Re: Covid Vaccine: Will you get it?

The question on transmission is an interesting one, if the current crop of vaccines fails to reduce transmission there is still the option of intranasal vaccine sprays. The conventional vaccine is given in muscle far away from the nose so it relies on the production of circulating antibodies being formed in the blood, some of which will make its way towards the nose to neutralise the virus.

Whether that is enough to tackle the reservoir of rapidly dividing viruses up there is the billion dollar question. What a vaccine spray would do is give you much more localised mucosal immunity (the lining of the nasal passages) and that should solve the problem once and for all.
