The Centers for Disease Control and Prevention is set to meet on Friday to discuss whether rare instances of a heart disorder merit changing its recommendations for vaccinating teenagers with the Pfizer vaccine.
The scientist at the center of the storm can't disprove that the virus resulted from a lab leak in China -- though he doesn't believe it.
“We need to take care of the problem everywhere to be able to take care of it anywhere,” says Dr. Mark Feinberg, president and CEO of the International AIDS Vaccine Initiative.
Though the vaccine appears to offer a high level of protection, it's not clear how long immunity would last and whether the vaccine might cause any health problems. No serious side effects have been noted but it's early days yet.
If there is a silver lining to the flawed U.S. response to the coronavirus pandemic, it is this: The relatively high number of new cases being diagnosed daily — upward of 20,000 — will make it easier to test new vaccines.
