’s like muscle bruises and bruising of the covering around the heart,” said Dr. William Tseng, head of vaccines at Kaiser Permanente in the San Diego area.

The doctor said the cases are extremely rare, with mild symptoms, including shortness of breath and chest pain.

“Because it is very mild, if you only take ibuprofen-which is most prescriptions-you will get better, you will overcome it,” Zeng said.

Now, more than 12 million people in this age group have been fully vaccinated.

According to the Centers for Disease Control and Prevention, the vast majority of people with this disease recover easily, but dozens of people still have persistent symptoms, and some require hospitalization.

But these conditions are not directly related to vaccines.

“When the heart has side effects, it causes extra attention,” said Dr. Eric Adler, a cardiologist at the University of California San Diego Health Center. “This is not a headache. It will scare you. When someone says that your heart is inflamed, it is very scary. I can understand why parents are more anxious.”

The doctor said that despite reports, the benefits of the vaccine far outweigh the risks.

However, Adler believes that approval of vaccines for young children may now be suspended.

“I think they will still promote this process, but I think they will open their eyes even more-this will be a healthy discussion,” he said.
