EDIT: Just registered me and wifey for SARS-CoV2 Antibody test (happening in about three weeks). Hopefully we can circumvent vaccination and restrictions this way.
Had a strange cough last year in february, lasted 3-4 weeks.
Thanks for this comment. Never thought of not needing to be vaccinated due to contracting COVID-19 in January. My work position is "sensitive" and there are strict policies regarding our health matters (can't disclose more, sorry). If having contracted COVID-19 makes vaccination pointless, then I won't do it (if I can avoid it). Will need to check it out.
An infection will make your t-cells much more responsive on virus presence, even if antibodies are low. This helps avoiding a serious condition when infected.
Vaccines are expected to have similar results. The spike protein of the virus is unlikely to change, so that is a common vulnerability of all mutations, once the immune system "knows" the virus. Antibodies are more specific to the variant which triggered the immune reaction.
