Circular RNA Vaccines against SARS-CoV-2 and Emerging Variants
Open accessAbstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its emerging variants of concern (VOC), such as Delta (B.1.617.2) and Omicron (B.1.1.529), has continued to drive the worldwide pandemic. Therefore, there is a high demand for vaccines with enhanced efficacy, high thermostability, superior design flexibility, and fast manufacturing speed. Here, we report a circular RNA (circRNA) vaccine that encodes the trimeric RBD of SARS-CoV-2 Spike protein. Without the need of nucleotide modification, 5’-capping or 3’-polyadenylation, circRNA could be rapidly produced via in vitro transcription and is highly thermostable whether stored in naked or lipid-nanoparticle (LNP)-encapsulated format. LNP-encapsulated circRNA RBD elicited potent neutralizing antibodies and T cell responses, providing robust protection against Beta (B.1.351) and native viruses in mice and rhesus macaques, respectively. Notably, circRNA vaccine enabled higher and more durable antigen production than 1mΨ-modified mRNA vaccine, eliciting a higher proportion of neutralizing antibodies and stronger Th1-biased immune responses. Importantly, we found that circRNA RBD-Omicron vaccine induced effective neutralizing antibodies against only Omicron but not Delta variant. By contrast, circRNA RBD-Delta could elicit high level of neutralizing antibodies against both Delta and Omicron. Following two doses of either native- or Delta-specific vaccination, circRNA RBD-Delta , but not Omicron or Beta vaccines, could effectively boost the neutralizing antibodies against both Delta and Omicron variants. These results suggest that circRNA RBD-Delta is a favorable choice for vaccination to provide a broad-spectrum protection against the current variants of concern of SARS-CoV-2.

TL;DR
A circular RNA vaccine expressing trimeric SARS-CoV-2 RBD elicited neutralizing antibodies and T cell responses in mice and rhesus macaques, with higher and more durable antigen expression than 1mΨ-modified mRNA. The circRNARBD-Delta vaccine showed broad neutralization against Delta and Omicron and was an effective booster, whereas the Omicron-specific vaccine neutralized Omicron but not Delta.
Key findings
- LNP-circRNARBD induced RBD-specific IgG endpoint GMTs of ∼1.9 × 10⁴ (10 μg) and ∼5.7 × 10⁵ (50 μg) in mice, with pseudovirus NT50 ∼4.5 × 10³ and authentic SARS-CoV-2 NT50 ∼7.0 × 10⁴.
- circRNARBD-Delta elicited an NT50 of ∼1.4 × 10⁵ against Delta pseudovirus at 10 μg and maintained Omicron neutralization with NT50 ∼4.7 × 10³; as a third booster after two-dose circRNARBD, it raised Omicron geometric mean NT50 from ∼4 × 10² to ∼3.2 × 10⁴.
- circRNARBD-Omicron induced Omicron-specific IgG GMTs of ∼4.7 × 10⁴ (5 μg) and ∼2.2 × 10⁵ (10 μg), with Omicron NT50s of ∼2.5 × 10³ and ∼8.6 × 10³, but neutralizing activity was hardly detected against native strain or Delta.
- In rhesus macaques, circRNARBD IgG GMTs were ∼2.1 × 10⁴ (20 μg), ∼1.6 × 10⁴ (100 μg), and ∼7 × 10³ (500 μg); authentic virus NT50s were ∼80, ∼120, and ∼50, respectively. Vaccinated macaques showed nearly 1,000-fold reduced lung genomic RNA at 100/500 μg and nearly no detectable subgenomic RNA at all doses, with no severe clinical adverse effects.
Methods
- circRNA vaccines encoded trimeric SARS-CoV-2 RBD with a human tPA signal peptide and T4 fibritin foldon, produced by group I intron autocatalysis or T4 RNA ligase, and encapsulated in LNPs; comparisons used 1mΨ-modified and unmodified mRNA encoding the same RBD sequence.
- Female BALB/c mice (6–8 weeks) were immunized intramuscularly with varying circRNA doses; 2–4-year-old male rhesus macaques received 20, 100, or 500 μg circRNARBD, circRNACtrl, or PBS on days 0 and 21. Mice were challenged with Beta variant; macaques were challenged with native SARS-CoV-2.
- Analyses included ELISA endpoint GMTs, pseudovirus and authentic virus NT50 assays, RT-qPCR viral loads, ELISpot and flow cytometry for T cell cytokines, histopathology, and unpaired or paired two-sided Student’s t tests.
Limitations
- Stated by the paper: small rhesus macaque numbers caused high variation and large error bars; immunogenicity of IVT-produced circRNAs remains a potential concern; safety awaits further NHP and clinical trials; the mRNA comparator encoded trimeric RBD and differed from mRNA-1273 and BNT162b2, which encode full-length spike and use different manufacturing processes.
- Evident from the text: no human clinical data are reported; protection against Omicron and Delta was assessed mainly by neutralization assays, while mouse challenge used Beta and macaque challenge used native SARS-CoV-2.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
