INFLUENZA, HUMAN

This study tested new modified RNA (modRNA) flu vaccines in 1,202 healthy adults aged 18 and older. The goal was to see if the vaccines are safe and how well they trigger the body's immune defenses. Participants received either a modRNA vaccine or an approved flu shot, and were f…

This study tested whether giving a combined COVID-19 and flu vaccine as one shot is safe and helps the body build defenses against both viruses. It involved 644 healthy adults aged 50 and older. Researchers measured side effects and antibody levels to see how well the combo worke…

This study tested a booster vaccine for H5N6 bird flu in about 260 adults. Some had received a related H5N1 vaccine before, while others had not. The goal was to see if one or two booster shots were safe and could boost the body's immune defenses against the virus.

This early-stage study tested a new mRNA-based flu vaccine in 324 healthy younger and older adults. The main goal was to see if the vaccine is safe and to measure the immune response it triggers. Researchers monitored side effects like pain, fever, and fatigue, and checked antibo…

This early-stage study tested a new type of seasonal flu vaccine called ARCT-2138, which uses self-amplifying mRNA technology to potentially boost immune responses. Researchers gave the vaccine to 139 healthy adults aged 18-49 and 65-85 to check for side effects and measure antib…

This early-stage study tested a new type of flu vaccine called a self-amplifying RNA (saRNA) vaccine in 440 healthy adults aged 18 to 49. The goal was to see if the vaccine is safe and how the body responds to it. Participants received either the saRNA vaccine, a licensed flu sho…

This study tested an experimental mRNA vaccine designed to protect against a potential pandemic caused by the H5 bird flu virus. Nearly 1,000 healthy adults aged 18 to 85 received the vaccine to check for side effects and measure immune responses. The goal was to find the best do…

This study tested a new quadrivalent influenza vaccine (protecting against four flu strains) in over 1,300 healthy infants and children aged 6 to 35 months. The goal was to see if the vaccine triggers a strong immune response and is safe compared to existing flu vaccines. Results…

This study tested a new mRNA-based flu vaccine in 845 healthy adults aged 18 to 85. The goal was to find the best dose and check how well it triggers an immune response and how safe it is. The vaccine uses mRNA technology, similar to some COVID-19 vaccines, to teach the body to f…

This study tested a new self-amplifying mRNA vaccine (ARCT-2304) designed to protect against a future pandemic flu. 212 healthy adults aged 18-80 received either the experimental vaccine or a licensed flu shot. Researchers monitored side effects and measured immune responses to f…

This study tested different types of flu vaccines in over 1,800 adults aged 65-82 in Hong Kong to see which one provides the strongest and longest immune response. Participants received either a standard flu shot or a more potent vaccine (high-dose, adjuvanted, or recombinant) ea…

This study looked at how the immune system responds to getting the flu vaccine year after year. Researchers followed nearly 1,000 healthy adults aged 18-45 in Hong Kong who had not been vaccinated in the past two years. They measured antibody levels and immune cell responses to u…
