V114 (15-valent pneumococcal conjugate vaccine [PCV]) contains all serotypes in 13-valent PCV (PCV13) and additional serotypes 22F and 33F. This study evaluated safety and immunogenicity of V114 compared with PCV13 in healthy infants, and concomitant administration with DTPa–HBV–IPV/Hib and rotavirus RV1 vaccines. V114 and PCV13 were administered in a 2+1 schedule at 2, 4, and 11–15 months of age. Adverse events (AEs) were collected on Days 1–14 following each vaccination. Serotype-specific anti-pneumococcal immunoglobulin G (IgG) was measured 30 days post-primary series (PPS), immediately prior to a toddler dose, and 30 days post-toddler dose (PTD). Primary objectives included non-inferiority of V114 to PCV13 for 13 shared serotypes and superiority of V114 to PCV13 for the two additional serotypes. 1184 healthy infants 42–90 days of age were randomized 1:1 to V114 (n = 591) or PCV13 (n = 593). Proportions of participants with solicited AEs and serious AEs were comparable between vaccination groups. V114 met pre-specified non-inferiority criteria for all 13 shared serotypes, based on the difference in proportions of participants with serotype-specific IgG concentrations ≥0.35 μg/mL (response rate; lower bound of two-sided 95% confidence interval [CI] >−10.0) and IgG geometric mean concentration (GMC) ratios (lower bound of two-sided 95% CI >0.5), and pre-specified superiority criteria for serotypes 22F and 33F (lower bound of two-sided 95% CI >10.0 for response rates and >2.0 for GMC ratios). Antibody responses to DTPa–HBV–IPV/Hib and RV1 vaccines met pre-specified non-inferiority criteria, based on antigen-specific response rates to DTPa–HBV–IPV/Hib and anti-rotavirus IgA geometric mean titers. After a 2+1 schedule, V114 elicited non-inferior immune responses to 13 shared serotypes and superior responses to the two additional serotypes compared with PCV13, with comparable safety profile. These results support the routine use of V114 in infants. Trial registration: ClinicalTrials.gov: NCT04031846; EudraCT: 2018-003787-31

► The 32-year safety profile of M–M–R™II is described using data from postmarketing surveillance. ► Of ∼575 million doses distributed, 17,536 AEs were voluntarily reported (30.5 AEs/1×106 doses). ► This review provides evidence that the vaccine is safe and well-tolerated. M–M–R™II (measles, mumps, and rubella virus vaccine live; Merck, Sharp, & Dohme Corp.) is indicated for simultaneous vaccination against measles, mumps, and rubella in individuals ≥12 months of age. Before the vaccine era, these viruses infected most exposed individuals, with subsequent morbidity and mortality. One of the greatest achievements of public health has been to eliminate these 3 diseases in large geographic areas. The safety profile of M–M–R™II is described using data from routine global postmarketing surveillance. Postmarketing surveillance has limitations (including incomplete reporting of case data), but allows collection of real-world information on large numbers of individuals, who may have concurrent medical problems excluding them from clinical trials. It can also identify rare adverse experiences (AEs). Over its 32-year history, ∼575 million doses of M–M–R™II have been distributed worldwide, with 17,536 AEs voluntarily reported for an overall rate of 30.5 AEs/1,000,000 doses distributed. This review provides evidence that the vaccine is safe and well-tolerated.

•M-M-R®II manufactured using either rHA or HSA was administered to healthy children 12–18 months and 3–4 years of age.•M-M-R®II manufactured using rHA was well-tolerated and was as immunogenic as M-M-R®II manufactured using HSA.•rHA is an acceptable replacement for HSA in the manufacture of M-M-R®II. Prior to 2006, M-M-R®II (measles, mumps, and rubella virus vaccine live) was manufactured using human serum albumin (HSA) and each dose of the vaccine contained a relatively small amount (≤0.3mg) of HSA. Because of specific regulatory requirements and limited suppliers of HSA acceptable for human use, there was a need to replace HSA with recombinant human albumin (rHA) to mitigate any potential risk to the availability of M-M-R®II. Two different formulations of M-M-R®II manufactured using either rHA or HSA were clinically evaluated for safety and immunogenicity when administered as a 2-dose regimen to healthy children 12–18 months and 3–4 years of age. Adverse events, including those indicative of a possible hypersensitivity reaction, were collected for 42 days after each dose. Antibodies to measles, mumps, and rubella were measured before and approximately 6 weeks after dose 1. Antibodies to rHA were measured before and approximately 6 weeks after dose 1 and dose 2. Antibody seroconversion rates to measles, mumps, and rubella were 97.0%, 99.5%, and 99.7%, respectively, for recipients of M-M-R®II with rHA and 97.2%, 97.9%, and 99.6%, respectively, for recipients of M-M-R®II with HSA, and geometric mean titers to all 3 vaccine viral antigens were comparable between the 2 vaccination groups. The proportions of subjects who reported adverse events, including those suggestive of hypersensitivity reactions, after each dose of study vaccine were comparable between the 2 vaccination groups. No subject had detectable antibodies to rHA immediately prior to or following receipt of either the first or second dose of study vaccine. Given the comparable immunogenicity and safety profiles of both formulations, rHA is an acceptable replacement for HSA in the manufacture of M-M-R®II.

The dissection of complex traits of economic importance to the pig industry requires the availability of a significant number of genetic markers, such as single nucleotide polymorphisms (SNPs). This study was conducted to discover several hundreds of thousands of porcine SNPs using next generation sequencing technologies and use these SNPs, as well as others from different public sources, to design a high-density SNP genotyping assay. A total of 19 reduced representation libraries derived from four swine breeds (Duroc, Landrace, Large White, Pietrain) and a Wild Boar population and three restriction enzymes (AluI, HaeIII and MspI) were sequenced using Illumina's Genome Analyzer (GA). The SNP discovery effort resulted in the de novo identification of over 372K SNPs. More than 549K SNPs were used to design the Illumina Porcine 60K+SNP iSelect Beadchip, now commercially available as the PorcineSNP60. A total of 64,232 SNPs were included on the Beadchip. Results from genotyping the 158 individuals used for sequencing showed a high overall SNP call rate (97.5%). Of the 62,621 loci that could be reliably scored, 58,994 were polymorphic yielding a SNP conversion success rate of 94%. The average minor allele frequency (MAF) for all scorable SNPs was 0.274. Overall, the results of this study indicate the utility of using next generation sequencing technologies to identify large numbers of reliable SNPs. In addition, the validation of the PorcineSNP60 Beadchip demonstrated that the assay is an excellent tool that will likely be used in a variety of future studies in pigs.

The ( )-like gene family encodes key regulators of flower induction that affect the timing of reproduction in many angiosperm species. Agricultural research has therefore focused on such genes to improve the success of breeding programs and enhance agronomic traits. We recently identified a novel -like gene ( ) that encodes a day-neutral floral activator in the model tobacco crop . However, further characterization is necessary to determine its value as a target for breeding programs. We therefore investigated the function of NtFT5 by expression analysis and mutagenesis. Expression analysis revealed that is transcribed in phloem companion cells, as is typical for -like genes. However, high levels of mRNA accumulated not only in the leaves but also in the stem. Loss-of-function mutants (generated using CRISPR/Cas9) were unable to switch to reproductive growth under long-day conditions, indicating that NtFT5 is an indispensable major floral activator during long-days. Backcrossing was achieved by grafting the mutant scions onto wild-type rootstock, allowing the restoration of flowering and pollination by a wild-type donor. The resulting heterozygous / plants flowered with a mean delay of only ~2 days, demonstrating that one functional allele is sufficient for near-normal reproductive timing. However, this minor extension of the vegetative growth phase also conferred beneficial agronomic traits, including a >10% increase in vegetative leaf biomass on the main shoot and the production of more seeds. The agronomic benefits of the heterozygous plants persisted under various abiotic stress conditions, confirming that is a promising target for crop improvement to address the effects of climate change.
