One of the discoverers of the HIV virus, Dr Robert Gallo,
suggests getting FluMist influenza spray vaccine this year
because it is a “live attenuated virus vaccine”
like Measles vaccine, Polio vaccine or BCG vaccine.
He says that those who get FluMist sprayed up their nose might gain somewhat more protection against Covid-19.
