@Josh *******

, the body is not fully capable of fighting off viruses, but only partly capable. Medical science is the major reason why people are living about double the age than 100 years ago. Vaccines are one of the major miracles of medical science.

@Mat ********

, your numbers are not correct even it is true that high numbers are not getting sick and even less dies from Corona. However, people are still dying from Corona.

@Josh *******

, that's simply nonsense. The world has many highly effective vaccines. Influenza is not one disease but many. Vaccines exist for some but far from all.

Grant Stevens, wonder why you are not a candidate for the Nobel Prize? Your brain is so big that you are the next ruler of the entire world. Good luck... LOL LOL LOL

@Grant ********

, you keep talking about yourself. You have no clue but funny private ideas. 90% of the world population do not care about fools like you. BYE.

@Grant ********

, you are talking about "blind arrogance". You are talking about yourself here. Your idea that every minor mutation will make the vaccine ineffective is showing nothing but a blind arrogance. This is not how vaccines work. Vaccines are not making a full exact match but are reacting on specific characteristics. Only if those characteristics change, the vaccine becomes ineffective. Update yourself on the basics of how vaccines work instead of talking about exactly your own blind arrogance and self-importance being unable to face the fact that thousands of virologists might know better than you... OVER AND OUT.

@Grant ********

, you are clearly mixing up your private ideas with data, and naming ppl not agreeing with your theories to be led by "blind arrogance". We all know the funny sources you are linking to. Yes, there are potential challenges with the vaccines for Covid-19, but very far from what you are talking about. Yes, there might come monster mutations erasing the effect of the vaccines. But nothing indicates this as a present situation. Also, yes, no one knows yet how long the vaccine will maintain antibodies, but only 3-6 months contradicts the data collected so far.

@Grant ********

, when your own theories based on YouTube videos take over, then discussions are pointless. The virologists have very different ideas from you and your son. You are completely mixing up the effect after the first and second shot. It is the other way around that the effect rises significantly after the second shot, not the other way around. You are obviously searching for "evidence" proving your preconceptions made up from conspiracy theories. When you start with preconceptions instead of data, then you are filtering out all the data which are not in line with your preconceptions. That's the difference between religion and science.

@Grant ********

, you have your own very private ideas about vaccines only working for a short time. How about all the vaccines of the world? Did you forget about vaccines from before? Measles, smallpox, etc. those vaccines are not only 35% effective. Your mind seems to be ruled by conspiracy theories.

@Grant ********

, then why are the virologists saying very different from you? The virologists are very strong on this matter that some mutations have no impact on the effect of the vaccines, while what they call "monster mutations" might erase the effect completely. Therefore, the mutations of Covid-19 are monitored very closely. However, some vaccines are easy to adjust to new mutations, while monster mutations might reset the development of the vaccines completely. If you were right, then how come that the world has had stable vaccines for measles, smallpox, etc. for decades?
