> Vaccines reduce the chance of them spreading it [..] "Citation needed"... Covid vaccination did not reliably or durably block SARS-CoV-2 transmission, especially after Omicron and as immunity waned. https://pubmed.ncbi.nlm.nih.gov/39971395/ The overall VE [Vaccine Effectiveness] of the complete primary series against infection with any SARS-CoV-2 variant was 70.7%. VE was lower for Omicron, at 26.1%, than for pre-O…
Leaving aside the linked study is looking at vaccine effectiveness WRT infection rather than transmission , ... Low effectiveness still agrees with the point made above about reducing chances of spread and transmission. A reduction is still a reduction, even if is not a 100% total and full stop.
The advice I was given from our family doctor was that having had an utterly mild case of (actual) Covid, as I had (two separate times!), during the pandemic, was significantly better in protecting against both future infection - and subsequent transmission - than any protection I could have gained by vaccination.
YMMV. I suspect this is down to those who have had mild Covid pre-vaccination and those who have not.
Some of us didn't even know we had had Covid until afterwards, others think the vaccine saved them from an untimely death/hospitalisation.
