CDC advisers recommend Moderna and Janssen booster doses in the US.

An advisory panel from the Centers for Disease Control and Prevention (CDC) recommended administering booster doses of vaccines against COVID-19 from Modern and of Johnson & Johnson (Janssen) for some cases.

The 15 members of the advisory panel voted unanimously in favor of the two recommendations.

In the case of Johnson & Johnson, experts advised a booster dose at least two months after the first for everyone who received this vaccine.

In Moderna’s, they equated their recommendation to the one approved a month ago for Pfizer, the other vaccine with messenger RNA technology, of an additional dose for those over 65 or people with immunosuppressive diseases six months after the second.

On the possibility of mixing vaccines, something that has been talked about for weeks, experts recommended without a vote that Americans receive the same serum for their booster dose as the one they were initially administered.

With the green light from the scientific committee, only the signature of the director of the CDC, Rochelle Walensky, is missing so that Americans can start receiving booster doses of Moderna or Johnson & Johnson starting this weekend.

The experts also remarked that, despite the recommendation of booster doses, all those individuals with the full regimen are still considered vaccinated.

The lengthy meeting coincided with the announcement made by Pfizer that the third dose has shown 95.6% protection against COVID-19 infections and behaves in a “safe and tolerable” manner.

The experts also evaluated the data presented to them on the efficacy of the Moderna and Johnson & Johnson vaccines.

These data suggest that the effectiveness of Moderna’s serum against COVID-19 infection decreases over time, something that does not happen as significantly with that of Johnson & Johnson, although the latter is less infallible when it comes to preventing infection.
