The tetravalent flu vaccine is now available on the private network

Covid-19 control measures have also become a means of preventing the transmission of influenza. With the relaxation of these practices recently announced by some states across the country, respiratory viruses are expected to circulate again. To protect yourself from the flu, the solution is vaccination. Labi Exames, a laboratory whose goal is to offer clinical analysis tests and vaccines that are practical and at fair prices, and which was the first in Brazil to sell tests on the Internet, has already received its first shipment of vaccines against the flu to start the 2022 campaign.

“With the relaxation of measures concerning the agglomeration of people and the relaxation of the use of masks, respiratory viruses of human-to-human transmission will circulate more intensely”, estimates Dr. Octavio Fernandes, medical specialist in infectious diseases and vice -president of Labi. In 2021, due to doubts about the simultaneous vaccination of Covid-19 and influenza, many people prioritized protecting themselves against Covid-19, generating an influenza epidemic at the end of the year.

Each year, strains of the flu virus are identified by the World Health Organization. Based on this information, immunizers are developed by laboratories. For 2022, the influenza vaccine formula will have protection against the new Darwin virus (type A strain), responsible for the epidemic between December 2021 and January 2022. The Labi vaccines available for the 2022 campaign are quadrivalent, protecting against four different influenza serotypes: H1N1 (since 2019), H3N3 (since 2021), Austria type B (since 2021) and Phuket type B (since 2013).

“We cannot let the 2021 flu epidemic repeat itself, so we already have vaccines available both in our physical units and for home service and commercialization for companies”, says Marcelo Noll Barboza, president of Labi. People can seek out one of the Labi units to get vaccinated – without the need for an appointment – or seek home care. The minimum age for getting the flu shot is six months. From the age of nine, the vaccine is a single annual dose. As it is an inactivated vaccine, it does not cause disease.

The flu causes annual epidemics with peaks in autumn and winter, causing 1,000 to 3,000 deaths and around 6,000 cases of severe acute respiratory syndrome (SARS), one of the severe forms that also manifests in covid- 19. According to the Ministry of Health, vaccines against Covid-19 can be administered simultaneously with other vaccines or at any interval in the population over 12 years of age. Children between 5 and 11 years old must wait a period of 15 days between one vaccine and another.


Simple laboratory that offers practical clinical analyzes and vaccines at fair prices. Through technology and design, Labi has made the process more agile, efficient and safe.

It is the first lab in Brazil to sell tests online and the first lab to sell vaccines in a delivery app.

To make life easier for customers, there is Labi em Casa, a service for collecting exams and administering vaccines at home.

In addition, it has physical units that function as face-to-face, home and business assistance centers: there are more than 20 located in Greater São Paulo, Greater ABCD and Greater Rio de Janeiro.

Since its foundation, it has won several awards such as “100 Startups to Watch”, “Scale-up Health Tech Program” and “Top 10 Startups of the HealthTech Report District”, in 2020. In 2021, it won the Design for a Better World Award with the campaign #DiadeTODASasMulheres received silver in 3 categories at the Brasil Design Award, finished 4th at the Reclame Aqui award in the Health category among 10,000 companies from all over the country and 5th place at the iBest Award.
