influenza vaccine

Every biological product company in China produces influenza vaccine ingredients (this winter and next spring) recommended by the World Health Organization, including H1N1(H1N1), H3N2 and B (B), which are the same as last year. Also known as the common influenza vaccine, it contains what we usually call influenza A and influenza B. ..

There may be few side effects after inoculation, such as low fever, slight redness and pain at the injection site. These reactions usually disappear within 1-2 days and generally do not need special treatment. A very small number of vaccinated subjects have adverse reactions such as neuralgia, paresthesia, convulsion, transient thrombocytopenia, severe allergic reaction (such as anaphylactic shock), vasculitis and nervous system diseases.

In the winter of 20 10, I also inoculated myself with the adult common influenza vaccine (including H 1N 1, H3N2, b). No side effects, less common cold and positive effect.

By the way, there was an outbreak of influenza A in the second half of the year before last. At that time, the biological products company in China had produced common influenza, but did not include influenza A strain (H 1N 1), because H 1N 1 was a mutant strain and a new strain, which made people panic. Later, in order to celebrate the National Day in China, the first country produced and used a vaccine specifically for influenza A (referred to as influenza A, which contains only one strain), and vaccinated it free of charge. After the second year, H 1N 1 strain was incorporated into the common influenza vaccine, so the common influenza vaccine in these two years contained. B strain used to be directly contained.

You can also consult the vaccination clinic to check the strains on the vaccine instructions. All influenza vaccines in China contain the same strain.
