This study tested an experimental Zika vaccine (mRNA-1893) in 808 healthy adults aged 18 to 65. The goal was to check if the vaccine is safe and triggers a strong immune response. Participants received either the vaccine or a placebo, and researchers monitored side effects and an…

This study tested a single shot that aims to protect against both COVID-19 and the flu. About 932 adults aged 50 to 64 received the experimental mRNA-1083 vaccine. Researchers checked for side effects and measured antibody levels one month after vaccination to see how well the va…

This large study tested an experimental mRNA flu vaccine (mRNA-1010) against a standard flu shot in over 40,000 adults aged 50 and older. The goal was to see if the mRNA vaccine is safer and works better at preventing flu illness. Results will help determine if this new type of f…

This study tested a new mRNA-based flu vaccine (mRNA-1010) in 172 healthy adults aged 18-50 and 65-80. The goal was to check its safety and how well it triggers the immune system compared to standard flu vaccines. Results help determine if the vaccine is safe and effective enough…

This study tested a new COVID-19 vaccine (mRNA-1283) to see if it works as well as the current vaccine (mRNA-1273) in preventing COVID-19. Over 13,500 people aged 12 and older took part. The goal was to compare safety, immune response, and how well each vaccine prevents illness.

This study tested a new combination vaccine called mRNA-1083 that aims to protect against both COVID-19 and the flu with a single shot. It involved 2,457 healthy adults aged 50 and older in Japan, Taiwan, and South Korea. The main goals were to check how well the vaccine triggers…

This study tested an experimental mRNA vaccine (mRNA-1647) for cytomegalovirus (CMV) in 315 healthy adults aged 18-40. The goal was to check safety and see how well the vaccine triggers the immune system to produce antibodies against CMV. Participants received one of three doses …

This study looked at how long the mRNA-1647 vaccine protects against CMV infection in adults. It included 135 people who had already received the vaccine in an earlier study. Some participants also received a booster dose to see if it improves immunity and remains safe.

This study tested an experimental mRNA vaccine (mRNA-1647) for cytomegalovirus (CMV) in healthy teens (9–15 years) and young women (16–25 years). The goal was to see if the vaccine is safe and triggers a strong immune response. Participants received either the vaccine or a placeb…

This study tested an experimental mRNA vaccine (mRNA-1345) against RSV in 360 pregnant women. The goal was to see if the vaccine is safe for mothers and their babies, and whether it can boost antibodies that pass to the infant, potentially protecting them from severe RSV after bi…

This study tested a new mRNA vaccine that targets both flu and COVID-19 in one shot. About 1,758 healthy adults took part to see if the vaccine is safe and triggers a strong immune response. The goal was to find the best dose and formula for future larger studies.

This study tested a new combination vaccine called mRNA-1083 that aims to protect against both flu and COVID-19 in a single shot. About 1,320 adults aged 18 to 64 took part. Researchers measured the immune response and checked for side effects to see if the combo vaccine works as…

This study tested the Moderna COVID-19 vaccine in over 4,300 healthy adolescents aged 12 to under 18. The goal was to see if the vaccine is safe and works as well in teens as it does in young adults. Participants received the main vaccine series, a booster, and an updated version…

This study tested updated mRNA COVID-19 vaccines in over 1,800 children aged 6 months to under 6 years. The goal was to see if these vaccines are safe and boost immunity against newer virus variants. The vaccines were given as a first series or as a booster shot.

This study tested an experimental mRNA vaccine (mRNA-1345) to protect against RSV, a common respiratory virus that can be serious in older adults. About 3,300 people aged 50 and older received the RSV vaccine alone, with a flu shot, or with a COVID-19 booster. Researchers monitor…

This study tested the safety and immune response of several Moderna mRNA vaccines for COVID-19, seasonal flu, RSV, and CMV in 308 healthy adults aged 18 to 75. Researchers monitored side effects and measured antibody levels after vaccination. The goal was to ensure the vaccines a…

This study tested a new mRNA booster shot (mRNA-1345) in 507 adults aged 60 and older who had already received a licensed RSV vaccine at least a year earlier. The goal was to see if the booster is safe and boosts the immune system's ability to fight RSV. Researchers measured side…

This study tested an experimental mRNA vaccine (mRNA-1608) in 303 healthy adults aged 18 to 55 with recurrent genital herpes caused by HSV-2. The goal was to see if the vaccine is safe and can reduce the number of outbreaks. Participants received different doses of the vaccine or…

This completed Phase 4 study tested whether an updated COVID-19 vaccine (mRNA-1273.712) affects heart muscle in healthy people aged 12 to 30. Researchers measured a heart enzyme called troponin in 1,000 participants who received either the vaccine or a placebo. The goal was to se…
