This is a new approach to vaccination.
The body’s cells will read the vaccine molecule as a microbiological instruction to create a vital part of the outside of coronavirus. Then the body will make antibodies against this innocent coronavirus-part. That takes the body about six weeks. If after that, coronavirus enters the body, it will react with a massive outburst of these antibodies. It was proven already that these anti-bodies are deadly for the virus.
Mass trials are needed to determine how much and how often the vaccine should be given and if there are side effects for different kinds of patients that could be problematic. You can’t vaccinate billions of people and then find out that for millions it’s not effective or damaging.
Another approach is also progressing. The first is active immunization. The second is passive immunization. The second has less of a chance to work in humans. It’s a cocktail of eight different antibodies that worked against the first SARS-coronavirus. The former lets the body make the antibodies; the second injects the antibodies ready-made. But the former is ahead in getting ready to apply to humans. In fact, the US is already producing the former in case the trials come out well, as expected. Then it will have the stuff ready to distribute. That is a costly gamble but if it’s a good and safe vaccine, marketing speed could save lives.
Another attempt to offer passive immunization is underway in China with copies of 14 different antibodies administered in one go. It suggests that it could be ready before winter, no doubt because China isn’t a democracy. Its leaders can do whatever they please. But, just as with King Trump, there is no way to know if their approach is working and safe or not.
Meanwhile, the Israeli population shows some evidence that anti-TBC immunization of decades ago does not protect against the COVID-19 virus. But it’s still possible that fresh immunization with that vaccine does work.
The moral of the overall story: play it safe until there is a vaccine for you.
