Huh7, HeLa and 293T cells were maintained in DMEM (Invitrogen) with 10% FCS and 0.1 mM non-essential amino acids. NIH-3T12 cells were grown in DMEM supplemented with 5% FCS, 100 U penicillin per ml, 100 μg streptomycin per ml and 2 mM L-glutamine. STAT1−/− fibroblasts (an SV40 large T antigen immortalized human skin fibroblast line) were grown in RPMI (Invitrogen) with 10% FCS. The construction, characterization and generation of viral stocks for the following viruses have been previously described: CVB-GFP (derived from infectious clone pMKS1-GFP)24 (link), PV-GFP (strain P1M, derived from infectious clone pPVM-2A144-GFP)25 (link), EAV-GFP (derived from infectious clone pEAV211-GFP2aT)26 (link), SINV-A-GFP and SINV-G-GFP (derived from infectious clones pS300-GFP and pG100-GFP)27 (link), ONNV-GFP (derived from infectious clone pONNV.GFP)28 (link), VEEV-GFP (derived from pTC83-GFP infectious clone)4 (link), FLUAV-GFP (based on strain PR8)29 (link), PIV3-GFP (based on strain JS)30 (link), NDV-GFP (based on strain Hitchner B1)31 (link), HMPV-GFP32 (link) (based on isolate CAN97-83), RSV-GFP (based on strain A2)32 (link), MV-GFP (MVvac2-GFP, based on vaccine strain, Edmonston lineage measles virus)33 (link) and BUNV-GFP34 (link) (based on rBUN-del7GFP).

For immunizing infections such as those due to CHIKV, age-stratified serological surveys can be used to infer the history of circulation in the community [10 (link)]. In such situations, the age of individuals is an indicator of the cumulative time of potential infection risk. Assuming that the risk of infection is age independent, we used a likelihood framework to estimate the annual probability of infection in the population (ie, the proportion of the susceptible population infected per year) for each year between 1952 and 2012. A similar approach has been used to characterize the transmission of measles virus, dengue virus, and other pathogens [10 (link)–12 (link)]. We could not reliably estimate the annual probability of infection before 1952, as there were insufficient individuals in our data set who were alive at the time. Therefore, we assumed a constant probability of infection between 1932 and 1952 and that all individuals were susceptible before 1932. Each individual contributed to estimates of the probability of infection for the years between their birth and the serosurvey. We fit the model in a Bayesian Markov chain Monte Carlo framework, using the RStan package in R [13 ]. Further details of the model can be found in the Supplementary Materials (Text 1).
We compared a model with different annual probabilities of infection (ie, outbreaks lasting 1 year) to models where outbreaks lasted for 2, 3, 4, and 5 years and where the hazard of infection over the entire analyzed period was constant. We defined an outbreak as an event in which at least 1% of the susceptible population was infected over the outbreak period. The total number of outbreaks per model iteration was therefore the total number of periods with an estimated probability of infection of >1%. The deviance information criterion (DIC) was used to compare model fit. DIC differences of <3 as compared to the best model were considered good support for that model, whereas DIC differences of >5 were considered weak support [14 ].

We have used TCID50 titration method as a reference for the validation of our rapid titration technique. TCID50 is based on the end-point dilution of the virus at which a cytopathic effect (CPE) is detected in 50% of the cell culture replicates infected by a given amount of virus suspension [2] . The latter was serially diluted in 0.25 ml of DMEM medium supplemented with 6% fetal calf serum (FCS) and antibiotics (culture medium) by serial transfer of 0.027 ml (i.e. ten-fold dilution) in the first row of a 96 well plate. When diluting the virus suspension, each micropipette tip ought to be changed at every dilution to avoid uneven distribution of infectious particles that remain adsorbed on the tip. Subsequently, 0.030 ml of each dilution was distributed vertically, i.e. 8 replicates for each dilution. Permissive cells, i.e. Vero cells, (10,000 cells in 0.2 ml) were seeded in each well, and incubated at 37°C in 5% C02 and humid atmosphere. CPE induced by measles virus could be observed under the microscope after 3–4 days, but because CPE located in the well edge could hardly be spotted, the final counting of wells with CPE was done after 10 days. This incubation time can be much shorter for quicker growing viruses (i.e. 1–2 days for VSV). To avoid underestimation of virus titer, the incubation time should be adapted to the virus species and physicochemical conditions used for virus propagation. TCID50 was then calculated using the formula: where “Above 50%” dilution is the last dilution expressed as the denominator of 1 (i.e. 250 for 1/250 dilution) for which ≥50% wells display CPE, (“Above 50%” and “Below 50%” values are fraction of wells with CPE at the last dilution for which ≥50% wells display CPE and fraction of wells with CPE at the next dilution, respectively, and v the virus volume (in ml) from the undiluted sample used to inoculate the wells.

Phocine distemper virus is closely related to the canine distemper virus in the Paramyxoviridae family; both pathogens are in the same genus as measles virus [35 (link)]. An outbreak of phocine distemper in 2002 was detected in the North Sea population of harbor seals. First detected on Anhholt Island in Denmark in May, the virus spread into the Netherlands with the first detection on June 16, presumably by the highly mobile gray seals who share haul-outs with harbor seals [36 (link)]. The 2002 outbreak cost an estimated 30,000 harbor seals their lives, making this the largest recorded mass mortality event ever in marine mammals [36 (link)].
Data on seal stranding events were obtained from [37 (link)] and [38 ], who used a public database, waarneming.nl, that contained weekly stranding data collected by seal rescue centers in the region. Stranding events may or may not be lethal, though rescued individuals are removed from the population and brought to local seal rescue centers. We used WebPlotDigitizer software [39 ] to acquire data from published figures from [37 (link)] and [38 ], rounding all digitized values to the nearest integer value. The Dutch outbreak ended by December the same year as indicated by the return of stranding rates to pre-epidemic levels [37 (link)], which resulted in 25 weeks of stranding data. We also obtained annual harbor seal strandings from [38 ] for the three years before the 2002 outbreak (1999–2001) and the three years following the outbreak (2003–2005) to determine the average weekly stranding rates in the absence of the phocine distemper outbreak. We limited our study to these years because the harbor seal population was relatively constant over that period of time [38 ].

Briefly, infected HEK-293 cells stably expressing One-STrEP-tagged RIG-I or Cherry protein were lysed with MOPS lysis buffer (20 mM MOPS-KOH pH7.4, 120 mM of KCl, 0.5% Igepal, 2 mM ß-Mercaptoethanol), supplemented with 200 U/mL RNasin (Promega) and Complete Protease Inhibitor Cocktail (Roche). An aliquot of each cell lysate was used to perform total RNA purification using TRI Reagent LS (Sigma). The remaining cell lysate was kept to purify the RIG-I/RNA, or Cherry/RNA complexes by affinity chromatography using StrepTactin Sepharose High Performance beads (GE Healthcare). RNAs that had co-precipitated with either RIG-I or Cherry protein were isolated using TRI Reagent LS. RNA was dissolved in DNase-free and RNase-free ultrapure water. Extracted RNAs were analyzed using the Nanovue (GE Healthcare) and Bioanalyser RNA Nano kit (Agilent). 300 ng of each RNA sample was treated for library preparation using the TruSeq Stranded mRNA Sample Preparation kit (Illumina). Sequencing was performed on the Illumina Hiseq2000 platform to generate single-end 51 bp reads bearing strand specificity [28 (link)]. Three biological experiments were performed.
For the analysis of total and RIG-I/Cherry-specific RNAseq, reads were aligned against Human Genome Reference (GRCh37) with Bowtie2 v2.3.5.1 [48 (link)]. Reads without a positive match against GRCh37, were aligned against the Measles reference genome (NC_001498). Resulting SAM files were analyzed with Samtools v1.13 [49 (link)]. The statistical analyses were performed with SHAMAN (shaman.pasteur.fr) [50 (link)]. The count of reads aligned against Human genome chromosomes and Measles virus were normalized by using the weighted non-null normalization method described in [50 (link)]. Resulting P values were adjusted according to the Benjamini and Hochberg procedure.

HIV-infected persons on antiretroviral therapy (ART) were recruited from the Erlangen HIV cohort at the Universitätsklinikum in Erlangen. HIV-uninfected persons were recruited through the Institute of Clinical and Molecular Virology of the Universitätsklinikum in Erlangen. For the comparison of the recall TT responses between HIV-infected and HIV-uninfected groups, individuals with self-reported prior vaccination were recruited. These were 14 HIV-uninfected persons with a median age of 49 years (interquartile range (IQR) 44–54) and 33 HIV-infected persons with a median age of 51 years (IQR 40–54) and a median CD4 T cell count of 647 cells/mm3 (IQR 538–794). To assess the effect of anti-PD-1 and anti-PD-L1 antibodies on the recall IFNγ responses of HIV-infected persons on ART, lymphocytes of 30 HIV-infected TT-seropositive and 29 HIV-infected measles virus (MV)-seropositive subjects were probed. Detailed characteristics of the 30 TT- and 29 MV-seropositive participants are presented in Table 1.
The study was approved by the ethics committees of the Universitätsklinikum Erlangen (numbers 235-18B and 250-15B) and carried out in compliance with institutional guidelines. All participants gave written informed consent.

For a comparison of the recall IFNγ responses to TT between HIV-infected and HIV-uninfected persons, cryopreserved PBMCs were thawed, washed in R10 medium and rested for 6 h at 37 °C. Following the seeding of 1 × 106 cells per well, PBMCs in R10 were either left untreated or stimulated with TT protein (Tetanol, GSK—0.5 I.E) and incubated at 37 °C in 5% CO2 for 3 days. To assess the effect of anti-PD-1 and anti-PD-L1 on recall IFNγ responses, cryopreserved PBMCs were thawed, washed in R10 medium and rested overnight at 37 °C. Cells were washed, seeded in 96-well round bottom plates at 0.9 × 106 cells per well in R10 medium and incubated for 6 h with 20 µg/mL or 40 µg/mL anti-PD-1 (Nivolumab), anti-PD-L1 (Durvalumab), or their respective IgG4 and IgG1 isotype controls (BioXCell). Next, TT protein (Tetanol, GSK—0.5 I.E) or an MV 20-mer overlapping peptide pool corresponding to the measles virus hemagglutinin and fusion proteins (EMC, 10 µg/mL) was added per well. As a positive control, PBMCs were stimulated with Staphylococcal enterotoxin B (SEB, Sigma, 0.25 µg/mL final concentration). As negative controls, PBMCs were either unstimulated (TT control) or supplemented with DMSO (MV peptide pool control). Following the addition of all stimuli, cells were incubated at 37 °C in 5% CO2 for 3 days. All cell culture supernatants were collected after 3 days of stimulation for the measurement of IFNγ concentrations using the human IFNγ Duoset (R&D) as per the manufacturer’s recommendation. Measurement of IFNγ concentrations was performed in duplicate and the average of the duplicates was reported.

The dCoV vaccine strain was titrated using a standard plaque assay. Briefly, a Vero cell monolayer was prepared in 6-well plates one day prior to virus titration. A ten-fold serial dilution of the samples were prepared in Dulbecco’s Minimum Essential Medium (DMEM) containing 2% fetal bovine serum (FBS). The cell monolayer was washed once with DMEM and infected with serially diluted samples. After 1 h of incubation at 37 °C, 4.0 mL of overlay medium (1.25% carboxymethyl cellulose in DMEM containing 2% FBS) was added on the top of inoculums and further incubated at 37 °C undisturbed. After 3 days, the cells were washed with phosphate-buffered saline (PBS) and the plaques were visualized via negative staining with 0.3% crystal violet in 5% formalin. Excess stain was washed off using water. Distinctly countable plaques (between 20 to 120 plaques per well) were counted and the virus titer was calculated per the method described by Darling et al., 1998. Virus titers were expressed as Log10 plaque-forming units per 0.5 mL (Log10 PFU/0.5 mL) or per dose as applicable.
Measles and rubella viruses were titrated using the standard CCID50 assay. Measles virus was titrated using Vero cells plated on the day of test while rubella virus was titrated in RK-13 cells plated one day prior to test in 96-well plates. After infection with 10-fold serially diluted samples, the 96-well plates were incubated and observed microscopically on day 7 through day 10 post-infection for the cytopathic effect (CPE) indicating the presence of virus. The 50% end point was calculated using the Spearman and Karber method and the titers were represented as Log10 CCID50/dose.
