LUBBOCK, TX (KCBD) - There is preliminary evidence that last year's seasonal flu shot may have protected some people from the swine flu, but experts say that's no reason to forego the H1N1 vaccine this year.
You may remember H1N1 cases first started popping up earlier this year in Mexico. Researchers there looked at data on 240 patients and say those who did not become sick with swine flu were more likely to have received the seasonal flu shot the year before.
The shot appears to have given some protection against the most severe forms of swine flu, but researchers say many more studies need to be done, and say it's unlikely this year's seasonal flu shot will also protect against swine flu.
