That’s why Moderna, the company behind the vaccine, is currently updating the vaccine to make it protect just as well or better as the original vaccine. However, its efficacy against infection from new variants is lower than its efficacy against the original variant. The vaccine has so far proved to be resistant to the various virus variants and mutations that have emerged in Denmark, including the Omicron variant. To be fully vaccinated with Moderna’s COVID-19 vaccine, you will need two vaccine doses about four weeks apart. The higher the infection rate, the greater the impact of vaccinating people, in overall terms. The benefits that the vaccines bring to the entire population are fewer hospital admissions, fewer severe disease cases and fewer deaths. If you have been vaccinated, you can still get ill if you are exposed to virus, but you will typically have milder symptoms than if you had not been vaccinated.
Moderna side effect after one week trial#
In other words, there were 94% fewer cases of COVID-19 among the trial subjects given the real vaccine than among those given a placebo. Prior to its authorisation, the Moderna vaccine was tested in major clinical trials with more than 28,000 voluntary trial subjects over the age of 18, and the vaccine demonstrated 94% efficacy against coronavirus two weeks after the second vaccine dose. The COVID-19 vaccine from Moderna works by strengthening the body’s ability to defend itself against infection with coronavirus (COVID-19).
