Virus-like particles: a versatile and effective vaccine platform

Review

Author: Bachmann, Martin F. ; Lienert, Florian ; van Damme, Pierre ; Schwarz, Tino F.

INTRODUCTION:

Traditional live-attenuated or inactivated vaccines have limitations, including risks associated with uncontrolled replication, reduced immunogenicity, or production complexities. To address these issues, alternative platforms such as virus-like particles (VLPs) have been developed.

AREAS COVERED:

VLPs are self-assembling structures composed of viral proteins that mimic native viruses but are noninfectious. This review provides an overview of their structure, design and manufacture that make them an attractive platform for vaccine development. We then discuss the clinical development of some recently approved VLP vaccines and those widely used in immunization programs, summarizing the clinical trial data that underpins their efficacy and safety profiles. Additionally, we explore VLP vaccines in late-stage clinical development for respiratory syncytial virus and human metapneumovirus.

EXPERT OPINION:

VLPs are a versatile and promising platform for vaccine development. Their ability to mimic native viruses while eliminating the risks associated with live vaccines positions them as an attractive platform for vaccine design. Currently approved VLP vaccines demonstrate that they can provide effective protection against a wide range of diseases. Advances in VLP design and production are likely to lead to highly effective vaccines, significantly contributing to global immunization efforts.

Chikungunya virus virus-like particle vaccine safety and immunogenicity in adolescents and adults in the USA: a phase 3, randomised, double-blind, placebo-controlled trial

Article

Author: Warfield, Kelly L ; Jenkins, Victoria A ; Richardson, Jason S ; Tindale, Lauren C ; Muhammad, Sufia ; Bedell, Lisa ; Tredo, Sarah Royalty ; Mendy, Jason ; Loreth, Tobi ; Ajiboye, Patrick ; Ramanathan, Roshan ; Caso, Jorge T ; Anderson, Deborah M

BACKGROUND:

Chikungunya disease is a growing global public health concern. Vimkunya (previously chikungunya virus virus-like particle vaccine, previously PXVX0317) is a single-dose, pre-filled syringe for intramuscular injection. Here, we report safety, tolerability, and immunogenicity data for Vimkunya versus placebo in healthy adolescents and adults aged 12-64 years, and evaluate lot-to-lot consistency.

METHODS:

This pivotal phase 3, randomised, double-blind, placebo-controlled, parallel-group trial was done at 47 clinical trial sites in the USA. Eligible participants were healthy adolescents and adults aged 12-64 years. Participants were divided into three age strata (12-17 years, 18-45 years, and 46-64 years) within each site and randomly assigned (2:2:2:1) to receive one of three consecutively manufactured lots of Vimkunya or placebo (same excipient composition without chikungunya virus virus-like particle or aluminium hydroxide components) on study day 1. Neither participants, nor clinical site personnel, nor the funder knew participants' individual treatment assignments until all participants completed their involvement in the trial and the database was cleaned and locked. Participants attended a screening visit, followed by a day 1 visit that included random assignment, blood sample collection, and administration of a single dose of Vimkunya or placebo by intramuscular injection in the deltoid muscle. The coprimary endpoints were: the difference in chikungunya virus serum neutralising antibody seroreponse rate (vaccine minus placebo) at day 22; chikungunya virus serum neutralising antibody geometric mean titre (GMT) at day 22 for vaccine and placebo; and chikungunya virus serum neutralising GMT ratio at day 22 between all three pairs of vaccine lots (A:B, B:C, and A:C) in adults aged 18-45 years. The trial is registered with ClinicalTrials.gov, NCT05072080 and EudraCT, 2023-001124-42.

FINDINGS:

Between Sept 29, 2021, and Sept 23, 2022, 4215 participants were screened, of whom 3258 were eligible and enrolled (1667 [51·2%] female and 1591 [48·8%] male), and 3254 (99·9%) received either Vimkunya (n=2790) or placebo (n=464). The immunogenicity evaluable population included 2983 participants, of whom 2559 received Vimkunya and 424 received placebo. At day 22, 2503 (97·8%) of 2559 participants in the Vimkunya group had a seroresponse, compared with five (1·2%) of 424 participants in the placebo group for the immunogenicity evaluable population. The seroreponse rate difference was 96·6% (95% CI 95·0-97·5; p<0·0001). In the immunogenicity evaluable population, chikungunya virus serum neutralising antibody GMT at day 22 for the vaccine group was 1618 and for the placebo group was 7·9 (p<0·0001). At day 22, the serum neutralising GMT ratios for the pairs of lots (A:B, B:C, and A:C) were 0·98 (95% CI 0·85-1·14), 0·97 (0·84-1·12), and 0·95 (0·82-1·10), respectively. Vimkunya had a favourable safety profile; most adverse events were self-limiting and grade 1 or 2 in severity. The most common adverse events were injection site pain (656 [23·7%] of 2764 participants in the vaccine group), fatigue (551 [19·9%] of 2764), headache (498 [18·0%] of 2765), and myalgia (486 [17·6%] of 2764).

INTERPRETATION:

Vimkunya induces a rapid and robust immune response. These findings support the potential for this vaccine to protect individuals aged 12-64 years from disease caused by chikungunya virus.

BACKGROUND:

Immune responses to alphavirus vaccines might be impaired when heterologous alphavirus vaccines are administered sequentially. We aimed to compare immunogenicity and safety of a chikungunya virus virus-like particle (CHIKV VLP) vaccine in previous recipients of heterologous alphavirus vaccines with alphavirus-naive controls in the USA.

METHODS:

In this open-label, parallel-group, age-matched, sex-matched, phase 2 randomised controlled trial, which was conducted at two clinical study sites in the USA, adults (aged 18-65 years) who had previously received an investigational Venezuelan equine encephalitis virus vaccine (previous alphavirus vaccine recipients; n=30) and sex-matched and age-matched alphavirus vaccine-naive controls (n=30) were intramuscularly administered one 40 μg dose of CHIKV VLP vaccine on day 1. Immunogenicity was based on serum neutralising antibodies assessed by an in-vitro luciferase-based anti-CHIKV NT₈₀ neutralisation assay. The primary immunogenicity endpoint, which was assessed in the immunogenicity evaluable population (CHIKV VLP-vaccinated participants who had no important protocol deviations, had not received a prohibited medication, and provided evaluable serum sample results for baseline and on day 22), was to compare the proportion of previous alphavirus vaccine recipients with the proportion of alphavirus vaccine-naive controls who reached seroconversion 21 days after vaccination (ie, study day 22) with a single dose of CHIKV VLP vaccine, based on a four-fold increase of CHIKV neutralising antibodies compared with baseline. The significance of the comparison of the two groups was assessed using Fisher's exact test. The proportion with seroconversion in each group is presented with 95% CIs calculated using the Wilson method. The difference and 95% CIs for this difference was calculated based on Newcombe hybrid score method. An ANOVA model was fit with log₁₀-transformed titre as the dependent variable, and study arm, age, and sex as predictors. Least squares means, difference, and 95% CIs were back-transformed and reported as geometric mean titres (GMTs). This trial is registered with ClinicalTrials.gov, NCT03992872.

FINDINGS:

Between Nov 20, 2019, and Jan 19, 2021, 60 participants (20 [33%] female and 40 [67%] male; 40 (67%) White; median age 47·0 years [IQR 13·5]), 30 previous alphavirus vaccine recipients and 30 alphavirus vaccine-naive controls, were enrolled, vaccinated with CHIKV VLP, and completed the trial. The anti-CHIKV neutralising antibody seroconversion rate at day 22 was 100% (95% CI 88·6-100) in both groups. GMTs peaked in previous alphavirus vaccine recipients and alphavirus vaccine-naive controls at day 22 (2032·5 [95% CI 1413·0-2923·6] and 2299·2 [1598·1-3307·8], respectively) and were similar between the groups on day 22 and all subsequent visits. A higher proportion of previous alphavirus vaccine recipients (93·3% [95% CI 78·7-98·2]) had a four-fold neutralising antibody increase at day 8 than did alphavirus vaccine-naive controls (66·7% [48·8-80·8]; p=0·021). There was no statistically significant difference in the incidence of solicited adverse events between the previous alphavirus vaccine recipients and alphavirus vaccine-naive controls (53·3% vs 40·0%, respectively), although the relatively small sample size of the trial limited the power to detect a significant difference, and there were no reported vaccine-related serious adverse events.

INTERPRETATION:

CHIKV VLP vaccine was well tolerated and similarly immunogenic in both alphavirus vaccine-naive participants and previous recipients of a heterologous alphavirus vaccine. There were no significant differences in adverse events between the groups. The results of this study support the use of CHIKV VLP vaccine in individuals with previous alphavirus vaccine exposure.

Bavarian Nordic confirms buyout talks with private equity firms amid new chikungunya threats

Bavarian Nordic confirmed Thursday that the company is in talks with private equity firms Nordic Capital and Permira about a potential takeover bid for the Danish drugmaker. Just as new outbreaks of chikungunya threaten to become another epidemic, Bavarian Nordic, maker of a vaccine against the mosquito-borne virus, has entered discussions of a potential buyout.Bavarian Nordic confirmed Thursday that the company is in talks with private equity firms Nordic Capital and Permira about a potential takeover bid for the Danish drugmaker.The discussions remain ongoing, and “there can be no certainty” as to whether any offer will be made and its timing, Bavarian said. Such an acquisition would take the Nasdaq Copenhagen-listed company private.The company’s stock price rose more than 21% late Thursday morning. Bavarian Nordic makes Vimkunya, a chikungunya vaccine approved by the U.S. FDA in April for protection among individuals 12 years of age and above. The company in June started a phase 3 trial of the shot in children 2 to 11 years of age, with results expected in the first half of 2028.Revelation of the deal talks emerged just as the World Health Organization (WHO) warned on Tuesday that urgent actions are needed to prevent the escalation of a new wave of chikungunya outbreaks.“We are seeing history repeating itself,” Diana Rojas Alvarez, a medical officer at the WHO and arbovirus team lead with the organization, said during a press briefing, referring to the 2004-05 chikungunya epidemic, as quoted by Reuters.Outbreaks have been spotted in the same Indian Ocean areas that were previously hit, including La Reunion, Mayotte and Mauritius, spreading to Madagascar, Somalia and Kenya. Southeast Asian countries and France have reported alarming transmissions. And China is experiencing the country’s biggest chikungunya outbreak since the virus first emerged in the mainland about two decades ago. Valneva’s Ixchiq, another FDA-approved chikungunya shot, is cleared only in adults. The FDA and the Centers for Disease Control and Prevention recently paused Ixchiq’s use in people 60 years of age and older following reports of some serious adverse events, including two deaths.To expand access to Vimkunya, Bavarian has partnered with Biological E to manufacture and supply the vaccine to endemic low- and middle-income countries.This isn’t the first time Bavarian has found itself at the forefront of a global health crisis. The company has been supplying global governments, including the U.S., with its mpox and smallpox vaccine Jynneos, which played an important countermeasure role during a 2022 mpox outbreak.As of July 9, Bavarian has secured more than 3 billion Danish kroner ($473 million) worth of Jynneos contracts for public preparedness efforts in 2025. In 2024, Bavarian Nordic reported 5.72 billion Danish kroner (about $900 million) in revenue. In the first quarter of 2025, revenue surged 62% to 1.35 billion Danish kroner.As of early May, the company was expecting Vimkunya's full-year revenue to fall between 50 million Danish kroner and 100 million Danish kroner in 2025.Meanwhile, Nordic Capital appears to be in an acquisitive mood, targeting the healthcare industry. The private equity firm recently acquired healthcare data analytics company Arcadia after bowing out of potential buyout talks with biotech platform entity PureTech Health.

Vaccine maker Bavarian Nordic confirms it's in potential takeover talks

Riding a recent wave of wins, Bavarian Nordic confirmed on Thursday that it has “been in discussions” with private equity firms over a potential takeover offer. The Danish vaccine maker said it has been in talks with Nordic Capital and Permira. The conversations are ongoing and there is “no certainty as to whether any offer” will actually be made, Bavarian said in a news release. Timing and terms of a potential offer are also unknown. Spokespersons for Bavarian Nordic, Permira and Nordic Capital all declined to comment. A takeover would come after a string of positive updates from the company. Earlier this month, Bavarian Nordic said it nabbed another smallpox/mpox vaccine supply contract with an undisclosed European country. Last month, it sold a priority review voucher for $160 million thanks to an FDA greenlight for its chikungunya vaccine in February. Bavarian’s market cap was $3 billion on Thursday, following news of the potential takeover. The company has a suite of approved vaccines for smallpox and an mpox vaccine, as well as vaccines for travel health. The company has said it expects little impact from potential pharma tariffs that the US government is mulling. Bavarian Nordic has a commercial site and an R&D manufacturing facility in the US. “We just have to wait and see what concrete things come through, and then we’ll have to respond,” CEO Paul Chaplin told Endpoints News in March. Bavarian said earlier this month that it anticipates total 2025 revenue of DKK 5.7 billion to 6.7 billion DKK (about $899 million to $1.05 billion). Earlier this week, another vaccine company inked a deal. Sanofi said it would pay $1.15 billion upfront for early-stage vaccine maker Vicebio. Permira’s healthcare portfolio includes PharmaCord, Kedrion Biopharma, Neuraxpharm and others. The investment firm has deployed more than €5 billion ($5.8 billion) across more than 20 companies in the sector, according to a June press release . Nordic Capital, meanwhile, was rejected by PureTech Health earlier this year. The firm’s healthcare portfolio includes Advanz Pharma and LEO Pharma, among others.

Bavarian Nordic Receives Acceptance from Health Canada for Review of the New Drug Submission for its Chikungunya Vaccine

COPENHAGEN, Denmark, July 22, 2025 – Bavarian Nordic A/S (OMX: BAVA) announced today that Health Canada has accepted for review the Company’s application for licensure of the single-dose, virus-like particle (VLP) chikungunya vaccine candidate, CHIKV VLP, for immunization to prevent disease caused by chikungunya virus infection in individuals 12 years of age and older. The application screening acceptance by the Directorate confirms that the New Drug Submission is complete and begins a standard review procedure, potentially supporting approval of the vaccine in the first half of 2026. The New Drug Submission is based on the data, which also supported the recent US, EU and UK approvals of the vaccine, including results from two phase 3 clinical trials which enrolled more than 3,500 healthy individuals 12 years of age and older. The studies met their primary endpoints, with results showing that 21 days after vaccination, the vaccine induced neutralizing antibodies in up to 97.8% of the vaccinated individuals, (97.8% in individuals 12 years to 64 and 87.3% in over 65 year olds). The key secondary endpoint of seroresponse rate at day 8 post vaccination was 46.6% and 96.8% at day 15 in the 12-64 year old population and 82.3% at day 15 for the over 65 population. The vaccine was well-tolerated and vaccine-related adverse events were mainly mild or moderate in nature. The most common side effects were pain at the injection site, fatigue, headache, and muscle pain1,2. Paul Chaplin, President and CEO of Bavarian Nordic, said: “The regulatory submission and acceptance by Health Canada represents yet another highlight in our efforts to expand access to our chikungunya vaccine across the globe. Pending approval, this vaccine will further strengthen our offering for Canadians seeking protection against serious diseases when traveling the world.” About CHIKV VLPCHIKV VLP is a vaccine for the prevention of chikungunya disease in individuals aged 12 years and above. It is designed to induce a robust seroresponse, with protective immunity starting to develop as early as 1 week after vaccination. Pending regulatory approval, CHIKV VLP vaccine will be available in a prefilled syringe. CHIKV VLP does not contain viral genetic material and is therefore non-infectious and unable to cause disease, ensuring a broad range of people can benefit from vaccination. The vaccine was approved by the U.S. Food and Drug Administration (FDA) and the European Commission in February 20253,4 and the United Kingdom in May 20255 under the trade name VIMKUNYA®6. About chikungunyaChikungunya is a mosquito-borne disease caused by the chikungunya virus (CHIKV). In the past 20 years, the virus has emerged across several regions in Asia, Africa, and the Americas, including many popular travel destinations, often causing large unpredictable outbreaks. Since its discovery, CHIKV has been identified in more than 110 countries, with evidence of transmission confirmed in more than 50 countries over the past five years7. Chikungunya typically presents with acute symptoms, including fever, rash, fatigue, headache, and often severe and incapacitating joint pain. Most patients recover within 1-2 weeks, but 30-40% of those affected may develop chronic arthritis that can last for months or even years8. In 2024, 620,000 cases of chikungunya and over 200 deaths were reported worldwide9. Recent data suggest that chikungunya is severely underreported and often misdiagnosed as dengue fever due to a similar symptom profile10.
