Wall Street Journal Wednesday has a guest column by Dr Robert Gallo and Daniel Arbessa advocating giving the general USA population the Sabin Oral Polio Vaccine to boost the “innate immune system” against Covid-19.

Dr Gallo reminds that past researchers found that the Sabin vaccine meant for polio surprisingly also reduces Influenza by 3.8 fold. Dr Gallo then mentions that the Measles vaccine has also been found to reduce infection by other viruses too.

This is similar to a previous post in this thread.
