The corona virus component of the seasonal flu vaccine?I was thinking of corona virus component ...
It's been posted that some here are pessimistic about a covid-19 vaccine because there has never been a licensed corona virus vaccine for any flavour of corona virus.
You have some references to how an experimental vaccine is being blended into the seaonal flu vaccine?
Other references say that for corona virus, four that can affect humans cause the common cold with mild to moderate symptoms. A biotech fund guy referred to that when explaining why there was no funding for a corona virus vaccine. He also said that it would require something that covered all four where if it was 100% effective (not likely) it would take care of about 20% of the common cold cases. According to him, that put the market too small to take care of the costs and hope for a profit.
It still seems to me to be comparing apples to oranges that does not tell us much of anything.
That's a possiblity ... but a different question than the initial vaccine's effectiveness. And a key part IMO will be whether like tetanus a booster shot is needed or as you seem to be assuming, a new vaccine is required.... another example “Infectious bronchitis virus (IBV) is a widespread avian coronavirus, whose control relies mainly on extensive vaccine administration. Unfortunately, the continuous emergence of new vaccine-immunity escaping variants prompts the development of new vaccines.
in my understanding even if vaccine miraculously effective, it will be short lived before another shot is needed.
What's the mutation rate for IBV versus covid-19?
If it's fast, IBV may not be a good predictor considering influenza is significantly faster than covid-19 to change.
Sure ... but skipping it in that year was not seen as potentially causing a major disruption to one's life.... Now, how many people bothered with annual influenza vaccine.
- Too few Canadian adults (38%) got vaccinated in the 2017-2018 season. Therefore I predict corona virus is here to stay
