Senior Scientific Advisor Fiocruz and one of the main references to vaccination in the country, researcher Akira Homa, In the interview with Folha de S.Paulo, told about his opportunities the appearance of yellow fever in the summer, and protect vaccination as one of the main measures to fight the disease.

"We are victims of our success; people feel safedo you think there is no epidemic"says Phiocrose, a physician working in a vaccine block, Bio-Manguinhos, and from 1989 to 1990.

Homme warns about this Southern Yellow Fever in recent years in our country and in the near future Fiocruz he showed the virus Last year, the South-East region spread about three kilometers per day.

For this purpose, There is no danger of vaccine deficiency, and Brazil can safely use fractional doses. "This is not a low quality vaccination, we have data: it also protects it because our vaccine capacity is very high," he said.

Check out your interview:

What is the chance for yellow fever in Brazil in the summer?
There is a potential for this. Last year, the marijuana came to Espírito Santo, Sao Paulo, Rio de Janeiro. And in these regions it was very immunized. But the virus is a matter of three kilometers per hour in the south [referência à taxa média de dispersão do vírus na região sudeste, durante o surto de 2017, segundo pesquisa recente da Fiocruz].

This region has no subject of vaccination campaigns. The large population of the population can be sensitive to the pancreas. Now, in summer, the temperature is raining and raining. Opportunity [de um novo surto] installed.

In your opinion, what should be the vaccination strategy in the country?
It is very well planned and should be well-educated. People need to know the concrete facts. For example, last year mushroom vaccination was a major problem because the ministry was unable to adequately inform the population. Our vaccine has a lot more vaccine in the normal dose, and many antigens are required.

Does this mean that partial vaccination is safe?
We have done a published study; we have scientific data and arguments. We diluted the vaccine. Even when declining ten times, the vaccine still had a full dose-like seroprotective. But to use it, I have to prepare a different vaccine formula, and for that I need Anvisa company authorization. [Agência Nacional de Vigilância Sanitária].

To avoid anything, for example, instead of using 0.5 ml of dose, we recommend that you use 0.1 ml, which is a fifth of the dose. The fifth power. But nothing has changed in the vaccine. That's all the same. You will restore the vaccine as it is; quality is the same. Just fractions.

Does it work the same way?
It works. Antibody production is at full dose level. This year we have delivered more than 40 million doses [de vacina contra a febre amarela]. If we take fractional doses, it will be 200 million doses. So I have security: if properly organized, planning first, vaccination will be a vaccine for all the major regional risk vaccines.

Last year there were cases of diseases such as yellow fever and beetroot in Brazil. What happened? Was vaccination unsuccessful?
I say: we sacrifice our success. Vaccination is a very successful program in Brazil. Poliomyelitis and beetles were eliminated from the country. The people feel safe and think that there is no illness. Now we have no epidemics, we have a lot of diseases of measles, mumps, rubella.

But there are other reasons [para a queda nas taxas de vacinação]. For example, difficulties with reaching health posts. Each of them needs to work, and there is nobody to involve children in vaccination. There are also financial problems: the municipalities face many problems, and often they can not effectively and effectively provide vaccination services. This is a serious problem.
Look at the latest vaccine campaigns, beetles and polio: there was a lot of information in the media. I have not seen so much everyday. But the people's response is not what we expect. We had to reach 95% of children. In Rio de Janeiro, we were only in 2 months. Two months!

In 1980, the national immunization program for mass vaccination was launched for poliomyelitis, and we received it for two days.

But what about preventing people from getting vaccines?
This is a serious problem. Population vaccination is not priority. We have to find ways to encourage these people to vaccinate. They talk about negative reactions: "Oh, if I have a reaction, why do I take a vaccine?" But the benefit of vaccination is far greater than a few negative reactions that can be vaccinated.
Fever, pain, and other minor reactions are restored in two, three, four days. And the loss is much more than a disease. The cost of treatment, the emotional load … you are much better at vaccination. No comment.

What is the effect of anti-virus movements on this issue?
This should have a bearing on the use of this information, which people no longer want to vaccinate. But that is false news.

Advantages of vaccination should be informed about the need for vaccination. Vaccination provides individual protection, but collective protection is only achieved when you have a high vaccine. That's why vaccination is important for everyone. It protects you and your family and your community.

Is the vaccine the main way to prevent yellow fever?
Vaccine is the only way to protect yourself, but we have to manage Aedes aegypti mosquitoes in the city. This is important because it reduces the likelihood of contamination.
