DR. Scott Gottlieb said Monday he was not yet concerned about the number of Americans who missed their scheduled second dose of Covid vaccine.
“We’re not sure if these people will come back anytime. They just didn’t come back on time,” the former Food and Drug Administration commissioner said in an interview on CNBCs “Squawk Box.”
However, Gottlieb said receiving the second Covid shot is necessary to receive the full protective benefits of the vaccines for months to come. The Pfizer– –BioNTech and Moderna Vaccines require two shots. ((Johnson & JohnsonThe Covid vaccine, the third emergency approved in the US, only takes a single dose.)
“My advice to everyone would be that we do not know how long this reaction will last, even if you are young and there is evidence that you are already developing a robust immune response with this first dose,” said Gottlieb, who sits on Pfizer’s board of directors. “If you really want the vaccine to work over the long term, you really should get the second dose.”
On Friday, the White House chief medical officer, Dr. Anthony Fauci that approximately 8% of US residents received the first dose of the Pfizer or Moderna vaccines didn’t come back for the second shot.
“The number of people who have not yet returned to the second dose is low compared to historical standards or historical norms,” said Gottlieb, who headed the FDA in the Trump administration from 2017 to 2019. For example, he said, the response rate for the Covid vaccine is better than the one Two-dose shingles vaccine.
Gottlieb admitted that it is possible that a higher percentage of US vaccine recipients could skip the second shot if more young people get the shot. This is partly because “younger people know they can derive a more robust immune response from just the first dose than older people, who really need that second dose to get full immune protection,” he said.
People who didn’t return for the second shot aren’t necessarily doing something wrong on purpose, Gottlieb added. He praised the pharmacies that deliver vaccines for “trying to implement reminders for these patients.”
“Often it is only lost for tracking. It is not people who purposely do not come back,” said Gottlieb. “There are some situations I’ve spoken to people who are worried about the second dose, the side effects that are supposedly associated with the second dose compared to the first dose. But right now the percentage of people who came back are because this second shot is pretty high. “
Nearly 105 million people in the US, nearly a third of the population, have been fully vaccinated, according to the latest data from tThe Centers for Disease Control and Prevention. Approximately 147 million people, roughly 44% of the US population, received at least one dose, the CDC data said.
