A fourth COVID-19 vaccine dose? Moderna seeks DFA authorization for additional booster shot for all adults

Drugmaker Moderna requested the Meals and Drug Administration on Thursday to authorize a fourth shot of its COVID-19 vaccine as a booster dose for all adults.

The request is broader than rival pharmaceutical firm Pfizer’s request earlier this week for the regulator to approve a booster shot for all seniors.

In a press launch, the corporate stated its request for approval for all adults was made “to offer flexibility” to the Facilities for Illness Management and Prevention and medical suppliers to find out the “acceptable use” of a second booster dose of the mRNA vaccine, “together with for these at larger danger of COVID-19 attributable to age or comorbidities.”

US officers have been laying the groundwork to ship further booster doses to shore up the vaccines’ safety towards critical illness and dying from COVID-19. The White Home has been sounding the alarm that it wants Congress to “urgently” approve extra funding for the federal authorities to safe extra doses of the COVID-19 vaccines, both for extra booster photographs or variant-specific immunizations.

US well being officers at present advocate a main sequence of two doses of the Moderna vaccine and a booster dose months later.

Moderna stated its request for an extra dose was based mostly on “lately revealed information generated in the US and Israel following the emergence of Omicron.”

On Tuesday, Pfizer and its companion BioNTech requested US regulators to authorize an extra booster dose of their COVID-19 vaccine for seniors, saying information from Israel suggests older adults would profit.
