5.1 Management Of Acute Allergic Reactions
Appropriate medical treatment used to manage immediate allergic reactions must be immediately available in the event an anaphylactic reaction occurs following administration of ABRYSVO.
5.2 Syncope
Syncope (fainting) may occur in association with administration of injectable vaccines, including ABRYSVO. Procedures should be in place to avoid injury from fainting.
5.3 Altered Immunocompetence
Immunocompromised individuals, including those receiving immunosuppressive therapy, may have a diminished immune response to ABRYSVO.
5.4 Limitations Of Vaccine Effectiveness
Vaccination with ABRYSVO may not protect all vaccine recipients.
6 Adverse Reactions
In clinical trials, the most commonly reported (≥10%) adverse reactions were fatigue (15.5%), headache (12.8%), pain at the injection site (10.5%), and muscle pain (10.1%).
6.1 Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a vaccine cannot be directly compared to rates in the clinical trials of another vaccine and may not reflect the rates observed in practice.
The safety of ABRYSVO was evaluated in Study 1 (NCT05035212) in which 17,215 participants received ABRYSVO and 17,069 received placebo (0.5 mL dose, containing the same buffer ingredients in the same quantities as in a single dose of ABRYSVO [see Description (11)]). Study 1 is an ongoing Phase 3, multicenter, randomized, double-blind, placebo-controlled study to assess the efficacy and safety of ABRYSVO in individuals 60 years of age and older. This study is being conducted in the USA, South Africa, Japan, Canada, Finland, the Netherlands, and Argentina. Demographic characteristics among participants who received ABRYSVO and those who received placebo were generally similar with regard to age, sex, race, and ethnicity. Of the participants in the study, 51% were male and 78% were White, 13% were Black or African American, and 37% were Hispanic/Latino. The median age of participants was 67 years (range 59-97 years).
Solicited local and systemic reactions were collected using electronic diaries for 7 days after study vaccination in 7,169 participants (3,630 ABRYSVO participants and 3,539 placebo recipients) from a subset of sites. For all participants, unsolicited adverse events were collected for one month after study vaccination; serious adverse events (SAEs) are collected throughout study participation.

Unsolicited Adverse Events in Study 1
Unsolicited adverse events occurring within 1 month after vaccination were similar between groups, reported in 8.9% and 8.5% of participants who received ABRYSVO and placebo, respectively.
Within 30 days after vaccination, atrial fibrillation was reported in 10 vaccine recipients and 4 placebo recipients (of which 4 in the ABRYSVO group and 3 in the placebo group were serious adverse events); the onset of symptoms was 18 to 30 days post vaccination. The currently available information on atrial fibrillation is insufficient to determine a causal relationship to the vaccine. There were no other notable patterns or numerical imbalances between groups for specific categories of unsolicited adverse events.
Serious Adverse Events in Study 1
In Study 1, SAEs were reported by 2.3% of participants in both the ABRYSVO and placebo groups. Three participants in the ABRYSVO group had SAEs which were assessed as possibly related to study vaccination: Guillain-Barre Syndrome reported 7 days after vaccination, Miller Fisher Syndrome reported 8 days after vaccination, and hypersensitivity reported 8 hours after vaccination.
Risk Summary
All pregnancies have a risk of birth defect, loss, or other adverse outcomes. In the US general population, the estimated background risk of major birth defects and miscarriages in clinically recognized pregnancies is 2% to 4%, and 15% to 20%, respectively, and the estimated background risk of fetal deaths after 20 weeks is 0.6%. ABRYSVO is not approved for use in individuals younger than 60 years of age.
Data from a clinical trial (NCT04424316) that enrolled pregnant individuals who were randomly assigned 1:1 to receive ABRYSVO or placebo (0.5 mL dose, containing the same buffer ingredients in the same quantities as in a single dose of ABRYSVO [see Description (11)]) at 24 through 36 weeks’ gestation revealed no evidence for vaccine-associated increase in the risk of congenital anomalies or fetal deaths. In this study, there was a numerical imbalance in preterm births, with more preterm infants born to individuals in the ABRYSVO group compared to individuals in the placebo group (see Human Data).
A developmental and reproductive toxicity study was performed in female rabbits administered a vaccine formulation containing two times the antigen content of a single human dose of ABRYSVO prior to and during gestation. The study showed no evidence of harm to the fetus or to postnatal survival, growth, or development (see Animal Data).
Data
Human Data
In a randomized controlled clinical trial (NCT04424316), 3,682 pregnant individuals received ABRYSVO and 3,676 received placebo (0.5 mL dose, containing the same buffer ingredients in the same quantities as in a single dose of ABRYSVO [see Description (11)]) at 24 through 36 weeks’ gestation. The infant safety population included 3,568 and 3,558 infants born to individuals in the ABRYSVO or placebo group, respectively. Among the infants born to individuals in the ABRYSVO group and in the placebo group, 202 (5.7%) and 169 (4.7%), respectively, were born prematurely and 174 (4.9%) and 203 (5.7%), respectively, had reported congenital malformations or anomalies. There were 10 (0.3%) fetal deaths in the ABRYSVO group and 8 (0.2%) in the placebo group.
Animal Data
A developmental toxicity study was performed in female New Zealand White rabbits. Rabbits were administered 4 doses by intramuscular injection: at 3 weeks and at 1 week prior to mating, and on gestation days 10 and 24. On each occasion, rabbits received 0.5 mL of a vaccine formulation containing twice the antigen content of F glycoproteins of RSV A and RSV B (120 mcg RSV preF A and 120 mcg RSV preF B), stabilized in prefusion conformation as contained in a single human dose of ABRYSVO [see Description (11)]. No adverse effects on mating, female fertility, or on embryo/fetal or post-natal survival, growth, or development were observed. There were no vaccine-related fetal malformations or variations.
Risk Summary
It is not known whether ABRYSVO is excreted in human milk. Data are not available to assess the effects of ABRYSVO on the breastfed infant or on milk production/excretion. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for ABRYSVO and any potential adverse effects on the breastfed child from ABRYSVO or from the underlying maternal condition. For preventative vaccines, the underlying maternal condition is susceptibility to disease prevented by the vaccine. ABRYSVO is not approved for use in individuals younger than 60 years of age.
Storage After Reconstitution
After reconstitution, administer ABRYSVO immediately or store at room temperature [15°C to 30°C (59°F to 86°F)] and use within 4 hours. Do not store reconstituted vaccine under refrigerated conditions [2°C to 8°C (36°F to 46°F)]. Do not freeze reconstituted vaccine.

8.4 Pediatric Use
The safety and effectiveness of ABRYSVO in individuals younger than 18 years of age have not been established.
8.5 Geriatric Use
ABRYSVO is approved for use in individuals 60 years of age and older. In Study 1, of the 17,215 recipients who received ABRYSVO 62% (n=10,756) were aged 60-69 years of age, 32% (n=5,488) were 70-79 years of age and 6% (n=970) were ≥80 years of age [see Adverse Reactions (6.1) and Clinical Studies (14.1)].
11 Description
ABRYSVO (Respiratory Syncytial Virus Vaccine) is a sterile solution for intramuscular injection. The vaccine is supplied as a vial of Lyophilized Antigen Component that is reconstituted at the time of use with a Sterile Water Diluent Component. The antigen component contains recombinant RSV preF A and RSV preF B.
The RSV preF A and RSV preF B recombinant proteins are expressed in genetically engineered Chinese Hamster Ovary cell lines grown in suspension culture using chemically-defined media, without antibiotics or animal-derived components. The recombinant proteins are purified through a series of column chromatography and filtration steps followed by formulation, filling into vials, and lyophilization.
After reconstitution, each dose of ABRYSVO is approximately 0.5 mL. The vaccine is formulated to contain 120 mcg of RSV stabilized prefusion F proteins (60 mcg RSV preF A and 60 mcg RSV preF B) per 0.5 mL. ABRYSVO also contains the following buffer ingredients: 0.11 mg tromethamine, 1.04 mg tromethamine hydrochloride, 11.3 mg sucrose, 22.5 mg mannitol, 0.08 mg polysorbate 80, and 1.1 mg sodium chloride per 0.5 mL. ABRYSVO is a sterile, clear, and colorless solution.
ABRYSVO contains no preservatives. Each dose may also contain residual amounts of host cell proteins (≤0.1% w/w) and DNA (<0.4 ng/mg of total protein) from the manufacturing process.
The vial stopper and tip cap and rubber plunger of the prefilled syringe are not made with natural rubber latex.
12.1 Mechanism Of Action
ABRYSVO induces an immune response against RSV pre F that protects against lower respiratory tract disease caused by RSV.
13.1 Carcinogenesis, Mutagenesis, Impairment Of Fertility
ABRYSVO has not been evaluated for the potential to cause carcinogenicity, genotoxicity, or impairment of male fertility. A developmental and reproductive toxicity study in female rabbits revealed no evidence of impaired female fertility [see Use in Specific Populations (8.1)].
14.1 Efficacy In Individuals 60 Years Of Age And Older
Study 1 is an ongoing Phase 3, multicenter, randomized, double-blind, placebo-controlled study to assess the efficacy and safety of ABRYSVO in the prevention of RSV-associated lower respiratory tract disease in individuals 60 years of age and older. Participants are planned to be followed for up to two RSV seasons, approximately 25 months.
Participants were randomized (1:1) to receive ABRYSVO (n=17,197) or placebo (n=17,186). Randomization was stratified by age, 60-69 years (n=21,499, 63%), 70-79 years (n=10,948, 32%), and ≥80 years (n=1,934, 6%). Healthy adults and adults with stable chronic diseases were included. Among enrolled participants 15% had stable chronic cardiopulmonary conditions such as chronic obstructive pulmonary disease (COPD), asthma, or congestive heart failure (CHF).
Starting 14 days after study vaccination (study Day 15), all participants were actively monitored for onset of acute respiratory illness (ARI) symptoms: new or increased sore throat, nasal congestion, nasal discharge, cough, wheezing, sputum production, or shortness of breath. If the participant experienced 1 or more ARI symptoms, a mid-turbinate nasal swab was collected within 7 days of onset of symptoms and tested by reverse transcriptase polymerase chain reaction (RT-PCR) for RSV.
RSV-associated lower respiratory tract disease (RSV-LRTD) was evaluated in Study 1. A case of RSV-LRTD was defined as an RT-PCR confirmed RSV illness with two or more, or three or more, of the following respiratory symptoms within 7 days of symptom onset and lasting more than 1 day during the same illness: new or increased cough, wheezing, sputum production, shortness of breath, or tachypnea (≥25 breaths/min or 15% increase from resting baseline). A case of RSV-associated severe lower respiratory tract disease was defined as a case meeting the RSV-LRTD criteria plus at least one of the following: hospitalization due to RSV-LRTD, new or increased oxygen supplementation, or mechanical ventilation including Continuous Positive Airway Pressure (CPAP).
Efficacy against Respiratory Syncytial Virus-associated Lower Respiratory Tract Disease
Vaccine efficacy (VE), against RSV-LRTD, defined as the relative risk reduction of first episode of RSV-LRTD in the ABRYSVO group compared to the placebo group in the first RSV season, was assessed.
The study met the pre-specified success criteria for demonstration of efficacy of ABRYSVO for the primary objectives of prevention of RSV-LRTD with ≥2 symptoms and prevention of RSV-LRTD with ≥3 symptoms. The median duration of follow-up for efficacy was 7 months.
Vaccine efficacy information is presented in Table 3.
CI – confidence interval; N – number of participants; n = number of cases; RSV – respiratory syncytial virus; VE – vaccine efficacy (VE based on case count ratio is calculated as 1-(P/[1-P]), where P is the number of RSVpreF cases divided by the total number of cases) | |||
Efficacy Endpoint | ABRYSVO N=16,306 Evaluable efficacy population n | Placebo N=16,308 n | VE (%) (96.66% CI) |
First episode of RSV-associated lower respiratory tract disease with ≥2 symptoms | 11 | 33 | 66.7 (28.8, 85.8) |
First episode of RSV-associated lower respiratory tract disease with ≥3 symptoms | 2 | 14 | 85.7 (32.0, 98.7) |
There were 2 cases of RSV associated severe lower respiratory tract disease in the placebo group and no cases in the ABRYSVO group.
