Good work! I must add a few comments.

1. Not sure if universal vaccine is the way to go, as vaccine designed today have an alarming amount of heavy metals (aluminum, mercury, ...), but also other very bad elements like antibiotics. Keep in mind that heavy metals like aluminum are not supposed to be in the body (aluminum didn't exist 400 years ago), and thus you can imagine the terrible consequences for the body (autism, alzheimer, weakened immune system, autoimmune disease ...).

2. Vaccine do not protect in the long term and that is why people have to get vaccinated again, again and again. Scientists are working on an alternative method to vaccine based on synthetic genes. You can find more details with this link : https://www.nytimes.com/2015/03/10/health/protection-without-a-vaccine.html .

3. Vaccines, especially for something like the flu virus do not work, in fact people that are vaccined with the flu vaccine are sicker. If those vaccines were working, there would be not one getting the flu anymore. There are natural ways to fight for the flu virus such as intravenous vitamin C (or L-ascorbic acid) at high dose (>5 grams). It is natural and it does not harm the body.

If you have a question or comment please let me know, but good work!
