The Centers for Disease Control and Prevention (CDC) approved this Thursday the administration of booster doses of the Covid-19 vaccines from Moderna and Johnson & Johnson (Janssen) for vulnerable people.
In addition, health authorities will allow people to get a booster dose of a different vaccine than the one they received before.
According to estimates by the US media, about 100 million people will be able to access the booster doses due to the risk they have of suffering from severe Covid.
Earlier this Thursday, the CDC advisory panel recommended the doses unanimously by the 15 members.

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 had been talked about for weeks, the experts endorsed the recommendation without it being put to a vote.
Following approval from the advisory panel, CDC Director Rochelle Walensky signed the documents so that Americans can begin receiving either Moderna or Johnson & Johnson booster doses 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 long 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.
