It's now starting to look like the government may have no choice but full lock down again.
Worse than that the ongoing testing shows that a large number of people lose their antibodies within three months. that means that early antivirus options might not be as effective as hoped, people could still catch it but suffer less severe symptoms.
That would also mean that herd immunity is a pipe dream without a vaccine that is cheap and effective for at least a few months. There are other ways the body can identify infections but we don't know how much difference those will make. The good part is that hospital staff have learned what treatments work better and when to use them.
Had the government gone all out for herd immunity earlier this year like they wanted it would have cost about 400,000 deaths and we would still have the virus.
