I knew right off the bat but went back and confirmed that the flu vaccine contains three to four strains of the flu each year. I also know it's a crap shoot each time they develop the vaccine. Yes they actually do inject you with a small dose of the actual vaccine that they grow or produce in one way or another. There is never any claim made that they get it right each year, last year they were way off and the vaccine was essentially useless for the flu that last year. This year the RSV virus hit particularly hard, it's not a influenza but it does act similar to flu symptoms. I know because my entire immediate family kept getting it. The first bout was the hardest with them throwing up. The second round wasn't as bad....and because everyone kept getting sick I went and looked up what the emergency rooms doctors told them they had when they went in the first time. Seems the virus can live on surfaces in the home and cause reinfection. I went to the store and bought them lysol disinfectant spray and told them they had to wipe down all solid surfaces with the lysol wipes, especially door knobs then spray the spray around to land on all the surfaces they couldn't wipe down. That took care of it. That really messed up all my planned baking and arts and crafts with the grand kid prior to Thanksgiving and Christmas, we actually ended up doing Christmas crafts the week after Christmas when they still had another week off from school. Though I wasn't as exposed to them as I usually was because they were to sick to come over I was the only one exposed to them that didn't get sick but I was also the only one who got a flu shot. Like I was in close contact with my one son as I'd take him to work every morning and I took my grandson to school so before he started running a fever I was exposed to him coughing in the car also. So this virus was all up in my car and the surface of my car but I never got sick. The thought did enter my head that maybe my flu shot gave me some sort of immunity of protection. I never use to get the flu shot as I always thought when I got sick it was a cold. About ten years ago I started getting them and I haven't gotten as sick as I use to since. I rarely get sick at that now. I'll keep getting them because I hate to be sick. Granted I take extra precautions during the winter months especially close to the holidays. I go to the stores later at night when it's less crowded, I've even had to take people to the store during the day and waited in the car if it was crowded.

As far as the corona virus is concerned the reason they haven't been able to make a vaccine as compatible as the flu is because at first they thought it was as simple making a live virus to spike the immune system. When they tried, as stated, injecting a live virus into mice infected with the virus caused more damage. They have to cover all the bases and different possible scenarios. They were and have been failures. What they have found though it the answer actually may lay with finding a way to stop the spike factor that all corona viruses tend to have, that's the crowd of the virus that enables the virus to spread through the body. So now they are not even dealing with trying to fight the virus with the virus through an immune response they are trying to find a way to top it by control the spike factor. If they can figure that out they may be able to control corona viruses altogether.

Where all this other misinformation comes from is the fact that it's important to work as a collaborative across all countries in the fight to offset any potential pandemic, therefore they release the structure of any new virus into a data base available to all. That's where there keyboard scientist who couldn't get a job in a notable national lab if they tried latch onto them and spread their home brewed theories to people like you who evidently have nothing better to do all day then to sit around and watch them.
