H1N1 is a global pandemic of the worldwide worldwide influenza now. Swine influenza epidemic in Mexico in April 2009, the World Health Organization (WHO) lifted the alert level to the global epidemic by 11 June. Virus spreads rapidly all over the world. Fortunately, the Canadian government and other governments are currently providing immunization vaccines against the epidemic. This is currently available to some citizens. In the 2009 Hastings Center report, "Swine flu vaccine: What is fair?" From Lawrence O.
2009 H1N1 Influenza Pandemic (New Influenza A H1N1 strain), highly pathogenic avian influenza strains (A / H 5N1 and A / H 7N9) and past unpredictability of seasonal influenza vaccine mismatch virus and global response to emerging strains Currently, influenza A (H1N1) and H3 subtypes are prevalent. Direct transmission of highly pathogenic avian influenza virus to humans (such as influenza A / H 5 N 1 influenza, and more recently influenza A / H 7 N 9) poses additional threats, but this strain does not yet demonstrate the ability to spread effectively Hmm. Vaccination is still the preferred way to control influenza; however, the annual large-scale vaccination challenge now requires special attention to the child, the need to improve vaccination for all ages It is beyond the capacity of a country with limited resources.
Seasonal influenza vaccine prevents influenza virus, and research showed that virus is the most common in next season. Trivalent vaccines are used to prevent three influenza viruses, influenza A (H1N1) virus, influenza A (H3N2) virus, and influenza B virus. The tetravalent vaccine can prevent four viruses, the same virus as trivalent vaccine and another B virus. The influenza vaccine is safe. Serious problems concerning influenza vaccine are very rare. The most common side effect that a person may experience is the pain given by injection. This is usually mild and usually disappears in 1 or 2 days. For more information, please see the safety of influenza vaccine.
The influenza vaccine can prevent three or four influenza viruses. The trivalent influenza vaccine prevents strains of two influenza A strains - H1N1 and H3N2 - and influenza B virus. The tetravalent influenza vaccine originally offered during the 2013 to 2014 influenza season can prevent the same strain as the trivalent vaccine and additional strain of influenza B virus. In addition to the standard dose of influenza vaccine given via injection needle, high dose version of elderly people aged 65 years and older and small injections for people aged 18 to 64 years (intra injection of influenza vaccine) There are several different forms of influenza vaccine. A version without eggs growing in animal cells rather than eggs, nose spray is suitable for people over 4 years old, healthy people between 2 and 49 years old.
