A Study to Learn About BNT162b2 (LP.8.1)-Adapted Vaccine Against SARS-CoV-2 in Children 5 Through 11 Years of Age That Are Considered at Higher Risk of Severe COVID-19

The purpose of this study is to learn about the safety, tolerability, and immunogenicity of an updated vaccine against COVID-19, called BNT162b2 (2025/2026 formulation). This study is seeking participants 5 through 11 years of age who: * have at least 1 underlying condition that puts them at high risk for severe outcomes from COVID-19, * and are medically stable. All participants in this study will receive 1 vaccine dose given in the muscle of their arm of a BNT162b2 (2025/2026 formulation) vaccine which targets the COVID-19 virus, specifically the strain selected for the 2025-2026 COVID-19 viral respiratory season. Participants will take part in this study for about 6 months and will need to visit the clinical study site at least 2 times.

A Study to Learn About a COVID-19 Vaccine in Healthy Adults 50 Through 64 Years of Age

This study is designed to find out how well the COVID-19 vaccine protects people 50 to 64, who don't have any serious health problems, compared to a group that receives a vaccine that doesn't contain an ingredient to protect against COVID-19 (placebo).

A Study to Learn About COVID-19 RNA-Based Variant-Adapted Vaccine Candidate(s) Against SARS-CoV-2 in Participants Ages 12 Through 64 Years Considered at Higher Risk of Severe COVID-19, and Participants Ages ≥65 Years

The purpose of this study is to learn about the safety, tolerability, and immunogenicity of an updated vaccine against COVID-19. This study is seeking participants 12 through 64 years of age who are considered to be at higher risk for severe COVID-19 disease per study protocol and those 65 years of age and older. All participants in this study will receive 1 shot to their arm of a BNT162b2 (2025/2026 recommended SARS-CoV-2 strain) 30 µg RNA-based vaccine which targets a circulating variant of SARS-CoV-2 and is selected for the 2025-2026 COVID-19 respiratory virus season. This study is about 6 months for each participant. Participants will either be enrolled in Cohort 1 (Groups 1 and 2) or Cohort 2 (Groups 3 and 4). Participants enrolled in Cohort 1 will have at least 4 visits and participants enrolled in Cohort 2 will have at least 3 visits.

Influenza & COVID-19 Obstetric and Perinatal Epidemiology Study in India

This study will be conducted as a prospective cohort study, enrolling all eligible women in their first trimester of pregnancy during a baseline visit during week 6-13 of pregnancy at Government Medical College Hospital, Nagpur. The Hospital provides primary, secondary, and tertiary care and the obstetric department delivers about 10,000 babies a year. The hypothesis is that co-infection of other respiratory viruses (ORV), particularly COVID-19 and Influenza increases the risk of adverse pregnancy outcomes in mothers and babies and could address the current standard of care in India to not vaccinate pregnant women during pregnancy, by either encouraging vaccination against both viruses before planning a pregnancy or during pregnancy based on global data supporting the safety of this strategy.
