Aug
In Brazil until Saturday, the Ministry of Health distributed more
than 230 million of the vaccines against covid-19, these 187 million have already been applied, being 128.4 million in first doses and 59 million having completed the scheme, which gives 36 .9% of the population, and still not enough, as the new variants affect while the scheme is not completed.
The number of deaths and infections in Brazil has been falling slowly, but it is still in the range just below the 1,000 daily deaths of the moving average and close to 20,000 daily infections.
Extensive research carried out by FioCruz revealed that by completing the vaccination scheme, the AstraZeneca-Fiocruz and CoronaVac vaccines are effective against infection, hospitalization and death: AstraZeneca-Fiocruz with 90% protection and CoronaVac with 75%.
Thus, with 36.9% of the vaccination schedule, the current stage of immunization is still fragile, and the new protocols for flexibility have no scientific basis, except for research carried out with rigor and proven data, all information disclosed, even by official bodies, is not are reliable.
The infectologist and researcher at Fiocruz Julio Croda, said in an interview with CNN, that it is necessary to speed up vaccination to protect people more effectively against the Delta variant, and that the effectiveness drops for the elderly and people with comorbidities.
As for the possibility of using the mixed vaccine scheme, called interchangeability, a study conducted by the University of Oxford, UK, showed that the vaccines that show better immune responses are the combination of Pfizer and AstraZeneca, with an interval and four weeks, with the highest results being AstraZeneca followed by Pfizer.
Flexibility is the responsibility of government health agencies, but care is a personal measure that we can all take, while avoiding crowding, using masks correctly and using alcohol gel, must continue to follow the protocols.
A long period of pandemic also causes personal and psychological stress, it is necessary to find occasions for outdoor walks, relaxation in different ways and virtual contacts with friends and colleagues in the work environment.
