We lost my wife's brother (for the serial dim wits that was my brother in-law), and his daughter (our niece) to covid.
There have been screeds of debates over the last few years, both here and around the world, as to the effectiveness of vaccines, and if masks, social distancing, washing / dissinfecting hands etc. actually work. We have been lucky enough, so far to avoid it but it is real and it is out there. However, we did follow protocol and advice from medical experts regarding all of the precautions and I seriously believe that - that did help in neither of us contracting Covid.
We still have the conspiracy theorists and those that refuse to wear masks because they are petulent over being forced to previously, but I still believe that doing something to try and protrect yourself and your family is better than doing nothing. No harm in at least trying to be sensible is there?
