“We generally recommend that the booster dose be of the kind you initially received,” the director of the National Institute of Allergy and Infectious Diseases said in an interview with CNN.
“But for one reason or another, maybe different circumstances impose themselves, whether in terms of species availability or just personal reasons, then you can receive a different species,” he added.
On Thursday, the US Centers for Disease Control and Prevention recommended that the population take booster doses of the Covid-19 vaccine for those who received doses of Moderna and Johnson & Johnson, and said that it is possible to choose a different vaccine than what they previously received.
The recommendations opened the door for recipients of a single dose of Johnson & Johnson to take a dose of the Pfizer or Moderna vaccines, which have shown greater protection in several studies.
