Both are mRNA vaccines that induce high levels of virus-fighting antibodies. Both reduce the risk of infection and of transmitting an infection to others. ... Moderna's vaccine had an efficacy of ...
The Moderna news followed preliminary results from the Pfizer-BioNTech vaccine candidate, BNT162b2, with Moderna demonstrating similar efficacy, but requiring storage at the temperature of a standard medical refrigerator of 2–8 °C (36–46 °F) for up to thirty days or −20 °C (−4 °F) for up to four months, whereas the Pfizer-BioNTech ...
The COVID-19 mRNA vaccines from Moderna and Pfizer–BioNTech had short-term efficacy rates of over 90 percent against the original SARS-CoV-2 virus. Prior to mRNA, drug trials on pathogens other than COVID-19 were not effective and had to be abandoned in the early phases of trials. The reason for the efficacy of the new mRNA vaccines is not clear.
On 16 December, WHO recommendations on heterologous vaccinations suggested a general trend of increased immunogenicity when one of the doses is of an mRNA vaccine, particularly as the last dose. The immunogenicity of a homologous mRNA course is roughly equivalent to a heterologous scheme involving a vector vaccine and an mRNA vaccine.
Moderna today unveiled the latest on its efforts to expand beyond COVID vaccines before its R&D day on Wednesday.It announced, for instance, the positive Phase 3 results of its mRNA flu vaccine ...
The next day, the committee also recommended that a second dose be generally distributed for the Janssen vaccine, at least two months after the first. An FDA analysis cited that a single dose of the vaccine had a consistently lower efficacy in comparison to the mRNA vaccines. [110] [111]
The Food and Drug Administration (FDA) has approved Moderna’s RSV mRNA vaccine for adults older than 60 years. The approval makes RSV the second disease for which an mRNA vaccine has been ...
