The new stage is available for people over 50 years old who have already completed five months after receiving the first booster, as well as teenagers of 12 years old with moderate or severe immunosuppression.
“This booster is for those who have health complications or a depressed immune system,” the Minister of Public Health, Ximena Garzón, specified.
It is also available to health sector workers, including administrative staff of medical institutions and those over 18 years old with a first inoculation abroad with the Janssen vaccine (Johnson & Johnson).
Another sector that will benefit exclusively will be travelers whose country of destination requires two doses of authorized vaccines (Pfizer, AstraZeneca, Sinovac) for entry.
In these cases, the second booster will be inoculated 28 days after the first one.
According to a research, four to five months after the third dose, a fourth booster increases the immune response in the individual and restores the antibodies to maximum levels.
The process is taking place in the midst of a steady decline in Covid-19 cases and deaths from the disease.
