The UK Government will facilitate twice weekly “lateral flow” Covid Antigen testing for virtually anyone who is asymptomatic for Covid, and arrange PCR testing for those with Covid symptoms.
What they won’t do is facilitate Covid antibody testing, leaving no possibility for certification of natural immunity.
An intelligent approach to deciding on the pros and cons of vaccination is to look for natural immunity before getting the vaccine, and if you are naturally immune, it then makes sense to avoid taking an experimental and potentially fatal vaccine.
The Uk Government does not want people doing this; it wants everyone vaccinated, regardless of natural immunity.
The question is why?
