jim30 : "What do you meant exactly by "not really vaccines in the normal use of the word as it does not provide immunity"? There are some differences between, say, the Pfizer, Moderna, and AZ vaccines, and what might be regarded as more traditional "inactivated virus "
You did not mention live attenuated vaccines, which are sterilizing vaccines, which the UK administered covid vaccines are not. They are non-sterilizing immunizations.
"The biology of human immunity is incredibly complex, it is relatively well understood for certain viruses—polio, measles, mumps, and chicken pox—that generate sterilizing immunity after infection."
Some people think it a 'wonder' at the speed these mRNA vaccines for this novel corona virus were produced, but it is at least since 2004 that researchers were specifically producing mRNA spike protein vaccines, and indeed Fauci's own National Institutes of Health(NIH) conducting the research.
"In making the NIAID vaccine, researchers modified the fragment of viral DNA to minimize the risk that it could combine with the SARS virus or other coronaviruses, the NIAID said." - Dec 14, 2004
