“We know that infection doesn’t induce a very strong immune response, and it wanes over time,” Slaoui said.
Slaoui said it is safe for people who were infected with Covid-19 to get a vaccine.
“That has happened in the clinical trials,” he said. “People participating in the trial had experienced, or actively had, a viral infection at the time they started being vaccinated, so it’s safe.”
Covid-19 vaccinations are underway for health care workers and residents of long term care facilities. The Centers for Disease Control and Prevention is expected to discuss the next groups recommended to be vaccinated at a meeting Sunday afternoon.
