Pfizer and Moderna aim to keep up with a shift in the U.S. toward annual Covid shots rather than frequent booster doses.
Pfizer’s and Moderna’s Covid vaccines both deliver robust protection against the virus, but that immunity can start to fade after four to six months.
Regulators are transitioning toward a flu shot-like model for Covid vaccines, meaning people will get a single shot every year that is updated annually to target the latest variant expected to circulate in the fall and winter.
“The vaccine became proof of the value of mRNA in a pandemic when you need to make something quickly,” Miller told CNBC.
An annual schedule may help people view Covid shots as another “very natural part” of protecting their health and encourage more of them to vaccinate each year, according to Dolsten.
People didn’t want to wear them at first, but over time they realized how much seat belts protect them. Now everyone uses them today,” Dolsten told CNBC. “That’s kind of how the vaccine story needs to be reimagined.”
