FDA Authorizes Moderna and J&J 1:13 Booster Doses
(CNN) -
The authorization process vaccines covid-19 can be confusing.
Next, we explain the current situation of covid-19 booster vaccines in the United States.
Pfizer
In September, the US Food and Drug Administration and the US Centers for Disease Control and Prevention (FDA and CDC, respectively) authorized boosters of the Pfizer / BioNTech covid-19 vaccine. for adults 65 years of age and older, adults at high risk of severe COVID-19 illness, and adults with possible frequent exposure to coronavirus through their work. These boosters were authorized only for people who had received the Pfizer vaccine at least six months previously.
On Wednesday, the FDA cleared the Pfizer / BioNTech booster for those who may be eligible but are fully vaccinated with the Moderna or Johnson & Johnson coronavirus vaccines, as a mixed approach.
At this time, CDC vaccination advisers are considering recommending such a mix and match, and will take turns for approval by the CDC director.
If you do, the mix-and-match boosters could be available to the public in a matter of days.
Also today, Pfizer and BioNTech announced that the booster dose was highly effective at 95.6% against COVID-19 in a phase 3 trial.

Modern
The FDA authorized this Wednesday the emergency use of a half dose of Moderna's vaccine as a booster for people who have been fully vaccinated for at least six months who are at least 65 years old, or who are at least 18 years old and at high risk of suffering. severe covid-19 or have frequent institutional or occupational exposure to the virus.

Johnson & Johnson
On Wednesday, the FDA authorized booster doses of Johnson & Johnson's vaccine for anyone who received it at least two months ago.
The J&J vaccine is licensed only for those 18 years of age and older.
The company announced last month that a two-dose version of the vaccine provides 94% protection against symptomatic infection.
If the CDC director gives the go-ahead soon, people could start getting reinforcements from Moderna and J&J in a matter of days.
Combination of reinforcements
The FDA said any of the three licensed vaccines could be used as a booster in a "mix and match" approach.
Dr. Peter Marks, director of the FDA's vaccine section, the Center for Biological Evaluation and Research, said the ability to use any licensed vaccine as a booster will make things simple for people.

Combining covid-19 vaccines has two benefits: stronger immune responses and less confusion
The FDA said it had decided to allow the combination of booster vaccines after researchers from the National Institutes of Health (NIH) presented their findings last week to their vaccine advisers.
Although the results were limited, they made it clear that mixing the different vaccines was safe.
If the CDC director gives the go-ahead soon, people could start getting reinforcements from Moderna and J&J in a matter of days.
