This is a Phase 1/2/3 study in healthy children. Dependent upon safety and/or immunogenicity data generated during the course of this study, and the resulting assessment of benefit-risk, the safety, tolerability, and immunogenicity of BNT162b2 in participants \<6 months of age may subsequently be evaluated.

This phase II trial studies how well TPIV100 and sargramostim work in treating patients with HER2 positive, stage II-III breast cancer that has residual disease after chemotherapy prior to surgery. It also studies why some HER2 positive breast cancer patients respond better to chemotherapy in combination with trastuzumab and pertuzumab. TPIV100 is a type of vaccine made from HER2 peptide that may help the body build an effective immune response to kill tumor cells that express HER2. Sargramostim increases the number of white blood cells in the body following chemotherapy for certain types of cancer and is used to alert the immune system. It is not yet known if TPIV100 and sargramostim will work better in treating patients with HER2 positive, stage II-III breast cancer. Read Less

The primary objective of this study was to describe the safety profile of Meningococcal Polysaccharide (Serogroups A, C, Y, and W) Tetanus Toxoid (MenACYW) Conjugate Vaccine and Meningococcal (Groups A, C, Y and W 135) Oligosaccharide Diphtheria CRM197 (MENVEO®) Conjugate Vaccine when administered concomitantly with routine pediatric vaccines in healthy infants and toddlers.

This study evaluates whether it is safe to administer a helper peptide vaccine with BRAF inhibitor and MEK inhibitor therapy. This study will also evaluate the effects of the combination of the peptide vaccine and BRAF inhibitors/MEK inhibitors on the immune system. We will monitor these effects by performing tests in the laboratory on participants' blood and tumor samples. Read Less

Background: Allergic reactions have been reported to occur after vaccination with both the Pfizer-BioNTech COVID-19 Vaccine and Moderna COVID-19 Vaccine. Allergic reactions range from mild to severe and include life- threatening anaphylactic reactions, although no deaths have been reported with either vaccine. This study is designed with two principal aims: * To estimate the proportions of systemic allergic reactions to the Pfizer-BioNTech COVID-19 Vaccine and the Moderna COVID-19 Vaccine in a High-Allergy/Mast Cell Disorder (HA/MCD) population, and * If the risk in the HA/MCD is demonstrable, to determine whether the proportions are higher in the HA/MCD in comparison to a representative population without severe allergies or mast cell disorders Read Less

Primary Objective: To demonstrate sufficiency of the vaccine seroresponse to meningococcal serogroups A, C, W, and Y following administration of a single dose of Meningococcal Polysaccharide (Serogroups A, C, Y, and W 135) Tetanus Toxoid (MenACYW) Conjugate vaccine to Group 1 participants (who received primary vaccination with Menomune vaccine greater than or equal to \[\>= 3\] years earlier at \>= 56 years of age in Study MET49). Secondary Objectives: Secondary Objective 1 - To demonstrate sufficiency of the vaccine seroresponse to meningococcal serogroups A, C, W, and Y following administration of a single dose of MenACYW Conjugate vaccine to Group 2 participants (who received primary vaccination with MenACYW Conjugate vaccine \>= 3 years earlier at \>= 56 years of age in Study MET49). Secondary Objective 2 - To describe vaccine seroresponse rates with respect to serogroups A, C, W, and Y in serum specimens collected 6 days (window, 5-7) post-vaccination in approximately 60 participants from Group 1 (Menomune-primed) and approximately 60 participants from Group 2 (MenACYW Conjugate vaccine-primed). Secondary Objective 3 - To describe antibody persistence \>= 3 years after primary vaccination with Menomune vaccine or MenACYW Conjugate vaccine for participants from all groups. Read Less

A total of 18,000 eligible subjects (or 6,000 subject distributed evenly between the 3 study arms) will be enrolled. Eligible subjects will be randomized in 1:1:1 (cell-culture-based vaccine, the recombinant vaccine, or the egg-based vaccine) over four influenza seasons (2018-2019, 2019-2020, 2020-2021, and 2021-2022).

The aim of this study was to evaluate the immune response and safety of both GlaxoSmithKline Biologicals SA's (GSK's) herpes zoster (HZ) subunit (su) vaccine in healthy adults 50 years of age (YOA) and older and quadrivalent seasonal influenza (Flu D-QIV) vaccine in healthy adults 18 YOA and older, when administered sequentially or co-administered with Moderna's mRNA-1273 booster vaccination against COVID-19.

Primary Objective: To demonstrate the vaccine seroresponse sufficiency of meningococcal serogroups A, C, Y, and W following the administration of a booster dose of meningococcal Polysaccharide (Serogroups A, C, Y and W) Tetanus Toxoid (MenACYW) Conjugate vaccine: * In Group 1 participants who were first vaccinated with 1 dose of MenACYW Conjugate vaccine 3-6 years before the booster dose. * In Group 2 participants who were first vaccinated with 1 dose of Menveo vaccine (meningococcal \[Groups A, C, Y and W135\] Oligosaccharide Diphtheria CRM197 Conjugate vaccine) 3-6 years before the booster dose. Secondary Objective: To describe: * The vaccine seroresponse, seroprotection (serum bactericidal assay using human complement \[hSBA\] titer greater than or equal to \[\>=\]1:8), and antibody responses (geometric mean titers \[GMTs\]) of meningococcal serogroups A, C, Y, and W measured using hSBA in serum specimens collected 6 days (±1 day) after vaccination in a subset of 50 participants per group (Groups 1 and 2). * The vaccine seroresponse, seroprotection (hSBA titer \>=1:8), and antibody responses (GMTs) to serogroups A, C, Y, and W measured using hSBA on Day (D)0 (pre-vaccination) and D30 (+14 days) after vaccination with MenACYW Conjugate vaccine alone (Groups 1 and 2). * The antibody persistence (GMTs and vaccine seroprotection; hSBA titer \>=1:8) of meningococcal serogroups A, C, Y, and W before a booster dose in participants who received either MenACYW Conjugate vaccine or Menveo vaccine 3-6 years earlier. * The antibody persistence (GMTs and vaccine seroprotection; hSBA titer \>=1:8) of meningococcal serogroups A, C, Y, and W in participants who received either a single dose MenACYW Conjugate vaccine (participants randomized to MET59 Groups 1, 3, and 4) or Menveo vaccine (participants assigned to MET59 Group 2), as part of study MET50, or MET43 (participants randomized to MET59 Groups 1, 3 and 4). * To describe the vaccine seroresponse, seroprotection (hSBA titer \>=1:8), and antibody responses (GMTs) to the antigens present in MenACYW Conjugate vaccine, when MenACYW Conjugate vaccine was given concomitantly with meningococcal serogroup B (MenB) vaccine (Groups 3 and 4), compared to those when it was given alone (Group 1).

This Phase 3 study was intended to assess the relative efficacy of the Quadrivalent VLP Influenza Vaccine during the 2018-2019 influenza season compared to a licensed vaccine in elderly adults 65 years of age and older. One dose of VLP Influenza Vaccine (30 μg/strain) or of Comparator (15 μg/strain) was to be administered to 12,738 participants. Read Less
