Hopefully, just the start with others coming into being. As there is, at present, no knowledge as to how long the immunity lasts, it could well become, like the 'flu' jab, something that need doing annually.
For a long time I was a little pessimistic about getting a vaccine before about 2025, but am now more optimistic about this.
With vaccines, hopefully our lives can slowly start to return to the 'old normal'.
Okay.......I am now waiting for all those coming on to say they would not risk taking this, etc. etc. etc.
