While it might be a shock or even alarm antiVAXers (that the Covid-19 vaccine does not provide instant protection against SARS-CoV-2) the scientific reality is that no vaccine treatment will ever provide instant protection.
It is physiologically impossible to do so.
This news item yet again highlights the need for vigilance.
Sadly and predictably, it also points to the ignorance of antiVAXers and their cult like desire to believe another causal reality exists despite decades long scientific proof that utterly refutes their false assertions.
