A disease cannot mutate if it has no viable hosts. Your opinion is objectively wrong. As in, literally kills people wrong.
It kills people who are in the high risk groups, yeah. Hence me saying the majority of the population, but not all
of the population. I believe in a person's right to choose their own medicine, but I am just saying that if you are a healthy individual who is outside of the high risk ages, then getting the flu isn't going to kill you. It would just be an inconvenience and that's all.
Yes, a healthy lifestyle helps your body fight off a flu, but a vaccine prevents it entirely. More importantly, the vaccine can prevent you from spreading the disease to others. No matter how in-shape you are, you are always capable of spreading the disease to a child or an old person, the very people who are at risk of death from the flu. Or people taking immunosuppressants due to organ transplant or people with compromised immune systems.
This is not correct in several ways. First, flu epidemiology requires the host to be infected for it to be spread, even if they are pre-symptomatic. Healthy individuals with strong immune systems won't become infected, even if they come into contact with the virus. If you are showing no symptoms and are spreading the virus, it means you are infected
and will soon show symptoms yourself. Humans can't carry
the flu. You are either infected or not.
Second, the flu will spread faster in unhealthy populations, regardless of vaccination status. If you compare the epidemiology of healthier societies that aren't vaccinated to unhealthy societies that are vaccinated, flu transmission and incidence will still be lower in the healthier society.
Even if you are
vaccinated, you can still become infected and transmit the virus to vulnerable people; all it would mean is that your infection period would be less since your body already has the acquired immunity. It doesn't mean you aren't contagious. For this reason, it is pointless to scapegoat people for choosing to not get the vaccination. Also, it's important to note that although vaccination increases survival rates in infants and the elderly, those who have been inoculated can still
die from the flu.
Medical technology places all of its efforts on combating the virus, such as through vaccines, and little effort on prevention through healthy lifestyle. The American population has a high index for type II diabetes and obesity, both of which lower immune response significantly. The virus would spread faster there than in comparatively healthier countries.
The short answer: Smallpox would like a word with you, sir.
I singled out the flu, and no other virus. I am not saying that vaccines are patently useless across the board. Smallpox vaccines were definitely a good idea, considering the mortality rate. I see no such justification for the flu, even H1N1.
