World Health Organization chief scientist Soumya Swaminathan said:
I don’t believe we have the evidence on any of the vaccines to be confident that it’s going to prevent people from actually getting the infection.
What is a vaccine then? If not to prevent infection?
She also said:
I would say in a four to five-year timeframe we could be looking at controlling this.
I do not understand how these vaccines can contribute to herd immunity when they may not even provide immunity. When they may not prevent transmission.
In the spring, when the weather warms and people go back outside, will the case numbers drop? Will fewer cases be a result of weather or vaccinations?
Nonetheless, even with an effective vaccine, even with herd immunity, “the destiny of the virus is to become endemic,” that is, regularly found in populations for several years.
