So what is your idea? Bring the whole world together to catch cold, SARS (which was also more deadly than COVID) or the flu (which can also be deadly)? Meanwhile, COVID, which is highly contagious, rips through the world, flooding hospitals and overloading health workers.
I am utterly bewildered at the lack of logic. I've had 70 years exposure to colds and flu. I can't imagine anyone my age not having one, other or both at some time in their lives. COVID has still afflicted people in my age range and a disproportionate number have died.
People were not sent to work in farmyards in order to overcome smallpox. They were given vaccines. People don't need to go to school to get a cold or the flu. Schools are the perfect incubator for diseases that are then spread through the community. Kids go home sick. Parents catch it and take it to work. So the cycle continues.
A side effect of COVID restrictions is that the flu is virtually non-existent in the Australian community. The medicos are concerned that the population will be more vulnerable to flu when restrictions are eased, which is happening now. Your simplistic arguments do not stand up to any reasonable examination.
your simplistic vaccine is not standing up to any scrutiny.
my strategy is based on science. A robust immune system is science. Eat right, get sleep, get exercise has been proven to improve health.
Stop spreading this fear porn which is more damaging than anything.
People who are at high risk will of course take far more precautions than those who aren't. But those who are healthy and have no abnormal reason to fear should get out. Go to outdoor events like rallies, vaccine protests, etc. All of those events that were called "super spreader" events never turned out to be. As a result large number of people would get a mild exposure so that they could become immune.
Herd immunity is when 80% of the population (give or take) is immune. Even if 20% are too high risk to go to crowded parks and other outdoor events the fact that 80% are going benefits them by tamping down on the spread of this thing.
Social distancing has been proven to be effective (3 feet gives you the benefit, 6 feet is excessive). But even more making sure no one goes out into public that has a fever (take temperatures at the door) or symptoms is a very effective method at reducing the viral load with which you are first exposed and that is a very critical factor in determining how sick you get.
use therapeutics. HCQ has been proven effective in Africa, and Ivermectin has been proven effective in India, and oxygen is extremely helpful for those who are very sick.
Now if you are doing all these things by all means develop an effective vaccine that has been tested for 12 years and shown to be both safe and effective. Make sure your data collection and analysis is transparent so that the whole world can see and trust it. Do not do stupid things that undermine trust by censoring any questions, saying that questioning the person pushing this is to "question science", mandate an experimental vaccine, change the definition of a vaccine, coerce people to get the vaccine with free french fries or threaten to fire them if they don't get it, set up quarantine camps and a whole host of other tyrannical moves, and call on the military to give the vaccine by force. Basic science. Logical really.
