Well, I was smack dab in the middle of all that went on in Washington and all its issues including reading hundreds of letters about every public issue on or off the table, and I never heard of the swine flu in the 70's nor a vaccine. Not saying it didn't exist, just saying it wasn't front page, second page or editorial page. I was also required to skim the congressional record, and if this was an issue, it covered very little print territory and broadcast news
