The tests showed that the vaccine pfizer Against the Covid-19 for children aged between 6 months and 4 years is “extremely effective”.
The statement is from Cristiano Zerbini physician and coordinator of Pfizer’s vaccine trials in São Paulo, during an interview with CNN this Saturday afternoon (17).
“I would say between 75 and 80% effective,” he said. “When a reaction occurs, such as low fever, body pain and headache, it passes quickly, in the first seven days.”
THE National Health Surveillance Agency (Anvisa) approved, on Friday (16), the use of the Pfizer vaccine against the disease for this age group.
“There are no major problems with the vaccine, there are no long-term side effects and most children have no adverse effects and are very well protected,” he said.
Zerbini also spoke about the number of deaths of children by Covid, which, according to him, is an “absurd statistic”.
“It is important to get this vaccine. From January to June this year, we lost 291 children to Covid-19. Since the beginning of the pandemic in 2020 until now, we have lost more children than 14 other diseases in the last 10 years. We need to vaccinate children,” she warned.
At the moment, the permanence of protection is still in the study phase. For Zerbini, soon the effectiveness could be up to a year after the vaccine.
Children who have already had contact with the disease can be vaccinated again and it is necessary to wait a month to receive the dose.
vaccine dosage
Anvisa says that the immunizing agent for children between 6 months and 4 years old has a different dosage and composition from those used for previously approved age groups.
“The authorized vaccine formulation must be applied in three doses of 0.2 mL (equivalent to 3 micrograms). The initial two doses should be given three weeks after interval, followed by a third dose given at least eight weeks after the second dose” explained the Agency.
According to Anvisa, the lid of the vaccine bottle approved for children aged 6 months to 4 years will come in a wine color, to facilitate identification by vaccination teams and also by parents and caregivers who will take children to be vaccinated. .
“The use of different cap colors is a strategy to avoid administration errors, since the product requires different dosages for different age groups”, he explains.
