The Centers for Disease Control and Prevention (CDC) continues to recommend that all eligible adults, adolescents, and children 5 and older be up to date on their COVID-19 vaccines, which includes getting an initial booster when eligible.
On 3/29/2021, the CDC had updated its recommendations to allow individuals with moderate to severe immunocompromise as well as people over the age of 50 who received an initial booster dose at least 4 months ago to be eligible for another mRNA booster to increase their protection against severe disease from COVID-19.
It was also announced that adults who received a primary vaccine and booster dose of Johnson & Johnson’s Janssen COVID-19 vaccine at least 4 months ago may now receive a second booster dose using an mRNA COVID-19 vaccine.
These updated recommendations acknowledge the increased risk of severe disease in certain populations including those who are elderly or over the age of 50 with multiple underlying conditions, along with the currently available data on vaccine and booster effectiveness.
