The United States Drug Administration (FDA) has authorized the booster dose of vaccines against covid-19 Modern and Janssen, and has approved the option to mix sera.
According to the United States Drug Administration, the second dose of Janssen’s vaccine can be applied two months after the first to individuals over 18 years of age, while recommending the reinforcement of Moderna six months after having received the complete guideline for certain groups.
In the case of Moderna, it authorizes the additional dose for those over 65 years of age, as well as for those over 18 who are at risk of suffering a serious covid or with jobs that imply being exposed to the disease.
