According to the R7 portal, an estimated 4.6 million Brazilians will receive this second batch of reinforcements.
The restriction stipulates that the application must take place four months after the first (or third) booster vaccination. The orientation is that the injectable substance is preferably from the American laboratory Pfizer.
Alternatively, immunizers from the Belgian companies Janssen and the Swedish AstraZeneca can also be used.
Before the guidelines, the socalled fourth dose was only given to people including adolescents with immunosuppression. That is, groups with problems in the immune system.
In the text, the portfolio acknowledges that there is little data on the extent and duration of a fourth booster dose.
However, “depending on the epidemiological situation and the availability of the vaccine, different vaccination strategies should be used by the countries.
In addition, the emergence of worrying new variants must be taken into account, particularly when recommending to the most vulnerable groups.
The decision to include the fourth dose was made by the Immunization Technical Advisory Chamber (CTAI), which took into account the lower efficacy of the vaccines in this population.
Now the CTAI is investigating the need to expand the fourth dose to other age groups. The strategy served immunocompromised people for 12 years. “The Ministry of Health is monitoring the need to use the second booster in other age groups and the recommendations may be revised at any time,” the statement said.
Since March 21, the government of Sao Paulo, the country’s most populous and wealthy state, has been applying the fourth dose of the vaccine to people over the age of 80.
“With the confidence and support of the scientific committee (the pathogen) we have moved on to the fourth dose. The recommendation is that all immunizers available on the network can be applied in this new phase,” Governor Joao Doria said.
The board took into account the high mortality rate among the elderly in the age group during the spread of the Omicron variant of the SARSCoV2 virus, which causes Covid19, when making its decision.
Sao Paulo and the city of Rio de Janeiro also decided to end the mandatory use of a mask in open and closed environments, except in public transport and health centers.
In general, Brazil records 657,000 998 deaths and 29 million 729,991 infections due to the disease.
