The importance of including children on the immunization plan against Covid-19 was the main topic during the closure of the CoronaVac Symposium which happened this Thursday (9). For the researcher Susan Bueno, of the Pontifical Catholical University from Chile, as long the vaccination only advances for the adult population, the more the children are vulnerable to the SARS-CoV-2. Today, at least six countries already uses the CoronaVac on children under 12 years of age: China, Hong Kong, Chile, Ecuador, Indonesia and Camboja.
“Although a great part of the cases in the pediatric public are mild, there is still an important percentage of children that developed the severe case of the Covid-19, with multisystem inflammatory syndrome”, affirmed Susan.
During the event, the scientist presented preliminary data from the clinical trials of phase 3 of the CoronaVac in Chile, that is being realized in children from 3 to 17 years of age. The preliminary results indicate that the vaccine is safe for the pediatric public.
“In Chile, we have already proved that vaccination with inactivated viruses generates immunity in children. It is a vaccine platform that has been used on this population for decades with a good pattern of safety”, affirms Susan.
In China, which has already vaccinated over 120 million children, clinical trials of phase 1 and 3 already proved that vaccines induce a high production of antibodies in the public from 3 years of age.
“The response observed in children can be comparable to the response presented in adults. It is a strong immune response with high titers of neutralizing antibodies. We are working in Chile to evaluate the T cells response as well and may have the results for the next few months”, punctuated the researcher.
For the epidemiologist Paulo Lotufo, professor at the Medicine School of University of São Paulo, for the pandemics to be fought in an effective way, the whole population must be included in the vaccinal coverage. “Therefore, I believe that the vaccination on children is mandatory.”
