I have seen those a few times now.
Are they hyperbolic or just really uneducated?
Creating a vaccine against a virus that 99% of the global population can eliminate alone is nothing miraculous. Vaccine work by training the immune system to defend better. Moderna and Pfizer have created their vaccine in a single week end, without seeing a single virus. The russian have created their vaccine in a fortnight. The chinese too. The testing has been sped up to tackle the pandemic, but the technique are nothing miraculous nor impressive for anyone followng the science a little bit.
By the end of the year, dozens of different vaccines will bee avalable, the different techniques are all being mastered quickly by everybody.
Wake me up when someone find a HIV vaccine, a virus which has defeated dozens of billons and resarch thrown at him. That would be a real science advance. Not a vaccine against a weak and tiny coronavirus which will be extremely useful and will save a lot of lifes but are easy and nothing groundbreaking.
