CDC Advisors Recommend Moderna and Johnson & Johnson Booster Doses in US

An advisory panel from the Centers for Disease Control and Prevention of USA (CDC, in English) recommended this Thursday to administer booster doses of the vaccines against the covid-19 of 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 for at least two months after the first one for everyone who received this vaccine.

In the of Modern, 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 noted that, despite the recommendation for booster doses, all those individuals with the full regimen are still considered vaccinated.

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

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

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.
