The animation was published on the website of the Hungarian Academy of Sciences, which explains the functioning of vaccines in a really understandable way.

Perhaps it will also convince the anti-vaccinationists that any vaccine is better than a ventilator.
As written on the website: Several types of vaccines are now available for effective protection against the epidemic, the operation of which is based on different principles, but the immune reaction they trigger, which prepares the body for protection against subsequent viral infection, is the same. The development and subsequent effects of this immune response are presented in the animation of the Hungarian Academy of Sciences, which was produced under the direction of Anna Erdei, Deputy Secretary General of the Hungarian Academy of Sciences, professor of immunology at ELTE TTK.
