My post states early spring as the time that the virus will fade away.
Now in mid April numbers are dropping rapidly, as expected by some, me amongst them.
Public Health England, as you know, is the government's advisory body on health matters.
They have published a guide to the vaccine that states that they don't know if it will stop you getting Covid 19 or passing it on, only that they think it will reduce the severity of the disease if you do get it.
The long term effects of the vaccine are unknown as it hasn't had the key test, the passage of time.
