WHO publish proposals for the 2019–2020 seasonal flu vaccine from a northern hemisphere


The WHO proposals for using influenza virus vaccines for use in influenza flu vaccines in 2019-202020 have now been distributed.

The increasing nature of influenza viruses requires the occasional rewriting of viruses in influenza vaccines. As a result, WHO will hold 2 annual consultations – 1 for northern heifers and 1 for a southern hemisphere – to monitor virus monitoring data received from the Surveillance Service and the WHO Global Impact Response. (GISRS), and recommended the recommended flu vaccine for the following flu season.

The proposals are then used by the national vaccine governing bodies and the pharmaceutical companies to develop, produce and permit influenza vaccines.

What European Department helped to achieve the best flu vaccine

These recommendations have been made possible by national flu centers (NICs), which source and identify viruses and share these with WHO collaborative centers for detailed analysis. During the annual consultation process, an advisory group of experts is testing the data the countries are giving to propose the new pieces. This year, NICs in European WHO have tested over 360 000 clinical eyes and found 57 443 influenza virus. NICs in 44 countries in the Department shared viruses introduced to the analyzed data, leading to the new proposals.

Changes to previous season's recommendations

Two strains of influenza virus cause illness in people, type A and type B. Although no change is proposed for the components of influenza B virus, it was proposed to change the component A (H1N1) virus. . Virus A / Brisbane / 02/2018 (H1N1) resembles the first subdivision 6B.1A replacing the virus A / Michigan / 45/2015 (H1N1) pdm09 which is included. members 2018–2019 vaccine. world-wide.

The final limit

The WHO proposals for the use of influenza viruses are intended for use in influenza season in 2019–2020 from the following: t

  • virus similar to A / Brisbane / 02/2018 (H1N1) t
  • virus A (H3N2) published on 21 March 2019 *
  • similar virus / B / Colorado / 06/2017 (B / Victoria / 2/87)
  • similar virus / B / Phuket / 3073/2013 (B / Yamagata / 16/88 line).

The first 3 suggest a virus strain to be included in flu vaccines, and the last type to be given is the additional virus strains given. it will be included in appropriate flu vaccines.

The WHO Consultation and Information Meeting on Co-ordination of Influenza Virus Surveys was held in Northern Hemisphere 2019–2020 on 18–21 February in Beijing, China.

Vaccination – the most effective measure to prevent serious disease due to inactivity

Interim results of vaccine efficacy are recommended, in the 2018–2019 season, that vaccination was reduced by less than half in the hemisphere of people suffering in infections. middle, and this result was better than children.

There is safe flu vaccine and the main measure of flu and reducing the impact of infection. WHO is recommending healthcare workers and people most at risk of serious illnesses from influenza disease – the old people, people with chronic illness, heavy vaccination and young children – every year t before the season started.

* A selection of influenza A (H3N2) flu vaccines from 2019–2020 has been delayed. The influenza A (H3N2) viruses have brought greater challenge to the selection of vaccine viruses due to the common fluctuations in the virus itself and the problems of producing viruses for candidates who have been vaccinated against vaccines. used in the production of vaccines on eggs. In recent months, the proportion of viruses in one different body has increased in many countries. This delay will allow more time for monitoring the circulation of virus and the removal of appropriate vaccine viruses.
