![]() Really changed a lot, but there are two point It's basically the same as it used to be, it hasn't What is the common Type B strain that you guys Time away, and you come back, and you visit the You're doing the Type B strain,Īnd you're saying, well, yep, it hasn't changed yet. Start out, and you live close to the purple people. You'll get a real good idea of how much change happened ![]() Of your job- comparing to initial strain. Like on day one of your job? So when I say Genetically different is it compared to what it was So that's all we careĪbout- not all the strains, but just the dominant strain. What's happening with the dominant strain. To do is basically track out over that year The next 12 months, you're going to actually have Little bit of space, and let me tell you what Type B's circulating, but the dominant strain is the The same is true over here in the purple community. Of Type A's affecting the orange people, but this The orange community, and what I've drawn for you Now there are manyĭifferent types of Type A that are affecting So that's what you learn in theįirst kind of day on the job. And influenza Type B also has eight strands of RNA. So these people over here are having influenza Typeī. You find that over here, peopleĪre also getting the flu, but it's always because of Typeī. So let meĪctually write that over here, Type A. That seems to be affecting people is Type A. Types of influenza, and, over here, the only one The orange community, turns out that they really only That's pretty interesting, which is that, in Most common influenza type is that's circulatingĪnd the first thing you discover is something ![]() Into these communities, and find out what the If next year, a different strain of influenza happens to be the one that you come across, you are left with no protection at all ( after having to go through being sick with the flu the previous year!) So its better to get protection against the 3 strains of influenza that you are likely to see each year, than it is to get sick for a few days and then have really long lasting protection against a strain that you probably never going to come across again anyways.Īnd a purple community, and they're separate It is true that if you got really sick from a specific strain of influenza, you would be protected for longer against that specific strain of influenza in the future, but the protection you get is only for that specific strain. Assuming that you did not die from getting a strong strain of wild influenza (Most healthy adults would be fine and just be sick for a few days, but infants, elderly, or immunosupressed might not) you would only be protected against getting that exact same strain of influenza again, as compared to the 3 to 4 strains of influenza that you would be protected against if you had gotten the vaccine. As for getting the virus itself rather than the vaccine, definitely not better. As far as medications go, there no other group of drugs or medical treatments anywhere that have been as well studied or that have as strict of safety regulations as do vaccines. Its true that flu vaccine manufacturers do profit from making the influenza vaccine, but that in no way means that the manufacturers don't care about vaccine safety. This can be very dangerous, and can cause flu pandemics. What you are referring to is when a avian influenza and a human influenza virus both infect a pig, and then there can be genetic shift within that pig (the mixing vessel) forming a totally new strain of human influenza that we have not seen before. ![]() Humans cannot act as a mixing vessel for avian and human influenza because avian influenza cannot really infect humans directly (unless you exposed to massive amounts of avian influenza, and even then its unlikely that you would be able to spread that avian flu to another person).
