The FDA has issued an Emergency Use Authorization
(EUA) for the long-acting investigational IV
monoclonal antibody pemivibart (Pemgarda –
Invivyd) for pre-exposure prophylaxis of COVID-19
in persons ≥12 years old (weight ≥40 kg) who have
moderate to severe immune compromise and
are unlikely to respond adequately to COVID-19
vaccination (see Table 1). Pemgarda is the only drug
that is currently authorized in the US for pre-exposure
prophylaxis of COVID-19. Tixagevimab/cilgavimab
(Evusheld) was previously available under an EUA for
this indication, but it lacks activity against currently
circulating SARS-CoV-2 variants.

A new 2023-2024 formulation of the adjuvanted
protein subunit COVID-19 vaccine manufactured by
Novavax that was developed to more closely target
currently circulating SARS-CoV-2 variants has been
made available in the US under an FDA Emergency Use Authorization (EUA) for use in persons ≥12
years old. The original formulation of the Novavax
vaccine is no longer authorized for use in the US.
In September, updated formulations of the mRNA
COVID-19 vaccines manufactured by Pfizer/BioNTech (Comirnaty) and Moderna (Spikevax) were
licensed by the FDA for use in persons ≥12 years old
and made available under EUAs for use in persons
6 months to 11 years old.

The FDA has expanded its Emergency Use
Authorization (EUA) for the COVID-19 vaccine
manufactured by Pfizer/BioNTech (Comirnaty) to
permit use of the bivalent formulation (containing
mRNA from the original and BA.4/5 Omicron strains of

to 4 years old who completed the primary series with
3 doses of the monovalent formulation ≥2 months
previously. The Pfizer bivalent vaccine had previously
been authorized for use as a booster dose in persons
≥5 years old and as a third primary dose in children 6
months to 4 years old. Booster doses of the Moderna bivalent COVID-19 vaccine (Spikevax) for children
6 months to 5 years old were authorized earlier.

Three products are currently available in the US for
treatment of high-risk,1 nonhospitalized adults with
mild to moderate COVID-19: oral ritonavir-boosted
nirmatrelvir (Paxlovid), IV remdesivir (Veklury), and
oral molnupiravir (Lagevrio). Remdesivir is FDA-approved
for such use; nirmatrelvir/ritonavir and
molnupiravir are available under an FDA Emergency
Use Authorization. Because the pivotal clinical trials
of these products for outpatient use were conducted
in patients who were not vaccinated against
COVID-19, some clinicians have questioned whether
they can benefit vaccinated outpatients.

The CDC has issued new guidance allowing for
an interval of up to 8 weeks between the first and
second primary doses of an mRNA COVID-19 vaccine
in certain patients 12-64 years old.1 Product labeling
currently recommends a 3-week interval between the
first two doses of the Pfizer/BioNTech mRNA vaccine
(Comirnaty) and a 4-week interval between the first
two doses of the Moderna mRNA vaccine (Spikevax).
The new guidance is based on data suggesting that
a longer interval can decrease the risk of myocarditis

The IV antiviral drug remdesivir (Veklury – Gilead)
has been available for treatment of COVID-19 in
hospitalized patients since 2020. Now, the FDA has
approved remdesivir for treatment of mild to moderate
COVID-19 in outpatients ≥12 years old who weigh
≥40 kg and are at high risk for progression to severe
disease, including hospitalization or death; they
also issued an Emergency Use Authorization (EUA)
allowing its use in any other high-risk outpatient who
weighs ≥3.5 kg.

On December 22, 2021, the FDA issued an Emergency
Use Authorization (EUA) for the investigational
antiviral drug nirmatrelvir copackaged with the HIV-1
protease inhibitor ritonavir (Paxlovid – Pfizer) for
oral treatment of mild to moderate COVID-19 in
outpatients ≥12 years old who weigh at least 40 kg
and are at high risk of progressing to severe disease,
including hospitalization or death. Paxlovid was the
first oral antiviral drug to be authorized in the US for
treatment of COVID-19; Merck's oral antiviral drug
molnupiravir was granted an EUA for treatment of
COVID-19 on December 23, 2021. The
IV antiviral drug remdesivir (Veklury) was approved
by the FDA in 2020 for treatment of COVID-19 in
hospitalized patients.

of a booster dose for all adults ≥18 years old after
primary immunization with either the same COVID-19
vaccine or a different one. Booster doses of these
vaccines were previously authorized only for select
populations (age ≥65 years or persons at high risk for
severe COVID-19). The EUA for the adenovirus-based

On September 22, on the advice of its Vaccines and
Related Biologic Products Advisory Committee, the
FDA expanded the Emergency Use Authorization
(EUA) for the Pfizer/BioNTech mRNA-based COVID-19
vaccine (Comirnaty) to include administration of a
booster dose ≥6 months after a 2-dose primary series
in adults who are ≥65 years old or at high risk for severe
COVID-19 because of an underlying medical condition
or frequent institutional or occupational exposure
to SARS-CoV-2 (see Table 1). The FDA Advisory
Committee recommended against authorization of a
booster dose of Comirnaty for all persons ≥16 years
old, citing a lack of adequate data.

In February 2021, the FDA issued an Emergency Use
Authorization (EUA) for the investigational monoclonal
antibodies bamlanivimab and etesevimab (Lilly) for
use together to treat mild to moderate COVID-19
in persons ≥12 years old who weigh ≥40 kg and
are at high risk of progression to severe disease or
hospitalization. The FDA has now expanded this
EUA to allow use of the antibodies together for post-exposure
prophylaxis of COVID-19 in such persons
if they are not fully vaccinated against COVID-19 or
are unlikely to have an adequate immune response
to full vaccination and have been in close contact
with a SARS-CoV-2-infected individual or are likely
to be exposed to SARS-CoV-2 in the setting of an
institutional outbreak (see Table 1). Bamlanivimab
plus etesevimab is the second monoclonal antibody
combination to receive an EUA for post-exposure
prophylaxis of COVID-19; casirivimab plus imdevimab
(REGEN-COV) was authorized earlier.

The investigational monoclonal antibody sotrovimab
(VIR-7831; GSK/Vir Biotechnology) has been granted
an FDA Emergency Use Authorization (EUA) for
treatment of mild to moderate COVID-19 in patients
≥12 years old who weigh ≥40 kg and are at high
risk of progressing to severe disease, including
hospitalization and death.1 Two other monoclonal
antibody regimens are authorized for the same
indication: casirivimab (REGN10933) and imdevimab
(REGN10987) administered together, and bamlanivimab (LY-CoV555) and etesevimab (LYCoV016)
administered together.
The FDA revoked its EUA
for bamlanivimab alone in April 2021 because an
increasing percentage of COVID-19 cases in the US
are being caused by SARS-CoV-2 variants that are
resistant to monotherapy with the drug.

On April 23, 2021, on advice from the Advisory
Committee on Immunization Practices (ACIP), the
FDA and CDC recommended that use of the Johnson
& Johnson adenovirus-based COVID-19 vaccine
resume despite its association with development of
thrombosis with thrombocytopenia syndrome (TTS).
Administration of the vaccine had been paused on April
13 because of 6 reports of TTS, but after completing a
data review that identified a further 9 cases associated
with the formulation, the agencies concluded that the
benefits of the vaccine outweighed its risks. About
7.98 million doses of the single-dose vaccine had been
administered in the US at the time of the review.
